TREVICTA – Paliperidone uses, dose and side effects


175 mg, 263 mg, 350 mg, 525 mg solution for injection, depot suspension

What TREVICTA is and what it is used for

TREVICTA contains the active substance paliperidone, which is an antipsychotic drug and is used as a maintenance treatment for the symptoms of schizophrenia in adult patients.

If you have responded well to treatment with paliperidone palmitate for injection given once a month, your doctor may start treatment with TREVICTA.

Schizophrenia is a disease with “positive” and “negative” symptoms. Positive symptoms mean the presence of symptoms that normally do not occur. For example, a person with schizophrenia may hear voices or see things that are not there (called hallucinations), believe things that are not true (called delusions), or feel unusually suspicious of others. Negative symptoms mean a lack of behaviors or feelings that normally occur. For example, a person with schizophrenia may appear withdrawn, emotionally depleted, and may have difficulty speaking clearly and logically. People with this disorder may also feel depressed, anxious, burdened with guilt, or tense.

TREVICTA can help relieve the symptoms of your disease and prevent your symptoms from coming back.

What you need to know before you use TREVICTA

Do not use TREVICTA

  • if you are allergic to paliperidone or any of the other ingredients of this medicine (listed in section 6).
  • if you are allergic to any other antipsychotic drug, including the substance risperidone.

Warnings and precautions

Talk to your doctor, pharmacist, or nurse before using TREVICTA.

This medicine has not been studied in elderly patients with dementia. However, elderly patients with dementia who are treated with other similar types of medicine may have an increased risk of having a stroke or dying (see section 4).

All medicines can cause side effects and some of the side effects caused by this medicine can worsen the symptoms of other medical conditions. It is therefore important that you consult your doctor about any of the following conditions that could worsen during treatment with this medicine:

  • if you have Parkinson’s disease
  • if you have ever been diagnosed with the neuroleptic malignant syndrome, a condition where symptoms include fever and muscle stiffness
  • if you have ever had involuntary jerking movements of the face, tongue, or other parts of the body ( tardive dyskinesia )
  • if you know that you have had low levels of white blood cells in the past (this may or may not have been caused by other medicines)
  • if you are diabetic or have a predisposition to diabetes
  • if you have had breast cancer or a tumor in the pituitary gland of the brain
  • if you have heart disease or are being treated for a heart disease that can cause your blood pressure to become low
  • if you have low blood pressure when you stand up or sit up quickly
  • if you have previously had seizures
  • if you have kidney problems
  • if you have liver problems
  • if you have prolonged and/or painful erections
  • if you have disturbances in the regulation of body temperature or have an elevated body temperature
  • if you have an abnormally high level of the hormone et prolactin in your blood or if you have a tumor that may be prolactin dependent
  • if you or someone in your family has had blood clots, antipsychotic medicines have been associated with the formation of blood clots

If you have any of these conditions, talk to your doctor as he/she may want to adjust your dose or monitor you for some time.

In very rare cases, a dangerously low level of a certain type of white blood cell needed to fight infection in the blood has been seen in patients taking this medicine. Your doctor may check your levels of white blood cells.

Even if you have previously tolerated oral paliperidone or risperidone, allergic reactions may rarely occur after you receive an injection of TREVICTA. Seek immediate medical attention if you develop a rash, swelling of the throat, itching, or breathing problems as these may be signs of a serious allergic reaction.

This medicine may cause weight gain. Significant weight gain can hurt your health. Your doctor should check your body weight regularly.

Your doctor should watch for signs of high blood sugar because diabetes mellitus or worsening of existing diabetes has been seen in patients using this medicine. In patients with existing diabetes, blood sugar should be checked regularly.

Because this medicine can reduce the urge to vomit, there is a risk that it may mask the body’s normal response to toxic substances or other medical conditions.

During cataract surgery, it may happen that pupil one (the black circle in the center of the eye) does not increase in size as much as needed. In addition, you can get reduced muscle tension in the iris (the colored part of the eye) during the operation and this can lead to eye damage. If you have eye surgery planned, you must inform your eye doctor that you are using this medicine.

Children and young people

Do not use this medicine in children and adolescents under 18 years of age. It is not known whether it is safe and effective in these patients.

Other medicines and TREVICTA

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

Taking this medicine with carbamazepine (used for epilepsy and as a mood stabilizer) may require a change in your dose of this medicine.

As this medicine primarily has an effect on the brain, the use of other medicines that also work in the brain may cause a worsening of side effects such as drowsiness or other effects on the brain, e.g. other medicines to treat mental conditions, opioids, antihistamines, and sleeping pills.

As this medicine can lower blood pressure et, caution should be taken when the medicine is used together with other medicines that lower blood pressure et.

This medicine can reduce the effect of medicines for Parkinson’s disease and leg cramps (eg levodopa ).

This medicine can cause abnormal ECGs in that it takes longer than usual for an electrical impulse to travel to a certain part of the heart (the condition is called ‘QT prolongation). Other drugs that cause such an effect include certain drugs used to treat heart arrhythmias or to treat infections, as well as other antipsychotic drugs.

If you have had seizures in the past, this medicine may increase your risk of having them. Other drugs that cause such an effect include certain drugs used to treat depression or to treat infection, as well as other antipsychotic drugs.

TREVICTA should be used with caution with drugs that increase activity in the central nervous system (psychostimulants, eg methylphenidate).

TREVICTA with alcohol

Alcohol should be avoided.

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, think you may be pregnant, or are planning to have a baby, ask your doctor or pharmacist for advice before using this medicine. You should not use this medicine during pregnancy unless you have discussed this with your doctor. In newborn babies whose mothers have taken paliperidone during the last trimester (the last three months of pregnancy), the following symptoms may occur: tremors, stiff and weak muscles, sleepiness, agitation, breathing problems, and difficulty eating. If your child develops any of these symptoms, you should contact your doctor.

This medicine can be passed from mother to baby through breast milk, which may be harmful to the baby. You should therefore not breastfeed while using this medicine.

Driving ability and use of machinery

Dizziness, extreme tiredness, and vision problems may occur during treatment with this medicine (see section 4). This must be taken into account in situations where full vigilance is required, e.g. when driving a car or operating machinery.

TREVICTA contains sodium

This medicine contains less than 1 mmol (23 mg) of sodium per dose, i.e. it is almost “sodium-free”.

How to use TREVICTA

This medicine is given to you by your doctor or other healthcare professional. The doctor will let you know when you need the next injection. You mustn’t miss a scheduled dose. If you cannot come to a scheduled visit with the doctor, you should immediately contact him or her to get a new appointment as soon as possible.

You will receive an injection of TREVICTA in either the upper arm or the buttock once every 3 months.

Depending on your symptoms, the doctor may increase or decrease the amount of medicine you receive when it is time for the next scheduled injection.

Patients with kidney problems

If you have mild kidney problems, your doctor will determine which dose of TREVICTA is appropriate based on the dose of paliperidone palmitate for injection once a month that you have received. If you have moderate or severe kidney problems, this medicine should not be used.


Your doctor will decide your dose of this medicine if you have impaired kidney function.

If you have been given too much TREVICTA

You will be given this medicine by trained healthcare professionals, so it is unlikely that you will be given too much.

Patients who have received too much paliperidone may experience the following symptoms:

drowsiness or sleepiness, fast heartbeat, low blood pressure, abnormal EKG (electrical monitoring of the heart), or slow or abnormal movements of the face, body, arms, or legs.

If you stop using TREVICTA

If you stop taking your injections, your symptoms of schizophrenia may get worse. You should not stop using this medicine unless your doctor tells you to.
