This information is written in simple words to help you understand this product. It does not replace advice from your doctor or pharmacist.
Read these points before you start. If any of them apply to you, talk to your doctor or pharmacist first.

- It is for short-term use. Do not use it for more than 5 days without talking to a doctor.
- Do not take it within 1 hour of milk, antacids or acid-lowering medicines. They can dissolve the coating too early and irritate the stomach.

- QHow fast does Dulcolax work?
- A
Tablets usually work in 6 to 12 hours. That is why they are taken at bedtime.

No. Regular use can make the bowel rely on it. See your doctor if you need a laxative for more than a few days.
- QWhy not take Dulcolax with milk?

Milk can dissolve the tablet's coating in the stomach, causing stomach irritation.
