Do butalbital-containing products have a role in the management of migraine?

Study Objective. To evaluate the role of butalbital-containing products in the management of migraine, Methods. Qualitative systematic search using MEDLINE (January 1966-November 2001), review of the United States Headache Consortium's evidence-based guidelines for migraine treatment, and review of other pertinent literature. Results. Over 28 million people suffer with migraine, yet this illness is less than optimally diagnosed and managed. Between 14% and 36% of diagnosed migraineurs are prescribed butalbital-containing products, often as initial therapy. However, the only identified controlled trial of these drugs for migraine treatment showed that butalbital-containing products were inferior to butorphanol. The consortium's guidelines specifically discourage administration of butalbital-containing products for migraine. in addition, other published literature highlights the frequent adverse consequences of butalbital-containing products for migraineurs, such as poor migraine control, disability, drug-induced headaches, and withdrawal symptoms. Conclusion. Although butalbital-containing products commonly are prescribed for migraine, no evidence in the literature demonstrates their benefit over other agents or placebo. Drugs With proven migraine efficacy, as listed in the consortium's evidence-based guidelines, should be prescribed instead.
