1. What Inpalix is and what it is used for

Paliperidone contains the active substance paliperidona, which belongs to a class of antipsychotic medicines.

Paliperidona is used to treat schizophrenia in adults and adolescents from the age of 15 years.

Schizophrenia is a disorder that causes symptoms such as hearing, seeing, or feeling things that do not exist, having false beliefs, excessive mistrust, social withdrawal, disorganized speech, and blunting of behavior and emotions. People with this disorder may also feel depressed, anxious, guilty, or tense.

Paliperidona is also used to treat schizoaffective disorder in adults.

Schizoaffective disorder is a mental condition in which a person experiences several of the symptoms of schizophrenia (listed in the paragraph above) as well as mood disorder symptoms (feelings of euphoria, sadness, agitation, distractibility, insomnia, pressured speech, loss of interest in daily activities, excessive or insufficient sleep, excessive or reduced food intake, and recurrent thoughts of suicide).

Paliperidona may help relieve the symptoms of your illness and prevent them from returning.

2. What you need to know before taking Inpalix

Do not take paliperidone

• if you are allergic to paliperidone, risperidone, or any of the other components of this medicine (listed in section 6).

Warnings and precautions

Talk to your doctor, pharmacist, or nurse before starting paliperidone.

• Patients with schizoaffective disorder treated with this medicine should be closely monitored for possible shifts from manic to depressive symptoms.
• This medicine has not been studied in elderly patients with dementia. However, elderly patients with dementia who are treated with similar medicines may have an increased risk of stroke or death (see section 4, Possible side effects).
• if you have Parkinson's disease or dementia.
• if you have ever been diagnosed with a condition characterized by high body temperature and muscle rigidity (also known as Neuroleptic Malignant Syndrome).
• if you have ever experienced abnormal movements of the tongue or face (Tardive Dyskinesia).
• You should be aware that these two disorders may be caused by this type of medicine.
• if you have previously had low levels of white blood cells (which may or may not have been caused by other medicines).
• if you have diabetes or are prone to diabetes.
• if you have heart disease or are being treated for heart conditions that may make you more susceptible to low blood pressure.
• if you have epilepsy.
• if you have a swallowing disorder, or stomach or intestinal problems that reduce your ability to swallow food or digest it with normal intestinal movements.
• if you have conditions associated with diarrhea.
• if you have kidney problems.
• if you have liver problems.
• if you experience prolonged and/or painful erection.
• if you have difficulty regulating body temperature or feel overheated.
• if you have abnormally high levels of prolactin hormone in the blood, or if you have a tumor that may be prolactin-dependent.
• if you or someone in your family has a history of blood clots, as antipsychotics have been associated with blood clot formation.

If you have any of these conditions, please consult your doctor, as a dose adjustment or monitoring may be necessary.

Due to the rare occurrence in patients treated with paliperidone of a dangerously low count of a type of white blood cells essential for fighting infections, your doctor may monitor your white blood cell count.

Paliperidone may cause weight gain. Significant weight gain can negatively affect your health. Your doctor will regularly monitor your weight.

Cases of diabetes mellitus or worsening of pre-existing diabetes mellitus have been observed in patients treated with paliperidone. Your doctor should check for signs of increased blood sugar. In patients with pre-existing diabetes mellitus, blood sugar levels should be monitored regularly.

During cataract surgery (clouding of the lens), the pupil (the black circle in the center of the eye) may fail to dilate as needed. Additionally, the iris (the colored part of the eye) may become floppy during surgery, which could lead to eye damage. If you are considering eye surgery, make sure to inform your ophthalmologist that you are taking this medicine.

Children and adolescents

Paliperidone must not be given to children and adolescents under 15 years of age for the treatment of schizophrenia.

Paliperidone must not be given to children and adolescents under 18 years of age for the treatment of schizoaffective disorder.

This is because it is unknown whether paliperidone is safe or effective in this age group.

Other medicines and paliperidone

Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines.

Abnormalities in heart electrical function may occur when this medicine is taken together with other medicines used to control heart rhythm, or other medicines such as antihistamines, antimalarials, or antipsychotics.

Since this medicine acts mainly in the brain, it may interact with other medicines (or alcohol) that also act on the brain, leading to additive effects on brain function.

This medicine may lower blood pressure, so caution is needed if taken together with other medicines that also lower blood pressure.

This medicine may reduce the effectiveness of medicines used for Parkinson's disease and restless legs syndrome (e.g., levodopa).

The effects of this medicine may be altered if taken with medicines that affect intestinal motility (e.g., metoclopramide).

Dose reduction of this medicine should be considered when administered concomitantly with valproate.

The use of oral risperidone together with this medicine is not recommended, as this combination may lead to an increase in adverse effects.

Taking paliperidone with alcohol

You should avoid consuming alcohol during treatment with this medicine.

The following symptoms may occur in newborn babies whose mothers have been treated with paliperidone during the third trimester of pregnancy (last three months): tremors, muscle stiffness and/or weakness, drowsiness, agitation, breathing difficulties, and feeding problems. If your baby develops any of these symptoms, contact your doctor immediately.

You must not breastfeed while taking this medicine.
