1. What Dioctyl is for

Dioctyl is one of a group of medicines called ‘laxatives’. They are usually taken to prevent and treat constipation that has lasted for a long time.

Dioctyl may also be taken during certain types of stomach X-rays, or to help you go to the toilet if you have piles (haemorrhoids).

2. Before you take Dioctyl

Do not take Dioctyl if:

  • You are allergic to docusate sodium, or to any of the other ingredients in Dioctyl (see section 6)
  • You are suffering from stomach pains
  • You are feeling sick, or have been sick in the last 24 hours
  • You have a blocked bowel (intestinal obstruction)
  • You have been told you are unable to take a sugar called fructose. Dioctyl contains sorbitol and is therefore unsuitable for you
  • You are a child under 12 years old.

If any of the above applies to you talk to your doctor or pharmacist.

Check with your doctor before taking Dioctyl if:

  • You need to take a laxative every day
  • You have regular or constant stomach pain.

Taking Dioctyl with food and drink

Pregnancy and breast-feeding

Warnings about the ingredients in Dioctyl

  • Dioctyl contains sorbitol and is unsuitable for people who are unable to take a sugar called fructose. This rare condition will have been passed down from previous generations of your family.

Tell your pharmacist before taking this medicine if either of the above statements applies to you.
