Beta‑Blocker Selection for Migraine Prophylaxis

First‑Line Agents with Strong Evidence

  • Propranolol (80–240 mg/day) is the most extensively studied beta‑blocker and is recommended as a first‑line preventive medication for migraine by the U.S. Headache Consortium and the American Academy of Family Physicians/ACP‑ASIM, based on multiple high‑quality trials demonstrating consistent efficacy【1】【2】【3】.
  • Timolol (20–30 mg/day) also has solid evidence supporting its use as a first‑line agent and is endorsed by the same guideline bodies【4】【5】【6】.

Second‑Line Agents (Limited Evidence)

  • Metoprolol, atenolol, and nadolol show moderate effectiveness for migraine prevention but are supported by limited evidence; they may be considered when propranolol or timolol are contraindicated or not tolerated【1】【2】【3】.

Beta‑Blockers to Avoid

  • Beta‑blockers with intrinsic sympathomimetic activity (acebutolol, alprenolol, oxprenolol, pindolol) are ineffective for migraine prophylaxis and should not be used【1】【2】【3】.

Choosing Between Propranolol and Timolol

  • Propranolol is superior in patients with migraine alone (without co‑existing tension‑type headache)【4】【1】【2】.
  • When migraine co‑exists with tension‑type headache, amitriptyline is suggested as an alternative【4】【5】.

Dosing Strategy and Trial Duration

  • Initiate therapy at a low dose and titrate slowly, increasing until clinical benefit appears or adverse effects limit further escalation【4】【5】.
  • Allow an adequate trial period of 2–3 months, as therapeutic effects may not become evident earlier【4】【5】.

Safety and Tolerability

  • Common adverse effects include fatigue, depression, nausea, dizziness, and insomnia; these are generally well tolerated and rarely lead to premature discontinuation【4】【1】【2】.
  • Contraindications: avoid beta‑blockers in patients with asthma, severe bradycardia, heart block, or uncontrolled heart failure【6】.

Position Relative to Newer Therapies

  • CGRP‑targeted monoclonal antibodies (erenumab, fremanezumab, galcanezumab) have strong evidence for episodic and chronic migraine prevention【7】.
  • Despite newer agents, propranolol and timolol remain first‑line options because of their established efficacy, favorable safety profile, and cost‑effectiveness【4】【6】.

Guideline Endorsements

  • The 2025 American College of Physicians (ACP) guidelines continue to endorse beta‑blockers as appropriate first‑line preventive therapy for migraine【8】.
