Product introduction

Glucobay 50 Tablet should be taken just before or along with the first few bites of the meal. Your doctor will decide the dose and how often you need it to get the right amount to control your blood sugar levels. The dose may be increased gradually. Please do not stop taking it without consulting your doctor. If you do, your blood sugar levels may rise, putting you at risk of serious complications like kidney damage and blindness.

This medicine is only part of a treatment program that should also include a healthy diet, regular exercise, and weight reduction, as advised by your doctor. Monitor your blood sugar levels regularly while taking this medicine.

The most common side effects of this medicine are gastrointestinal discomfort and flatulence. Consult your doctor if these bother you or do not go away. Glucobay 50 Tablet alone does not cause hypoglycemia (low blood sugar levels). However, when used in combination with other diabetes medicines (especially insulin or sulphonylureas), it can lead to hypoglycemia (low blood sugar levels). Such episodes of hypoglycemia should be treated by taking plain glucose as common sugar will not help correct low blood sugar levels if you take this medicine.

Before taking it, let your doctor know if you have kidney or liver problems. Do not take this medicine if you have ulceration or inflammation in the bowel (e.g., ulcerative colitis or Crohn’s disease). Pregnant or breastfeeding women should also consult their doctor before taking it. Please tell your doctor about all the other medicines you are taking to ensure your safety. Avoid excessive alcohol intake while taking this medicine as it may increase the risk of hypoglycemia (low blood sugar levels).
