The Pharmacist’s Take By · Clinical pharmacist · Written

Glyburide is a sulfonylurea for type 2 diabetes that prompts the pancreas to release more insulin, so it works only while those insulin-making cells still function; on the market since about 1984 and available as a generic, it is a familiar older standby, usually added to metformin rather than chosen first. Most people tolerate it well, and the side effects they notice are mostly mild stomach complaints like nausea, heartburn or upper-stomach fullness. The real risk is low blood sugar, especially after a skipped meal or in older adults and anyone with kidney problems; learn its warning signs and treat confusion or passing out as an emergency.

Clinical pearls

  • Take it with breakfast or your first main meal, so the insulin boost it triggers lines up with food.
  • If you take colesevelam for cholesterol, take glyburide at least 4 hours before it, or less of it gets absorbed.
  • Bosentan must never be combined with it, and ciprofloxacin, oral miconazole or NSAID pain relievers can drive blood sugar dangerously low.
  • Tell your prescriber about any sulfa drug allergy, because people allergic to sulfonamides may react to glyburide too.

Patient information guide A plain-language walkthrough of Glyburide, written from its FDA label.

What Glyburide is used for

▾

Glyburide is used for one main purpose:

  • Glyburide tablets, along with diet and exercise, improve blood sugar control in adults with type 2 diabetes.

How Glyburide works

▾

Glyburide mainly works by prompting the pancreas to release insulin. This depends on having working beta cells (the insulin-making cells) in the pancreas.

How it keeps lowering blood sugar over the long term isn't clear. Some people respond less well over time. Some who stopped responding to other sulfonylureas may still respond to glyburide.

Glyburide dosage

▾

Glyburide is taken by mouth as a tablet, usually with breakfast or the first main meal. Many people take it once a day. Some take it twice a day.

  • Your prescriber adjusts the dose slowly based on blood sugar results.
  • Take it at least 4 hours before colesevelam if you use both.
  • It can be combined with metformin when metformin alone isn't enough.

Follow your prescriber's directions and the pharmacy label.

Dosing details from the FDA-approved label

From the Glyburide prescribing information (“Dosage and Administration”). Doses are set by your prescriber for your product, condition, kidney function and age — never change a dose on your own.

  • Usual starting dose
    • 2.5 to 5 mg daily, administered with breakfast or the first main meal
    • Patients who may be more sensitive to hypoglycemic drugs should be started at 1.25 mg daily
  • Transfer from other oral antidiabetic therapy
    • Initial daily dose should be 2.5 to 5 mg
    • Transfer conservatively; no transition period or priming dose when transferring from agents other than chlorpropamide; when transferring from chlorpropamide, take particular care during the first two weeks
  • Patients receiving insulin, less than 20 units daily
    • Substitution of glyburide tablets 2.5 to 5 mg as a single daily dose may be tried
  • Patients receiving insulin, between 20 and 40 units daily
    • Placed directly on glyburide tablets 5 mg daily as a single dose
  • Patients receiving insulin, more than 40 units daily
    • Insulin dosage is decreased by 50% and glyburide tablets 5 mg daily is started
    • Progressive withdrawal of insulin and increase of glyburide tablets in increments of 1.25 to 2.5 mg every 2 to 10 days
    • A transition period is required; hypoglycemia may occur during conversion
  • Maintenance dose (titration)
    • Usual maintenance dose is 1.25 to 20 mg daily, as a single dose or in divided doses
    • Increases in increments of no more than 2.5 mg at weekly intervals based on blood glucose response
    • Maximum: Daily doses of more than 20 mg are not recommended
    • Once-a-day therapy is usually satisfactory; some patients, particularly those receiving more than 10 mg daily, may respond better to twice-a-day dosage
  • Concomitant glyburide and metformin therapy
    • Add glyburide gradually to the regimen of patients who have not responded to the maximum dose of metformin monotherapy after four weeks
    • Adjust the dose of each drug
    • Risk of hypoglycemia continues and may be increased
  • Patients receiving colesevelam
    • Glyburide tablets should be administered at least 4 hours prior to colesevelam
  • Elderly, debilitated or malnourished patients, and patients with impaired renal or hepatic function
    • Initial and maintenance dosing should be conservative
    • To avoid hypoglycemic reactions
  • Pregnancy and pediatric patients
    • Not recommended for use

