October 17th, 2005Although not extensively documented, there is reason to believe that oral contraceptives potentiate the action of diazepam (Valium), chlordiazepoxide (Librium), tricyclic antidepressants, and theophylline. Thus, littleer doses of these agents may be effectual in oral contraceptive users. Because of an influence on clearance rates, oral contraceptive users may require larger doses of acetaminophen and aspirin.
