What is Invega Trinza?

Invega Trinza is an atypical antipsychotic that is given once every 3 months. It is used to treat a mental disorder called schizophrenia.

Invega Trinza contains paliperidone. Another well-known antipsychotic drug called Risperdal (risperidone) is converted into paliperidone once it is in the body. Invega Trinza is an extended-release version of paliperidone that helps to overcome the fluctuations in blood levels of the drug that are seen after it is taken by mouth as an immediate-release formulation such as Risperdal. It also helps to avoid the problem of remembering to take a medication everyday.

It is not fully understood how Invega Trinza works, but it helps to adjust the levels of chemicals in the brain called dopamine and serotonin. These chemicals are called neurotransmitters and it's thought that an imbalance in these chemicals plays a role in schizophrenia.

Invega Trinza was approved by the US Food and Drug Administration (FDA) in 2015.

What is Invega Trinza used for?

Invega Trinza is a prescription medicine given by injection by a healthcare professional and used to treat schizophrenia.

Invega Trinza is used in people who have been treated with Invega Sustenna 1 time a month injections for at least 4 months.

It is not known if Invega Trinza is safe and effective in children under 18 years of age.
