Drug Interactions between ivabradine and lomitapide

Do not consume grapefruit or grapefruit juice during treatment with ivabradine. Grapefruit juice can significantly increase the blood levels and effects of ivabradine, which may result in excessive slowing of heart rate or other conduction disturbances. Talk to your doctor if you have any questions or concerns. Let your doctor know if you experience significant decreases in heart rate or symptoms such as dizziness, fatigue, or low blood pressure. Also seek medical attention if you develop heart palpitations, chest pressure, or worsened shortness of breath, as these may be symptoms of atrial fibrillation caused by ivabradine. 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.

Taking lomitapide with food may increase gastrointestinal side effects such as diarrhea, nausea, vomiting, stomach pain or discomfort, constipation, indigestion, and gas. The absorption of any other oral medication you may take can be affected if you develop diarrhea or vomiting. To reduce the risk of gastrointestinal intolerance, lomitapide should be taken once daily with a glass of water, without food, at least 2 hours after the evening meal. You should also follow a low-fat diet (<20% of total calories from fat) during treatment with lomitapide, and avoid the consumption of grapefruit or grapefruit juice. Since lomitapide may cause injury to the liver, you should have no more than one alcoholic drink per day. Call your doctor immediately if you have fever, chills, joint pain or swelling, unusual bleeding or bruising, skin rash, itching, loss of appetite, fatigue, nausea, vomiting, abdominal pain, dark colored urine, light colored stools, and/or yellowing of the skin or eyes, as these may be signs and symptoms of liver damage.
