US PharmacistPharmacist Involvement in OTC Migraine Management

Migraines affect 39 million Americans with significant disability impact, yet pharmacists remain underutilized in comprehensive migraine management. This educational review addresses pharmacist-led interventions spanning acute treatment selection, preventive therapy optimization, and medication overuse headache recognition. Evidence supports expanded pharmacist roles in trigger identification, supplement counseling, and patient triage, with direct implications for improving treatment adherence and reducing emergency department utilization.

⚕️ Key Clinical Considerations ⚕️

• Acute treatment stratification requires individualized selection based on migraine severity (NSAIDs for mild-moderate attacks, triptans for moderate-severe), onset patterns, and cardiovascular contraindications, with triptan vasoconstrictive effects contraindicating use in uncontrolled hypertension or coronary artery disease.
• Preventive therapy initiation thresholds include four or more attacks monthly, eight or more headache days monthly, or significant quality-of-life impact, with treatment effectiveness defined as 50% frequency reduction over 3 months using agents like topiramate, propranolol, or CGRP monoclonal antibodies.
• Medication overuse headache diagnostic criteria require headaches 15+ days monthly with 3+ months of overuse, more commonly precipitated by single-analgesic agents (NSAIDs, acetaminophen) than triptans, generally resolving upon medication cessation with pharmacist intervention essential for early recognition.
• Supplement evidence base demonstrates vitamin B2 (400 mg/day for 3 months) significantly reduces migraine duration, frequency, and pain scores in meta-analysis of eight randomized controlled trials, while ginger, butterbur, and feverfew show symptom improvement requiring drug interaction screening.
• Trigger identification through headache diary implementation reveals stress, meal habits, sleep factors, and hormonal fluctuations as primary triggers, with common dietary triggers (caffeine, citrus, chocolate, dairy, alcohol) lacking robust randomiz

🎯 Clinical Practice Impact 🎯

• Patient Communication: Redirect 90% self-diagnosing “sinus headaches” to migraine-specific therapy. Recommend MIDAS self-assessment with physician referral for scores ≥6.
• Practice Integration: Implement headache diaries to identify triggers. Screen for medication overuse in patients using analgesics twice-weekly or more frequently.
• Risk Management: Contraindicate triptans in uncontrolled hypertension and coronary disease. Screen supplement-drug interactions for vitamin B2, butterbur, feverfew, and ginger.
• Pharmacist Triage: Apply ICHD-3 criteria requiring five attacks with two features (unilateral, pulsatile, moderate-to-severe pain, activity aggravation) plus nausea or sensory sensitivity for migraine diagnosis versus other headache types.
