The most serious side effect of sulfonylurea hypoglycemic drugs

Sulfonylureas, as one of the medications used in the treatment of type 2 diabetes, primarily lower blood glucose levels by stimulating insulin secretion from pancreatic β-cells. Their most serious side effect is hypoglycemic reaction.

Hypoglycemia may occur when the drug dosage is too high or when patients experience changes in lifestyle habits such as diet or physical activity. Hypoglycemic reactions may manifest as palpitations, excessive sweating, pallor, slowed response, nausea, and other symptoms; in severe cases, it may even lead to coma and cause significant harm to the patient's health.

Sulfonylureas may also cause other side effects, such as gastrointestinal discomfort, hematologic abnormalities, allergic reactions (e.g., rash, itching), and liver or kidney dysfunction. These side effects generally occur less frequently and are less severe compared to hypoglycemic reactions.

Therefore, to reduce the occurrence of sulfonylurea-related side effects, patients should regularly monitor blood glucose levels and adjust medication dosages according to their blood glucose status under professional guidance. At the same time, maintaining a balanced diet and engaging in appropriate physical activity can also help control blood glucose levels and reduce the occurrence of drug-related side effects.
