What is Vytorin?
Simvastatin belongs to a group of drugs called HMG CoA reductase inhibitors, or "statins."
Vytorin is used to lower blood levels of "bad" cholesterol (low-density lipoprotein, or LDL) and triglycerides, to increase levels of "good" cholesterol (high-density lipoprotein, or HDL), and to lower triglycerides (a type of fat in the blood).
Vytorin is used together with a low-fat diet and other treatments to lower total cholesterol in adults and children who are at least 10 years old. It is not known whether this medicine reduces your risk of heart disease.
Do not use Vytorin if you are pregnant or if you could become pregnant. Use effective birth control.
Do not breastfeed while using ezetimibe and simvastatin.
The following drugs should not be used while you are taking Vytorin: boceprevir, cyclosporine, danazol, gemfibrozil, nefazodone, telaprevir, certain antibiotics (clarithromycin, erythromycin, telithromycin), antifungal medication (itraconazole, ketoconazole, posaconazole, voriconazole), or certain HIV/AIDS medication (atazanavir, cobicistat (Stribild, Tybost), indinavir, nelfinavir, ritonavir, saquinavir, tipranavir).
