Why do I need this medicine?

Paliperidone is used to treat schizophrenia (an illness that causes changes in perception, thoughts and behaviour).

This medicine may also be used on its own or together with other medicines to treat schizoaffective disorder (a mental illness that can be experienced in addition to the symptoms of schizophrenia).

Paliperidone helps relieve symptoms common in schizophrenia and schizoaffective disorder, such as agitation, distress, distorted thinking and emotional instability.

How do I use this medicine?

Paliperidone is to be given by deep intramuscular (into the muscle) injection. Your doctor or nurse will administer the injection for you.

The dose of Paliperidone will be decided by your doctor. Your doctor will advise you on the treatment regimen depending on your condition, response and tolerability to this medicine.

What should I do if I have forgotten to use this medicine?

Ensure that you keep all appointments with your doctor so that you do not miss any doses. Your doctor also needs to regularly monitor your response to Paliperidone.

If you miss an appointment or miss an injection, alert your doctor or nurse. A replacement appointment or injection should be given as soon as possible.

When should I not use this medicine?

Alert your doctor immediately if you are allergic (rashes, breathlessness, swollen eyes) to Paliperidone or similar medicine such as risperidone.

What should I take note of while using this medicine?

Inform your doctor if you have the following conditions:
  • neuroleptic malignant syndrome (a neurological disorder characterised by muscle rigidity, fever and blood pressure changes)
  • heart or blood vessel disease e.g. heart rhythm disorder, heart failure, heart attack, stroke
  • tardive dyskinesia (a condition which causes uncontrollable twitching movements of the mouth, tongue and limbs)
  • kidney disease
  • liver disease
  • diabetes or at risk for diabetes e.g. obesity, family history
  • history of blood clot disorder
  • epilepsy (fits or seizures), including those with history of seizures, head trauma, brain damage, alcoholism
  • hyperprolactinaemia (high levels of the hormone prolactin in your blood)
  • dementia (group of symptoms affecting thinking and social abilities)
  • Parkinson’s disease (a brain disease that affects movement)
If you are going for an operation such as an eye surgery, inform your doctor that you are using Paliperidone.

Paliperidone may cause your white blood cell count to drop drastically. This may put you at higher risk for infections. For as long as you are being treated with Paliperidone, you will need to have regular blood tests done. These blood tests are very important for you. These tests help your doctor to check that your white blood cell counts are within the normal range. Your doctor will advise you about how often you need to have these blood tests.

Paliperidone may also cause your blood sugar levels to rise. Monitor your blood sugar levels more regularly if you have diabetes or a family history of diabetes. Ask your doctor how often you need to have your blood sugar levels monitored.

Paliperidone may affect the ability of your body to adjust to temperature changes in the environment. Avoid exposure to very cold or very hot environments. Avoid strenuous exercise and activities like going to the sauna. Drink more water to prevent dehydration.

Keep your appointments with your doctor. Your doctor needs to monitor your condition and check your response to the medication regularly.
  • Your doctor may need to do certain tests to make sure that your heart, lungs, liver, and kidney function is normal before your treatment initiation and thereafter depending on your doctor’s advice.
  • Routine tests (e.g. complete blood count, electrolyte, blood cholesterol/lipid, glucose test, and eye examination) may be done while you are being treated with this medicine. Your doctor will advise you about how often you will need to have these tests.
For as long as you are using this medicine, you may need to regularly monitor your blood pressure and weight.
