Adverse Reactions and Lomitapide Side Effects

Like all medications, Lomitapide may cause side effects. Some are more common, while others are less frequent but potentially more serious. If you experience any side effects, contact your healthcare provider right away. You can also schedule a telemedicine visit with one of our providers for further evaluation.

Common Side Effects

1. Diarrhea: Loose or watery stools, often occurring shortly after taking the medication.
2. Nausea: A feeling of discomfort or unease in the stomach.
3. Vomiting: The forceful expulsion of stomach contents through the mouth.
4. Abdominal Pain: Discomfort or pain in the stomach area.

Serious Side Effects

1. Liver Damage: Lomitapide can cause liver problems, including elevated liver enzymes. Symptoms may include yellowing of the skin or eyes (jaundice), dark urine, or pain in the upper right abdomen.
2. Fat-Soluble Vitamin Deficiency: Lomitapide can reduce the absorption of vitamins A, D, E, and K, which are essential for maintaining overall health.

Contraindications

A contraindication is a specific condition or situation where a medication should not be used because it may cause harm. It’s important to be aware of any contraindications before starting Lomitapide.

Lomitapide is contraindicated in the following situations:

1. Pregnancy: Lomitapide can harm an unborn baby. It is classified as a Category X drug, meaning it should not be used during pregnancy due to the risk of birth defects.
2. Moderate to severe liver disease: Lomitapide can increase liver enzymes and cause liver damage. If you already have liver disease, taking Lomitapide could worsen your condition.
3. Use of strong CYP3A4 inhibitors: Medications that strongly inhibit the CYP3A4 enzyme (such as certain antifungals and antibiotics) can increase Lomitapide levels in your body, leading to serious side effects like liver damage.
4. Allergy to Lomitapide or any of its ingredients: If you have a known allergy to Lomitapide or any of its inactive ingredients, you should not take it.

Drug-to-Drug Interactions

Lomitapide can interact with other medications, increasing the risk of side effects or reducing the effectiveness of either drug. It’s important to inform your healthcare provider of all medications you are taking, including over-the-counter drugs and supplements.

Some medications that may interact with Lomitapide include:

1. Ketoconazole (Nizoral): A strong CYP3A4 inhibitor that can increase Lomitapide levels, potentially leading to liver damage.
2. Itraconazole (Sporanox): Another antifungal that inhibits CYP3A4 and can increase the risk of Lomitapide-related side effects.
3. Clarithromycin (Biaxin): An antibiotic that can raise Lomitapide levels in the blood, increasing the risk of liver issues.
4. Atorvastatin (Lipitor): A cholesterol-lowering medication that can heighten the risk of liver damage when taken with Lomitapide.
5. Simvastatin (Zocor): Another statin that can increase the risk of muscle problems and liver damage when used with Lomitapide.
6. Warfarin (Coumadin): Lomitapide can enhance the effects of warfarin, raising the risk of bleeding.

Lomitapide in Pregnancy

Is it Safe to Take Lomitapide During Pregnancy?

No, Lomitapide is not safe to use during pregnancy. It is classified as a Category X medication, meaning it poses a significant risk of causing harm to an unborn baby, including birth defects. Women of childbearing age should use reliable contraception while taking Lomitapide and discontinue the medication immediately if they become pregnant. If you are pregnant or planning to become pregnant, it is important to consult with one of our healthcare providers through telemedicine to discuss safer alternatives for managing cholesterol levels.

Lomitapide While Breastfeeding

Is it Safe to Take Lomitapide While Breastfeeding?

No, Lomitapide is not recommended for use while breastfeeding. It is unclear whether Lomitapide passes into breast milk, but due to the potential for serious side effects in a nursing infant, breastfeeding mothers should avoid this medication. If you are breastfeeding, speak with one of our providers to explore safer options for managing cholesterol levels.

Estimated Cost of Lomitapide

The estimated cost of a 30-day supply of Lomitapide (5 mg) without insurance ranges from approximately $26,000 to $27,000. However, using a GoodRx coupon may reduce the price to around $24,000. Prices can vary depending on the pharmacy and location, so it’s advisable to check for discounts and speak with your healthcare provider about financial assistance programs if needed. The cost of Lomitapide can be a significant factor in treatment decisions, so it’s essential to explore all available options.

Possible Alternatives to Lomitapide

There are several alternative treatments and lifestyle changes that may help manage the conditions Lomitapide is prescribed for. Always discuss these options with your healthcare provider before making any changes to your treatment plan. You can also schedule a telemedicine appointment with one of our providers to explore these alternatives.

Homozygous Familial Hypercholesterolemia (HoFH)

Other medications, such as statins (e.g., atorvastatin, rosuvastatin) or PCSK9 inhibitors (e.g., evolocumab, alirocumab), may be considered. In addition, lifestyle changes, including a low-fat, heart-healthy diet and regular exercise, can help manage cholesterol levels in patients with HoFH.

Hyperlipidemia

Statins, fibrates, and niacin are common alternatives to Lomitapide for treating hyperlipidemia. Dietary changes, such as reducing saturated fats and increasing fiber intake, can also improve lipid profiles and support cholesterol management.

Atherosclerosis

Medications like statins, aspirin, and blood pressure medications may be used to slow the progression of atherosclerosis. Quitting smoking, eating a heart-healthy diet, and exercising regularly are crucial lifestyle changes that can complement medication therapy.

Coronary Artery Disease

Medications such as beta-blockers, ACE inhibitors, and statins can help manage coronary artery disease. Lifestyle changes, including weight loss, smoking cessation, and stress management, are also important for improving heart health.

Peripheral Artery Disease

Medications like cilostazol and statins can help improve symptoms of peripheral artery disease. Exercise, particularly walking, is a key part of managing this condition and improving circulation.

Stroke

Blood thinners, statins, and blood pressure medications are often used to reduce the risk of stroke. Lifestyle changes, such as reducing salt intake, quitting smoking, and controlling blood sugar levels, are also important for stroke prevention.

Heart Attack

After a heart attack, medications like beta-blockers, ACE inhibitors, and statins are commonly prescribed. Cardiac rehabilitation and lifestyle changes, such as a heart-healthy diet and regular exercise, are essential for recovery and preventing future heart events.

Dyslipidemia

Statins, fibrates, and omega-3 fatty acids are common treatments for dyslipidemia. Dietary changes, such as reducing trans fats and increasing fiber, can also help manage dyslipidemia and improve overall cholesterol levels.

Metabolic Syndrome

Lifestyle changes, including weight loss, increased physical activity, and a healthy diet, are the first line of treatment for metabolic syndrome. Depending on individual risk factors and cholesterol levels, medications like metformin or statins may be prescribed.

Type 2 Diabetes Mellitus

Medications such as metformin, insulin, or SGLT2 inhibitors may be used to manage blood sugar levels in patients with Type 2 diabetes. A balanced diet, regular exercise, and weight management are key components of managing Type 2 diabetes and reducing cardiovascular risk.

Recent Updates on Lomitapide Research

Recent research on Lomitapide has focused on its long-term safety and effectiveness in treating homozygous familial hypercholesterolemia (HoFH). Studies show that Lomitapide can significantly reduce LDL cholesterol levels in HoFH patients, but ongoing liver function monitoring is crucial due to the risk of liver damage. Researchers are also exploring the potential for Lomitapide to be used in combination with other cholesterol-lowering therapies, such as PCSK9 inhibitors, to improve outcomes for patients with severe hypercholesterolemia. As new studies are published, it’s important to stay informed and discuss any updates with your healthcare provider to ensure the best treatment plan for managing cholesterol levels.
