Hyperkalemia induced by trimethoprim-sulfamethoxazole therapy, described in 1983, is a frequent, yet less thought-off complication that can be dangerous and can cause death. There are conditions that increase the risk of presenting it, including, for example, diabetes mellitus and the use of renin-angiotensin system inhibition. This paper describes the case of a female patient who, on the third day of administration of trimethoprim-sulfamethoxazole for the management of a recurrent urinary tract infection, presented severe hyperkalemia, in the context of concomitant use of renin-angiotensin system inhibition, that was cured with antikalemic measures and with the suspension of antibiotic treatment.

Keywords : Hyperkalemia; Trimethoprim; Sulfamethoxazole.
