Migraine Medications: Acute Treatments and Preventive Options

Migraine is a neurological disorder characterized by severe, throbbing head pain—often on one side—accompanied by nausea, vomiting, and heightened sensitivity to light and sound. While there is no cure, a variety of medications can relieve attacks and reduce their frequency, improving quality of life.

Acute Migraine Medications

Acute drugs are taken at the onset of an attack to stop or lessen pain and associated symptoms. Using any acute medication on more than 10 days per month can trigger medication‑overuse (rebound) headaches, so discuss alternative strategies with a healthcare professional if you approach this limit.

Pain Relievers (OTC)

Common over‑the‑counter options include:

  • Acetaminophen (Tylenol)
  • Ibuprofen (Advil, Motrin)
  • Naproxen (Aleve)
  • Aspirin
  • Combination products that add caffeine (e.g., Excedrin Migraine)

These agents work best for mild attacks. Long‑term use of NSAIDs can cause stomach irritation, kidney issues, or increased cardiovascular risk, so follow dosing recommendations.

Ergotamines

Ergotamines were the first migraine‑specific drugs. They contract cranial blood vessels by acting on 5‑HT1B and 5‑HT1D receptors. Because newer agents are more effective and safer, ergotamines are reserved for patients who cannot use triptans.

Examples:

  • Dihydroergotamine (DHE‑45, Migranal)
  • Ergotamine (Ergomar)
  • Ergotamine + caffeine (Cafatine, Cafergot, Migergot)

Avoid ergotamines if you are pregnant, have heart disease, or are taking interacting drugs such as certain antifungals or antibiotics.

Triptans

Triptans boost serotonin activity, narrowing dilated blood vessels and reducing inflammation. They are the most widely used prescription treatment for moderate‑to‑severe migraines.

Available forms and common agents:

  • Sumatriptan (oral tablet, nasal spray, subcutaneous injection)
  • Rizatriptan (Maxalt)
  • Zolmitriptan (Zomig)
  • Naratriptan (Amerge)
  • Eletriptan (Relpax)
  • Almotriptan (Axert)

Do not exceed 10 triptan doses per month. Contraindications include uncontrolled hypertension, coronary artery disease, and a history of stroke. Possible side effects: chest tightness, dizziness, and rare serotonin syndrome when combined with other serotonergic drugs (e.g., SSRIs).

CGRP Antagonists (Gepants) – Acute

Gepants block calcitonin gene‑related peptide (CGRP), a key pain mediator in migraine.

  • Rimegepant (Nurtec ODT)
  • Ubrogepant (Ubrelvy)
  • Zavegepant (Zavzpret – nasal spray)

They are effective for patients who cannot tolerate triptans or have cardiovascular risk factors.

Anti‑Nausea Medications

Nausea and vomiting often accompany migraines. Anti‑emetics are usually added to a pain reliever.

  • Metoclopramide (Reglan)
  • Prochlorperazine (Compazine)
  • Ondansetron (Zofran)

These drugs may cause drowsiness, restlessness, or extrapyramidal symptoms; monitor for side effects.

Opioids (Rare Use)

Opioids are reserved for severe, refractory attacks, typically in a hospital setting. Evidence shows they can worsen headache frequency, lead to dependence, and reduce overall quality of life. They should be considered only after other options have failed.

Preventive Migraine Medications

Preventive therapy is aimed at reducing the number, severity, and duration of attacks. These drugs are taken regularly (often daily) and may require several weeks to show benefit.

CGRP‑Targeted Preventives

  • Monoclonal antibodies: erenumab (Aimovig), fremanezumab (Ajovy), eptinezumab (Vyepti), galcanezumab (Emgality)
  • Oral CGRP receptor antagonists: atogepant (Qulipta), rimegepant (Nurtec ODT – also approved for acute use)

Beta‑Blockers

  • Propranolol (Inderal)
  • Metoprolol (Toprol XL)

Calcium Channel Blockers

  • Verapamil (Calan, Isoptin)
  • Diltiazem (Cardizem, Tiazac)

Antidepressants

  • Amitriptyline (Elavil)
  • Venlafaxine (Effexor)

Anticonvulsants

  • Topiramate (Topamax)
  • Valproate (Depakote)

Botulinum Toxin Type A (Botox)

FDA‑approved for chronic migraine (≥15 headache days/month). Injections are given every 12 weeks and can be costly, but many patients experience a marked reduction in attack frequency.

Choosing the Right Preventive Strategy

The optimal preventive regimen depends on attack frequency, comorbid conditions, medication tolerability, and patient preference. Discuss potential side effects and the expected time to benefit with your healthcare provider.

Key Takeaways

  • Use acute medications at the first sign of a migraine; avoid using them >10 days/month to prevent rebound headaches.
  • Triptans are first‑line for moderate‑to‑severe attacks; gepants offer an alternative for those with cardiovascular risk.
  • Preventive drugs—CGRP antibodies, beta‑blockers, anticonvulsants, etc.—are recommended when attacks occur >4‑5 days per month.
  • Regular follow‑up is essential to assess efficacy, adjust dosing, and monitor side effects.
