Omega-3-acid ethyl esters are a mixture of ethyl eicosapentaenoic acid and ethyl docosahexaenoic acid, which are ethyl esters of the omega−3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) found in fish oil.[4] Together with dietary changes, they are used to treat high blood triglycerides which may reduce the risk of pancreatitis.[4][5] They are generally less preferred than statins, and use is not recommended by NHS Scotland as the evidence does not support a decreased risk of heart disease.[4][6][7] Omega-3-acid ethyl esters are taken by mouth.[4]

Common side effects include burping, nausea, and an upset abdomen.[4][6] Serious side effects may include liver problems and anaphylaxis.[4] While use in pregnancy has not been well studied, some omega−3 fatty acids appear beneficial.[1] How it works is not entirely clear.[4]

Experts found a dose-dependent increase in the risk for atrial fibrillation in patients with cardiovascular diseases or cardiovascular risk factors who were being treated with omega-3-acid ethyl esters compared with those treated with placebo. The observed risk was at its highest at a dose of 4 g/d.[1]

Omega-3-acid ethyl ester medicines were approved for medical use in the European Union in 2000 and in the United States in 2004.[4][7][8] Beyond the branded prescription formulation, it is also available as a generic medication and over the counter.[4][6] In 2022, it was the 220th most commonly prescribed medication in the United States, with more than 1 million prescriptions.[9][10]