DOSAGE AND ADMINISTRATION There is no fixed dosage regimen for the management of diabetes mellitus with glyburide tablets. In addition to the usual monitoring of urinary glucose, the patient's blood glucose must also be monitored periodically to determine the minimum effective dose for the patient; to detect primary failure, i.e. , inadequate lowering of blood glucose at the maximum recommended dose of medication; and to detect secondary failure, i.e. , loss of 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 glyburide tablets may be sufficient during periods of transient loss of control in patients usually controlled well on diet. Usual Starting Dose The usual starting dose of glyburide tablets is 2.5 to 5 mg daily, administered with breakfast or the first main meal. Those patients who may be more sensitive to hypoglycemic drugs should be started at 1.25 mg daily. (See PRECAUTIONS section for patients at increased risk.) Failure to follow an appropriate dosage regimen may precipitate hypoglycemia. Patients who do not adhere to their prescribed dietary and drug regimen are more prone to exhibit unsatisfactory response to therapy. Transfer From Other Hypoglycemic Therapy Patients Receiving Other Oral Antidiabetic Therapy Transfer of patients from other oral antidiabetic regimens to glyburide tablets should be done conservatively and the initial daily dose should be 2.5 to 5 mg. When transferring patients from oral hypoglycemic agents other than chlorpropamide to glyburide tablets, no transition period and no initial or priming dose are necessary. When transferring patients from chlorpropamide, particular care should be exercised during the first two weeks because the prolonged retention of chlorpropamide in the body and subsequent overlapping drug effects may provoke hypoglycemia. Patients Receiving Insulin Some Type II diabetic patients being treated with insulin may respond satisfactorily to glyburide tablets. If the insulin dose is less than 20 units daily, substitution of glyburide tablets 2.5 to 5 mg as a single daily dose may be tried. If the insulin dose is between 20 and 40 units daily, the patient may be placed directly on glyburide tablets 5 mg daily as a single dose.

Glyburide side effects

▾

The most common side effects are stomach-related, and they often ease if the dose is lowered.

Common side effects

  • Nausea
  • Fullness in the upper stomach
  • Heartburn
  • Itching, redness, hives or skin rash
  • Low blood sugar (hypoglycemia)
  • Blurred vision linked to changing blood sugar levels

When to get medical help

  • Signs of severe low blood sugar, such as confusion, seizure or passing out: this is an emergency and needs immediate medical care
  • Yellow skin or eyes, or signs of liver problems
  • Skin reactions that don't go away
  • Swelling of the face or throat, joint or muscle pain, or other signs of a serious allergic reaction
  • Unusual bruising, bleeding, frequent infections or severe tiredness, which can signal blood cell problems
  • Skin that becomes very sensitive to sunlight

Glyburide warnings and precautions

▾
  • Low blood sugar is the biggest risk, especially if you skip meals or don't follow your dosing plan.
  • Diabetes pills in this class have been linked to a higher risk of death from heart and blood vessel problems.
  • People allergic to sulfa drugs may react to glyburide.
  • Rare liver, blood cell and low sodium problems have been reported.
  • Your blood sugar needs regular checking to confirm the drug is working.

Glyburide interactions

▾

Many medicines can push your blood sugar too low or too high while you take glyburide.

  • Bosentan: must not be combined; raises liver enzyme risk.
  • NSAIDs, salicylates, sulfonamides, chloramphenicol, probenecid, warfarin-type drugs, MAO inhibitors, beta blockers: can increase low blood sugar risk.
  • Ciprofloxacin and oral miconazole: can cause low blood sugar, sometimes severe.
  • Diuretics, corticosteroids, thyroid products, estrogens, birth control pills, phenytoin, niacin and others: can raise blood sugar and weaken control.
  • Colesevelam: reduces glyburide absorption; take glyburide at least 4 hours earlier.
  • Topiramate: lowers glyburide levels somewhat.

