Drug Interactions With Omega-3 Fatty Acids

Many medications can cause potentially dangerous drug interactions with omega-3 fatty acids, including orlistat and medicines that have anticoagulant or antiplatelet activity. Taking medicines that "thin" the blood (such as warfarin or aspirin) with omega-3 may increase your risk of bleeding. To help prevent drug interactions with omega-3 fatty acids, tell your healthcare provider about all other medications you are taking before starting the supplement.
