Hypoglycemia is a frequent complication in diabetic patients. In most cases it occurs in relation to treatment with antidiabetic drugs or the use of insulin. Its prevention and immediate treatment is important, given the serious complications that can occur as a consequence, especially high mortality and neurological and cardiac sequelae. Hypoglycemia also occurs due to drugs other than those involved in antidiabetic treatment. We analyzed the clinical case of a patient with type 2 Diabetes Mellitus and Multiple Myeloma, who presented an infectious and respiratory complication of polychemotherapy. She required treatment with Trimetropim-Sulfamethoxazole, which produced hypoglycemia as an adverse effect, in a patient who had predisposing factors for its development and also in the context of drug-drug interactions.
After lowering the antibiotic dose, she did not repeat hypoglycemias, with good subsequent evolution. Hypoglycemia due to Trimethoprim-Sulfamethoxazole is an infrequent adverse effect. It is favored in patients who present predisposing factors for its development; in those who receive multiple drugs, pharmacological interactions and possible adverse effects should be taken into account when adding a new drug as described in the present clinical case.
