What are Dulcolax tablets?

Dulcolax tablets are laxatives that use an ingredient called bisacodyl to relieve your 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 fibre 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 cocodamol

  • Pregnancy

  • Ignoring the urge to poo when you need to

How will the bisacodyl in Dulcolax tablets relieve my constipation?

Dulcolax tablets each contain 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.

When should this product not be used?

Dulcolax tablets are not suitable for children under the age of 18. Do not take these tablets if you’re allergic to bisacodyl or any of the other listed ingredients. Do not use these tablets if you:

  • Are intolerant to some sugars, as this product contains small amounts of lactose and sucrose

  • Have severe dehydration

  • Have a blockage in the intestine, also known as ileus

  • Have a serious abdominal condition, e.g. appendicitis

  • Have severe abdominal pain, feel sick, and are being sick

  • Have a blocked bowel (intestinal obstruction)

  • Have inflammation of the bowel

Does Dulcolax have any side effects?

Like all medications, Dulcolax tablets can have side effects, although not everyone will experience them. These side effects include symptoms of a severe allergic reaction, which will require immediate medical attention:

  • Swelling of the face, eyes, mouth, tongue, and throat

  • Difficulty breathing or swallowing

  • Dizziness

Other side effects you may experience include:

  • Colitis, which causes abdominal pain and diarrhoea

  • Dehydration

  • Allergic reactions, e.g. skin rash

  • Fainting

  • Blood in your poo

  • Being sick

  • Abdominal (stomach) discomfort

  • Discomfort inside and around your back passage

  • Dizziness

  • Abdominal cramps or pain

  • Diarrhoea

  • Feeling sick

If you experience these or any other side effects while using this product you should speak to your doctor or pharmacist. For more information about reporting the side effects of medication, please see the MHRA’s Yellow Card Scheme.

Can I use laxatives for weight loss?

Laxatives like Dulcolax tablets can not be used to help with weight loss. Some people believe that taking laxatives can help to reduce the number of calories absorbed from your food, but that simply isn’t true. Misusing laxatives in this way can seriously damage your health, causing issues like severe dehydration or problems with your intestinal function. If you’re at all concerned about your weight, we’d recommend speaking to your doctor, practice nurse, or pharmacist for advice.
