What is Migraine and How to Treat it ?

What are migraines?

Migraines are a recurring type of headache. They cause moderate to severe pain that is throbbing or pulsing. The pain is often on one side of your head. You may also have other symptoms, such as nausea and weakness. You may be sensitive to light and sound.

What causes migraines?

Researchers believe that migraine has a genetic cause. There are also a number of factors that can trigger a migraine. These factors vary from person to person, and they include

  • Stress
  • Anxiety
  • Hormonal changes in women
  • Bright or flashing lights
  • Loud noises
  • Strong smells
  • Medicines
  • Too much or not enough sleep
  • Sudden changes in weather or environment
  • Overexertion (too much physical activity)
  • Tobacco
  • Caffeine or caffeine withdrawal
  • Skipped meals
  • Medication overuse (taking medicine for migraines too often)

Some people have found that certain foods or ingredients can trigger headaches, especially when they are combined with other triggers. These foods and ingredients include

  • Alcohol
  • Chocolate
  • Aged cheeses
  • Monosodium glutamate (MSG)
  • Some fruits and nuts
  • Fermented or pickled goods
  • Yeast
  • Cured or processed meats

Who is at risk for migraines?

About 12% of Americans get migraines. They can affect anyone, but you are more likely to have them if you

  • Are a woman. Women are three times more likely than men to get migraines.
  • Have a family history of migraines. Most people with migraines have family members who have migraines.
  • Have other medical conditions, such as depression, anxiety, bipolar disorder, sleep disorders, and epilepsy.

What are the symptoms of migraines?

There are four different phases of migraines. You may not always go through every phase each time you have a migraine.

  • Prodome. This phase starts up to 24 hours before you get the migraine. You have early signs and symptoms, such as food cravings, unexplained mood changes, uncontrollable yawning, fluid retention, and increased urination.
  • Aura. If you have this phase, you might see flashing or bright lights or zig-zag lines. You may have muscle weakness or feel like you are being touched or grabbed. An aura can happen just before or during a migraine.
  • Headache. A migraine usually starts gradually and then becomes more severe. It typically causes throbbing or pulsing pain, which is often on one side of your head. But sometimes you can have a migraine without a headache. Other migraine symptoms may include
    • Increased sensitivity to light, noise, and odors
    • Nausea and vomiting
    • Worsened pain when you move, cough, or sneeze
  • Postdrome (following the headache). You may feel exhausted, weak, and confused after a migraine. This can last up to a day.

Migraines are more common in the morning; people often wake up with them. Some people have migraines at predictable times, such as before menstruation or on weekends following a stressful week of work.

What is the Triggers of Migraine ?

Some common migraine triggers include:

  • Hormone changes. Many women notice that they have headaches around their period, while they’re pregnant, or when they’re ovulating. Symptoms may also be tied to menopause, birth control that uses hormones, or hormone replacement therapy.
  • Stress. When you’re stressed, your brain releases chemicals that can cause blood vessel changes that might lead to a migraine.
  • Foods. Some foods and drinks, such as aged cheese, alcohol, and food additives like nitrates (in pepperoni, hot dogs, and lunchmeats) and monosodium glutamate (MSG), may be responsible in some people.
  • Skipping meals
  • Caffeine. Getting too much or not getting as much as you’re used to can cause headaches. Caffeine itself can be a treatment for acute migraine attacks.
  • Changes in weather. Storm fronts, changes in barometric pressure, strong winds, or changes in altitude can all trigger a migraine.
  • Senses. Loud noises, bright lights, and strong smells can set off a migraine.
  • Medications. Vasodilators, which widen your blood vessels, can trigger them.
  • Physical activity. This includes exercise and sex.
  • Tobacco
  • Changes to your sleep. You might get headaches when you sleep too much or not enough.

What is Migraine Types ?

Migraine can be classified into subtypes, according to the headache classification committee of the International Headache Society:

  • Migraine without aura is a recurrent headache attack of 4 to 72 hours; typically unilateral in location, pulsating in quality, moderate to severe in intensity, aggravated by physical activity, and associated with nausea and light and sound sensitivity (photophobia and phonophobia).
  • Migraine with aura has recurrent fully reversible attacks, lasting minutes, typically one or more of these unilateral symptoms: visual, sensory, speech and language, motor, brainstem, and retinal, usually followed by headache and migraine symptoms.
  • Chronic migraine is a headache that occurs on 15 or more days in a month for more than three months and has migraine features on at least eight or more days in a month.
  • Complications of migraine

    • Status migrainosus is a debilitating migraine attack that lasts more than 72 hours.
    • Persistent aura without infarction is an aura that persists for more than one week without evidence of infarction on neuroimaging.
    • Migrainous infarction is one or more aura symptoms associated with brain ischemia on neuroimaging during a typical migraine attack.
    • Migraine aura-triggered seizure occurs during an attack of migraine with aura, and a seizure is triggered.
  • Probable migraine is a symptomatic migraine attack that lacks one of the features required to fulfill criteria for one of the above and does not meet the criteria for another type of headache.

Episodic syndromes that may be associated with migraine

  • Recurrent gastrointestinal disturbances are recurrent attacks of abdominal pain and discomfort, nausea, and vomiting that may be associated with migraines.
  • Benign paroxysmal vertigo has brief recurrent attacks of vertigo.
  • Benign paroxysmal torticollis is recurrent episodes of head tilt to one side.

