Omega-3-acid ethyl esters may be used as a cardiovascular system drug. It works as a lipid regulating agent to reduce blood level of triglycerides. The treatment can be used in combination with diet, exercise, and weight loss. In some nations, this medicine will need to be prescribed by a doctor.

This drug is thought to work by causing the liver to decrease its production of triglycerides. Blood triglyceride reduction may follow. This antilipemic is prescribed to help prevent triglycerides from causing blood vessel blockages.

The medicine frequently comes as a liquid filled capsule, which should be taken according to doctor’s instructions. Correct dosage amounts will vary according to the patient’s size and triglyceride levels. Effects of this medication may not be immediate, but tend to build over time.

If prescribed omega-3-acid ethyl esters, the patient should request an ingredient list from a pharmacist and check if he is allergic to fish or to any other ingredients. The medicine may also interact with supplements or other medications, so patients should discuss these with their doctor. Some medicines that are of concern are blood thinners, aspirin and those that contain aspirin, beta blockers, diuretics, and estrogens.
