Sulfamethoxazole/Trimethoprim induced liver failure: a case report

Abstract

Sulfamethoxazole/Trimethoprim (SMX/TMP) is a commonly used antibiotic, its' known adverse reaction of hepatotoxicity leading to acute liver failure is considered rare. We present a case of a 22 year old female who developed jaundice and acute liver failure one week after taking SMX/TMP for a UTI. After an extensive work up, a clinical diagnosis of SMX/TMP induced liver failure was reached. Over the course of several weeks she made a good clinical and biochemical recovery with supportive care. In this case report we describe her clinical presentation and course, and present a brief review of the literature.
