Enoxaparin-induced hepatotoxicity: an under-recognised complication of enoxaparin therapy.

Low-molecular-weight heparins including enoxaparin are commonly used for anticoagulation as prophylaxis and treatment for deep vein thrombosis (DVT). Prescribers of enoxaparin monitor for common side effects, such as bleeding and thrombocytopenia, but hepatotoxicity, a less common and under-reported adverse effect, may be overlooked. This report describes a case of enoxaparin-induced hepatotoxicity in a 57-year-old man who was started on the drug for a DVT. Within 3 days of taking enoxaparin, elevated transaminases were noted, and the drug was discontinued after 6 days. Similar to other published reports, the patient's transaminases peaked 1 day after discontinuation of the drug and then trended down to normal over 32 days. 2016 BMJ Publishing Group Ltd.
