What Omacor is used for

Omacor is used, along with a low-fat and low-cholesterol diet, to lower very high triglycerides (fats) in blood. High levels of triglycerides may increase your risk of developing coronary heart disease. In most people there are no symptoms of high triglycerides.Your doctor can measure your triglyceride levels with a simple blood test.

How Omacor works

Omacor contains highly purified omega-3 polyunsaturated fatty acids. These fatty acids are natural substances found in the body oil of fat fish species that your body needs in sufficient amounts to provide energy. However, as the body cannot make enough on its own, the balance needs to be obtained in the diet.
Ask your doctor if you have any questions about why Omacor has been prescribed for you.
Your doctor may have prescribed it for another reason.
There is no evidence that this medicine is addictive.
Omacor is only available with a doctor’s prescription.
