Phentermine-Associated Atrial Fibrillation: A Case Report and Literature Review

Abstract

Obesity has become a major public health problem with increased prevalence and is associated with cardiovascular mortality. Phentermine is approved for short-term obesity treatment in conjunction with lifestyle modifications. Palpitations are a well-documented side effect of phentermine, but atrial fibrillation (AF) is rarely reported. We present a case of new-onset AF in a healthy woman who had been recently started on phentermine for weight loss.
