Although adverse drug reactions are a well-recognized cause of mental status changes in the elderly, antimicrobials are not often implicated. Trimethoprim-sulfamethoxazole-induced hallucinations in immune-competent patient with switching to nitrofurantoin and risperidone, without associated polypharmacy, have not been reported in the literature. In this case report, we present an 86-year-old Caucasian immune-competent female with major depressive disorder and insomnia who developed hallucinations when treated with two trimethoprim-sulfamethoxazole tablets (80 mg/400 mg) in every 12 hours (4 tablets daily) because of lower urinary infection. After trimethoprim-sulfamethoxazole discontinuation and switching to nitrofurantoin and risperidone, symptoms significantly improved.

Rhabdomyolysis is a rare phenomenon that may be challenging to recognize in an emergency setting. Drugs are one of the common causes. Trimethoprim-sulfamethoxazole is a commonly used antibiotic effective in the treatment of upper and lower respiratory tract infections as well as renal, urinary, and gastrointestinal tract infections. It has variable side effects, ranging from mild symptoms of fatigue and insomnia to a potentially life-threatening Steven-Johnson syndrome and renal failure. Rhabdomyolysis is a rare complication of therapy with this drug and is commonly seen in immunocompromised patients or those with an allogenic stem cell transplant. In this article, we report a case of rhabdomyolysis in an immunocompetent patient who has undergone treatment with trimethoprim-sulfamethoxazole and a possible drug interaction with nonsteroidal anti-inflammatory drugs, with the latter acting as an aggravating factor of this complication.
