Mycophenolate Mofetil/Proton Pump Inhibitors Interactions
This information is generalized and not intended as specific medical advice. Consult your healthcare professional before taking or discontinuing any drug or commencing any course of treatment.
Medical warning:
Moderate. These medicines may cause some risk when taken together. Contact your healthcare professional (e.g. doctor or pharmacist) for more information.
How the interaction occurs:
Your heartburn/ulcer medicine may decrease the amount of mycophenolate absorbed into your body.
What might happen:
The amount of mycophenolic acid, the active form of your medicine, in your blood may decrease. This may increase your risk of organ rejection and other side effects.
What you should do about this interaction:
Make sure your healthcare professionals (e.g. doctor or pharmacist) know that you are taking these medicines together. Your doctor may want to check the amount of medicine in your blood and/or change the dose of your medicine.Your healthcare professionals may already be aware of this interaction and may be monitoring you for it. Do not start, stop, or change the dosage of any medicine before checking with them first.
