Drug Interactions between aliskiren / valsartan and ponatinib

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.

PONATinib may increase the blood levels of aliskiren in some patients. You may need a dose adjustment or more frequent monitoring by your doctor to safely use both medications. High blood levels of aliskiren can cause an excessive fall in blood pressure and increase the risk of developing a condition known as hyperkalemia, or high blood potassium. In severe cases, hyperkalemia can lead to kidney failure, muscle paralysis, irregular heart rhythm, and cardiac arrest. You may be more likely to develop hyperkalemia while taking aliskiren if you are elderly, dehydrated, or have kidney disease, diabetes, or advanced heart failure. Regular or long-term use of nonsteroidal anti-inflammatory drugs such as ibuprofen or naproxen (Aleve) may also increase your risk. It is important that you maintain adequate fluid intake during treatment with aliskiren.
