Cimetidine (Tagamet), ketoconazole (Nizoral), itraconazole (Sporanox), omeprazole (Prilosec, Rapinex), erythromycin, clarithromycin (Biaxin), darunavir (Prezista), ( (fluvoxamine (Luvox), and fluoxetine (Prozac) may prolong the effects of diazepam by inhibiting liver enzymes that eliminate diazepam. Dosages may need to be decreased when these drugs are used with diazepam.

Carbamazepine (Tegretol), rifampin (Rifadin), and St. John's Wort decrease levels of diazepam by increasing the elimination of diazepam by liver enzymes.

PREGNANCY: Benzodiazepines, including diazepam, can cause fetal abnormalities and should not be used during pregnancy.

NURSING MOTHERS: Diazepam is excreted in breast milk and can affect nursing infants. Therefore, diazepam should not be used by women who are nursing.
