Why is this medication prescribed?

People with very high triglycerides can lower their blood triglyceride levels by combining omega-3 fatty acids with lifestyle adjustments (diet, weight loss, exercise). A family of drugs known as antilipemic or lipid-regulating medicines includes omega-3 fatty acids. Reduced liver production of triglycerides and other lipids may be how omega-3 fatty acids act.

How should this medicine be used?

Prescription omega-3 fatty acids are available as liquid-filled gel capsules to be swallowed, such as omega-3 acid ethyl esters (Lovaza, Omytrg), icosapent ethyl esters (Vascepa), and omega-3 carboxylic acids (Epanova). The normal dosage of Epanova is one dose per day, with or without food. Typically, lovaza is taken once or twice daily, with or without food. Omytrg is typically taken with food once or twice per day. Vascepa is typically taken with meals twice a day. Omega-3 fatty acids sold over-the-counter come in gel capsules that are to be swallowed as advised on the label of the container. Take your daily dose of omega-3 fatty acids at around the same time(s). Ask your doctor or chemist to clarify any instructions on your prescription label or box that you do not understand, and carefully follow them. Take omega-3 fatty acids as prescribed. Never take it in quantities or frequencies other than those recommended by your doctor.

Do not split, chew, crush, dissolve, or split the capsules; instead, swallow them whole. Inform your doctor if you have trouble swallowing capsules whole.

As many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and are simple for young children to open, it is crucial to keep all medications out of sight and out of reach of children. Always lock safety caps and promptly stash medication up and away from young children where it is out of their sight and reach to prevent poisoning.
