Glipizide (the active ingredient contained in Glucotrol) has been usually well tolerated. Side effects were reported in 3% to 12% of patients in clinical trials. These effects were serious enough to result in discontinuation of therapy in only 0.3% to 3% of patients.
Hypoglycemia, an extension of glipizide (the active ingredient contained in Glucotrol) s pharmacologic effects, may be severe, protracted, refractory to glucose infusion, and, in some cases, may require diazoxide. Hypoglycemia may present as coma or disturbed consciousness. Other signs of hypoglycemia include tachycardia, tremors, and increased sweating. In one review of 19 spontaneously reported cases, the mean dose of glipizide associated with hypoglycemia was 10 mg per day. The mean age in these cases was 75 years. Two patients died, although their cases were complicated and the degree to which hypoglycemia contributed to their deaths cannot be ascertained.
Patients with renal dysfunction, liver disease, or adrenal or pituitary insufficiency may be at increased risk for hypoglycemia as are those who are elderly, debilitated, or malnourished. In addition, acute illness, lack of adherence to diet, ethanol ingestion, or strenuous exercise may precipitate hypoglycemia.

Hyponatremia, disulfiram-like reactions, and coproporphyria have also been reported. Elderly patients may be at increased risk for hypoglycemia based on case reviews demonstrating an increased proportion of severe hypoglycemic events in patients aged 60 years and older.

Dermatologic side effects have included rash in 0.5% to 1.4% of patients. Allergic skin reactions have occurred as well and included erythema, morbilliform or maculopapular eruptions, urticaria, pruritus, and eczema. Photosensitivity has been reported with other sulfonylureas.
