Risperdal Oral Solution

Name: Risperdal Oral Solution

How should this medicine be used?

Risperidone comes as a tablet, a solution (liquid), and an orally disintegrating tablet (tablet that dissolves quickly in the mouth) to take by mouth. It is usually taken once or twice a day with or without food. Take risperidone at around the same time(s) every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take risperidone exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Use the dropper provided to measure your dose of risperidone oral solution. You can take the oral solution with water, orange juice, coffee, or low-fat milk. Do not take the solution with tea or cola.

Do not try to push the orally disintegrating tablet through the foil. Instead, use dry hands to peel back the foil packaging. Immediately take out the tablet and place it on your tongue. The tablet will quickly dissolve and can be swallowed with or without liquid. Do not chew or crush the tablet.

Your doctor will probably start you on a low dose of risperidone and gradually increase your dose to allow your body to adjust to the medication.

Risperidone may help control your symptoms but will not cure your condition. It may take several weeks or longer before you feel the full benefit of risperidone. Continue to take risperidone even if you feel well. Do not stop taking risperidone without talking to your doctor. If you suddenly stop taking risperidone, your symptoms may return and your illness may become harder to treat.

What special precautions should I follow?

Before taking risperidone,

  • tell your doctor and pharmacist if you are allergic to risperidone or any other medications.
  • tell your doctor and pharmacist what prescription and nonprescription medications, vitamins, nutritional supplements and herbal products you are taking or plan to take. Be sure to mention any of the following: antidepressants; carbamazepine (Tegretol); cimetidine (Tagamet); clozapine (Clozaril); dopamine agonists such as bromocriptine (Parlodel), cabergoline (Dostinex), levodopa (Dopar, Larodopa), pergolide (Permax), and ropinirole (Requip); medications for anxiety, high blood pressure, or seizures; other medications for mental illness; paroxetine (Paxil); phenobarbital (Luminal, Solfoton); phenytoin (Dilantin); quinidine (Quinaglute, Quinidex); ranitidine (Zantac); rifampin (Rifadin, Rimactane); sedatives; sleeping pills; tranquilizers; and valproic acid (Depakote, Depakene). Your doctor may need to change the doses of your medications or monitor you carefully for side effects.
  • tell your doctor if you use or have ever used street drugs or large amounts of alcohol; if you have ever overused prescription medications; if you have or have ever had Parkinson's disease (PD; a disorder of the nervous system that causes difficulties with movement, muscle control, and balance); dyslipidemia (high cholesterol levels); a low level of white blood cells in your blood or a decrease in white blood cells; difficulty swallowing; trouble keeping your balance; breast cancer; angina (chest pain); irregular heartbeat; high or low blood pressure; heart failure; a heart attack; a stroke; seizures; heart, kidney or liver disease; or if you or anyone in your family has or has ever had diabetes. Also tell your doctor if you have ever had to stop taking a medication for mental illness because of severe side effects. Tell your doctor if you have severe vomiting or diarrhea or signs of dehydration now, or if you develop these symptoms at any time during your treatment.
  • tell your doctor if you are pregnant, especially if you are in the last few months of your pregnancy, or if you plan to become pregnant or are breastfeeding. If you become pregnant while taking risperidone, call your doctor. Risperidone may cause problems in newborns following delivery if it is taken during the last months of pregnancy.
  • if you are having surgery, including dental surgery, tell the doctor or dentist that you are taking risperidone.
  • you should know that risperidone may make you drowsy. Do not drive a car or operate machinery until you know how this medication affects you.
  • you should know that alcohol can add to the drowsiness caused by this medication. Do not drink alcohol while taking risperidone.
  • you should know that you may experience hyperglycemia (increases in your blood sugar) while you are taking this medication, even if you do not already have diabetes. If you have schizophrenia, you are more likely to develop diabetes than people who do not have schizophrenia, and taking risperidone or similar medications may increase this risk. Tell your doctor immediately if you have any of the following symptoms while you are taking risperidone: extreme thirst, frequent urination, extreme hunger, blurred vision, or weakness. It is very important to call your doctor as soon as you have any of these symptoms, because high blood sugar that is not treated can cause a serious condition called ketoacidosis. Ketoacidosis may become life-threatening if it is not treated at an early stage. Symptoms of ketoacidosis include dry mouth, upset stomach and vomiting, shortness of breath, breath that smells fruity, and decreased consciousness.
  • you should know that risperidone may make it harder for your body to cool down when it gets very hot or warm up when it gets very cold. Tell your doctor if you plan to do vigorous exercise or be exposed to extremely high or low temperatures.
  • you should know that risperidone may cause dizziness, lightheadedness, and fainting when you get up too quickly from a lying position. This is more common when you first start taking risperidone. To avoid this problem, get out of bed slowly, resting your feet on the floor for a few minutes before standing up.
  • if you have phenylketonuria (PKU, an inherited condition in which a special diet must be followed to prevent mental retardation), you should know that the orally disintegrating tablets contain phenylalanine.

What special dietary instructions should I follow?

Unless your doctor tells you otherwise, continue your normal diet.

What should I know about storage and disposal of this medication?

Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom). Always store the orally disintegrating tablets in their sealed package, and use them immediately after opening the package. Throw away any medication that is outdated or no longer needed. Talk to your pharmacist about the proper disposal of your medication.

It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org

What other information should I know?

Keep all appointments with your doctor and the laboratory. Your doctor may order certain lab tests to check your body's response to risperidone.

Do not let anyone else take your medication. Ask your pharmacist any questions you have about refilling your prescription.

It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