How are migraines diagnosed?

For migraines without aura, diagnostic criteria include:

  1. 5+ attacks fulfilling the other criteria
  2. Headache attacks that last from 4 to 72 hours (untreated or unsuccessfully treated)
  3. Headache consisting of at least 2 of the following characteristics: unilateral location, pulsating quality, moderate/severe pain intensity, and aggravation by or causing avoidance of routine physical activity (i.e., walking or climbing stairs)
  4. During the headache, the presence of at least one of the following: nausea/vomiting, photophobia/phonophobia
  5. Not better accounted for with another ICHD-3 diagnosis

For migraines with aura, diagnostic criteria include:

  1. Two or more attacks fulfilling the other criteria
  2. At least one of the following completely reversible symptoms of aura: visual, sensory, motor, speech or language, brainstem, retinal
  3. At a minimum of three of the following six characteristics: 1+ one aura symptoms spread gradually over greater than equal to 5 minutes, 2+ aura symptoms occur in succession, each aura symptom lasts 5-60 minutes, 1+ aura symptom is unilateral, 1+ aura symptom is positive, the aura is accompanied or followed within 60 minutes by the headache
  4. Not better accounted for with another ICHD-3 diagnosis

For chronic migraine, diagnostic criteria include:

  1. Headache (migraine-like or tension-type-like) on greater than or equal to 15 days/month for greater than three months and also fulfilling criteria B and C
  2. Occurring in a patient who has experienced at least five attacks fulfilling criteria B through D for migraine presenting without aura and/or criteria B and C for migraine that presents with aura
  3. Occurs greater than or equal to 8 days/month for greater than three months, fulfilling any of the following
  4. Criteria C and D for migraine without aura
  5. Criteria B and C for migraine with aura
  6. Believed by the patient to be migraine at the point of onset and relieved by a triptan or ergot derivative
  7. Not better accounted for with another ICHD-3 diagnosis

How are migraines treated?

There is no cure for migraines. Treatment focuses on relieving symptoms and preventing additional attacks.

There are different types of medicines to relieve symptoms. They include triptan drugs, ergotamine drugs, and pain relievers. The sooner you take the medicine, the more effective it is.

There are also other things you can do to feel better:

  • Resting with your eyes closed in a quiet, darkened room
  • Placing a cool cloth or ice pack on your forehead
  • Drinking fluids

There are some lifestyle changes you can make to prevent migraines:

  • Stress management strategies, such as exercise, relaxation techniques, and biofeedback, may reduce the number and severity of migraines. Biofeedback uses electronic devices to teach you to control certain body functions, such as your heartbeat, blood pressure, and muscle tension.
  • Make a log of what seems to trigger your migraines. You can learn what you need to avoid, such as certain foods and medicines. It also help you figure out what you should do, such as establishing a consistent sleep schedule and eating regular meals.
  • Hormone therapy may help some women whose migraines seem to be linked to their menstrual cycle
  • If you have obesity, losing weight may also be helpful

If you have frequent or severe migraines, you may need to take medicines to prevent further attacks. Talk with your health care provider about which drug would be right for you.

Certain natural treatments, such as riboflavin (vitamin B2) and coenzyme Q10, may help prevent migraines. If your magnesium level is low, you can try taking magnesium. There is also an herb, butterbur, which some people take to prevent migraines. But butterbur may not be safe for long-term use. Always check with your health care provider before taking any supplements.

What is the Medicines for Migraine ?

1) Abortive Treatments

1.Anti-inflammatories (NSAIDs and Acetaminophen)

Non-steroidal anti-inflammatory drugs (NSAIDs) are mainstay choices and have the greatest strength of evidence. Ibuprofen, naproxen sodium, acetylsalicylic acid (ASA), and diclofenac potassium all have double-blinded randomized controlled trial evidence for efficacy that has analysis in systematic reviews.

NSAIDs include aspirin, naproxen, ibuprofen, tolfenamic acid, diclofenac, piroxicam, ketoprofen, and ketorolac.

Acetaminophen and the combination of acetaminophen/aspirin/caffeine have also demonstrated consistent evidence of efficacy for acute migraine.

Mechanism of Action

NSAIDs inhibit prostaglandin synthesis. NSAIDs reversibly inhibit cyclooxygenase (COX) 1 and 2. The NSAIDs that inhibit prostaglandin E2 synthesis are effective in treating acute migraine attacks. Aspirin acts as an irreversible COX I and 2 inhibitor.

Although not entirely understood, the current thought is that acetaminophen affects central processes, such as positive effects on the serotonergic descending inhibitory pathways. It also may affect opioidergic systems, eicosanoid systems, and the nitric oxide-containing pathways.

