Side Effects

Quick Answer

The most common side effects of Acarbose are GI effects — gas (flatulence), bloating, abdominal discomfort, and diarrhoea. These effects are dose-dependent and are considerably reduced with slow titration. Serious side effects are rare but hepatotoxicity (liver damage) is possible — see a doctor immediately for jaundice.

Side Effects at a Glance

Common

Gas / flatulence (a significant issue — very common, dose-dependent)
Abdominal bloating / distension
Diarrhoea
Abdominal pain / cramps

Serious — See a Doctor

Hepatotoxicity (rare — especially at doses >100mg TID; jaundice, LFT elevation)
Severe GI complications (rare — bowel obstruction exacerbation if sub-ileus)

When to See a Doctor Immediately

Jaundice — yellowing of the eyes or skin
Severe abdominal pain + bloating + vomiting + absence of bowel movement (sub-ileus — STOP the drug)
Severe hypoglycaemia (combination with SU/insulin) — use GLUCOSE, not sucrose

Acarbose Tablet Side Effects

Acarbose (Glucobay) GI side effects are very common — they are a significant challenge for patient acceptance in Pakistan. However, they improve significantly with slow titration and dietary adjustment.

Common Side Effects (GI Effects)

Gas / flatulence
Abdominal bloating / distension
Diarrhoea
Abdominal pain / cramps

Why it occurs: Undigested carbohydrates reach the colon, where bacteria ferment them → gas.

Solution: Start at a low dose, increase slowly, and reduce refined carbohydrates (white flour, sugar) in the diet.

Serious Side Effects (Rare)

Hepatotoxicity (liver damage) — jaundice, LFT elevation — rare, at high doses
Severe GI complications — rare — risk of bowel obstruction exacerbation if pre-existing condition is present

When to See a Doctor

Jaundice
Severe abdominal pain + bloating + no bowel movement (sub-ileus — STOP drug immediately)
Severe hypoglycaemia

Side Effects Summary Table

Type	Side Effect	Action
Common	Gas / flatulence	Slow titration, reduce refined carbs
Common	Bloating / diarrhoea	Dietary adjustment + slow titration
Serious (rare)	Jaundice (hepatotoxicity)	Stop drug — see doctor immediately
Emergency	Hypoglycaemia (with SU/insulin)	Use GLUCOSE only — not table sugar

Frequently Asked Questions

Acarbose se itni gas kyun banti hai?

Acarbose slows carbohydrate digestion. These undigested carbohydrates reach the colon where bacteria ferment them — causing gas and bloating. Starting at a low dose and reducing refined carbohydrates significantly reduces this problem.

Acarbose ki GI side effects kab theek hoti hain?

With slow titration and dietary adjustment (reducing refined carbs), GI side effects improve week by week. Most patients adapt within weeks. Patience and slow dose escalation are necessary.

Acarbose se liver damage ho sakta hai?

Rarely — particularly at high doses (>100mg TID) and in Asian patients, hepatotoxicity has been reported. LFTs (liver function tests) must be monitored during long courses or at high doses. For jaundice, see a doctor immediately and discontinue the medicine.

Acarbose ke saath hypoglycaemia mein kya karein?

Use GLUCOSE — dextrose tablets, glucose juice, or honey. Table sugar (sucrose), sweets, or ordinary confectionery will NOT work — acarbose blocks sucrose digestion. This is a critical safety point that patients must always remember.

Side effects report kaise karein?
