Are there any safety issues associated with omega 3 supplements?

The only contraindication to their use is known hypersensitivity to omega 3 fish oils (such as anaphylaxis), EPA, DHA or any of its components. Care should be exercised during pregnancy or lactation, in patients facing surgery, those with bleeding problems or in patients undergoing any other treatment (either drug therapies or nutritional supplements) which may affect the ability of the blood to clot. Routine liver function tests should be performed, specifically when higher doses are being utilized. There are no known interactions with foods. Using fish oil supplements concomitantly with drugs that lower blood pressure (i.e., captopril, and enalapril, losartan, diltiazem, amlodipine, hydrochlorothiazide, furosemide, and others) may increase the effect of these drugs and may excessively lower blood pressure in some patients. The most commonly reported adverse reactions to fish oil therapy include “burping”, dyspepsia, and taste perversion.
