Dosage Guide

Quick Answer

Acarbose tablet must be taken WITH THE FIRST BITE OF THE MEAL — not before, not after. Start with a low dose (25mg) and titrate slowly to reduce GI side effects. If a meal is skipped, skip the dose too. Always follow your doctor's prescribed dose and schedule.

Dose at a Glance

Adult Dose

As prescribed — typically start 25mg once daily, titrate slowly

With first bite of each main meal — 2-3 times daily as prescribed

Max: As prescribed by doctor — do not exceed recommended daily dose

Child Dose (Mainly adult use)

Not routinely used in children — consult doctor

As directed

Missed Dose

If you forget the dose and have already eaten, skip that dose — taking it after food does not work. Return to the next prescribed dose. Never take a double dose.

Overdose

Excess dose can cause severe GI symptoms — abdominal pain, bloating, diarrhoea. If overdose is suspected, contact a doctor immediately.

Acarbose Tablet Dosage

Correct timing of Acarbose Tablet is critical — it only works when taken with food. Always follow your doctor's prescription.

Starting dose: As prescribed — typically 25mg once daily
Titration: Slowly increase as prescribed (week by week) to reduce GI side effects

CRITICAL Administration Rule

TAKE WITH THE FIRST BITE OF THE MEAL — exactly with the first bite, not before and not after.

When starting the meal — take Acarbose with the first bite
If the meal is skipped — skip the dose
Only works when taken with carbohydrate-containing meals

Titration Schedule (Slow Start)

To minimise GI side effects:

1. Start at a low dose 2. Slowly increase the dose week by week 3. Reduce refined carbohydrates (white flour, sugar) in the diet

Missed Dose

If a meal has been eaten and the dose was forgotten — SKIP that dose. Take the regular dose at the next meal. Never take a double dose.

Hypoglycaemia Emergency Note

In combination with a sulfonylurea or insulin: if blood sugar drops, use GLUCOSE ONLY (dextrose tablets, glucose juice, honey). Table sugar / sweets / ordinary confectionery will NOT work — Acarbose blocks sucrose absorption.

Frequently Asked Questions

Should Acarbose be taken before or after food?

Neither before nor after — it must be taken WITH THE FIRST BITE of the meal. Enzyme inhibition must coincide with carbohydrate ingestion — only then does it work.

How to reduce the GI side effects of Acarbose?

Start at a low dose (25mg) and slowly increase week by week as the doctor advised. Reduce refined carbohydrates (white flour, sugar) in diet — this will reduce colonic fermentation and gas.

Should Acarbose be taken if a meal is skipped?

No — if a meal is skipped, skip the dose too. Acarbose only works when carbohydrate-containing food is taken with it.

How many times per day should Acarbose be taken?

As per the doctor's prescription — generally three times daily. The starting dose is usually once daily, then titrated.

What to do if hypoglycaemia occurs while on Acarbose?

If taking with a sulfonylurea or insulin and blood sugar drops, use GLUCOSE — dextrose tablets, glucose juice, or honey. Table sugar (sucrose, sweets) will NOT work — Acarbose blocks sucrose digestion.
