Omega-3 (Omega-3-acid ethyl esters) — Uses, Dosage, Side Effects & Safety

Drug class: Antihyperlipidemic (Omega-3 fatty acids)

Overview

Omega-3 refers to a group of essential fatty acids, primarily eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), commonly found in fish oil and certain plant oils. Prescription omega-3 products are used to lower high triglyceride levels in adults, which can help reduce the risk of heart disease and pancreatitis. Omega-3 works by decreasing the amount of triglycerides and other fats made in the liver. It may also have anti-inflammatory and antithrombotic effects, supporting cardiovascular health. Key points: Omega-3 is not a substitute for a healthy diet or other cholesterol-lowering medications. Patients should use it under medical supervision, especially if they have bleeding disorders or take anticoagulants.
