Precautions while using paliperidone

It is very important for your doctor to check your progress at regular visits to make sure this medicine is working properly. Blood tests may be needed to check for any unwanted effects.

This medicine may increase 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 have confusion, difficulty speaking, slow speech, inability to speak or move your arms, legs, or facial muscles, double vision, or headache.

Check with your doctor right away if you have difficulty breathing, a fast heartbeat, a 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 have lip smacking or puckering, puffing of the cheeks, rapid or worm-like movements of the tongue, uncontrolled chewing movements, or uncontrolled movements of your arms and legs.

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 have any symptoms of heart rhythm problems, such as dizziness, feeling faint, or a fast, pounding, or irregular heartbeat.

This medicine may increase the amount of sugar in your blood. Check with your doctor right away if you 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 your urine or blood sugar test results. If you have any questions, check with your doctor.

This medicine may increase the amount of cholesterol and fats in your blood. If this happens, your doctor may prescribe medicines to lower the cholesterol and fats in your blood.

This medicine may raise 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 difficulty having or keeping an erection.

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 worsens, check with your doctor.

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

This medicine may cause drowsiness, trouble 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.

This medicine may cause difficulty swallowing, which can lead to food or liquid getting into your lungs, and a prolonged or painful erection that lasts more than 4 hours. Talk to your doctor if you have any concerns about this.

This medicine may make it harder for your body to cool itself down. Be careful not to overheat during exercise or hot weather, as overheating can lead to heat stroke. Also, take extra care not to get too cold while receiving paliperidone injection. If you get too cold, you may feel drowsy, confused, or clumsy.

This medicine may cause weight gain. Your doctor may need to check your weight regularly while you are receiving this medicine. Talk to your doctor about ways to prevent weight gain.

Check with your doctor before using this medicine with alcohol or other medications that affect the central nervous system (CNS). Using alcohol or other medications 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 medications that affect the CNS are antihistamines or medications for allergies or colds, sedatives, tranquilizers, sleeping medications, medications for depression, medications for anxiety, prescription pain medications or narcotics, medications for attention deficit and hyperactivity disorder, medications for seizures or barbiturates, muscle relaxants, or anesthetics, including some dental anesthetics.

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 you have discussed them 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, you and your doctor need to consider the risks of the medicine compared to its benefits. Here are some important points to think about:

Allergies

Let your doctor know if you have ever had any unusual or allergic reaction to this medicine or any other medicines. Also, inform your healthcare professional about any other allergies you may have, 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 age affects the use of paliperidone injection in children. It is not recommended to use Invega Trinza® or Invega Hafyera™ in this group. Safety and effectiveness have not been established.

Geriatric

Studies have not shown any specific problems in older adults that would limit the use of paliperidone injection. However, older patients are more likely to have age-related kidney issues, which may require caution and a dose adjustment for those receiving paliperidone injection.

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