DATA SOURCES We searched MEDLINE via PubMed for guidelines on migraine management published since 1990 in any language; in addition, we browsed the Internet for information. STUDY SELECTION We found nine clinical guidelines on migraine; one guideline, not supported by references, was excluded. SYNTHESIS Preference for triptans is not well founded and is largely based on comparisons with placebo. Too few studies compared new drugs with established ones (NSAIDs or dihydroergotamine). Guidelines that propose a hierarchy for selection of drugs are opinion-based rather than evidence-based. CONCLUSION The current lack of evidence from comparative studies seriously limits development of evidence-based clinical practice guidelines for pharmacologic treatment of migraine. ER -
