Hypoglycemia induced by the interaction of chlorpropamide and co-trimoxazole.
Sulfonylureas hypoglycemic action may be potentiated by sulfonamides. This case report describes a 69-year-old female with a hypoglycemic episode suggestive of an interaction between chlorpropamide and sulfamethoxazole (co-trimoxazole). The patient had no renal or liver dysfunction. This interaction is rare but one should be aware of it, especially with combination products.
