How to take or use bisacodyl
How to take tablets
Take bisacodyl tablets once a day just before bedtime.
You can take them with or without food. Swallow tablets whole with water. Do not take them with milk.
Do not take bisacodyl tablets at the same time as:
- dairy products such as milk, cheese or yoghurt
- indigestion remedies (antacids)
- medicines to reduce stomach acid (like proton pump inhibitors such as omeprazole or pantoprazole)
Leave a gap of 1 hour between taking any of these and taking your bisacodyl tablets. This is because they will stop the medicine working properly.
How to use suppositories
Read the instructions in the leaflet inside the package. They will explain how to use the suppository.
Take the wrapping off and push a suppository gently into your bottom (anus).
Suppositories work quickly (usually between 10 and 45 minutes), so use it when you are near a toilet.
