Drug interactions between Prilosec and tacrolimus
Interactions between your drugs
omeprazole ↔ tacrolimus
Applies to:Prilosec (omeprazole) and tacrolimus
Using omeprazole together with tacrolimus may cause a condition called hypomagnesemia, or low blood magnesium. Drugs known as proton pump inhibitors including omeprazole can cause hypomagnesemia when used for a prolonged period, and the risk may be further increased when combined with other medications that also have this effect such as tacrolimus. In severe cases, hypomagnesemia can lead to irregular heart rhythm, palpitations, muscle spasm, tremor, or seizures. Additionally, omeprazole may increase the blood levels of tacrolimus in some people. This may increase the risk of serious side effects such as diabetes, infections, kidney damage, high blood potassium (hyperkalemia), tremor, seizures, visual disturbances, high blood pressure, and heart enlargement. Your doctor may be able to prescribe alternatives that do not interact, or you may need a dose adjustment or more frequent monitoring by your doctor to safely use both medications. If you are using an over-the-counter proton pump inhibitor medication such as Prilosec OTC, Zegerid OTC or Prevacid 24 HR, you should follow the directions on the package carefully. Do not use the medication more frequently or for a longer period than recommended on the label unless otherwise prescribed by your doctor. 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.
