Drugs & Medications




Omega-3 acid ethyl esters, a type of fat found in fish oil, is used along with diet and exercise to help lower levels of a certain blood fat (triglyceride). It may also raise "good" cholesterol (HDL). In general, this drug is used after your blood fat levels have not been fully controlled by non-drug treatments (such as diet changes, exercise, decreasing alcohol intake, weight loss if overweight, controlling blood sugar if diabetic, and regulating your thyroid hormone levels).

Lowering triglycerides and increasing "good" cholesterol may help decrease the risk for strokes and heart attacks. Omega-3 acid ethyl esters are thought to work by decreasing the amount of triglyceride the body makes.