Administration

  • Aspirin: Peroral (PO) tablet with standard dosages of 325 mg, 500 mg, and 400 mg effervescent; treatment dosage of up to 1000 mg
  • Naproxen: PO tablet with standard dosages of 220 mg, 275 mg, 500 mg, and 550 mg; treatment dosage of 550 to 1100 mg per day in divided dosages
  • Ibuprofen: PO tablet with standard dosages of 200 mg, 400 mg, 600 mg, and 800 mg; treatment dosage of 200 to 800 mg
  • Tolfenamic acid: PO tablet with standard and treatment dosage of 200 mg
  • Diclofenac: PO tablet with standard dosages of 50 mg; treatment dosage of 50 to 100 mg
  • Piroxicam: PO capsules with standard dosages of 10 mg, 20 mg; treatment dosage of 40 mg
  • Ketorolac: Parenteral dosing with standard dosages of 30 to 60 mg; treatment dose of 30 to 60 mg

Adverse Effects

The most common adverse effects of NSAIDs are GI symptoms, which include dyspepsia, abdominal burning or discomfort, and diarrhea. Other less common symptoms include easy bruising, pruritus, rash, hypersensitivity response in asthmatics, gastritis, esophagitis, GI bleeding, renal failure, hepatic impairment, and cardiovascular events.

Besides allergic reactions, no serious side effects have been observed with acetaminophen when taken in appropriate dosages. After higher doses or prolonged duration of taking acetaminophen, hepatotoxicity, and nephrotoxicity (less common) can occur.

Contraindications

In addition to NSAID hypersensitivity reaction, another agreed-upon absolute contraindication is for those in the preoperative period of coronary artery bypass graft surgery. Warnings include those with significant cardiovascular disease, renal insufficiency, gastrointestinal erosive disorders, bleeding diathesis, and those taking warfarin.

For acetaminophen, contraindications include hypersensitivity reactions and severe active liver disease.

2.Triptans

Seven triptans have approval from the FDA and marketed for acute treatment of migraines They include sumatriptan, eletriptan, naratriptan, zolmitriptan, rizatriptan, frovatriptan, and almotriptan. Triptans are significantly more expensive than NSAIDs as a class. They are often therapeutic choices if other therapies have failed (i.e., NSAID, acetaminophen) or if the headache is severe.

Mechanism of Action

Triptans are serotonin-receptor agonists with a high affinity for 5-HT1B and 5-HT1D receptors, and variable affinity for 5-HT1F receptors. The proposed mechanism of action involves binding postsynaptic 5-HT1B receptors on the smooth muscle cells of blood vessels and presynaptic 5-HT1D receptors on the trigeminal nerve terminals and dorsal horn neurons.

Administration

Sumatriptan: PO tablet with standard dosages of 100, 50, and 25 mg; also available parenteral (though IV contraindicated because of its potential to cause vasospasm)

Eletriptan: PO tablet with standard dosages of 40 and 20 mg; contraindicated in patients with renal failure, arrhythmias, and heart failure

Naratriptan: PO tablet with standard dosages of 2.5 and 1 mg; has a sulfa group

Zolmitriptan: PO tablet with standard dosages of 5 and 2.5 mg; also available as wafer and nasal spray; wafer contains phenylalanine

Rizatriptan: PO tablet with standard dosages of 10 and 5 mg; also available as a wafer; wafer contains phenylalanine

Frovatriptan: PO tablet with a standard dose of 2.5 mg

Almotriptan: PO tablet with standard dosages of 12.5 and 6.25 mg; has a sulfa group

Adverse Effects

The most common adverse effects of triptans include pressure or tightness sensations of the chest, throat, or jaw; limb heaviness; myalgias; and fatigue. Less common adverse effects include flushing, paresthesias, dizziness, asthenia, and mental cloudiness.

Contraindications

Triptans have associations with increased blood pressure, and providers should avoid giving them to patients with uncontrolled hypertension, ischemic cardiac syndrome, cerebrovascular syndrome, or peripheral vascular condition. Patients should also not take them within 24 hours of administration, another triptan, or ergot-type medication. Triptans are also contraindicated in hemiplegic or basilar migraine and patients with hepatic impairment.

3.Antiemetics

When a migraine is associated with nausea/vomiting, an antiemetic is an excellent choice for treatment. The administration of an antiemetic is often in combination with either an NSAID or triptan, but can be used as monotherapy. Two common antiemetics used include metoclopramide and prochlorperazine. Metoclopramide has the greatest evidence for efficacy in migraine and is associated with a less likelihood of extrapyramidal side effects than prochlorperazine, but both are good initial options. Domperidone, promethazine, chlorpromazine are other examples of antiemetics.

Mechanism of Action

Metoclopramide is a benzamide that antagonizes the D2 receptor at lower doses and 5HT-3 at higher doses.

Prochlorperazine and chlorpromazine are dopamine antagonists (D2 receptor), providing antiemetic and migraine relief effects.

Administration

Metoclopramide: PO and parenteral formulations available; treatment dosages of 10 – 20 mg

Prochlorperazine: PO, parenteral and rectal formulations available; treatment dosage of 10 mg (PO and parenteral) and 25 mg (rectal)

Chlorpromazine: PO and parenteral formulations available; treatment dosage of 0.1 mg/kg up to 25 mg

Adverse Effects

Most antiemetics used for migraines are associated with a risk of QT interval prolongation and torsades de pointes. Metoclopramide, prochlorperazine, and chlorpromazine can cause dystonia, tardive dyskinesia, and akathisia (collectively known as extrapyramidal symptoms). Coadministration with diphenhydramine can prevent these symptoms. Other side effects are uncommon and can include headaches and allergic reactions such as anaphylaxis.

