Type 2 Diabetes Mellitus
Immediate-release tablet
- 5 mg PO qDay initially; increase by 2.5-5 mg PRN every several days based on blood glucose
- Maintenance range: 2.5-20 mg PO qDay or q12hr; not to exceed 40 mg/day
Extended-release tablets (Glucotrol XL)
- Initial: 5 mg/day PO given with breakfast; dose adjustment based on blood glucose should not be done more frequently than every 7 days
- Maintenance range: 5-10 mg PO qDay; not to exceed 20 mg/day
Dosing considerations
- Doses >15 mg: PO divided q12hr recommended
Conversion From Immediate Release to Extended Release
Administer the nearest equivalent immediate-release daily dose as extended-release tablet once daily
Alternatively, administer 5 mg PO initially; titrate as necessary
Conversion From Long Half-Life Agents
Observe patients carefully for 1-2 weeks when being converted from long half-life sulfonylureas to glipizide, because of potential for overlapping of hypoglycemic effects
Transferring From Insulin Therapy to Glipizide IR or ER
Current insulin dose <20 units: Discontinue insulin and initiate glipizide therapy at recommended dose
Current insulin dose >20 units: Decrease insulin dose by 50% and initiate glipizide at recommended dose; decrease insulin dose gradually based on patient’s response
Dosing Modifications
Hepatic impairment: 2.5 mg PO qDay initially (immediate release); extended release not studied
Renal impairment: Not studied; if GFR <50 mL/min, may decrease dose by 50% (suggested)
Safety and efficacy not established
Diabetes
2.5 mg PO qDay initially; increase by 2.5-5 mg/day every 1-2 weeks as determined by blood glucose response at intervals of several days
May switch to extended release once daily tablets at the nearest equivalent total daily dose or lower end of recommended range; not to exceed 20 mg/day
Dosing considerations
Because elderly patients are susceptible to the hypoglycemic effects of glucose-lowering drugs, the question of how tightly glucose levels should be controlled in the elderly is controversial
Recognizing hypoglycemia in elderly patients may be challenging
Monitoring other parameters associated with cardiovascular disease, such as blood pressure and cholesterol, may be more important than normalized glycemic control
Initial and maintenance dosing should be conservative

Type 1 diabetes
Diabetic ketoacidosis with or without coma
Cautions
Patients with risk of severe hypoglycemia include the elderly, debilitated, or malnourished; adrenal or pituitary insufficiency; stress due to infection, fever, trauma, or surgery; concomitant use with beta-blockers or other sympatholytic agents may impair the patient's ability to recognize the signs and symptoms of hypoglycemia; use with caution
If patient is exposed to stress (fever, trauma, infection, surgery), it may be necessary to discontinue glipizide and initiate insulin
Use caution in hepatic/renal impairment
Use with caution in pregnancy and lactation
Increased risk of cardiovascular mortality suggested by product labeling but data is limited
FDA-approved product labeling for many medications have included a broad contraindication in patients with a prior allregic reaction to sulfonamides; however, recent studies have suggested that crossreactivity between antibiotic sulfonamides and nonantibiotic sulfonamides is unlikely to occur; increase in cardiovascular mortality suggested by product labeling but data is limited
Hypoglycemia is more likely to occur when caloric intake is deficient, after severe or prolonged exercise, when alcohol is ingested, or when more than one glucose-lowering drug is used
Hypoglycemia may be difficult to recognize in patients with autonomic neuropathy
Hemolytic anemia may occur with glucose 6-phosphate dehydrogenase (G6PD) deficiency when treated with sulfonylurea agents; consider a nonsulfonylurea alternative
Avoid using the extended-release tablets in patients with severe gastrointestinal narrowing of esophageal dysmotility
Clinical studies have not found conclusive evidence that anti-diabetic drugs reduce macrovascular risk
Loss of efficacy following prolonged use possible; if no contributing factors, to explain loss of efficacy identified, consider discontinuing therapy; additional antidiabetic therapy will be required
Drug interactions overview
- The hypoglycemic action of sulfonylureas may be potentiated by certain drugs including nonsteroidal anti-inflammatory agents, some azoles, and other drugs that are highly protein bound, salicylates, sulfonamides, chloramphenicol, probenecid, coumarins, monoamine oxidase inhibitors, quinolones and beta adrenergic blocking agents; conversely, certain drugs tend to produce hyperglycemia and may lead to loss of control, including thiazides and other diuretics, corticosteroids, phenothiazines, thyroid products, estrogens, oral contraceptives, phenytoin, nicotinic acid, sympathomimetics, calcium channel blocking drugs, and isoniazid; when coadministering glipizide with such drugs, patient should be observed closely for hypoglycemia or hyperglycemia; when such drugs are withdrawn, observe patient closely for loss of control
Pregnancy & Lactation
Pregnancy
Available data from a small number of published studies and postmarketing experience with in pregnancy over decades have not identified any drug associated risks for major birth defects, miscarriage, or adverse maternal outcomes
However, sulfonylureas (including glipizide) cross the placenta and have been associated with neonatal adverse reactions such as hypoglycemia; therefore, therapy should be discontinued at least two weeks before expected delivery; poorly-controlled diabetes in pregnancy increases maternal risk for diabetic ketoacidosis, pre-eclampsia, miscarriage, preterm delivery, stillbirth, and delivery complications; poorly controlled diabetes increases fetal risk for major birth defects, stillbirth, and macrosomia related morbidity
