Consumer Medicine Information
What is in this leaflet
This leaflet answers some of the common questions about Invega Trinza. It does not contain all of the available information. It does not take the place of talking to your doctor or pharmacist.
If you have any concerns about using Invega Trinza, ask your doctor or pharmacist. Your doctor and pharmacist have more information.
Keep this information handy. You can refer to it later if you have any questions.
What Invega Trinza is used for
Invega Trinza belongs to a group of medicines called antipsychotic agents which improve the symptoms of certain type of mental illness.
It is used to treat symptoms of schizophrenia, a mental illness with disturbances in thinking, feelings and behaviour. Invega Trinza helps to correct a chemical imbalance in the brain associated with this condition. It can also be used to lessen the chance of your schizophrenia symptoms from coming back.
Some of the most common symptoms of schizophrenia may include:
- Seeing, hearing, or sensing things that are not there (hallucinations)
- a false belief or wrong judgment, sometimes associated with hallucinations, held with conviction despite evidence to the contrary (delusions)
- Not trusting others and feeling very suspicious (paranoia)
- Avoiding family and friends and wanting to be alone
It may take some time before your symptoms of schizophrenia start to improve. Remember that Invega Trinza is one part of your overall treatment plan. It is important to keep all your appointments so you can get your treatments on time and your doctor can check your progress.
Your doctor, however, may prescribe this medicine for another use.
Ask your doctor if you have any questions about why it has been prescribed to you.

Do not use it after the expiry date printed on the pack. If you use it after the expiry date has passed, it may not work as well.

How is it given
Using it for the first time
Treatment with Invega Trinza will not be started by your doctor until they know you have tolerated Invega Sustenna for at least 4 months.
At the start of treatment you may have a fall in blood pressure making you feel dizzy on standing up, or your heart may beat faster. These should go away after a few days.
Tell your doctor if these symptoms continue or worry you.
How much of it will be given
Your doctor will decide the strength of Invega Trinza suitable for you.
How is it given
Invega Trinza will be given to you by injection by a healthcare professional. It is a medicine designed to gradually release the active ingredient into your body so that you do not have to take this medicine every day.
Invega Trinza is a longer acting product where you will get a dose only once every 3 months.
Your doctor or healthcare provider will give you the injection into the upper arm or buttocks. You may feel some pain or discomfort, but this may become less over time.
How often it is given
After you have been given the first dose, it is recommended that Invega Trinza is given once every 3 months. However, your doctor may change the dose depending on how your body respond to the medicine.
How many injections you will need
Invega Trinza helps control your condition, but will not cure it. Therefore, you will need regular injections. Do not miss any injections, even if you feel better.
What if you miss a dose
It is very important to keep all your appointments and get your medicine on time.
Contact your doctor as soon as you can if you think you are going to miss or have missed your appointment. Your doctor will decide what you should do next.
For patients with kidney problems
Invega Trinza has not been studied in patients whose kidney is not functioning properly. Your doctor will decide the dose suitable for you.
For patients with mild kidney problems, the maximum recommended dose is 350 mg.
Use of Invega Trinza is not recommended in patients with moderate or severe kidney problems.
Invega Trinza is not recommended for children under 18 years.
As Invega Trinza is given to you under the supervision of your doctor, it is very unlikely that you will receive too much.
However, if you experience any side effects after receiving Invega Trinza, tell your doctor immediately or go to Accident and Emergency at your nearest hospital. You may need urgent medical attention.
While you are using it
Things you must do
Follow your doctor’s instructions carefully. Do not miss an injection or stop the treatment without consulting your doctor first. Your doctor will be happy to discuss any questions you may have with your treatment.
Tell your doctor if you are pregnant or planning to become pregnant.
Tell your doctor immediately 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 Trinza. 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.
If you are planning to have operation on your eye, make sure you tell your eye doctor that you are taking this medicine.
Tell any other doctors, dentists, and pharmacists who want to start you on any new medicines listed under ‘Taking other medicines’ (above) that you are taking Invega Trinza. Your doctor, dentist or pharmacist will need to consider whether any new medicines will affect your Invega Trinza.
Things you must not do
Do not miss any injections or any appointments with the doctor.
Do not drink alcohol. Invega Trinza can increase the effects of alcohol.
Things to be careful of
Ask your doctor or pharmacist before taking any other medicines.
Invega Trinza can increase the effects of medicines which you’re your reactions. Always ask your doctor or pharmacist before taking other medicines including herbal treatments and medicines that can be bought in a pharmacy or supermarket.
Avoid driving or operating machinery until you are sure that Invega Trinza does not affect your alertness. Invega Trinza may cause dizziness, drowsiness or light-headedness in some people. Make sure you know how you react to Invega Trinza before you drive a car, operate machinery, or do anything else that could be dangerous if you are dizzy.
If the medicine makes you feel light-headed, dizzy or faint, be careful when getting up from a sitting or lying position. Getting up slowly may help.
Avoid excessive eating. There is a possibility of weight gain when taking Invega. Your doctor may monitor your body weight or recommend strategies to assist with weight management.
All medicines may have some unwanted side effects. Sometimes they are serious, but most of the time they are not. Your doctor has weighed the risks of using this medicine against the benefits they expect it will have for you.
All medicines can have side effects. You may need medical treatment if you get some of the side effects.
