About docusate - Brand names: Dulcoease, Dioctyl, Docusol, Norgalax

Docusate is a type of medicine called a laxative. It helps to soften your poo and makes it easier for you to go to the toilet if you have problems pooing (constipation).

Docusate may help you if:

  • your poos are dry and it makes it difficult for you to poo
  • you have piles (haemorrhoids)
  • you have a tear in the lining of your intestine, near your anus (anal fissure)
  • you're going to have a stomach x-ray as it can help you empty your bowels beforehand

Docusate comes as capsules and as a liquid that you swallow. It also comes as an enema. This is a tube of liquid medicine that you squeeze into your anus (bottom).

Docusate is available on prescription and to buy from pharmacies.

Key facts

  • Docusate capsules and liquid take 1 to 3 days to work.
  • Side effects can include feeling sick (nausea), stomach cramps and diarrhoea.
  • Docusate enemas usually work within 20 minutes, so it's best to stay close to a toilet.
  • Do not use a docusate enema if you have piles (haemorrhoids) or a tear near your anus (anal fissure).
  • Only give docusate to a child under 12 years old if a doctor prescribes it or a pharmacist recommends it.
  • Do not take docusate for more than 5 days, unless it's prescribed by a doctor. Talk to a doctor if you still have constipation after 5 days.
