Product overview
About Dulcolax Adult 5mg Tablets
Dulcolax is the overnight constipation answer: bisacodyl 5mg in a gastro-resistant tablet that passes the stomach untouched and stimulates the bowel where it matters — taken at bedtime, it works in 6–12 hours for morning relief. Effective short-term relief from occasional constipation, 20 tablets.
How a stimulant laxative works
Bisacodyl nudges the bowel muscle back into action and draws water into the stool — direct treatment for a system that's stalled, rather than bulking agents that need days. The gastro-resistant coating is why the tablet must be swallowed whole: crushed or chewed, it releases too early and cramps.
How to take
Adults: start with 1 tablet before bed — step up to 2 only if needed. Swallow whole with water; avoid milk, antacids or indigestion remedies within an hour (they break the coating early). Short-term use only: if you need it beyond a few days, that's a pharmacist conversation.
Constipation deserves fixing, not managing
Fibre, fluids and movement fix most constipation long-term; a stimulant laxative is the reset button. As the pack itself says: it does not help with weight loss, and overuse can be harmful — chronic laxative use makes bowels lazier, not better.

Frequently asked questions
How long does Dulcolax take to work?
6–12 hours — which is the point of taking it at bedtime: it works while you sleep and delivers in the morning.
Why must I swallow it whole?
The gastro-resistant coating carries the bisacodyl past your stomach. Crushing or chewing — or taking milk or antacids within an hour — releases it early and trades relief for cramps.
How often can I use laxatives?
Occasionally, for a few days at most. Needing them regularly means the constipation itself needs looking at — fibre, fluids, movement, medication review — with a pharmacist or GP.
Do laxatives help with weight loss?
No — the pack itself warns they don't. They remove water and stool, not calories, and misusing them for weight is genuinely dangerous.
