Product introduction

AC 50mg 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. AC 50mg 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).

This contributes to better diabetes control, reduces the risk of complications like nerve damage or heart issues, and helps individuals feel more energetic and in control of their health.

Frequently asked questions

Does AC 50mg Tablet cause hypoglycemia?

Although AC 50mg Tablet has a glucose-lowering effect, it does not cause hypoglycemia. However, blood sugar levels may fall into the hypoglycemic range when given along with other antidiabetic medicines or insulin. If this occurs, consult your doctor, who may modify your dose accordingly.

Why does AC 50mg Tablet cause flatulence?

AC 50mg Tablet blocks the digestion of carbohydrates, which causes the accumulation of undigested carbohydrates in the colon. Bacterial fermentation of the accumulated carbohydrates causes intestinal gas, leading to flatulence and abdominal pain.

Can AC 50mg Tablet cause diarrhea?

Yes, diarrhea is a common side effect of AC 50mg Tablet. However, it does not affect everybody. Any food containing carbohydrates, such as household sugar (cane sugar), can cause diarrhea and severe abdominal pain. If diarrhea persists or becomes severe, contact your doctor immediately.

What if I forget to take AC 50mg Tablet?

If you forget to take a dose of AC 50mg Tablet, do not take the missed dose between meals. Wait for the scheduled dose and meal, and continue taking your tablets as prescribed. Do not take the dose twice to make up for your forgotten tablets.

What will happen if more than the recommended dose of AC 50mg Tablet is taken?

Who should not take AC 50mg Tablet?
