    Minor interaction

    Severity: Minor

    Severity basis: drug interactions section. Combining Itraconazole (Azole antifungal (strong CYP3A4 inhibitor)) and Pantoprazole (Proton pump inhibitor) is classified as a minor interaction.

    What to Do

    This is generally a minor interaction, but review it with your pharmacist to be sure it is safe for you.

    How This Interaction Works

    Interactions like this one can happen when two medicines have overlapping effects, or when one changes how the other is absorbed, broken down, or cleared from the body. Itraconazole is a azole antifungal (strong cyp3a4 inhibitor) and Pantoprazole is a proton pump inhibitor; together they are documented as a minor interaction. How much this matters depends on your dose, your other medications, and your overall health.

    If You Take Both Medications

    If you have been prescribed both Itraconazole and Pantoprazole, do not start, stop, or change either medication on your own — some medicines are unsafe to stop suddenly. Tell your prescriber and pharmacist that you take both so they can decide whether the combination is right for you, adjust the dose, monitor you more closely, or suggest an alternative.
