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.[3] Together with dietary changes, they are used to treat high blood triglycerides which may reduce the risk of pancreatitis.[3][4] 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.[3][5][6] Omega-3-acid ethyl esters are taken by mouth.[3]

Common side effects include burping, nausea, and an upset abdomen.[3][5] Serious side effects may include liver problems and anaphylaxis.[3] While use in pregnancy has not been well studied, some omega-3 fatty acids appear beneficial.[1] How it works is not entirely clear.[3]

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.[3][6][7] Beyond the branded prescription formulation, it is also available as a generic medication and over the counter.[3][5] In 2021, it was the 218th most commonly prescribed medication in the United States, with more than 1 million prescriptions.[8][9]
