(lomitapide)

How does this medication work? What will it do for me?

Lomitapide belongs to the class of medications called triglyceride transfer protein inhibitors. It is used, in addition to a low-fat diet and other lipid lowering medications, to reduce the amount of LDL cholesterol ("bad" cholesterol) in the blood, for adults who have a genetic condition called homozygous familial hypercholesterolemia (HoFH) that causes the body to produce too much LDL cholesterol.

In the liver and gut cells, fatty substances are built into larger fat particles that are then released into the blood stream. Lomitapide works by blocking the production of these larger particles, reducing the amount of cholesterol in the blood.

This medication may be available under multiple brand names and/or in several different forms. Any specific brand name of this medication may not be available in all of the forms or approved for all of the conditions discussed here. As well, some forms of this medication may not be used for all of the conditions discussed here.

Your doctor may have suggested this medication for conditions other than those listed in these drug information articles. If you have not discussed this with your doctor or are not sure why you are taking this medication, speak to your doctor. Do not stop taking this medication without consulting your doctor.

Do not give this medication to anyone else, even if they have the same symptoms as you do. It can be harmful for people to take this medication if their doctor has not prescribed it.

How should I use this medication?

The recommended starting dose of lomitapide for adults is 5 mg taken once daily. After 2 weeks, the dose can be increased to 10 mg taken once daily. If necessary, the dose can be increased at 4 week intervals as it is tolerated. The maximum recommended dose is 60 mg daily. 

Lomitapide capsules should be swallowed whole with a glass of water. Do not open, crush, dissolve, or chew the capsules.

Food may cause side effects such as nausea and diarrhea, therefore, this medication should be taken without food, at least 2 hours after the evening meal.

Your doctor may also prescribe Vitamin E and essential fatty acids for you to take while you are taking lomitapide.  These supplements should not be taken at the same time as lomitapide. It is recommended that these dietary supplements be taken in the morning. 

Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are taking the medication without consulting your doctor.

It is important to take this medication exactly as prescribed by your doctor.

If you miss a dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed one. If you are not sure what to do after missing a dose, contact your doctor or pharmacist for advice.

Store this medication at room temperature, protect it from light and moisture, and keep it out of the reach of children.

Do not dispose of medications in wastewater (e.g. down the sink or in the toilet) or in household garbage. Ask your pharmacist how to dispose of medications that are no longer needed or have expired.