Neonates of women with gestational diabetes who are treated with sulfonylureas during pregnancy may be at increased risk for neonatal intensive care admission and may develop respiratory distress, hypoglycemia, birth injury, and be large for gestational age; prolonged severe hypoglycemia, lasting 4-10 days, has been reported in neonates born to mothers receiving a sulfonylurea at the time of delivery and has been reported with the use of agents with a prolonged half-life; observe newborns for symptoms of hypoglycemia and respiratory distress and manage accordingly
Due to reports of prolonged severe hypoglycemia in neonates born to mothers receiving a sulfonylurea at time of delivery, therapy should be discontinued at least two weeks before expected delivery
Animal data
- No effects on embryofetal development reported in animal studies following administration of drug to pregnant rats and rabbits during organogenesis at doses 833 times and 8 times the human dose based on body surface area, respectively; however, increased pup mortality was observed in rats administered glipizide from gestation day 15 throughout lactation at doses 2 times the maximum human dose based on body surface area
Lactation
Breastfed infants of lactating women on therapy should be monitored for symptoms of hypoglycemia; although glipizide was undetectable in human milk in one small clinical lactation study; this result is not conclusive because of limitations of assay used in the study; there are no data on effects of glipizide on milk production; the developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for therapy and any potential adverse effects on the breastfed child from therapy or from the underlying maternal condition
Monitor breastfed infants for signs of hypoglycemia (e.g., jitters, cyanosis, apnea, hypothermia, excessive sleepiness, poor feeding, seizures)
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology

GLIPIZIDE TABLET - ORAL
(GLIP-i-zide)
COMMON BRAND NAME(S): Glucotrol
USES: Glipizide is used with a proper diet and exercise program to control high blood sugar in people with type 2 diabetes. It may also be used with other diabetes medications. Controlling high blood sugar helps prevent kidney damage, blindness, nerve problems, loss of limbs, and sexual function problems. Proper control of diabetes may also lessen your risk of a heart attack or stroke. Glipizide belongs to the class of drugs known as sulfonylureas. It lowers blood sugar by causing the release of your body's natural insulin.
HOW TO USE: Take this medication by mouth 30 minutes before breakfast or the first meal of the day as directed by your doctor, usually once daily. Some patients, especially those taking higher doses, may be directed to take this drug twice a day. The dosage is based on your medical condition and response to treatment.To reduce your risk of side effects, your doctor may direct you to start this medication at a low dose and gradually increase your dose. Follow your doctor's instructions carefully.If you are already taking another diabetes drug (such as chlorpropamide), follow your doctor's directions carefully for stopping the old drug and starting glipizide.Colesevelam can decrease the absorption of glipizide. If you are taking colesevelam, take glipizide at least 4 hours before taking colesevelam.Use this medication regularly to get the most benefit from it. To help you remember, take it at the same time(s) each day.Tell your doctor if your condition does not improve or if it worsens (your blood sugar is too high or too low).
SIDE EFFECTS: Nausea, vomiting, loss of appetite, diarrhea, constipation, upset stomach, headache, and weight gain may occur. If any of these effects last or get worse, tell your doctor or pharmacist promptly.Remember that this medication has been prescribed because your doctor has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.Tell your doctor right away if you have any serious side effects, including: signs of infection (such as sore throat that doesn't go away, fever), easy bleeding/bruising, stomach pain, yellowing eyes/skin, dark urine, unusual tiredness/weakness, unusual/sudden weight gain, mental/mood changes, swelling hands/feet, seizures.This medication can cause low blood sugar (hypoglycemia). This may occur if you do not consume enough calories from food or if you do unusually heavy exercise. Symptoms of low blood sugar include sudden sweating, shaking, fast heartbeat, hunger, blurred vision, dizziness, or tingling hands/feet. It is a good habit to carry glucose tablets or gel to treat low blood sugar. If you don't have these reliable forms of glucose, rapidly raise your blood sugar by eating a quick source of sugar such as table sugar, honey, or candy, or drink fruit juice or non-diet soda. Tell your doctor right away about the reaction and the use of this product. To help prevent low blood sugar, eat meals on a regular schedule, and do not skip meals. Check with your doctor or pharmacist to find out what you should do if you miss a meal.Symptoms of high blood sugar (hyperglycemia) include thirst, increased urination, confusion, drowsiness, flushing, rapid breathing, and fruity breath odor. If these symptoms occur, tell your doctor right away. Your dosage may need to be increased.A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.In the US -Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088 or at www.fda.gov/medwatch.In Canada - Call your doctor for medical advice about side effects. You may report side effects to Health Canada at 1-866-234-2345.
