DRUG INTERACTIONS: Infrequently, a very serious, life-threatening decrease in the amount of blood supply to the hands and feet (peripheral ischemia) and rarely to the brain can occur when this medication is taken with drugs that affect liver metabolism (e.g., potent CYP 3A4 enzyme inhibitors). Do not take this medication with macrolide antibiotics (e.g., erythromycin, clarithromycin, troleandomycin), protease inhibitors (e.g., ritonavir, nelfinavir, indinavir, amprenavir, saquinavir), azole antifungals (e.g., ketoconazole, itraconazole).

Tell your doctor if you take any drugs that make you drowsy, such as: sedatives, tranquilizers, narcotic pain relievers (e.g., codeine), muscle relaxants, certain antihistamines (e.g., diphenhydramine). Avoid eating grapefruit or drinking grapefruit juice while using this medication unless your doctor instructs you otherwise. Avoid drinking caffeine-containing beverages (coffee, tea, colas) and eating large amounts of chocolate. Because this medication contains caffeine, the risk of side effects may be increased.
