Drug Interactions
The effects of some drugs can change if you take other drugs or herbal products at the same time. This can increase your risk for serious side effects or may cause your medications not to work correctly. These drug interactions are possible, but do not always occur. Your doctor or pharmacist can often prevent or manage interactions by changing how you use your medications or by close monitoring. To help your doctor and pharmacist give you the best care, be sure to tell your doctor and pharmacist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products) before starting treatment with this product. While using this product, do not start, stop, or change the dosage of any other medicines you are using without your doctor's approval. Some products that may interact with this drug include: amiodarone, atazanavir, certain benzodiazepines (alprazolam, midazolam, triazolam), conivaptan, eletriptan, ergot alkaloids (such as dihydroergotamine, ergonovine, ergotamine, methylergonovine), pimozide, ranolazine, rifampin, certain "statin" cholesterol drugs (lovastatin, rosuvastatin, simvastatin), St. John's wort. Other medications can affect the removal of indinavir from your body, which may affect how indinavir works.

Indinavir can slow down the removal of other medications from your body, which may affect how they work. Examples of affected drugs include trazodone, certain calcium channel blockers (such as nifedipine, felodipine, nicardipine), certain drugs that weaken the immune system (cyclosporine, tacrolimus, sirolimus), drugs to treat erectile dysfunction/pulmonary hypertension (such as sildenafil, vardenafil), among others.
