Glynase PresTab (micronized glyburide) is an oral blood-glucose-lowering drug used to treat type 2 diabetes (non-insulin dependent). It is not for treating type 1 diabetes. This medication is available in generic form. Common side effects include nausea, heartburn, feeling full, joint or muscle pain, blurred vision, mild itching or skin rash.

The suggested starting dose of Glynase PresTab is 1.5 to 3 mg daily, administered with breakfast or the first main meal. Glynase PresTab may interact with blood thinners, cyclosporine, disopyramide, fluconazole, ketoconazole, fluoxetine, rifampin, ACE inhibitors, antibiotics, albuterol, clonidine, reserpine, or beta-blockers. Hyperglycemia (high blood sugar) may result if you take Glynase with: isoniazid, diuretics, steroids, phenothiazines, thyroid medicines, birth control pills and other hormones, heart or blood pressure medications, seizure medicines, and diet pills or medicines to treat asthma, colds or allergies. Hypoglycemia (low blood sugar) may result if you take Glynase with: clarithromycin, exenatide, probenecid, heart or blood pressure medications, nonsteroidal anti-inflammatory drugs (NSAIDs), aspirin or other salicylates, sulfa drugs, monoamine oxidase inhibitors (MAOIs), or other oral diabetes medications. Tell your doctor all medications and supplements you use. During pregnancy, Glynase PresTab should be used only if prescribed. It is unknown if this drug will harm a fetus.

(Adverse Reactions)

SIDE EFFECTS

Hypoglycemia

See PRECAUTIONS and OVERDOSAGE Sections.

Gastrointestinal Reactions

Cholestatic jaundice and hepatitis may occur rarely which may progress to liver failure; GLYNASE PresTab (micronized glyburide tablets) Tablets should be discontinued if this occurs.

Liver function abnormalities, including isolated transaminase elevations, have been reported.

Gastrointestinal disturbances, eg, nausea, epigastric fullness, and heartburn are the most common reactions, having occurred in 1.8% of treated patients during clinical trials. They tend to be dose related and may disappear when dosage is reduced.

Dermatologic Reactions

Allergic skin reactions, eg, pruritus, erythema, urticaria, and morbilliform or maculopapular eruptions occurred in 1.5% of treated patients during clinical trials. These may be transient and may disappear despite continued use of glyburide. If skin reactions persist, the drug should be discontinued.

Porphyria cutanea tarda and photosensitivity reactions have been reported with sulfonylureas.

Hematologic Reactions

Leukopenia, agranulocytosis, thrombocytopenia, hemolytic anemia (see PRECAUTIONS), aplastic anemia, and pancytopenia have been reported with sulfonylureas.

Metabolic Reactions

Hepatic porphyria and disulfiram-like reactions have been reported with sulfonylureas; however, hepatic porphyria has not been reported with glyburide and disulfiram-like reactions have been reported very rarely.

Cases of hyponatremia have been reported with glyburide and all other sulfonylureas, most often in patients who are on other medications or have medical conditions known to cause hyponatremia or increase release of antidiuretic hormone. The syndrome of inappropriate antidiuretic hormone (SIADH) secretion has been reported with certain other sulfonylureas, and it has been suggested that these sulfonylureas may augment the peripheral (antidiuretic) action of ADH and/or increase release of ADH.

Other Reactions

Changes in accommodation and/or blurred vision have been reported with glyburide and other sulfonylureas. These are thought to be related to fluctuation in glucose levels.

In addition to dermatologic reactions, allergic reactions such as angioedema, arthralgia, myalgia and vasculitis have been reported.
