How to take risperidone
Follow the instructions in the leaflet that comes with your medicine.
Standard tablets
Swallow your risperidone tablet with a drink of water.
If you need to take half a tablet for your dose or if you have difficulty swallowing the whole tablet, use the score line on the tablet to break it in half.
You can take risperidone tablets with or without food.
Tablets that dissolve in your mouth (orodispersible)
Make sure your hands are dry. Only remove a tablet from the pack when you're ready to take it and put it on your tongue, straight away.
The tablet will begin dissolving within seconds. You can have a drink of water afterwards if you like.
Liquid
Your medicine will come with a syringe, dropper (pipette) or measuring cup to help you to measure out the right dose. If you do not have one, ask your pharmacist for one. Do not use a kitchen spoon as it will not measure the right amount.
You can take risperidone liquid with or without food.
Injections
If you need to have a risperidone injection, you'll usually have it every 2 or 4 weeks at your GP surgery (or from your mental health team).
After you've had an injection, the medicine works for a few weeks. The dose will depend on how well risperidone works for you.
