Bisacodyl Suppositories are for use in adults and children over 10 years of age only.

How to use it

To remove suppository, tear one from the strip along the perforation, then peel it from the container by pulling apart the tabs at the top of the suppository. If suppository is soft, place in refrigerator for 30 minutes prior to use.

You may lubricate the tip of the suppository with lubricating jelly before insertion to make insertion easier.

Insert one suppository well up in the rectum (back passage) and allow to remain for 15 to 30 minutes.

Lie on one side and pull up knees. Gently insert suppository, pointed end first, high into the rectum. Onset of action usually between 15 to 60 minutes.

Avoid pushing suppository into faecal matter as this will delay its action.

If you are not sure how to use a suppository, ask your doctor or pharmacist for advice.
