How do I take/use this medicine?
Take Risperidone exactly as directed by your doctor. Do not take more or less than instructed by your doctor.
You may need to take Risperidone for some time before the full benefits can be felt. Do not be discouraged if you do not feel better soon after taking the medicine. Risperidone must be taken regularly for it to work well.
Do not stop taking Risperidone unless your doctor has decided that you can stop. If Risperidone is stopped suddenly, you may feel unwell or your condition may worsen. When your doctor decides that you do not need Risperidone anymore, he will usually reduce your dose slowly. Follow the doctor's instructions carefully.
You may take Risperidone before or after food. Try to take it at the same time everyday.
Risperidone is available as a tablet, orodispersible tablet or oral liquid.
If you have been given the orodispersible tablet (usually marked as "Quicklet" or "Orodispersible" or "Orally Disintegrating"), remove it from the foil only just before you take it. Do not leave the orodispersible tablet exposed to air. Do not push the orodispersible tablet through the foil as it is fragile and easily broken. Remove the orodispersible tablet with dry hands by peeling the backing off the foil and tipping the tablet onto your dry hands. Place the orodispersible tablet directly on your tongue as soon as it taken out of the foil. The orodispersible tablet will start to melt on the tongue very quickly. Swallow it with or without water. Do not cut, break or crush the orodispersible tablets.
If you have been given the oral liquid, use the pipette (dropper) supplied with each bottle to measure out your dose. Refer to the package insert for directions on how the dropper should be used. The oral liquid can be mixed with a glass of non-alcoholic drink such as water, orange juice, low fat milk or black coffee. Once it is mixed, drink it immediately. Do not mix Risperidone oral liquid with tea or cola (soda).
Always keep your appointments with your doctor so that he will be able to monitor your response to Risperidone.
