DOSAGE AND ADMINISTRATION
There is no fixed dosage regimen for the management of diabetes mellitus with glipizide or any other hypoglycemic agent. , loss of an adequate blood-glucose-lowering response after an initial period of effectiveness. Glycosylated hemoglobin levels may also be of value in monitoring the patient’s response to therapy.
Short-term administration of glipizide may be sufficient during periods of transient loss of control in patients usually controlled well on diet. In general, glipizide should be given approximately 30 minutes before a meal to achieve the greatest reduction in postprandial hyperglycemia.
Initial Dose The recommended starting dose is 5 mg, given before breakfast. 5 mg. 5 to 5 mg, as determined by blood glucose response. At least several days should elapse between titration steps. If response to a single dose is not satisfactory, dividing that dose may prove effective.
The maximum recommended once daily dose is 15 mg. Doses above 15 mg should ordinarily be divided and given before meals of adequate caloric content. The maximum recommended total daily dose is 40 mg. Maintenance Some patients may be effectively controlled on a once-a-day regimen, while others show better response with divided dosing.
Total daily doses above 15 mg should ordinarily be divided. d. basis to long-term patients. In elderly patients, debilitated or malnourished patients, and patients with impaired renal or hepatic function, the initial and maintenance dosing should be conservative to avoid hypoglycemic reactions (see PRECAUTIONS ).
Patients Receiving Insulin As with other sulfonylurea-class hypoglycemics, many stable non-insulin-dependent diabetic patients receiving insulin may be safely placed on glipizide. When transferring patients from insulin to glipizide, the following general guidelines should be considered: For patients whose daily insulin requirement is 20 units or less, insulin may be discontinued and glipizide therapy may begin at usual dosages.
Several days should elapse between glipizide titration steps. For patients whose daily insulin requirement is greater than 20 units, the insulin dose should be reduced by 50% and glipizide therapy may begin at usual dosages. Subsequent reductions in insulin dosage should depend on individual patient response.
ADVERSE REACTIONS
S. and foreign controlled studies, the frequency of serious adverse reactions reported was very low. 5% was glipizide discontinued. Hypoglycemia See PRECAUTIONS and OVERDOSAGE sections. Gastrointestinal Gastrointestinal disturbances are the most common reactions.
Gastrointestinal complaints were reported with the following approximate incidence: nausea and diarrhea, one in seventy; constipation and gastralgia, one in one hundred. They appear to be dose-related and may disappear on division or reduction of dosage.
Cholestatic jaundice may occur rarely with sulfonylureas: glipizide should be discontinued if this occurs. Dermatologic Allergic skin reactions including erythema, morbilliform or maculopapular eruptions, urticaria, pruritus, and eczema have been reported in about one in seventy patients.
These may be transient and may disappear despite continued use of glipizide; if skin reactions persist, the drug should be discontinued. Porphyria cutanea tarda and photosensitivity reactions have been reported with sulfonylureas. Hematologic Leukopenia, agranulocytosis, thrombocytopenia, hemolytic anemia (see PRECAUTIONS ), aplastic anemia, and pancytopenia have been reported with sulfonylureas.
Metabolic Hepatic porphyria and disulfiram-like reactions have been reported with sulfonylureas. In the mouse, glipizide pretreatment did not cause an accumulation of acetaldehyde after ethanol administration. Clinical experience to date has shown that glipizide has an extremely low incidence of disulfiram-like alcohol reactions.
Endocrine Reactions Cases of hyponatremia and the syndrome of inappropriate anti-diuretic hormone (SIADH) secretion have been reported with this and other sulfonylureas. Miscellaneous Dizziness, drowsiness, and headache have each been reported in about one in fifty patients treated with glipizide.
WARNINGS SPECIAL WARNING ON INCREASED RISK OF CARDIOVASCULAR MORTALITY The administration of oral hypoglycemic drugs has been reported to be associated with increased cardiovascular mortality as compared to treatment with diet alone or diet plus insulin.
This warning is based on the study conducted by the University Group Diabetes Program (UGDP), a long-term prospective clinical trial designed to evaluate the effectiveness of glucose-lowering drugs in preventing or delaying vascular complications in patients with non-insulin-dependent diabetes.
The study involved 823 patients who were randomly assigned to one of four treatment groups ( Diabetes , 19, supp. 2:747-830, 1970). 5 grams per day) had a rate of cardiovascular mortality approximately 2½ times that of patients treated with diet alone.
A significant increase in total mortality was not observed, but the use of tolbutamide was discontinued based on the increase in cardiovascular mortality, thus limiting the opportunity for the study to show an increase in overall mortality.
Despite controversy regarding the interpretation of these results, the findings of the UGDP study provide an adequate basis for this warning. The patient should be informed of the potential risks and advantages of glipizide and of alternative modes of therapy.
Although only one drug in the sulfonylurea class (tolbutamide) was included in this study, it is prudent from a safety standpoint to consider that this warning may also apply to other oral hypoglycemic drugs in this class, in view of their close similarities in mode of action and chemical structure.
CONTRAINDICATIONS
Glipizide is contraindicated in patients with: 1. Known hypersensitivity to the drug. 2. Type 1 diabetes mellitus, diabetic ketoacidosis, with or without coma. This condition should be treated with insulin.
Not medical advice. Always read the patient information leaflet and follow your prescriber or pharmacist.

Several days should elapse between glipizide titration steps. During the insulin withdrawal period, the patient should test urine samples for sugar and ketone bodies at least three times daily. Patients should be instructed to contact the prescriber immediately if these tests are abnormal.
In some cases, especially when patient has been receiving greater than 40 units of insulin daily, it may be advisable to consider hospitalization during the transition period. Patients Receiving Other Oral Hypoglycemic Agents As with other sulfonylurea-class hypoglycemics, no transition period is necessary when transferring patients to glipizide.
, chlorpropamide) to glipizide due to potential overlapping of drug effect. When colesevelam is co-administered with glipizide ER, maximum plasma concentration and total exposure to glipizide is reduced. Therefore, glipizide tablets should be administered at least 4 hours prior to colesevelam.
They are usually transient and seldom require discontinuance of therapy. Laboratory Tests The pattern of laboratory test abnormalities observed with glipizide was similar to that for other sulfonylureas. Occasional mild to moderate elevations of SGOT, LDH, alkaline phosphatase, BUN, and creatinine were noted.
One case of jaundice was reported. The relationship of these abnormalities to glipizide is uncertain, and they have rarely been associated with clinical symptoms. Post-Marketing Experience The following adverse events have been reported in post-marketing surveillance: Hepatobiliary Cholestatic and hepatocellular forms of liver injury accompanied by jaundice have been reported rarely in association with glipizide; glipizide should be discontinued if this occurs.