Contraindications

Considering the dopamine antagonists, contraindications include known hypersensitivity reactions and know extrapyramidal symptom reactions.

4.Ergotamines

Triptans have largely replaced ergotamines, as studies have shown more efficacy for triptans. Dihydroergotamine has demonstrated some efficacy, while the effectiveness of ergotamine is uncertain. In one systematic review, dihydroergotamine was not as effective as triptans, but when combined with an antiemetic, was found to be as effective as ketorolac, opiates, or valproate.  Dihydroergotamine may be a useful option when patients do not respond to other medications, including triptans.

Mechanism of Action

Ergotamines, like triptans, are potent 5-HT 1b/1d receptor agonists. They involve constricting the theorized pain-producing intracranial extracerebral blood vessels at the 5-HT1B receptors and inhibit the trigeminal neurotransmission at both peripheral and central 5-HT1D receptors. They also interact with other serotonin, adrenergic, and dopamine receptors. They cause constriction of peripheral and cranial blood vessels.

Administration

Dihydroergotamine: Parenteral dosing with dosages between 0.5 – 1 mg; intranasal formulation available (4 mg)

Adverse Effects

The most common side effects include nausea and vomiting. Administer with an antiemetic. Dysphoria is another observed side effect (central 5-HT1A agonism).

Contraindications

Similar to triptans, those with cardiovascular disease should avoid the use of ergotamines. The peripheral vascular constrictive effects of ergotamines are more pronounced than triptans since triptans do not have activity at adrenergic and 5-HT2A receptors.

2)Preventive Treatments

1.Beta-Blockers

Propranolol, timolol, bisoprolol, metoprolol, atenolol, and nadolol have shown positive outcomes in migraine prevention studies. Beta-blockers with intrinsic sympathomimetic activity (such as acebutolol, alprenolol, oxprenolol, and pindolol) are not effective for migraine prevention.

Administration

Propranolol: PO immediate-release and long-acting formulations available; dose for immediate release ranging from 80 to 240 mg/day divided every 6 to 8 hours; dose for long-acting release is 80 to 240 mg/day

Timolol: PO formulation with doses of 20-30 mg/day

Bisoprolol: PO formulation with doses of 2.5 to 10 mg/day

Metoprolol: PO formulation with doses of 50 to 200 mg/day twice daily

Atenolol: PO formulation with doses of 50 to 200 mg/day

Nadolol: PO formulation with doses of 40 to 240 mg/day

Mechanism of Action

The mechanisms of action of beta-blockers in migraine prevention are not entirely understood. The thinking is that the beta-1 mediated effects could inhibit noradrenaline release and tyrosine hydroxylase activity, accounting for prophylactic action. Other possibilities include serotonergic blockade, inhibiting thalamic activity, and nitrous oxide blockade.

Adverse Effects

Common adverse effects include drowsiness, fatigue, dizziness, and weakness. Other adverse effects include weight gain, symptomatic hypotension, nausea/vomiting, diarrhea, feelings of coldness in extremities, and dry skin/mouth/eyes, bradycardia, bronchospasm, dyspnea, alopecia, visual disturbances, insomnia, sexual dysfunction, and metabolism alterations.

Contraindications

Asthma and chronic obstructive pulmonary disease have been classic contraindications because of the potential for beta-blockers to cause bronchospasm. Cocaine intoxication is another contraindication because of the risk of coronary vasospasm. This contraindication is subject to debate.

2.Antiepileptics

Several antiepileptic drugs (AEDs) have been studied and proven effective for migraine prevention, with topiramate and valproate having the best evidence.

Administration

Topiramate: PO formulation with doses of 25-200 mg/day

Valproate: PO formulation of extended (once daily) and delayed (2 divided doses daily) releases are available; doses of 500-1500 mg/day

Mechanism of Action

Similar to the beta-blockers, it is unclear what effect antiepileptics have on migraine prevention. For topiramate, it blocks multiple channels such as voltage-dependent sodium and calcium channels. It also has been shown to inhibit glutamate-mediated excitatory neurotransmission, facilitate GABA-A-mediated inhibition, inhibit carbonic anhydrase activity, and reduce CGRP secretion from trigeminal neurons. For valproate, similar to topiramate, multiple mechanisms may contribute to migraine prevention. They include enhancing GABAergic inhibition, blocking excitatory ion channels, and downregulating the expression of CGRP in brain tissue.

Adverse Effects

Common adverse effects of topiramate include nausea/vomiting, diarrhea, somnolence, dizziness, weight loss, paresthesias, fatigue, nasopharyngitis, and weight loss. Other adverse effects include tachypnea, palpitations, bleeding, mood changes, dysuria, hematuria, and increased frequency of urination.

Common adverse effects of valproate include nausea/vomiting, diarrhea, abdominal pain, headache, drowsiness, hair loss, tremors, dizziness, visual disturbances, tinnitus, changes in appetite, and weight gain. Other adverse effects include confusion, severe drowsiness, bleeding, and inflammation.

Contraindications

Hypersensitivity to topiramate is a contraindication to the drug.

Contraindications to valproate usage include hepatic dysfunction, mitochondrial disorders, hypersensitivity, urea cycle disorders, and pregnancy.

