Mipomersen Side Effects and Adverse Reactions
Like all medications, Mipomersen can cause side effects. It is important to be aware of potential reactions and to contact your healthcare provider if you experience any concerning symptoms. Below are some of the most common and serious side effects:
Common Side Effects
Injection Site Reactions: Redness, pain, or swelling at the injection site. These reactions are common but usually mild.
Flu-like Symptoms: Some patients may experience fatigue, fever, or muscle aches after the injection.
Nausea: Nausea is a common side effect, especially during the first few weeks of treatment.
Serious Side Effects
Liver Problems: Mipomersen can cause liver damage, which may be detected through blood tests. Symptoms of liver issues include yellowing of the skin or eyes, dark urine, and abdominal pain.

If you experience any of these side effects, contact your healthcare provider immediately. Our telemedicine providers are available to help you manage your symptoms and adjust your treatment plan if necessary.
Contraindications for Mipomersen
A contraindication is a specific situation or condition where a particular medication should not be used because it may cause harm to the patient. If you have any of the conditions listed below, Mipomersen may not be safe for you. Always consult with one of our healthcare providers through telemedicine before starting or stopping any medication.
Liver Disease: Mipomersen is contraindicated in patients with active liver disease or persistent, unexplained elevations in liver enzymes. This is because Mipomersen can increase liver enzyme levels and worsen liver function, potentially leading to serious liver damage.
Allergic Reactions: If you have had an allergic reaction to Mipomersen or any of its ingredients, you should not take this medication. Allergic reactions can range from mild rashes to severe, life-threatening conditions like anaphylaxis.
Moderate to Severe Kidney Disease: Mipomersen is not recommended for patients with moderate to severe kidney impairment, as it may exacerbate kidney function issues.
Drug to Drug Interactions
It’s important to inform your healthcare provider about all the medications you are currently taking, including prescription drugs, over-the-counter products, and herbal supplements. Some medications may interact with Mipomersen, a cholesterol-lowering drug, potentially leading to harmful side effects or reducing its effectiveness. Below are some known drug interactions:
Statins: Medications such as atorvastatin (Lipitor) and simvastatin (Zocor) may increase the risk of liver damage when used alongside Mipomersen.
Anticoagulants: Blood thinners like warfarin (Coumadin) may interact with Mipomersen, increasing the risk of bleeding.
Other Cholesterol-Lowering Medications: Drugs like ezetimibe (Zetia) may have additive effects when combined with Mipomersen, potentially heightening the risk of side effects, including liver toxicity.
Mipomersen in Pregnancy
Is it safe to take Mipomersen during pregnancy? The safety of Mipomersen in pregnant women has not been well established. Animal studies suggest potential risks to the fetus, and there is limited data on its use in humans. If you are pregnant or planning to become pregnant, it’s essential to discuss the potential risks and benefits of this cholesterol-lowering medication with your healthcare provider. You can also schedule a telemedicine appointment with one of our providers for personalized advice.
Mipomersen while Breastfeeding
Is it safe to take Mipomersen while breastfeeding? It is unclear whether Mipomersen passes into breast milk. Due to the potential for serious adverse effects in nursing infants, it is generally recommended to avoid Mipomersen while breastfeeding. Consult your healthcare provider to carefully weigh the risks and benefits and explore alternative lipid-lowering therapies if needed.
Estimated Cost of Mipomersen
The estimated cost of a 30-day supply of Mipomersen without insurance ranges from approximately $5,000 to $6,000. Using a GoodRx coupon may slightly reduce the price, though the cost remains high. Be sure to check with your pharmacy for the most accurate pricing, and explore any available patient assistance programs for this treatment for familial hypercholesterolemia.
Possible Alternatives to Mipomersen
If Mipomersen is not suitable for you, there are alternative treatments and lifestyle changes that may help manage your condition. Always consult your healthcare provider before making any changes to your treatment plan. Our telemedicine providers are available to discuss these options with you.
Homozygous Familial Hypercholesterolemia: Alternatives include other cholesterol-lowering medications such as lomitapide (Juxtapid) or PCSK9 inhibitors like alirocumab (Praluent) and evolocumab (Repatha). Lifestyle changes, including a low-fat, low-cholesterol diet and regular exercise, are also recommended.
Hyperlipidemia: Statins (e.g., atorvastatin, rosuvastatin) are commonly prescribed to lower cholesterol levels. Dietary changes, such as increasing fiber intake and reducing saturated fats, can also help manage hyperlipidemia.
Atherosclerosis: Medications like aspirin, statins, and blood pressure medications can help manage atherosclerosis. Quitting smoking, eating a heart-healthy diet, and engaging in regular physical activity are key lifestyle changes.
Cardiovascular Disease: Treatment options include statins, beta-blockers, and ACE inhibitors. Lifestyle changes such as maintaining a healthy weight, exercising regularly, and reducing salt intake are crucial for managing cardiovascular disease.
Coronary Artery Disease: Statins, antiplatelet drugs (e.g., aspirin), and beta-blockers are often prescribed. Lifestyle changes like quitting smoking, eating a balanced diet, and exercising regularly can also help manage the condition.
Dyslipidemia: Statins, fibrates, and niacin are commonly used to treat dyslipidemia. Dietary modifications and regular physical activity are also important components of treatment.
High Cholesterol: Statins are the first-line treatment for high cholesterol. Dietary changes, such as reducing trans fats and increasing omega-3 fatty acids, can also help lower cholesterol levels.
Familial Hypercholesterolemia: PCSK9 inhibitors, statins, and ezetimibe are often prescribed. Genetic counseling and lifestyle changes, such as following a heart-healthy diet and engaging in regular exercise, are also recommended.
Peripheral Artery Disease: Medications like cilostazol (Pletal) and aspirin are often used. Quitting smoking, managing blood sugar levels, and regular exercise can help improve symptoms.
Stroke: Antiplatelet drugs (e.g., aspirin, clopidogrel) and anticoagulants are used to prevent future strokes. Lifestyle changes like controlling blood pressure, quitting smoking, and eating a healthy diet are essential for stroke prevention.
Recent Updates on Mipomersen Research
Recent studies on Mipomersen have focused on its long-term safety and effectiveness in lowering LDL cholesterol levels in patients with homozygous familial hypercholesterolemia. While Mipomersen has been shown to reduce cholesterol, it can cause significant side effects, particularly related to liver function. Ongoing research aims to minimize these side effects while maintaining the drug’s efficacy. If you’re interested in learning more about the latest research or participating in clinical trials, consult one of our healthcare providers through telemedicine.
