DRUG INTERACTIONS: Blood levels of apixaban are increased by drugs that reduce the activity of the liver enzymes that break down apixaban. The dose of apixaban should be reduced to 2.5 mg twice daily if combined with drugs that reduce the activity of these enzymes. Examples include ketoconazole (Nizoral, Extina, Xolegel, Kuric), itraconazole (Sporanox), ritonavir (Norvir), and clarithromycin (Biaxin, Biaxin XL).

Drugs that increase the breakdown of apixaban reduce its blood levels and its effectiveness. Examples include carbamazepine (Tegretol, Tegretol XR, Equetro, Carbatrol), rifampin, St. John's Wort, and phenytoin (Dilantin, Dilantin-125. They should not be combined with apixaban.
