Before Using This Medicine
It is essential to inform your doctor about the following:
Any allergies you have, including allergies to this medication, its components, or other substances, such as foods or drugs. Be sure to describe the allergic reaction you experienced.
A known sulfa allergy.
Any narrowing of the gastrointestinal (GI) tract or a bowel blockage.
Acidic blood conditions, such as acidosis.
* If you have type 1 diabetes, as this medication is not intended to treat this condition.
This list is not exhaustive, and it is crucial to discuss all your medications, including prescription and over-the-counter (OTC) drugs, natural products, and vitamins, with your doctor and pharmacist. They will help you determine if it is safe to take this medication with your other medications and health conditions.
Remember, do not start, stop, or change the dose of any medication without first consulting your doctor to ensure your safety.
Precautions & Cautions
Regular blood tests will be necessary, as directed by your doctor. Be sure to discuss any concerns or questions with your doctor during these appointments. Additionally, inform all healthcare providers and laboratory personnel that you are taking this medication, as it may impact certain lab test results.
Adhere to the diet and exercise plan recommended by your doctor. If you experience low blood sugar, avoid driving, as this can increase your risk of being involved in an accident. It is also recommended to avoid consuming alcohol while taking this medication.
If you are taking colesevelam, take it at least 4 hours after taking this drug. Be aware that stress, such as fever, infection, injury, or surgery, can affect blood sugar control. Changes in physical activity, exercise, or diet may also impact blood sugar levels.
Individuals with low levels of the enzyme G6PD should exercise caution, as they may be more prone to anemia. This enzyme deficiency is more common in patients of African, South Asian, Middle Eastern, and Mediterranean descent.
There is an increased risk of death from heart disease associated with this medication. Discuss this risk with your doctor. Low blood sugar is a potential side effect, and severe cases can lead to seizures, loss of consciousness, long-term brain damage, and even death. Consult your doctor if you have concerns about low blood sugar.
If you are 65 or older, use this medication with caution, as you may be more susceptible to side effects. Pregnant or breastfeeding women should discuss the benefits and risks of this medication with their doctor. If you are planning to become pregnant, inform your doctor, as you will need to weigh the advantages and disadvantages of taking this medication.
You may notice the tablet shell in your stool, but this is a normal occurrence and not a cause for concern. However, if you are taking this medication during pregnancy, you will need to stop taking it before your due date to minimize the risk of low blood sugar in your infant. Consult your doctor for guidance on managing this risk.
Overdose Information
Overdose Symptoms:
- Severe hypoglycemia (very low blood sugar)
- Confusion
- Slurred speech
- Seizures
- Loss of consciousness
- Coma
What to Do:
Immediately consume a source of fast-acting sugar. If the person is unconscious or unable to swallow, call 911 or emergency medical services. Glucagon injection may be necessary. Call 1-800-222-1222 (Poison Control) for further guidance.
Drug Interactions
Major Interactions

Monitoring
Baseline Monitoring
Rationale: To establish baseline glycemic control and guide initial dosing.
Timing: Prior to initiation of therapy.
Rationale: To establish baseline glycemic control and guide initial dosing.
Timing: Prior to initiation of therapy.
Rationale: To assess kidney function, as glipizide is primarily renally excreted and dose adjustments may be needed in impairment.
Timing: Prior to initiation of therapy.
Rationale: To assess liver function, as glipizide is extensively metabolized by the liver and dose adjustments may be needed in impairment.
Timing: Prior to initiation of therapy.
Routine Monitoring
Frequency: Every 3-6 months
Target: <7% (individualized based on patient factors)
Action Threshold: If HbA1c remains above target, consider dose adjustment or addition/change of therapy.
Frequency: Daily (frequency depends on patient and treatment regimen)
Target: FPG: 80-130 mg/dL; Postprandial: <180 mg/dL (individualized)
Action Threshold: Persistent readings outside target range, or frequent hypoglycemic episodes, warrant dose adjustment or re-evaluation of therapy.
Frequency: Continuously
Target: N/A
Action Threshold: Immediate intervention (e.g., consume fast-acting carbohydrates) if symptoms occur. Review medication regimen.
Frequency: Annually or more frequently if clinically indicated (e.g., in elderly or those with comorbidities)
Target: N/A
Action Threshold: Dose adjustment may be needed if renal function declines.
Frequency: Annually or more frequently if clinically indicated
Target: N/A
Action Threshold: Dose adjustment or discontinuation may be needed if hepatic function declines or liver injury is suspected.
Symptom Monitoring

- Tremor
- Palpitations
- Anxiety
- Hunger
- Confusion
- Dizziness
- Headache

Special Patient Groups
Pregnancy
Generally not recommended during pregnancy. Insulin is the preferred treatment for diabetes during pregnancy due to better glycemic control and lower risk of fetal hypoglycemia. Glipizide may cause severe neonatal hypoglycemia.
Trimester-Specific Risks:
Lactation
Not recommended during breastfeeding. Glipizide is excreted into breast milk and may cause hypoglycemia in the nursing infant. Insulin is generally preferred for managing diabetes in lactating mothers.
Pediatric Use
Safety and effectiveness have not been established in pediatric patients. Use is not recommended.
Geriatric Use
Use with caution in elderly patients due to increased risk of hypoglycemia, particularly in those with impaired renal or hepatic function. Start with a lower dose (e.g., 2.5 mg) and titrate slowly. Monitor blood glucose closely.
Clinical Information
Clinical Pearls
- Always instruct patients to take Glucotrol XL with their first main meal of the day (usually breakfast) to optimize absorption and reduce the risk of hypoglycemia.
- Emphasize the importance of consistent meal times and carbohydrate intake to prevent blood sugar fluctuations.
- Educate patients thoroughly on the signs and symptoms of hypoglycemia and how to treat it promptly.
- Be aware of drug interactions, especially with medications that can potentiate or diminish glipizide's hypoglycemic effect (e.g., beta-blockers, NSAIDs, fluconazole, corticosteroids).
- Consider alternative agents in patients with significant renal or hepatic impairment, or use with extreme caution and close monitoring.
- Glipizide ER tablets are designed to be swallowed whole and should not be chewed, crushed, or divided, as this can alter the extended-release properties and lead to rapid drug release and potential hypoglycemia.
Alternative Therapies
- Metformin
- Other sulfonylureas (e.g., glimepiride, glyburide)
- DPP-4 inhibitors (e.g., sitagliptin, saxagliptin)
- SGLT2 inhibitors (e.g., empagliflozin, dapagliflozin)
- GLP-1 receptor agonists (e.g., liraglutide, semaglutide)
- Thiazolidinediones (e.g., pioglitazone)
- Insulin therapy