PRECAUTIONS: Before taking glipizide, tell your doctor or pharmacist if you are allergic to it; or if you have any other allergies. This product may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details.Before using this medication, tell your doctor or pharmacist your medical history, especially of: liver disease, kidney disease, thyroid disease, certain hormonal conditions (adrenal/pituitary insufficiency, syndrome of inappropriate secretion of antidiuretic hormone-SIADH), electrolyte imbalance (hyponatremia).You may experience blurred vision, dizziness, or drowsiness due to extremely low or high blood sugar. Do not drive, use machinery, or do any activity that requires alertness or clear vision until you are sure you can perform such activities safely.Limit alcohol while taking this medication because it can increase your risk of developing low blood sugar. Alcohol can rarely interact with glipizide and cause a serious reaction (disulfiram-like reaction) with symptoms such as facial flushing, nausea, vomiting, dizziness, or stomach pain. Consult your doctor or pharmacist about the safe use of alcohol.It may be harder to control your blood sugar when your body is stressed (such as due to fever, infection, injury, or surgery). Consult your doctor because this may require a change in your treatment plan, medications, or blood sugar testing.This medication may make you more sensitive to the sun. Limit your time in the sun. Avoid tanning booths and sunlamps. Use sunscreen and wear protective clothing when outdoors. Tell your doctor right away if you get sunburned or have skin blisters/redness.Before having surgery, tell your doctor or dentist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products).Older adults may be more sensitive to the side effects of this drug, especially low blood sugar.During pregnancy, this medication should be used only when clearly needed. Pregnancy may cause or worsen diabetes. Discuss a plan with your doctor for managing your blood sugar while pregnant. Your doctor may substitute insulin for this drug during pregnancy. If glipizide is used, it may be switched to insulin at least 2 weeks before the expected delivery date because of glipizide's risk of causing low blood sugar in your newborn. Discuss the risks and benefits with your doctor.It is unknown if this medication passes into breast milk. However, similar drugs pass into breast milk. Consult your doctor before breast-feeding.
DRUG INTERACTIONS: See also How to Use section.Drug interactions may change how your medications work or increase your risk for serious side effects. This document does not contain all possible drug interactions. Keep a list of all the products you use (including prescription/nonprescription drugs and herbal products) and share it with your doctor and pharmacist. Do not start, stop, or change the dosage of any medicines without your doctor's approval.Many drugs can affect your blood sugar, making it harder to control. Before you start, stop, or change any medication, talk with your doctor or pharmacist about how the medication may affect your blood sugar. Check your blood sugar regularly as directed and share the results with your doctor. Tell your doctor right away if you have symptoms of high or low blood sugar. (See also Side Effects section.) Your doctor may need to adjust your diabetes medication, exercise program, or diet.Beta-blocker medications (including metoprolol, propranolol, glaucoma eye drops such as timolol) may prevent the fast/pounding heartbeat you would usually feel when your blood sugar falls too low (hypoglycemia). Other symptoms of low blood sugar such as dizziness, hunger, or sweating are unaffected by these drugs.Check the labels on all your medicines (such as cough-and-cold products) because they may contain ingredients that could affect your blood sugar. Ask your pharmacist about using those products safely.
OVERDOSE: If someone has overdosed and has serious symptoms such as passing out or trouble breathing, call 911. Otherwise, call a poison control center right away. US residents can call their local poison control center at 1-800-222-1222. Canada residents can call a provincial poison control center. Symptoms of overdose may include: shakiness, fast heartbeat, sweating, loss of consciousness.
NOTES: Do not share this medication with others.Attend a diabetes education program to learn more about how to manage your diabetes with medications, diet, exercise, and regular medical exams.Learn the symptoms of high and low blood sugar and how to treat low blood sugar. Check your blood sugar regularly as directed.Keep all regular medical and laboratory appointments. Laboratory and/or medical tests (such as liver and kidney function tests, fasting blood glucose, hemoglobin A1c, complete blood counts) should be performed periodically to monitor your progress or check for side effects.
