Glucobay 25mg Tablet 10'S

Introduction About GLUCOBAY 25MG TABLET

Glucobay 25mg Tablet is commonly prescribed to support blood sugar management in adults with type 2 diabetes mellitus (non-insulin dependent diabetes) when diet alone or combined with other glucose-lowering medications does not achieve sufficient control. It contains Acarbose, an anti-diabetic agent classified as an alpha-glucosidase inhibitor.

Acarbose functions by slowing the digestion and absorption of carbohydrates in the small intestine, which helps moderate the rise in blood sugar levels after meals. By delaying carbohydrate breakdown, it contributes to maintaining balanced post-meal glucose levels. Glucobay 25mg Tablet is often used alongside other diabetes medicines as part of a comprehensive care plan to help sustain optimal blood glucose stability.

Glucobay 25mg Tablet should be taken just before or along with the first few bites of your meal. Your doctor will determine the appropriate dose and frequency to help maintain healthy blood sugar levels. The dosage may be gradually adjusted to achieve optimal blood glucose control. It is important not to stop taking the medication without consulting your healthcare provider, as discontinuation could lead to elevated blood sugar levels and increase the risk of serious complications such as kidney issues and vision problems.

This medicine is part of a comprehensive care program that also includes a balanced diet, regular physical activity, and weight management, as recommended by your healthcare provider. Regular monitoring of your blood sugar levels is essential while using this medication. It helps track how well your blood glucose is maintained, enabling informed adjustments to your overall management plan in collaboration with your doctor.

Common side effects of this medicine include gastrointestinal discomfort, flatulence, diarrhea, indigestion and bloating. If these symptoms persist or cause significant discomfort, it is important to consult your healthcare provider. Glucobay 25mg Tablet alone does not typically cause low blood sugar (hypoglycemia). However, when used with other diabetes medications such as insulin or sulphonylureas, it may increase the risk of hypoglycemia. In such cases, managing low blood sugar requires taking plain glucose, as regular sugar sources might not effectively raise blood glucose levels during Glucobay usage.

Before starting Glucobay 25mg Tablet, inform your doctor if you have any kidney or liver conditions. Avoid using this medicine if you have ulceration or inflammation in the bowel, such as ulcerative colitis or Crohn’s disease. Pregnant or breastfeeding women should consult their healthcare provider prior to use. Be sure to disclose all other medications you are taking to ensure safe use. Limit alcohol consumption while taking this medicine, as excessive intake may increase the risk of low blood sugar (hypoglycemia).
