Repaglinide is a meglitinide medication that regulates blood glucose by stimulating insulin release from the pancreas.
Repaglinide is an oral medication that belongs to the meglitinide class of blood-sugar-lowering agents. It is designed to help the body control glucose levels after meals. The active ingredient appears in several products, the most common being the brand name Prandin.
In Hong Kong, the primary product containing repaglinide is Prandin tablets. Prandin is available in two strengths, 0.5 mg and 1 mg, and is supplied as a film-coated tablet. Generic versions may also be dispensed under the name “repaglinide” in pharmacies, offering the same ingredient without a brand label. These tablets are taken by mouth and are stored at room temperature away from moisture.
Repaglinide is used to manage high blood sugar in people with type 2 diabetes mellitus. It works best when meals are regular and can be part of a broader plan that includes diet and exercise. The medication is typically considered when lifestyle changes alone do not keep glucose levels within the target range. While its main purpose is to lower post-meal blood sugar, doctors may also prescribe it for individuals who need a flexible dosing schedule that matches their eating patterns.
Repaglinide encourages the pancreas to release more insulin, but only for a short period after a meal. By increasing insulin at the right moment, it helps move glucose from the bloodstream into cells where it can be used for energy. The effect begins quickly, usually within 15-30 minutes, and lasts for a few hours, covering the typical rise in blood sugar after eating.
Most people who use repaglinide notice only mild, temporary reactions. These can include a feeling of nausea, mild headache, or a slight upset stomach. Skin irritation or a mild rash may also occur. The symptoms usually resolve on their own and do not require special treatment.
Rarely, repaglinide can cause more severe problems. If you experience difficulty breathing, swelling of the face or lips, or a fast, irregular heartbeat, seek medical help right away. These signs may indicate an allergic reaction or a significant drop in blood sugar that needs urgent attention.
Individuals with a history of severe liver disease, kidney impairment, or a known allergy to repaglinide should discuss alternatives with their healthcare provider. Pregnant or breastfeeding women are generally advised to avoid repaglinide unless a specialist determines that the benefit outweighs any risk. People who have experienced low blood sugar episodes in the past should also use the drug with care.
Repaglinide may interact with other medicines that affect blood sugar, such as certain insulin secretagogues or high-dose corticosteroids. Alcohol can increase the risk of low blood sugar, especially when taken with a meal. Some foods high in fat can slow the drug’s absorption, potentially reducing its effectiveness. Always refer to the specific product’s information page for a complete interaction list.
Store repaglinide tablets in a dry place at ordinary room temperature, away from direct sunlight. The treatment period can differ; some people use it for a few weeks while others continue for many months, depending on the doctor’s plan. Because each product may have its own instructions, be sure to read the label that comes with your specific medication. For detailed usage, dosing, and administration, refer to your particular medication’s information.
