When Risperidone Should Not Be Used:
You should not use Risperidone if you have had an allergic reaction to risperidone.
How to Use Risperidone:
Tablet, Liquid, Dissolving Tablet
- Your doctor will tell you how much of Risperidone to use and how often. Your dose may need to be changed several times in order to find out what works best for you. Do not use more medicine or use it more often than your doctor tells you to.
- Measure the oral liquid medicine with a marked measuring spoon, oral syringe, or medicine cup. You may mix your dose with water, low-fat milk, coffee, or orange juice. Do not mix with cola or tea.
- If you are using the disintegrating tablet, make sure your hands are dry before you handle the tablet. Do not open the blister pack that contains the tablet until you are ready to take it. Remove the tablet from the blister pack by peeling back the foil, then taking the tablet out. Do not push the tablet through the foil. Place the tablet in your mouth. It should melt quickly. After the tablet has melted, swallow or take a drink of water.
If a dose of Risperidone is missed:
- If you miss a dose or forget to use your medicine, use it as soon as you can. If it is almost time for your next dose, wait until then to use the medicine and skip the missed dose. Do not use extra medicine to make up for a missed dose.
How to Store and Dispose of Risperidone:
- Store the medicine in a closed container at room temperature, away from heat, moisture, and direct light. Do not freeze the oral liquid.
- Ask your pharmacist, doctor, or health caregiver about the best way to dispose of any leftover medicine after you have finished your treatment. You will also need to throw away old medicine after the expiration date has passed.
- Keep all medicine away from children and never share your medicine with anyone.
Drugs and Foods to Avoid While Taking Risperidone:
Ask your doctor or pharmacist before using any other medicine, including over-the-counter medicines, vitamins, and herbal products.
- There are many other medicines that you should not use while you are taking risperidone. Taking risperidone with certain other medicines may be dangerous, even life-threatening. Make sure your doctor and your pharmacist knows about all other medicines you are using.
- Make sure your doctor knows if you are taking carbamazepine (Tegretol®), cimetidine, furosemide (Lasix®), levodopa, fluoxetine (Prozac®), paroxetine (Paxil®), phenobarbital, ranitidine, or valproate (Depakene®, Depakote®). Tell your doctor if you are using clozapine (Clozaril®), quinidine, phenytoin (Dilantin®), or rifampin (Rifadin®). Make sure your doctor knows if you are also using medicine to lower blood pressure. Some blood pressure medicines are atenolol, hydrochlorothiazide (HCTZ), lisinopril, metoprolol, quinapril, Accupril®, Cozaar®, Diovan®, Lotrel®, Norvasc®, Toprol®, and Zestril®.
