Applies to: rifabutin and Fotivda (tivozanib)

Rifabutin may significantly reduce the blood levels of tivozanib, which may make the medication less effective in treating your condition.

You should seek immediate medical attention if you experience sudden dizziness, lightheadedness, fainting, shortness of breath, or heart palpitations during treatment with these medications, whether together or alone. Talk to your doctor if you have any questions or concerns. Your doctor may already be aware of the interaction, but has determined that this is the best course of treatment for you and has taken appropriate precautions or made dose adjustments and is monitoring you closely for any potential complications. Your doctor may also be able to prescribe alternatives that do not interact. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
