Study Notes
Migraine Prophylaxis and Rescue Therapy in Special Populations
- Pregnancy: Increased risk of pre-eclampsia and gestational hypertension. Acetaminophen, magnesium IV, NSAIDs (1st and 2nd trimester only), Metoclopramide IV, and certain triptans can be considered.
- Pediatrics: Devices are an option for children aged 12 and above. Acetaminophen, NSAIDs (ibuprofen, naproxen), and certain triptans can be used for children over 6 years old.
- CAD: Avoid triptans, ergot alkaloids, and potential drug-drug interactions with NSAIDs (anticoagulants, antiplatelets).
- CHF: Avoid NSAIDs and corticosteroids.
- PUD: Avoid NSAIDs and corticosteroids.
- Geriatrics: Avoid NSAIDs and ditans.
- CKD: Avoid NSAIDs and Rimegepant (CrCl < 15). Naratriptan requires dose adjustment and should be avoided in CrCl < 15.
- Liver Disease: Avoid NSAIDs, ditans, gepants, and certain triptans. Reduce the maximum daily dose of acetaminophen.
- Sulfa allergy: Avoid almotriptan.
- Serotonergic Agents: Avoid use with triptans and ditans due to potential interactions.
- QTc prolongation: Be cautious with medications that prolong QTc.
- Antiemetics: Consider CYP3A4 interactions with gepants, almotriptan, eletriptan, and ergot alkaloids. Use non-oral medications for nausea and vomiting.
Migraine Prophylaxis Considerations:
- Goals of therapy: Prevent headaches, improve quality of life, reduce severity and frequency, educate patients, and reduce headache-related distress.
- Indications for Migraine Prophylaxis: Patient preference, acute migraines that interfere with daily routines despite treatment, frequent attacks, overuse of acute treatments, headaches that reoccur in a predictable pattern, and uncommon migraine variants.
- Treatment timeline: Start with a low dose and titrate up. Some benefit may be seen after 1 month, but therapeutic trials must be 2-6 months long. Prophylaxis is continued for at least 6-12 months after headache frequency is diminished.
- FDA Approved Therapies for Prophylaxis: Propranolol, timolol, non-DHP CCBs, valproic acid, divalproex sodium, topiramate, amitriptyline, nortriptyline, venlafaxine, frovatriptan, naratriptan, zolmitriptan, rimegepant, atogepant, anti-CGRP antibodies (erenumab, fremanezumab, galcanez
