title: Omega-3 Fatty Acid Supplementation and Warfarin: A Lethal Combination in Traumatic Brain Injury.
abstract: Polyunsaturated fatty acids such as omega-3 eicosapentaenoic acid and omega-6 docosahexaenoic acid, found in over-the-counter fish oil supplements, are often consumed for their beneficial, prophylactic, anti-inflammatory effects. Although the mechanisms of action are not fully known, a diet rich in polyunsaturated fats may reduce the risk of hyperlipidemia, atherosclerosis, high low-density lipoprotein cholesterol levels, hypertension, and inflammatory diseases. Masked by its many benefits, the risks of omega-3 fatty acid supplementation are often underappreciated, particularly its ability to inhibit platelet aggregation and promote bleeding in patients taking anticoagulant medications. The following details the clinical case of an elderly patient taking warfarin and fish oil supplementation whose warfarin-induced coagulopathy could not be reversed after suffering blunt head trauma.