3.Calcium Channel Blockers

Flunarizine is the best studied of the calcium channel blockers for migraine prevention (however not available in the U.S.). Verapamil and cinnarizine are other meds that are off-label for migraine prevention. Verapamil is probably the most commonly used calcium channel blocker for migraine prevention in the U.S.

Administration

Flunarizine: PO formulation of 5 to 10 mg/day

Verapamil: PO formulation of 120 to 480 mg/day in 3 divided doses

Mechanism of Action

Similar to the other migraine preventive treatments, the role of calcium channel blockers in migraine prevention is unclear. Flunarizine is a nonselective calcium antagonist. In addition to calcium channel activity, it blocks voltage-gated sodium channels, acts as a D2 dopamine antagonist, and increases leptin levels.

Adverse Effects

Adverse effects include constipation, cardiac conduction defects at higher doses, dizziness, constipation, headache, nausea/vomiting, flushing, edema, drowsiness, and hypotension. Lesser common adverse effects include sexual dysfunction, gingival overgrowth, and liver dysfunction.

Contraindications

Contraindications include hypersensitivity reactions, acute coronary syndrome, hypertrophic obstructive cardiomyopathy, severe stenotic heart valve defects, and cardiac conduction disorders.

4.Antidepressants

The most studied antidepressants that have shown efficacy for migraine prevention are the tricyclic antidepressant (TCA) amitriptyline and the selective serotonin reuptake inhibitor (SSRI) fluoxetine. Other TCAs and the serotonin-norepinephrine reuptake inhibitor venlafaxine have been studied and may be effective for migraine prevention, though the evidence is short.

Administration

Amitriptyline: PO formulation of 10 to 150 mg/day

Fluoxetine: PO formulation of 20 to 40 mg/day

Mechanism of Action

Similar to other migraine prevention medications, the role of antidepressants in migraine prevention is unclear. Amitriptyline is a mixed serotonin-norepinephrine reuptake inhibitor and has the following mechanisms: alpha2-adrenoceptor agonist, sodium channel blockade contributing to antimuscarinic and antihistamine effects, and cortical spreading depression.

Fluoxetine is a selective serotonin reuptake inhibitor leading to increased levels of serotonin. Noradrenaline reuptake inhibition occurs at higher doses.

Adverse Effects

Adverse effects of tricyclic antidepressants include antimuscarinic effects such as dry mouth, blurry vision, constipation, urinary retention, increased body temperature, and excessive sweating. Other side effects include morning sedation, tachycardia, vivid dreams, weight gain, hypotension, sexual dysfunction, confusion, and QT prolongation.

Adverse effects of selective serotonin reuptake inhibitors include sexual dysfunction, drowsiness, weight gain, insomnia, dizziness, headache, dry mouth, blurry vision, nausea, rash, tremors, and constipation. SSRIs can also prolong the QT interval.

Contraindications

For TCAs, coadministration with monoamine oxidase inhibitors (MAOI) is contraindicated due to the increased risk of serotonin syndrome. Hypersensitivity reactions and coadministration of cisapride are also contraindicated.

For SSRIs, coadministration of medications that significantly increase the risk of serotonin syndrome is contraindicated. These medications include monoamine oxidase inhibitors, linezolid, and methylene blue. Other contraindications include hypersensitivity reactions and coadministration with pimozide or thioridazine.

3) Other and Future Considerations

1.Triptans with NSAIDs

Research has shown the combined use of a triptan and an NSAID to be more effective than using either drug class alone for acute migraine treatment. The best-studied combination is sumatriptan plus naproxen PO. The two classes of drugs having different mechanisms of action are thought to provide better relief. Multiple studies have used sumatriptan 85 mg plus naproxen 500 mg and sumatriptan 50 mg plus naproxen 500 mg. In a meta-analysis review article, no significant difference was found between using the sumatriptan 85 mg – naproxen combo and the sumatriptan 50 mg – naproxen combo.

2.Lasmiditan

Lasmiditan is a serotonin 5-HT1F receptor agonist that has been shown effective for acute migraine treatment. The utility of this medication is that it lacks vasoconstrictor effects such as those seen in triptans, and thus offers those with cardiovascular disease an alternative to triptans. Studies have used up to lasmiditan 200 mg PO with good effect; however, there were frequent reports of adverse effects. In a recent phase, three multicenter, double-blind, randomized controlled studies, between 25.4% to 39.0% of patients receiving lasmiditan reported adverse effects. The most common adverse effects were dizziness, somnolence, and paresthesias.

3.Calcitonin Gene-Related Peptide (CGRP)

CGRP monoclonal antibodies (mAbs) are the only class of currently used preventives explicitly developed for the treatment of migraines. The current thinking is that CGRP mediates the vasodilatory component of neurogenic inflammation, as CGRP is a widely distributed vasodilator. The CGRP mAbs target either the CGRP molecule itself or the CGRP receptor. In network meta-analysis, the CGRP mAbs seemed to be as effective as other preventive treatments, but have fewer side effects. Long-term data on safety, however, is limited.  These medications include erenumab, fremanezumab, and galcanezumab.

