What are Dulcolax Overnight Tablets?

Dulcolax Overnight Relief tablets are laxative tablets that work as you sleep to ease your constipation. Constipation can be very uncomfortable, making you feel bloated and blocked up until you manage to have a bowel movement, and laxative tablets like these can help. If you’re suffering from constipation and need a reliable treatment that can help to get things moving again quickly, Dulcolax Overnight tablets could be the perfect solution for you.


What is constipation?

Constipation is a common condition that simply means you can’t poo. Most people have constipation at least once in their lives and it usually clears up by itself relatively quickly but it has lots of different causes. Some of the most common reasons why people have constipation include:

  • Not getting enough fibre in your diet
  • Being dehydrated
  • A change in your diet or routine
  • Pregnancy
  • Being inactive or not exercising often
  • Resisting the urge to go to the toilet
  • Side effects of some medication, such as codeine


How will Dulcolax 5mg Overnight Tablets help to ease my constipation?

Each Dulcolax Overnight tablet contains 5mg of an active ingredient called bisacodyl. Bisacodyl is a stimulant laxative, which means it works by stimulating the walls of your bowel, helping it to move poo through your system so you can pass it. This process works within 6 - 12 hours, so you can typically take your tablets before you go to bed and have a bowel movement the following morning.


Can I take these laxative tablets if I’m pregnant or breastfeeding?

If you are pregnant or breastfeeding you should speak to your doctor or pharmacies before taking Dulcolax tablets or any other laxatives or medications. Some medications may not be suitable for you during these times, but a medical professional can help you to choose a treatment that’s right for you and your baby.


Can I take 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 Overnight tablets. This especially applies if you are already taking:

  • Water tablets, which are also known as diuretics, such as bendrofluazide or furosemide (also known as frusemide)
  • Steroid medicines, such as prednisolone
  • Any other laxatives


Can I drive after taking these tablets?

Some people may find that they feel dizzy after taking Dulcolax laxative tablets. If this happens to you, you should not attempt to drive or operate any tools or machinery until the sensation has passed and you are absolutely sure that you are safe to do so.


How to take these tablets

Take 1 - 2 Dulcolax Overnight tablets at night, swallowed whole with a drink of water. If you have never taken laxatives before, start with one tablet and then increase the dosage to 2 if needed. Do not take these tablets every day for more than 5 days, if you find that you do need to take laxatives every day, you should speak to your doctor for advice. Do not drink milk or take antacids or proton pump inhibitors (which are used to reduce excess stomach acid) within an hour of taking these tablets as they will stop this product from working.
