Key takeaways
Ezetimibe (brand name Zetia) and Vytorin (ezetimibe/simvastatin) are both used to lower cholesterol, but they have some differences in how they work. Ezetimibe is a cholesterol absorption inhibitor that lowers "bad" cholesterol (LDL) by blocking its absorption in the gut. It is usually taken once a day and can be used alone or with other medications, especially if you can't take statins. Vytorin, on the other hand, combines ezetimibe with simvastatin, a statin that blocks an enzyme in the liver from making cholesterol. This combination not only lowers LDL but also raises "good" cholesterol (HDL) and lowers triglycerides. Vytorin is typically taken in the evening and is more effective when taken at night due to the short-acting nature of simvastatin. While both medications can cause muscle pain, Vytorin has a higher risk of severe muscle problems like rhabdomyolysis, especially at higher doses. Additionally, Vytorin is not safe for use during pregnancy or breastfeeding, whereas the safety of ezetimibe alone in these conditions is less clear. Both medications are available in generic forms, making them more affordable options.
