Prilosec Oral Interactions

Your doctor or pharmacist may already be aware of any possible drug interactions and may be monitoring you for them. Do not start, stop, or change the dosage of any medicine before checking with them first.

This drug should not be used with the following medications because very serious interactions may occur:

• atazanavir
• nelfinavir

If you are currently using any of these medications, tell your doctor or pharmacist before starting omeprazole.

Before using this medication, tell your doctor or pharmacist of all prescription and nonprescription/herbal products you may use, especially of:

• certain drugs to suppress the immune system (e.g., cyclosporine, tacrolimus)
• cilostazol
• diazepam
• disulfiram
• phenytoin
• tipranavir
• voriconazole
• warfarin

Some products need stomach acid so that the body can absorb them properly (such as ampicillin, iron supplements, calcium supplements, dasatinib, azole antifungals including ketoconazole). Omeprazole decreases stomach acid, so it may change how well these other products work. Before using omeprazole, consult your doctor or pharmacist about the other medications you take and for advice on how to reduce or avoid these types of interactions.

Based on information for similar drugs, omeprazole may increase the amount of digoxin that is absorbed into your blood. Consult your doctor or pharmacist for details if you also take digoxin.

This document does not contain all possible interactions. Therefore, before using this product, tell your doctor or pharmacist of all the products you use. Keep a list of all your medications with you, and share the list with your doctor and pharmacist.
