Vytorin

Vytorin is a prescription medication used in combination with diet and exercise to treat high cholesterol. It is also used to lower cholesterol in people with homozygous familial hypercholesterolemia (HoFH, a hereditary disorder that causes high cholesterol levels).

This medication is a single tablet containing two prescription medicines, ezetimibe and simvastatin. Ezetimibe belongs to a group of drugs called cholesterol absorption inhibitors, which block the absorption of cholesterol from the intestines. Simvastatin belongs to a group of drugs called HMG-CoA reductase inhibitors, also known as statins, which block an enzyme in the body called HMG-CoA reductase. This is a major enzyme involved in making cholesterol in the body.

This medication comes in tablet form and is usually taken once daily, in the evening. Vytorin can be taken with or without food.

Common side effects of Vytorin include headache, muscle pain, and diarrhea.

Vytorin is a prescription medicine used to lower levels of total cholesterol, LDL (bad) cholesterol, and fatty substances called triglycerides in the blood. In addition, Vytorin raises levels of HDL (good) cholesterol. 

Vytorin is also used to lower cholesterol in people with homozygous familial hypercholesterolemia (HoFH, a hereditary disorder that causes high cholesterol levels).

This medication may be prescribed for other uses. Ask your doctor or pharmacist for more information.

See your doctor regularly to check your cholesterol level and to check for side effects. Your doctor should do blood tests to check your liver before you start taking Vytorin  and if you have any symptoms of liver problems while you take Vytorin. Call your doctor right away if you have the following symptoms of liver problems:

• feel tired or weak
• loss of appetite
• upper belly pain
• dark urine
• yellowing of your skin or the whites of your eyes

In clinical studies patients reported the following common side effects while taking Vytorin: headache, muscle pain, and diarrhea.

Tell your doctor if you are having these or any other medical problems while on Vytorin. This is not a complete list of side effects. For a complete list, ask your doctor or pharmacist.

Tell your doctor about all the medicines you take including prescription and non-prescription medicines, vitamins, and herbal supplements. Especially tell your doctor if you take:

• Certain anti-fungal medicines including:
  • itraconazole
  • ketoconazole
  • posaconazole
• HIV protease inhibitors (indinavir, nelfinavir, ritonavir, saquinavir, tipranavir, or atazanavir),
• Certain antibiotics, including:
  • erythromycin
  • clarithromycin
  • telithromycin
• nefazodone
• A fibric acid medicine for lowering cholesterol called gemfibrozil
• cyclosporine
• danazol

Taking Vytorin with certain substances can increase the risk of muscle problems. It is especially important to tell your doctor if you take:

• fibric acid derivatives (such as fenofibrate)
• amiodarone (a drug used to treat an irregular heartbeat)
• verapamil, diltiazem, amlodipine, or ranolazine (drugs used to treat high blood pressure, chest pain associated with heart disease, or other heart conditions)
• large quantities of grapefruit juice (more than 1 quart daily)
• colchicine (a medicine used to treat gout)
• voriconazole (an anti-fungal medicine)
• large doses of niacin or nicotinic acid

Tell your doctor if you are taking niacin or a niacin-containing product, as this may increase your risk of muscle problems, especially if you are Chinese.

It is also important to tell your doctor if you are taking coumarin anticoagulants (drugs that prevent blood clots, such as warfarin).

Vytorin includes a statin medication called simvastatin. Statin medications carry a rare but serious risk of:

• liver damage
• memory loss or confusion
• increase in blood sugar levels (hyperglycemia)
• type 2 diabetes
• immune-mediated muscle breakdown

Certain statins can increase risk of muscle weakness as well.  It is important to consult your physician to discuss the benefits and risks associated with using this medication.

Do not take Vytorin:

• If you are allergic to ezetimibe or simvastatin, or to the inactive ingredients.
• If you have active liver disease or repeated blood tests indicating possible liver problems.
• If you are pregnant, or think you may be pregnant, or planning to become pregnant or breastfeeding.
• If you are a woman of childbearing age, you should use an effective method of birth control to prevent pregnancy while using Vytorin.