Complementary and alternative treatments

Some people get relief with therapies they use in addition to or instead of traditional medical treatment. These are called complementary or alternative treatments. For migraine, they include:

  • Biofeedback. This helps you take note of stressful situations that could trigger symptoms. If the headache begins slowly, biofeedback can stop the attack before it becomes full-blown.
  • Cognitive behavioral therapy (CBT). A specialist can teach you how actions and thoughts affect how you sense pain.
  • Supplements. Research has found that some vitamins, minerals, and herbs can prevent or treat migraines. These include riboflavin, coenzyme Q10, and melatonin. Butterbur may head off migraines, but it can also affect your liver enzymes.
  • Body work. Physical treatments like chiropractic, massage, acupressure, acupuncture, and craniosacral therapy might ease headache symptoms.

Talk to your doctor before trying any complementary or alternative treatments.

How are migraines treated?

Migraine headaches are chronic. They can’t be cured, but they can be managed and possibly improved. There are two main treatment approaches that use medications: abortive and preventive.

  • Abortive medications are most effective when you use them at the first sign of a migraine. Take them while the pain is mild. By possibly stopping the headache process, abortive medications help stop or decrease your migraine symptoms, including pain, nausea, light sensitivity, etc. Some abortive medications work by constricting your blood vessels, bringing them back to normal and relieving the throbbing pain.
  • Preventive (prophylactic) medications may be prescribed when your headaches are severe, occur more than four times a month and are significantly interfering with your normal activities. Preventive medications reduce the frequency and severity of the headaches. Medications are generally taken on a regular, daily basis to help prevent migraines.

What medications are used to relieve migraine pain?

Over-the-counter medications are effective for some people with mild to moderate migraines. The main ingredients in pain relieving medications are ibuprofen, aspirin, acetaminophen, naproxen and caffeine.

Three over-the-counter products approved by the Food and Drug Administration for migraine headaches are:

  • Excedrin® Migraine.
  • Advil® Migraine.
  • Motrin® Migraine Pain.

Be cautious when taking over-the-counter pain relieving medications. Sometimes overusing them can cause analgesic-rebound headaches or a dependency problem. If you’re taking any over-the-counter pain medications more than two to three times a week, report that to your healthcare provider. They may suggest prescription medications that may be more effective.

Prescription drugs for migraine headaches include:

Triptan class of drugs (these are abortives):

  • Sumatriptan.
  • Zolmitriptan.
  • Naratriptan.

Calcium channel blockers:

  • Verapamil.

Calcitonin gene-related (CGRP) monoclonal antibodies:

  • Erenumab.
  • Fremanezumab.
  • Galcanezumab.
  • Eptinezumab.

Beta blockers:

  • Atenolol.
  • Propranolol.
  • Nadolol.

Antidepressants:

  • Amitriptyline.
  • Nortriptyline.
  • Zanaflex
  • Doxepin.
  • Venlafaxine.
  • Duloxetine.
  • Flexeril
  • Robaxin

Antiseizure drugs:

  • Valproic acid.
  • Topiramate.
  • Gabapentin (Neurontin )

Other:

  • Steroids.
  • Phenothiazines.
  • Corticosteroids.

Your healthcare provider might recommend vitamins, minerals, or herbs, including:

Drugs to relieve migraine pain come in a variety of formulations including pills, tablets, injections, suppositories and nasal sprays. You and your healthcare provider will discuss the specific medication, combination of medications and formulations to best meet your unique headache pain.

Drugs to relieve nausea are also prescribed, if needed.

All medications should be used under the direction of a headache specialist or healthcare provider familiar with migraine therapy. As with any medication, it’s important to carefully follow the label instructions and your healthcare provider’s advice.

Alternative migraine management methods, also known as home remedies, include:

  • Resting in a dark, quiet, cool room.
  • Applying a cold compress or washcloth to your forehead or behind your neck. (Some people prefer heat.)
  • Massaging your scalp.
  • Yoga.
  • Applying pressure to your temples in a circular motion.
  • Keeping yourself in a calm state. Meditating.
  • Biofeedback.

What is Fibromyalgia and How to Treat Fibromyalgia ?

What is Fibromyalgia?

Fibromyalgia

Fibromyalgia (fi·bro·my·al·gi·a) is a condition that causes pain all over the body (also referred to as widespread pain), sleep problems, fatigue, and often emotional and mental distress. People with fibromyalgia may be more sensitive to pain than people without fibromyalgia.

This is called abnormal pain perception processing. Fibromyalgia affects about 4 million US adults, about 2% of the adult population. The cause of fibromyalgia is not known, but it can be effectively treated and managed.

Fibromyalgia is a clinical entity characterized by the combination of ill-defined symptoms including chronic widespread pain, with concomitant fatigue, sleeping disorders and cognitive disturbances. The severity of these symptoms can vary significantly during the course of the disease. Fibromyalgia has been described as an arbitrarily created syndrome that lies at the extreme end of the spectrum of poly-symptomatic distress.

The term poly-symptomatic was used to emphasize the variety of multiple different symptoms that can be found in fibromyalgia patients, while the distress can have a physical and/or a psychological component. This exact nature of fibromyalgia makes it difficult to be clearly defined, often overlapping with disorders that are characterized by similar symptoms.

It is important to note that fibromyalgia is not an exclusion diagnosis as it can co-exist with other clinical conditions.

