How to take risperidone Before starting this treatment, read the manufacturer's printed information leaflet from inside the pack. Take risperidone exactly as your doctor has told you. It is usually taken once or twice a day. It is not important whether you take your doses before, with or after meals. If you have been given risperidone orodispersible tablets, peel open the packaging, remove the tablet from the blister and then place it on your tongue to dissolve. Do not try pushing the tablet through the blister of the packaging as it may crumble. If you have been given risperidone liquid you can take your dose added to any non-alcoholic drink except tea. Make sure you understand how to use the dose syringe (pipette) to measure out the dose which is correct for you. If you are unsure about this, ask your pharmacist to show you. Try to take risperidone at the same times each day to avoid missing any doses. If you do forget to take a dose, take it as soon as you remember unless it is nearly time for your next dose, in which case leave out the missed dose. Do not take two doses together to make up for a forgotten dose. Do not stop taking risperidone unless your doctor tells you to do so. Stopping treatment suddenly can cause problems and your doctor will probably want you to reduce your dose gradually if this is necessary.
