Dulcolax® Suppositories are what we call a 'stimulant laxative'. It gives you relief from occasional constipation symptoms - and fast - working in about 20 minutes (Usual range 10 to 30 minutes).
 
With its dual action, Dulcolax® Suppositories transport water and salt into your gut to hydrate poo and make it easier to pass. The suppositories also stimulate the bowel muscles, causing your intestines to contract. These two actions combined accelerate the transit of poo through your colon, so you can start to feel free inside and out.
