In recent years, testosterone replacement therapy (TRT) has received significant media attention, and the rate of testosterone use has increased notably. A reported association between testosterone use and increased occurrence of myocardial infarction and stroke prompted the FDA to issue a safety bulletin in 2014. Clinical hypogonadism is the only FDA-approved indication for TRT in men; it is not approved to treat age-related low testosterone. Although it is not indicated, TRT is often recommended to improve sexual function, bone density, body composition, muscle strength, mood, behavior, and cognition. The literature on the effectiveness of TRT for various conditions is largely mixed; therefore, current data on appropriate and potentially inappropriate use are important for pharmacists to keep abreast of and discuss with patients.
