Topical antihistamines, such as diphenhydramine creams, sprays or ointments, may interact with meclizine, warns WebMD. Before taking meclizine, the individual should tell her doctor if she takes other medications that may cause drowsiness, such as other antihistamines, drugs that treat anxiety or promote sleep, muscle relaxants, and narcotic pain relievers, because combining these medications with meclizine can intensify the drowsiness. This drowsiness also means that driving and operating heavy machinery while taking it are contraindicated, notes RxList. Individuals should not drink alcohol while taking meclizine.