What are the Signs and Symptoms of Fibromyalgia?

The most common symptoms of fibromyalgia are

  • Pain and stiffness all over the body
  • Fatigue and tiredness
  • Depression and anxiety
  • Sleep problems
  • Problems with thinking, memory, and concentration
  • Headaches, including migraines

Other symptoms may include:

  • Tingling or numbness in hands and feet
  • Pain in the face or jaw, including disorders of the jaw known as temporomandibular joint syndrome (also known as TMJ)
  • Digestive problems, such as abdominal pain, bloating, constipation, and even irritable bowel syndrome (also known as IBS)

Fibromyalgia is a disorder characterized by widespread musculoskeletal pain accompanied by fatigue, sleep, memory and mood issues. Researchers believe that fibromyalgia amplifies painful sensations by affecting the way your brain processes pain signals.

Symptoms sometimes begin after a physical trauma, surgery, infection or significant psychological stress. In other cases, symptoms gradually accumulate over time with no single triggering event.

Women are much more likely to develop fibromyalgia than are men. Many people who have fibromyalgia also have tension headaches, temporomandibular joint (TMJ) disorders, irritable bowel syndrome, anxiety and depression.

While there is no cure for fibromyalgia, a variety of medications can help control symptoms. Exercise, relaxation and stress-reduction measures also may help.

In general, treatments for fibromyalgia include both medication and self-care. The emphasis is on minimizing symptoms and improving general health. No one treatment works for all symptoms.

What are the Risk factors for Fibromyalgia?

Known risk factors include:

  • Age. Fibromyalgia can affect people of all ages, including children. However, most people are diagnosed during middle age and you are more likely to have fibromyalgia as you get older.
  • Lupus or Rheumatoid Arthritis. If you have lupus or rheumatoid arthritis (RA), you are more likely to develop fibromyalgia.

Some other factors have been weakly associated with the onset of fibromyalgia, but more research is needed to see if they are real. These possible risk factors include:

  • Sex. Women are twice as likely to have fibromyalgia as men.  
  • Stressful or traumatic events, such as car accidents, post-traumatic stress disorder (PTSD)
  • Repetitive injuries. Injury from repetitive stress on a joint, such as frequent knee bending.
  • Illness (such as viral infections)
  • Family history
  • Obesity

How is Fibromyalgia Diagnosed?

Doctors usually diagnose fibromyalgia using the patient’s history, physical examination, X-rays, and blood work.

How is Fibromyalgia Treated?

Fibromyalgia can be effectively treated and managed with medication and self-management strategies. You can learn about self-management strategies in the section below titled How can I improve my quality of life?

Fibromyalgia should be treated by a doctor or team of healthcare professionals who specialize in the treatment of fibromyalgia and other types of arthritis, called rheumatologists. Doctors usually treat fibromyalgia with a combination of treatments, which may include:

  • Medications, including prescription drugs and over-the-counter pain relievers
  • Aerobic exercise and muscle strengthening exercise
  • Patient education classes, usually in primary care or community settings
  • Stress management techniques such as meditation, yoga, and massage
  • Good sleep habits to improve the quality of sleep
  • Cognitive behavioral therapy (CBT) to treat underlying depression. CBT is a type of talk therapy meant to change the way people act or think

In addition to medical treatment, people can manage their fibromyalgia with the self-management strategies described below, which are proven to reduce pain and disability, so they can pursue the activities important to them.

What are the Complications of Fibromyalgia?

Fibromyalgia can cause pain, disability, and a lower quality of life. US adults with fibromyalgia may have complications such as:

  • More hospitalizations. If you have fibromyalgia you are twice as likely to be hospitalized as someone without fibromyalgia.
  • Lower quality of life. Women with fibromyalgia may experience a lower quality of life.
  • Higher rates of major depression. Adults with fibromyalgia are more than 3 times more likely to have major depression than adults without fibromyalgia. Screening and treatment for depression are extremely important.
  • Higher death rates from suicide and injuries. Death rates from suicide and injuries are higher among fibromyalgia patients, but overall mortality among adults with fibromyalgia is similar to the general population.
  • Higher rates of other rheumatic conditions. Fibromyalgia often co-occurs with other types of arthritis such as osteoarthritis, rheumatoid arthritis, systemic lupus erythematosus, and ankylosing spondylitis.

How is Fibromyalgia Treated?

You and your doctor can treat fibromyalgia with medicines, lifestyle changes, and complementary therapy. However, fibromyalgia can be hard to treat. It’s important you find a doctor who is familiar with the disorder and its treatment.

Doctors may prescribe one or more of the following medicines to help treat the symptoms of fibromyalgia:

  • Ibuprofen, aspirin, or naproxen you can buy over the counter.
  • Narcotic medicines to treat severe pain.
  • Duloxetine and minacipran to help the pain and fatigue.
  • Pregabalin to help treat nerve pain.

Making lifestyle changes can also help you manage your fibromyalgia, including:

  • Getting enough sleep.
  • Exercising.
  • Adjusting your work demands.
  • Eating well.

You can also try complementary therapies such as:

  • Massage therapy.
  • Movement therapy.
  • Chiropractic therapy.
  • Acupuncture.
  • Diet supplements.

If you are using or would like to try a complementary therapy you should speak with your doctor, who may know more about if it is safe to try.

