Uses for paliperidone

Paliperidone is used to treat the symptoms of psychotic (mental) disorders, such as schizophrenia.

This medicine should not be used to treat behavioral problems in older adult patients who have dementia.

This medicine is available only with your doctor's prescription.

Precautions while using paliperidone

It is very important that your doctor check you or your child's progress at regular visits to make sure that this medicine is working properly. Blood and urine tests may be needed to check for any unwanted effects.

This medicine may raise your risk of having a stroke. This is more likely in people who already have heart or blood vessel disease. Check with your doctor right away if you are having confusion, difficulty speaking, slow speech, inability to speak or move the arms, legs, or facial muscles, double vision, or headache.

Check with your doctor right away if you or your child have difficulty breathing, fast heartbeat, high fever, high or low blood pressure, increased sweating, loss of bladder control, seizures, severe muscle stiffness, unusually pale skin, or tiredness. These could be symptoms of a serious condition called neuroleptic malignant syndrome (NMS).

This medicine may cause tardive dyskinesia (a movement disorder). Check with your doctor right away if you or your child have lip smacking or puckering, puffing of the cheeks, rapid or worm-like movements of the tongue, uncontrolled chewing movements, or uncontrolled movements of the arms and legs.

This medicine may increase the amount of sugar in your blood. Check with your doctor right away if you or your child have blurred vision, dry mouth, flushed, dry skin, increased hunger, increased thirst or urination, nausea, sweating, trouble breathing, unexplained weight loss, unusual tiredness or weakness, or vomiting. If you have diabetes, you may notice a change in the results of your urine or blood sugar tests. If you have any questions, check with your doctor.

Dizziness, lightheadedness, or fainting may occur, especially when you suddenly get up from a lying or sitting position. Getting up slowly may help. If this problem continues or gets worse, check with your doctor.

This medicine can cause changes in heart rhythm, including QT prolongation. It may change the way your heart beats and cause fainting or serious side effects in some patients. Call your doctor right away if you or your child have any symptoms of heart rhythm problems, such as dizziness, feeling faint, or a fast, pounding, or irregular heartbeat.

Paliperidone can temporarily lower the number of white blood cells in your blood, increasing the chance of getting an infection. If you can, avoid people with infections. Check with your doctor right away if you think you are getting an infection or if you get a fever or chills, cough or hoarseness, lower back or side pain, or painful or difficult urination.

This medicine may cause drowsiness, trouble with thinking, or trouble controlling body movements, which may lead to falls, fractures, or other injuries. Do not drive or do anything else that could be dangerous until you know how this medicine affects you.

Check with your doctor before using this medicine with alcohol or other medicines that affect the central nervous system (CNS). The use of alcohol or other medicines that affect the CNS with paliperidone may worsen the side effects of this medicine, including dizziness, poor concentration, drowsiness, unusual dreams, and trouble sleeping. Some examples of medicines that affect the CNS are antihistamines or medicine for allergies or colds, sedatives, tranquilizers, or sleeping medicines, medicine for depression, medicine for anxiety, prescription pain medicine or narcotics, medicine for attention deficit and hyperactivity disorder, medicine for seizures or barbiturates, muscle relaxants, or anesthetics, including some dental anesthetics.

This medicine may make it more difficult for your body to cool itself down. Use care not to become overheated during exercise or hot weather since overheating may result in heat stroke. Also, use extra care not to become too cold while you are using paliperidone. If you become too cold, you may feel drowsy, confused, or clumsy.

This medicine may increase your or your child's weight. Your doctor may need to check your or your child's weight on a regular basis while you are using this medicine.

This medicine may increase prolactin blood levels if used for a long time. Check with your doctor if you have breast swelling or soreness, unusual breast milk production, absent, missed, or irregular menstrual periods, stopping of menstrual bleeding, loss in sexual ability, desire, drive, or performance, decreased interest in sexual intercourse, or an inability to have or keep an erection.

If you plan to have children, talk with your doctor before using this medicine. Some women using this medicine have become infertile (unable to have children).

Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.

Before using paliperidone

In deciding to use a medicine, the risks of taking the medicine must be weighed against the benefits it will provide. This is a decision you and your doctor will make together. For this medicine, consider the following:

Allergies

Tell your doctor if you have ever had any unusual or allergic reactions to this medicine or any other medicines. Also inform your healthcare professional if you have any other allergies, such as to foods, dyes, preservatives, or animals. For over-the-counter products, read the label or package ingredients carefully.

Pediatric

There have not been appropriate studies on how paliperidone affects children with schizophrenia younger than 12 years old and children with schizoaffective disorder. Safety and effectiveness in these age groups have not been established.

Geriatric

Studies so far have not shown any specific problems in older adults that would limit the usefulness of paliperidone. However, older patients are more likely to have kidney issues related to aging, which may require caution and a dose adjustment for those taking paliperidone.

Breast Feeding

There are no adequate studies in women to determine the risk to infants when using this medication while breastfeeding. Weigh the potential benefits against the potential risks before using this medication while breastfeeding.
