What Invega Sustenna is used for
Invega Sustenna belongs to a group of medicines called antipsychotic agents which improve the symptoms of certain types of mental illness.
It is used to treat symptoms of schizophrenia, a mental illness with disturbances in thinking, feelings and behaviour. Invega Sustenna 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)
Believing that what other people say is not true (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 Sustenna 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.

How much of it will be given
Your doctor will decide the strength of Invega Sustenna which is suitable for you.
How is it given
Invega Sustenna will be given to you by injection by a healthcare professional. It is a medicine designed to gradually release into your body so that you do not have to take this medicine every day.

However, your doctor might decide to give you a lower or higher dose in the range of 25 mg to 150 mg based on your condition and kidney function.
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 two doses, it is recommended that Invega Sustenna is given once every month. However, your doctor may change the dose depending on how your body responds to the medicine.
