Generic name: ezetimibe and simvastatin

What is Vytorin?

Vytorin is a prescription medicine that contains 2 cholesterol lowering medicines, ezetimibe and simvastatin. Vytorin is used along with diet to:

  • lower the level of your "bad" cholesterol (LDL)
  • increase the level of your "good" cholesterol (HDL)
  • lower the level of fat in your blood (triglycerides)

Vytorin is for patients who cannot control their cholesterol levels by diet and exercise alone.

Vytorin has not been shown to reduce heart attacks or strokes more than simvastatin alone.

It is not known if Vytorin is safe and effective in children under 10 years of age or in girls who have not started their period (menses).

The usual dose of Vytorin is 10/10 mg to 10/40 mg 1 time each day.

Vytorin 10/80 mg increases your chance of developing muscle damage. The 10/80 mg dose should only be used by people who:

  • have been taking Vytorin 10/80 mg chronically (such as 12 months or more) without having muscle damage
  • do not need to take certain other medicines with Vytorin that would increase your chance of getting muscle damage.

If you are unable to reach your LDL-cholesterol goal using Vytorin 10/40 mg, your doctor should switch you to another cholesterol-lowering medicine.

Who should not take Vytorin?

Do not take Vytorin if you take:

  • Certain anti-fungal medicines including:
    • itraconazole
    • ketoconazole
    • posaconazole
    • voriconazole
  • HIV protease inhibitors (indinavir, nelfinavir, ritonavir, saquinavir, tipranavir, or atazanavir)
  • Certain hepatitis C virus protease inhibitors (such as boceprevir or telaprevir)
  • Certain antibiotics, including:
