Glibenclamide Medications

Glibenclamide Info

What is Glibenclamide?

Glibenclamide (also known as glyburide) belongs to the class of medicines called sulfonylureas. Its main purpose is to help lower blood sugar in people with diabetes. You will find glibenclamide as the active ingredient in products such as Micronase and Glyburide that are marketed in Hong Kong.

Medications with Glibenclamide

In Hong Kong, glibenclamide is available in a few common brands:

• Micronase - supplied as oral tablets, usually in strengths of 2.5 mg, 5 mg, and 10 mg.
• Glyburide - offered as generic tablets, also in the same strength range.

Both brands may appear in plain-generic form or combined with other diabetes agents (for example, a fixed-dose tablet with metformin). The tablets are taken by mouth and are stored at room temperature, away from moisture. Availability can vary between pharmacies, but both products are approved by the Hong Kong health authority, the Health Products and Food Safety Authority (HPFSA).

What Does Glibenclamide Treat?

Glibenclamide is primarily used for:

• Type 2 diabetes mellitus - helps the pancreas release more insulin, which moves excess glucose from the blood into the body’s cells.
• Gestational diabetes (when deemed appropriate by a specialist) - sometimes used under close supervision during pregnancy.
• Secondary hyperglycaemia caused by certain medical conditions or medications, when other options are unsuitable.

People with type 2 diabetes often need additional lifestyle measures, such as a balanced diet and regular activity, alongside any medication.

How Glibenclamide Works

Glibenclamide encourages the pancreas to release more insulin, a hormone that lowers blood glucose. By boosting this natural insulin release, the drug helps bring high blood sugar levels back toward the normal range. Most users notice a reduction in blood glucose within a few hours after taking a tablet, although the full effect may develop over several days as the body adjusts.

Safety Information

Common Side Effects

• Mild stomach upset or nausea
• Headache
• Light-headedness, especially if blood sugar falls too low

These effects are usually short-lived and may improve as the body becomes accustomed to the medication.

Serious Reactions

• Signs of severe low blood sugar (hypoglycaemia), such as confusion, trembling, or loss of consciousness
• Allergic reactions that cause swelling of the face, lips, or throat, or a rash that spreads quickly

If any of these symptoms appear, seek urgent medical help.

Who Should Be Cautious

• People with a known allergy to sulfonylureas
• Individuals with severe kidney or liver disease, as these conditions can change how the drug works in the body
• Pregnant or breastfeeding persons should only use glibenclamide if a healthcare professional has specifically approved it

Interaction Awareness

• Other diabetes medicines may increase the risk of low blood sugar when taken together.
• Certain antibiotics, antifungal agents, and blood pressure drugs can affect blood glucose control.
• Alcohol may heighten the chance of hypoglycaemia, especially if consumed on an empty stomach.

What to Know Before Using

Store glibenclamide tablets in a cool, dry place away from direct sunlight. The medication is generally intended for short-term control of blood sugar spikes, but some patients may need it for longer periods as directed by their prescriber. Always read the label that comes with your particular product, as strengths and extra ingredients can differ between Micronase and Glyburide.

For detailed usage, dosing, and administration, refer to your specific medication’s information.
