Protonix 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 your doctor or pharmacist first.

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

• atazanavir
• nelfinavir

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

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

• warfarin

Some other drugs need stomach acid so that the body can absorb them properly. Pantoprazole decreases stomach acid, so it may keep these other drugs from working well. Before using pantoprazole, consult your doctor or pharmacist about how to take it while also being treated with any of the following drugs:

• ampicillin
• azole antifungals (e.g., ketoconazole, itraconazole)
• iron supplements

This medication may affect the results of certain lab tests (e.g., urine test for tetrahydrocannabinol-THC). Make sure laboratory personnel and your doctors know you use this drug.

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.
