Warnings

You should not use glyburide if you are being treated with bosentan (Tracleer), or if you have diabetic ketoacidosis (call your doctor for treatment). Glyburide is not for treating type 1 diabetes.

Before taking glyburide, tell your doctor if you are allergic to sulfa drugs, if you have been using insulin or chlorpropamide (Diabinese), or if you have hemolytic anemia (a lack of red blood cells), an enzyme deficiency (G6PD), a nerve disorder, liver disease, or kidney disease.

Take care not to let your blood sugar get too low. Low blood sugar (hypoglycemia) can occur if you skip a meal, exercise too long, drink alcohol, or are under stress. Symptoms include headache, hunger, weakness, sweating, tremor, irritability, or trouble concentrating. Carry hard candy or glucose tablets with you in case you have low blood sugar.
