Dulcolax tablets are laxatives that use an ingredient called bisacodyl to relieve constipation. Take 1 – 2 tablets before you go to bed at night and they’ll get to work as you sleep, letting you see results in 6 – 12 hours. If you’re an adult suffering from short-term constipation, Dulcolax could be the perfect way to help you get regular again. What is constipation?

Constipation is a normal condition that happens to all of us at least once. When you have constipation it means that you won’t be able to poo for a few days or may find that your poo is harder, larger, or lumpier than usual, making it more difficult to pass. Constipation will usually pass, but you may want to try taking a laxative to help get things moving and make some lifestyle changes that can help you get back to normal. Some of the most common causes of constipation include:
Not getting enough fiber in your diet
Not drinking enough fluids
Not being active or not exercising enough
A change in your diet or daily routine
Side effects of some medications, including codeine or co-codamol
Ignoring the urge to poo when you need to

How will the bisacodyl in Dulcolax tablets relieve my constipation?
Dulcolax tablets each contains 5mg of an active ingredient called bisacodyl, which is a type of medication called a stimulant laxative. Stimulant laxatives work by stimulating the muscles in your bowel, helping to move poo through your bowel so it can be passed more easily. This helps to relieve your constipation and encourages your bowel movements to return to regularity.

Can I use this laxative if I’m pregnant?
Constipation happens a lot during pregnancy, so many pregnant women look for constipation relief. However, you should always speak to your doctor or pharmacist before taking Dulcolax or any other medication during your pregnancy or while you’re breastfeeding. Some medications won’t be right for you or your baby at this time, so it’s best to listen to a professional who will be able to recommend some lifestyle changes and a suitable laxative if necessary.

Can I use this product if I’m taking other medication?
If you’re taking any other medication you should speak to your doctor or pharmacist before taking Dulcolax. This especially applies if you’re already taking:
Diuretics, also known as water tablets, e.g. bendrofluazide or furosemide
Steroid medications, e.g. prednisolone
Any other laxatives
Antacids or proton pump inhibitors, which are used for acid reflux and heartburn

How to take these laxative tablets
Take 1 – 2 Dulcolax tablets before you go to bed at night. When you first begin to take these tablets you should start with 1 a night and increase to 2 if necessary. When your regularity has returned to normal you can stop taking the tablets. Swallow the tablets whole with a sip of water or another cool drink. Do not drink milk or similar drinks with these tablets or within an hour of taking Dulcolax. Do not take these tablets for more than 5 days, if you haven’t had a bowel movement after this time or find that you need to take laxatives every day, you should speak to your doctor or pharmacist.
