Migraine Prevention with Beta-Blockers
Recommended Beta-Blockers and Dosing
- The American Academy of Family Physicians recommends propranolol (80-240 mg/day) and timolol (20-30 mg/day) as first-line agents for migraine prevention, with the strongest evidence for efficacy 1, 2
- Beta-blockers without intrinsic sympathomimetic activity (ISA) are considered effective for migraine prevention 1
- The American Family Physician suggests that amitriptyline (30-150 mg/day) is also a first-line option for migraine prevention 1, 2
Patient Selection and Efficacy
- Patients with two or more migraine attacks per month with disability lasting 3+ days per month may benefit from beta-blockers 2
- Patients using acute rescue medications more than twice per week may also benefit from beta-blockers 2
- The American Family Physician recommends considering beta-blockers for patients with failure of or contraindications to acute migraine treatments 2
Side Effects and Monitoring
- Common adverse effects of beta-blockers include fatigue, depression, nausea, dizziness, and insomnia, which are generally well-tolerated 1, 2
- Monitoring for mood changes, particularly depression, sleep disturbances, and bradycardia or heart block (contraindications) is recommended 2
Alternative First-Line Options
- The American Family Physician recommends divalproex sodium (500-1,500 mg/day) and sodium valproate (800-1,500 mg/day) as alternative first-line options for migraine prevention 1
- Candesartan or telmisartan (ARBs) are strongly recommended by newer guidelines for migraine prevention 3
- CGRP monoclonal antibodies (erenumab, fremanezumab, galcanezumab) are strongly recommended for both episodic and chronic migraine, while topiramate has a weak recommendation 3
