This medicine contains paliperidone as active ingredient. It is an antipsychotic drug, belonging to the class of psychoactive medicines, that has a specific effect on certain neurotransmitters (dopamine en serotonin), the chemical messengers in the brain. Because antipsychotic drugs depress the action of dopamine and serotonin, they can disturb its balance with another chemical in the brain, acetylcholine. If that occurs, symptoms like those of parkinsonism can appear.

Warnings and Cautions

•    The medicine has been associated with increased mortality in seniors with dementia or Alzheimer’s disease. The specific causes of death related to atypical psychotic drugs were either due to a heart-related event or infection, mostly pneumonia.

•    A series set of side effects known as neuroleptic malignant syndrome has been associated with some antipsychotic drugs. The symptoms that constitute neuroleptic malignant syndrome include:

•   High fever

•   Muscle rigidity

•   Mental changes

•   Irregular pulse

•   Irregular blood pressure

•   Sweating

•   Abnormal heart rhythm.

Neuroleptic malignant syndrome is potentially fatal and requires immediate medical attention.

•   The medicine can produce uncontrolled movements including:

•   Tremor

•   Spasm of neck muscles

•   Rolling back of the eyes

•   Convulsions

•   Difficulty swallowing

•   Symptoms associated with Parkinson’s disease

These effects usually disappear after the drug has been discontinued.  Face, tongue, and jaw symptoms may persist, especially in older  women. Contact your doctor immediately if you experience any of these symptoms.

•   This medication should not be given to people with:

•   Severe narrowing of the gastrointestinal tract

•   Small bowel inflammation

•   Narrowing of the bowels

•   Slowed gastrointestinal motility

•   Past history of peritonitis

•   Cystic fibrosis

•    Because these drugs can have permanent as well as temporary side effects, the minimum necessary dosage is used. This is found by starting with a low dose and increasing it until symptoms are controlled. Sudden withdrawal of antipsychotics after more than a few weeks can cause nausea, vomiting, sweating, headache and restlessness. For this reason the dose is reduced gradually when the drug treatment needs to be stopped.
