1. Why am I using INVEGA HAFYERA?

INVEGA HAFYERA contains the active ingredient paliperidone palmitate. INVEGA HAFYERA belongs to the class of antipsychotic medicines and is used to treat schizophrenia in adults (18 years of age and older).

INVEGA HAFYERA is used after you have been treated with the 1-month injection for at least 4 months or the 3-month injection for at least one injection cycle. After your symptoms have been adequately treated with the 1-month or 3-month injection, INVEGA HAFYERA is used to keep the symptoms under control, i.e., to prevent its recurrence.

INVEGA HAFYERA injections are given once every 6 months.

Schizophrenia is a mental illness with symptoms such as hearing things, seeing or sensing things that are not there, mistaken beliefs, unusual suspiciousness, becoming withdrawn, incoherent speech, and reduced behavioral/emotional responses. People living with schizophrenia may also feel depressed, anxious, guilty, or tense.

2. What should I know before I use INVEGA HAFYERA?


Do not use INVEGA HAFYERA if:

  1. you are allergic to paliperidone, or to risperidone which is another antipsychotic medicine similar to paliperidone, or any of the ingredients listed at the end of this leaflet.
  2. Always check the ingredients to make sure you can use this medicine.

Allergic reaction can be recognised for instance by skin rash, itching, shortness of breath or swollen face. If any of these occur, contact your doctor right away.

Check with your doctor if you:

  • have any other medical conditions:
    – Parkinson’s disease or Dementia
    – have ever been diagnosed with a condition whose symptoms include high temperature and muscle stiffness (also known as Neuroleptic Malignant Syndrome)
    – have ever experienced abnormal movements of the tongue or face (Tardive Dyskinesia)
    – are at risk for diabetes or high blood sugar
    – have heart disease or heart disease treatment that makes you prone to low blood pressure, or are prone to drop in blood pressure or feeling dizzy when you stand up from lying or sitting positions
    – have epilepsy
    – have or have had low white blood cell counts in your blood. Let your doctor know right away if you develop a fever or infection while being treated with INVEGA HAFYERA
    – have a loss of kidney function. Your doctor may reduce your dose of INVEGA HAFYERA if your kidney function is reduced
    – have a loss of liver function
    – have prolonged and/or painful erection
    – have had problems with body temperature regulation
    – have a history of blood clots (or someone else in your family has a history of blood clots). Blood clots in the lungs and legs have been seen in patients taking medicines that are similar to INVEGA HAFYERA. Blood clots in the lungs can be fatal.
  • Even for patients who have previously tolerated oral paliperidone or risperidone, allergic reactions have been reported very rarely after receiving the 1-month paliperidone palmitate injection product and it is possible that allergic reactions could occur with INVEGA HAFYERA.
  • Body weight changes have been seen in patients receiving antipsychotic medicines. Your doctor may monitor your body weight while you are being treated with INVEGA HAFYERA.
  • During an operation on the eye for cloudiness of the lens (cataract), the pupil (the black circle in the middle of your eye) may not increase in size as needed. Also, the iris (the coloured part of the eye) may become floppy during surgery and that may lead to eye damage. If you are planning to have an operation on your eye, make sure you tell your eye doctor that you are taking this medicine.
  • take any medicines for any other condition

During treatment, you may be at risk of developing certain side effects. It is important you understand these risks and how to monitor for them. See additional information under Section 6. Are there any side effects?

Pregnancy and breastfeeding

  • Check with your doctor if you are pregnant or intend to become pregnant.
    You should not take INVEGA HAFYERA during pregnancy unless this has been discussed with your doctor. Shaking, muscle stiffness and/or weakness, sleepiness, agitation, breathing problems, or difficulty in feeding may occur in your newborn baby if you use INVEGA HAFYERA at any time during your pregnancy, and even if you used INVEGA HAFYERA before becoming pregnant.
  • Do not breastfeed while you are being treated with INVEGA HAFYERA. Consult your doctor in that case.

Patients with kidney or liver impairment

  • Your doctor may adjust your dose of INVEGA HAFYERA based upon your kidney function. INVEGA HAFYERA has not been studied in patients with liver impairment, but based on experience with orally-administered paliperidone, adjustment in dose is typically not necessary in patients with mild to moderate liver impairment. The doctor will use his/her best judgement if INVEGA HAFYERA is being considered for use in a patient with severe liver impairment.

Elderly Patients

INVEGA HAFYERA 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 stroke or death.

Children and Adolescents

  • INVEGA HAFYERA is not for treating people with schizophrenia who are younger than 18 years old.

3. What if I am taking other medicines?

Some medicines may interfere with INVEGA HAFYERA and affect how it works.

Tell your doctor or pharmacist if you are taking any other medicines, including any medicines, vitamins or supplements that you buy without a prescription from your pharmacy, supermarket or health food shop.

