Drug Interactions between aliskiren / valsartan and sirolimus

Using aliskiren together with valsartan may increase the risk of serious side effects such as kidney problems, low blood pressure, and high potassium levels in the blood. High levels of potassium can develop into a condition known as hyperkalemia, which in severe cases can lead to kidney failure, muscle paralysis, irregular heart rhythm, and cardiac arrest. These medications should generally not be used together, particularly if you are diabetic or have preexisting kidney problems. Other risk factors include advanced age, dehydration, severe heart failure, or recent heart attack. Talk to you doctor if you have any questions or concerns. 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. It is important that you maintain adequate fluid intake during treatment with these medications. Ask your doctor if it is necessary for you to limit consumption of potassium-rich foods such as tomatoes, raisins, figs, potatoes, lima beans, bananas, plantains, papayas, pears, cantaloupes, mangoes, and potassium-containing salt substitutes. You should seek medical attention if you experience nausea, vomiting, weakness, confusion, tingling of the hands and feet, feelings of heaviness in the legs, a weak pulse, or a slow or irregular heartbeat, as these may be symptoms of hyperkalemia. 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.

Using valsartan together with sirolimus may increase the risk of angioedema, a condition associated with swelling of the face, eyes, lips, tongue, throat, and occasionally also the hands and feet. Although either medication alone can cause angioedema, research data suggest that the risk may be greater when they are combined. Angioedema can occur with the first dose of medication or after many doses. You should discontinue the medications and seek immediate medical attention if you develop symptoms of angioedema or have difficulty swallowing or breathing. 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.
