Why is this medication prescribed?
Paliperidone is used to treat the symptoms of schizophrenia (a mental illness that causes disturbed or unusual thinking, loss of interest in life, and strong or inappropriate emotions). Paliperidone is in a class of medications called atypical antipsychotics. It works by changing the activity of certain natural substances in the brain.
How should this medicine be used?
Paliperidone comes as an extended-release (long-acting) tablet to take by mouth. It is usually taken once a day in the morning with or without food. Take paliperidone at around the same time 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 paliperidone exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Swallow the tablets whole with plenty of water or other liquid. Do not split, chew, or crush the tablets. Tell your doctor if you cannot swallow tablets. Your doctor will probably prescribe another medication to treat your condition.
Talk to your doctor about how you are feeling during your treatment. If your symptoms are still bothersome, your doctor may gradually increase your dose, not more often than once every 5 days.
Paliperidone controls the symptoms of schizophrenia but does not cure the condition. Continue to take paliperidone even if you feel well. Do not stop taking paliperidone without talking to your doctor.
What are the precautions to be followed?
Before taking paliperidone,
tell your doctor and pharmacist if you are allergic to paliperidone, risperidone (Risperdal), 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; certain antibiotics such as erythromycin (E.E.S., E-Mycin, Erythrocin), gatifloxacin (Tequin) (not available in the United States), moxifloxacin (Avelox), and sparfloxacin (Zagam); certain antipsychotics such as chlopromazine (Sonazine, Thorazine), pimozide (Orap), risperidone (Risperdal) and thioridazine; cisapride (Propulsid); levodopa (in Sinemet, in Stalevo); medications for anxiety, high blood pressure, or seizures; medications for irregular heartbeat such as amiodarone (Cordarone), disopyramide (Norpace), dofetilide (Tikosyn); procainamide (Procanbid, Pronestyl), quinidine (Quinidex), and sotalol (Betapace, Betapace AF); sedatives; sleeping pills; and tranquilizers. Your doctor may need to change the doses of your medications or monitor you carefully for side effects.
tell your doctor if you have or have ever had a prolonged QT interval (a rare heart problem that may cause fainting or irregular heartbeat); slow or irregular heartbeat; a heart attack; low levels of potassium or magnesium in your blood; seizures; a stroke; a head injury; a brain tumor; Parkinson's disease (a disorder of the nervous system that causes difficulties with movement, muscle control, and balance); diabetes; breast cancer; surgery involving the intestines; any condition that causes blockage or narrowing of the esophagus (tube that connects the mouth and stomach), stomach, or intestines such as cystic fibrosis (an inborn disease that causes problems with breathing, digestion, and reproduction), and inflammatory bowel disease (IBD; a group of conditions that cause swelling of the lining of the intestines); and kidney, heart, or liver disease. Also tell your doctor if you drink or have ever drunk large amounts of alcohol and if you use or have ever used street drugs or have overused prescription medications. 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 are pregnant, especially if you are in the last few months of your pregnancy, or if you plan to become pregnant or are breast-feeding. If you become pregnant while taking paliperidone, call your doctor. Paliperidone 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 paliperidone.
you should know that paliperidone may make you drowsy and may cause difficulty with thinking and movement. Do not drive a car or operate machinery until you know how this medication affects you.
you should know that alcohol may add to the drowsiness caused by paliperidone. Do not drink alcoholic beverages while you are taking this medication.
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 may be more likely to develop diabetes than people who do not have schizophrenia, and taking paliperidone or similar medications may increase this risk. Tell your doctor immediately if you have any of the following symptoms while you are taking paliperidone: 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 can cause more serious symptoms, such as dry mouth, nausea and vomiting, shortness of breath, breath that smells fruity, or decreased consciousness, and may become life-threatening if it is not treated at an early stage.
you should know that paliperidone may make it harder for your body to cool down when it gets very hot. Tell your doctor if you plan to exercise or be exposed to extreme heat.
you should know that paliperidone 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 paliperidone or when your dose is increased. To avoid this problem, get out of bed slowly, resting your feet on the floor for a few minutes before standing up.
