Aspirin and acetaminophen are also available by prescription in combination with a short-acting barbiturate (butalbital). No randomized, placebo-controlled studies support the efficacy of butalbital-containing formulations for migraine. [Pg.618]

High-dose NSAIDs and the combination of aspirin or acetaminophen with butalbital or, rarely, codeine, are effective options. The use of butalbital and codeine combinations should be avoided when possible. [Pg.625]
