DRUG INTERACTIONS: Carbamazepine interacts with multiple drugs, and caution should be used in combining other medicines with it. Lower levels of carbamazepine are seen when administrated with phenobarbital, phenytoin (Dilantin), or primidone (Mysoline). Warfarin (Coumadin), phenytoin (Dilantin), theophylline, and valproic acid (Depakote, Depakote ER, Depakene, Depacon) are more rapidly eliminated with carbamazepine, while carbamazepine levels are elevated when taken with erythromycin, cimetidine (Tagamet), propoxyphene (Darvon), and calcium channel blockers. Carbamazepine also increases the elimination of the hormones in birth control pills and can reduce the effectiveness of birth control pills. Unexpected pregnancies have occurred in patients taking both carbamazepine and birth control pills.