Interactions listed in the FDA-approved label

From the Glyburide prescribing information (“Drug Interactions”): what the manufacturer studied or reported to the FDA.

  • Non-steroidal anti-inflammatory agents and other highly protein-bound drugs, salicylates, sulfonamides, chloramphenicol, probenecid, coumarins, monoamine oxidase inhibitors, beta adrenergic blocking agents: The hypoglycemic action of sulfonylureas may be potentiated. Observe the patient closely for hypoglycemia when added, and for loss of control when withdrawn.
  • Bosentan: An increased risk of liver enzyme elevations was observed with concomitant use. Concomitant administration is contraindicated.
  • Thiazides and other diuretics, corticosteroids, phenothiazines, thyroid products, estrogens, oral contraceptives, phenytoin, nicotinic acid, sympathomimetics, calcium channel blocking drugs, isoniazid: These drugs tend to produce hyperglycemia and may lead to loss of control. Observe closely for loss of control when added, and for hypoglycemia when withdrawn.
  • Ciprofloxacin: A possible interaction has been reported, resulting in potentiation of the hypoglycemic action of glyburide; the mechanism is not known.
  • Miconazole (oral): A potential interaction with oral hypoglycemic agents leading to severe hypoglycemia has been reported. It is not known whether this occurs with intravenous, topical or vaginal miconazole.
  • Metformin: In a single-dose study, decreases in glyburide AUC and Cmax were observed but were highly variable; clinical significance is uncertain. Glyburide did not change metformin pharmacokinetics or pharmacodynamics.
  • Colesevelam: Coadministration reduced glyburide AUC and Cmax by 32% and 47%; reductions were 20% and 15% when glyburide was given 1 hour before, and not significantly changed (-7% and 4%) when given 4 hours before colesevelam. Administer glyburide at least 4 hours prior to colesevelam.
  • Topiramate: Topiramate 150 mg/day decreased glyburide (5 mg/day) Cmax by 22% and AUC24 by 25%; metabolites M1 and M2 AUC reduced by 13% and 15% and Cmax by 18% and 25%; topiramate pharmacokinetics were unaffected.
Read the label’s full interactions text

Drug Interactions The hypoglycemic action of sulfonylureas may be potentiated by certain drugs including non-steroidal anti-inflammatory agents and other drugs that are highly protein bound, salicylates, sulfonamides, chloramphenicol, probenecid, coumarins, monoamine oxidase inhibitors, and beta adrenergic blocking agents. When such drugs are administered to a patient receiving glyburide tablets the patient should be observed closely for hypoglycemia. When such drugs are withdrawn from a patient receiving glyburide tablets the patient should be observed closely for loss of control. An increased risk of liver enzyme elevations was observed in patients receiving glyburide concomitantly with bosentan. Therefore concomitant administration of glyburide tablets and bosentan is contraindicated. Certain drugs tend to produce hyperglycemia and may lead to loss of control. These drugs include the thiazides and other diuretics, corticosteroids, phenothiazines, thyroid products, estrogens, oral contraceptives, phenytoin, nicotinic acid, sympathomimetics, calcium channel blocking drugs, and isoniazid. When such drugs are administered to a patient receiving glyburide tablets, the patient should be closely observed for loss of control. When such drugs are withdrawn from a patient receiving glyburide tablets, the patient should be observed closely for hypoglycemia. A possible interaction between glyburide and ciprofloxacin, a fluoroquinolone antibiotic, has been reported, resulting in a potentiation of the hypoglycemic action of glyburide. The mechanism for this interaction is not known. A potential interaction between oral miconazole and oral hypoglycemic agents leading to severe hypoglycemia has been reported. Whether this interaction also occurs with the intravenous, topical or vaginal preparations of miconazole is not known. Metformin In a single-dose interaction study in NIDDM subjects, decreases in glyburide AUC and C max were observed, but were highly variable.

