Common Use

Glyburide contains glyburide, a medication that lowers blood glucose levels. It belongs to the sulfonylureas class of diabetic drugs. Insulin is produced in the pancreas and helps reduce glucose synthesis in the liver while stimulating the body's cells to absorb glucose from the blood. Patients with type 2 diabetes either do not produce enough insulin or cannot use insulin effectively. This leads to increased glucose production by the liver, and the pancreas cannot compensate adequately. Glyburide works by stimulating the pancreas to release more insulin.

Dosage and Direction

The initial dose of Glyburide is 2.5-5 mg per day. The maximum daily dose ranges from 1.25-20 mg. Take Glyburide with the first main meal of the day.

Precautions

• Inform your doctor if you have heart conditions, as Glyburide may worsen heart problems compared to diet or insulin therapy.
• Regular blood and urine tests are recommended to monitor glucose levels.
• Follow your doctor's diet and treatment recommendations.
• Effectiveness may decrease over time due to reduced drug response or diabetes progression.
• Avoid use during pregnancy or breastfeeding unless approved by a doctor.

Contraindications

Do not use Glyburide if you have:

• Allergies to sulfonylureas like chlorpropamide or glipizide.
• Diabetic ketoacidosis (symptoms include nausea, fatigue, excessive thirst, abdominal pain, and fruity breath).

Possible Side Effects

Common side effects include:

• Nausea, bloating, heartburn
• Rashes, blurred vision
• Low blood sugar (hypoglycemia), weight gain

Rare but serious side effects:

• Hepatitis, jaundice, hyponatremia

Higher hypoglycemia risk in:

• Elderly, undernourished, or weak individuals
• Those with liver, kidney, adrenal, or pituitary disorders

Avoid alcohol, skipped meals, and unprescribed medications to reduce risks.

Drug Interactions

Avoid combining Glyburide with:

• Bosentan (Tracleer) - increases liver toxicity and reduces effectiveness.
• Thiazide diuretics (e.g., hydrochlorothiazide) - may raise blood glucose.

Also notify your doctor if taking:

• Fluoroquinolone antibiotics (levofloxacin, ciprofloxacin)
• Beta blockers (atenolol, propranolol)
• Blood thinners (warfarin), NSAIDs (ibuprofen, naproxen)
• Oral contraceptives, steroids, or other diabetes medications.

Missed Dose

Take a missed dose as soon as you remember. If it's almost time for the next dose, skip the missed one. Do not double the dose. Resume your regular schedule the next day.

Overdose

Symptoms of overdose include:

• Pale skin, seizures, coma
• Shallow breathing, severe hypoglycemia

Seek emergency medical help immediately if these occur.

Storage

Store at room temperature (59-77°F / 15-25°C) away from light, moisture, children, and pets. Do not use after expiration.
