Drug interactions between ritonavir and tacrolimus
Interactions between your drugs
Applies to: tacrolimus and ritonavir
Using tacrolimus together with ritonavir is not recommended. Combining these medications can significantly increase the blood levels of tacrolimus, which may make you more likely to develop serious side effects. 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. Talk to your doctor if you have any questions or concerns. You should seek medical attention if you experience side effects such as fever, rash, headache, tremor, nausea and vomiting, increased blood sugar, cholesterol, or triglyceride concentrations, numbness or tingling in your hands and feet, unusual bleeding or bruising, high blood pressure, palpitations, burning sensation on urination or increased urgency to urinate, yellowing of the skin, symptoms of anemia such as shortness of breath, tiredness or dizziness, swelling of the feet or legs, muscle aches, pneumonitis (inflammation of the lungs), new lumps or moles, or changes to existing moles anywhere on the body. 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.

If you are already consuming grapefruit products, do not increase or decrease the amount of these products in your diet without first talking to your doctor.