Fibromyalgia Medications

Medications can help reduce the pain of fibromyalgia and improve sleep. Common choices include:

  • Pain relievers. Over-the-counter pain relievers such as acetaminophen (Tylenol, others), ibuprofen (Advil, Motrin IB, others) or naproxen sodium (Aleve, others) may be helpful. Your doctor might suggest a prescription pain reliever such as tramadol (Ultram, Conzip). Narcotics are not advised, because they can lead to dependence and may even worsen the pain over time.
  • Antidepressants. Duloxetine (Cymbalta) and milnacipran (Savella) may help ease the pain and fatigue associated with fibromyalgia. Your doctor may prescribe amitriptyline at night to help promote sleep.
  • Anti-seizure drugs. Medications designed to treat epilepsy are often useful in reducing certain types of pain. Gabapentin (Neurontin, Gralise) is sometimes helpful in reducing fibromyalgia symptoms, while pregabalin (Lyrica) was the first drug approved by the Food and Drug Administration to treat fibromyalgia.

Drugs associated with Fibromyalgia

 

How to Treat Fibromyalgia by Gabapentin ?

New research supported by the National Institutes of Health’s National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS) shows that the anticonvulsant medication gabapentin, which is used for certain types of seizures, can be an effective treatment for the pain and other symptoms associated with the common, often hard-to-treat chronic pain disorder, fibromyalgia.

In the NIAMS-sponsored, randomized, double-blind clinical trial of 150 women (90 percent) and men with the condition, Lesley M. Arnold, M.D., director of the Women’s Health Research Program at the University of Cincinnati College of Medicine, and her colleagues found that those taking gabapentin at dosages of 1,200 to 2,400 mg daily for 12 weeks displayed significantly less pain than those taking placebo. Patients taking gabapentin also reported significantly better sleep and less fatigue. For the majority of participants, the drug was well tolerated. The most common side effects included dizziness and sedation, which were mild to moderate in severity in most cases.

NIAMS Director Stephen I. Katz. M.D., Ph.D., remarked that “While gabapentin does not have Food and Drug Administration approval for fibromyalgia1, I believe this study offers additional insight to physicians considering the drug for their fibromyalgia patients. Fibromyalgia is a debilitating condition for which current treatments are only modestly effective, so a study such as this is potentially good news for people with this common, painful condition.”

Fibromyalgia is a chronic disorder characterized by chronic, widespread muscle pain and tenderness, and is frequently accompanied by fatigue, insomnia, depression, and anxiety. It affects three million to six million Americans, mostly women, and can be disabling.

The precise cause of fibromyalgia in not known, but research suggests it is related to a problem with the central nervous system’s processing of pain. As with some other chronic pain conditions, people with fibromyalgia often develop a heightened response to stimuli, experiencing pain that would not cause problems in other people. Yet, unlike many other pain syndromes, there is no physical evidence of inflammation or central nervous system damage.

Although gabapentin has little, if any, effect on acute pain, it has shown a robust effect on pain caused by a heightened response to stimuli related to inflammation or nerve injury in animal models of chronic pain syndromes. Researchers have suspected that it might have the same effect in people with fibromyalgia. The new research, published in the April 2007 edition of Arthritis & Rheumatism, indicates the suspicions were correct.

Although the researchers cannot say with certainty how gabapentin helps reduce pain, Dr. Arnold says one possible explanation involves the binding of gabapentin to a specific subunit of voltage-gated calcium channels on neurons. “This binding reduces calcium flow into the nerve cell, which reduces the release of some signaling molecules involved in pain processing,” she says.

How gabapentin improves sleep and other symptoms is less clear, and there are probably different mechanisms involved in fibromyalgia symptoms. “Gabapentin improved sleep, which is an added benefit to patients with fibromyalgia who often report unrefreshing or disrupted sleep,” Dr. Arnold says.

What is important is that people with fibromyalgia now have a potential new treatment option for a condition with few effective treatments. “Studies like this give clinicians evidence-based information to guide their treatment of patients,” says Dr. Arnold.

Gabapentin Dosage for Fibromyalgia

Twenty-nine studies (3571 participants), studied gabapentin at daily doses of 1200 mg or more in 12 chronic pain conditions; 78% of participants were in studies of postherpetic neuralgia, painful diabetic neuropathy or mixed neuropathic pain. Using the IMMPACT definition of at least moderate benefit, gabapentin was superior to placebo in 14 studies with 2831 participants, 43% improving with gabapentin and 26% with placebo; the NNT was 5.8 (4.8 to 7.2). Using the IMMPACT definition of substantial benefit, gabapentin was superior to placebo in 13 studies with 2627 participants, 31% improving with gabapentin and 17% with placebo; the NNT was 6.8 (5.6 to 8.7). These estimates of efficacy are more conservative than those reported in a previous review. Data from few studies and participants were available for other painful conditions.

Adverse events occurred significantly more often with gabapentin. Persons taking gabapentin can expect to have at least one adverse event (66%), withdraw because of an adverse event (12%), suffer dizziness (21%), somnolence (16%), peripheral oedema (8%), and gait disturbance (9%). Serious adverse events (4%) were no more common than with placebo.

There were insufficient data for comparisons with other active treatments.
