Drug Interactions between Juxtapid and Yaz

Talk to your doctor before using lomitapide together with ethinyl estradiol. Combining these medications may significantly increase the blood levels and effects of lomitapide. You may be more likely to experience side effects such as diarrhea, nausea, vomiting, stomach pain or discomfort, indigestion, gas, constipation, and liver damage. At the same time, the absorption of ethinyl estradiol may be affected if you develop diarrhea or vomiting, which may reduce its effectiveness in preventing pregnancy. 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. Avoid or limit the use of alcohol during treatment with lomitapide, and seek immediate medical attention if you develop signs and symptoms of liver damage such as fever, chills, joint pain or swelling, unusual bleeding or bruising, skin rash, itching, loss of appetite, fatigue, nausea, vomiting, dark colored urine, light colored stools, and yellowing of the skin or eyes. 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.

Lomitapide may increase the blood levels of drospirenone in some patients. This can increase the risk of developing hyperkalemia, or high levels of potassium in the blood, which in severe cases can lead to kidney failure, muscle paralysis, irregular heart rhythm, and cardiac arrest. Hyperkalemia is usually more likely to occur in people who are 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), or prescription medications such as potassium supplements or certain medications used to treat high blood pressure or heart conditions, may also increase the risk. Talk to your 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 to safely use both medications. You should seek medical attention if you experience nausea, vomiting, weakness, confusion, tingling of the hands and feet, a weak pulse, or a slow or irregular heartbeat, as these may be symptoms of hyperkalemia.