Before taking Glyburide

▾
  • Do not use if allergic to glyburide, or if you have type 1 diabetes or diabetic ketoacidosis.
  • Do not use with bosentan.
  • Tell your prescriber about any sulfa allergy.
  • Not recommended in pregnancy or for children.
  • Older, frail or malnourished people, and those with kidney or liver problems, need conservative dosing.

Glyburide overdose

▾

Too much glyburide can cause low blood sugar. Mild symptoms are treated with oral glucose and changes to the dose or meals. Severe cases with coma or seizure are emergencies needing immediate hospital care, and monitoring continues for 24 to 48 hours because low blood sugar can return.

What Glyburide does in the body

▾

Glyburide lowers blood sugar by stimulating insulin release from the pancreas. Its blood sugar-lowering effect lasts about 24 hours after a morning dose. It also causes a mild increase in urine output.

How your body processes Glyburide

▾

Glyburide is absorbed within an hour and peaks in about 2 to 3 hours. Its half-life is about 4 hours. The body breaks it down into weakly active metabolites. These leave the body about equally through bile and urine.

How to store Glyburide

▾

Store at 20º to 25ºC (68º to 77ºF); excursions permitted between 15º to 30ºC (59º to 86ºF) Dispensed in well closed containers with safety closures.

Glyburide: pharmacist answers to common questions

Quick, plain-English answers to the questions patients ask most about Glyburide — the kind of thing our pharmacy team would talk through with you at the counter.

What is glyburide for?

▾
It helps control blood sugar in adults with type 2 diabetes. It works alongside healthy eating and exercise, not in place of them.

How and when should I take it?

▾
Take it by mouth, usually with breakfast or your first main meal. Many people take it once a day, but some split it into two doses. Follow your prescriber's directions and the pharmacy label.

What is the biggest side effect to watch for?

▾
Low blood sugar. Skipping meals or not following your plan can bring it on. If you get confusion, seizures or pass out, that's an emergency and you need immediate care.

Are there medicines I should avoid with it?

▾
Yes. Bosentan must not be taken with glyburide. Many others, including NSAIDs, some antibiotics and steroids, can push your blood sugar too low or too high. Always check with me before starting anything new.

Can I take it if I'm pregnant or if my child has diabetes?

▾
It is not recommended in pregnancy or for children. Talk with your prescriber about other options.

What if I take a cholesterol drug like colesevelam?

▾
Colesevelam reduces how much glyburide your body absorbs. Take glyburide at least 4 hours before colesevelam.

Is Glyburide available over the counter?

▾
No. Glyburide is a prescription medicine: every Glyburide product listed with the FDA is prescription only, so it is not sold over the counter. Your prescriber decides whether it is appropriate for you, and your pharmacist dispenses it.

When was Glyburide first available?

▾
The earliest FDA record we hold for Glyburide is from 1984: its first approval in Drugs@FDA or its earliest product listing in the NDC Directory, whichever is older. Many older medicines were in use before their first formal FDA approval, so this is the earliest date on record, not necessarily when Glyburide was first used.

Who makes Glyburide?

▾
15 companies currently list Glyburide products in the FDA's NDC Directory, including Teva Pharmaceuticals USA, Inc., NuCare Pharmaceuticals,Inc., A-S Medication Solutions. That count includes repackagers and distributors as well as manufacturers (companies that sell only the raw ingredient are not counted), so fewer companies actually make it; the label on your bottle names the one that supplied yours.

How this page is built

HelloPharmacist combines public FDA and NLM records and does not author the underlying clinical facts. The plain-language sections are written with AI from the FDA-approved label text and reviewed by our pharmacy team before publication. TEVA Pharmaceuticals USA Inc is the representative DailyMed label linked for verification and dates. This is general education, not medical advice: always talk to your doctor or pharmacist about your own medicines. How we build and review drug pages →
