What Are Dulcolax Suppositories?
Dulcolax 10mg Suppositories contain bisacodyl, a trusted stimulant laxative used for the short-term relief of occasional constipation. Unlike oral laxatives, which work through the digestive system over several hours, suppositories act directly in the rectum — which is why they work so much faster.
Bisacodyl works in two ways: it stimulates the muscles of the bowel to increase natural movement, while also helping the bowel retain water to soften the stool and make it easier to pass. Most people experience relief in around 20 minutes, with the usual range being 10 to 30 minutes.
Why Choose a Suppository Over a Tablet or Liquid?
If you need relief quickly — rather than overnight — a suppository is usually the faster option. Oral laxatives need to travel through the digestive system first, typically taking 6–12 hours. A suppository bypasses that process entirely, working directly where it’s needed.
How to Use
- Wash your hands before and after use
- Unwrap the suppository fully
- Insert it into the rectum, pointed end first
- Try to retain it for as long as comfortable to allow it to work
- Relief is usually felt within 10–30 minutes (occasionally up to 45 minutes)
Adults and children over 10 years: One suppository (10mg) as needed.
Suppositories can also be used alongside Dulcolax tablets as part of bowel preparation for medical procedures, but only under medical supervision — speak to your pharmacist or doctor if this applies to you.
Who Should Not Use Dulcolax Suppositories
- Anyone allergic to bisacodyl or any ingredient in the product
- Severe dehydration
- A bowel blockage (ileus) or intestinal obstruction
- A serious abdominal condition such as appendicitis
- Severe abdominal pain with nausea and vomiting
- Acute inflammatory bowel disease
- Anal fissures or ulcerative proctitis with mucosal damage
- Children under 10 years — ask your pharmacist about appropriate lower-strength alternatives
Speak to your pharmacist first if you are pregnant or breastfeeding, or using other laxatives at the same time.
Possible Side Effects
-
Common: Abdominal discomfort, cramping, and a local burning sensation at the site of insertion
-
Uncommon: Diarrhoea, nausea
-
Rare: Rectal bleeding, inflammation of the rectum (proctitis)
If laxatives are needed every day, or if you have persistent abdominal pain or notice blood in your stool, stop use and consult your doctor.
Pharmacist’s Note
“Suppositories are often the right call when someone needs relief that day rather than overnight — they tend to work much faster than tablets or liquid because they act directly in the bowel. The main thing I always check with patients is whether they have any anal fissures or signs of rectal irritation, since suppositories aren’t suitable in that case. If constipation is a regular issue rather than occasional, it’s worth a proper conversation with us rather than relying on suppositories long-term.†Anne Harty Ballyduff Pharmacy
