As a cholesterol absorption inhibitor, it works in the digestive tract by blocking the absorption of cholesterol from the foods you eat. This drug is effective at decreasing total cholesterol and "bad cholesterol," as well as slightly decreasing triglycerides. By itself, however, it has little effect on "good cholesterol."
Ezetimibe comes as a tablet that is taken once a day, with or without food. Common side effects include fatigue, diarrhea, and headaches. However, it is generally well tolerated.