  • some medicines may increase the levels of paliperidone in your blood, which may produce an increase in side effects resembling overdose of INVEGA HAFYERA
  • Since INVEGA HAFYERA can make you sleepy or drowsy, care should be taken when INVEGA HAFYERA is taken with other medicines that can also cause sleepiness or drowsiness.
  • Since INVEGA HAFYERA can lower blood pressure, care should be taken when INVEGA HAFYERA is taken with other medicines that lower blood pressure.
  • INVEGA HAFYERA can reduce the effect of medicines against Parkinson’s disease and restless legs syndrome (e.g., levodopa).
  • INVEGA HAFYERA should be used with caution with medicines that increase the activity of the central nervous system (psychostimulants such as methylphenidate).

Check with your doctor or pharmacist if you are not sure about what medicines, vitamins or supplements you are taking and if these affect INVEGA HAFYERA.

4. How do I use INVEGA HAFYERA?

How much to use

  • The first dose of INVEGA HAFYERA is determined by your doctor or healthcare professional based on your existing dose for 1-month injection product (INVEGA SUSTENNA) or 3-month injection product (INVEGA TRINZA)
  • INVEGA HAFYERA is given by injection into the muscle of your buttock once every 6 months. Depending on your symptoms, your doctor may increase or decrease the dose of medicine you receive at the time of your scheduled injection.


  • INVEGA HAFYERA is only used after you have been treated with the 1-month injection product (INVEGA SUSTENNA) for at least 4 months or the 3-month injection (INVEGA TRINZA) for at least one injection cycle.
  • Like the 1-month and the 3-month injection, INVEGA HAFYERA is administered by your doctor or other healthcare professional in a doctor’s office or clinic. Your doctor will tell you when to come into the doctor’s office or clinic for the injection. It is important not to miss your scheduled dose.

If you forget to use INVEGA HAFYERA

  • If you cannot keep your appointment with the doctor, make sure you call your doctor right away so another appointment can be made as soon as possible. Your doctor may also want to see you even if you are not scheduled for an injection of INVEGA HAFYERA.

If you use too much INVEGA HAFYERA

This medicine will be given to you under medical supervision; it is, therefore, unlikely that you will be given too much.

Patients who have been given too much paliperidone may experience the following symptoms: drowsiness or sleepiness, fast heart rate, low blood pressure, an abnormal electrocardiogram (electrical tracing of the heart), or slow or abnormal movements of the face, body, arms, or legs.

Because INVEGA HAFYERA is stored and administered by healthcare professionals, the potential for overdosage by patients is low.

In overdose, one or more of the following signs may occur: reduced consciousness, drowsiness, sleepiness, excessive trembling, excessive muscle stiffness, fast beating heart, and low blood pressure. Cases of abnormal electrical conduction in the heart (QT prolongation) and convulsion have been reported.

Overdose can happen if you are taking other medications together with INVEGA HAFYERA.

If you experience the above symptoms, you should immediately contact your doctor.

5. What should I know while using INVEGA HAFYERA?

Things you should do

Follow your doctor’s instructions carefully.

If you are planning to have operation on your eye, make sure you tell your eye doctor that you are taking this medicine.

Tell your doctor if you become pregnant or intend to become pregnant.

Call your doctor straight away if you:

  • notice any involuntary movements of the tongue, mouth, cheeks or jaw which may progress to the arms and legs.
    These may be symptoms of a condition called tardive dyskinesia, which can develop in people taking antipsychotic medicines, including INVEGA HAFYERA. This condition is more likely to occur during longer term treatment and in older women. In very rare cases, these symptoms may be permanent. However, if detected early, these symptoms are usually reversible.

Remind any doctor or dentist you visit that you are using INVEGA HAFYERA.

Things you should not do

  • Do not miss an injection or stop the treatment without consulting your doctor first.

Driving or using machines

Be careful before you drive or use any machines or tools until you know how INVEGA HAFYERA affects you.

INVEGA HAFYERA might affect your alertness and may affect your vision. You are, therefore, advised not to drive or operate machines before you know how sensitive you are to this medicine.

Drinking alcohol

Alcohol should be avoided when taking INVEGA HAFYERA.

Looking after your medicine

  • INVEGA HAFYERA is stored and administered by healthcare professionals so it is unlikely that you will store this medicine at home. If you do,
    – store below 25°C in a horizontal position. See arrows on product carton for proper orientation.
    – store it in a cool dry place away from moisture, heat or sunlight; for example, do not store it in the bathroom or near a sink, or in the car or on window sills.

Do not use this medicine after the expiry date.

Keep it where young children cannot reach it.

Getting rid of any unwanted medicine

Medicines should not be disposed of via wastewater or household waste. Ask your pharmacist how to dispose of medicines no longer required. These measures will help to protect the environment.
