WARNING

Invega Trinza is a long-acting injectable medication used to treat schizophrenia in adults. While it can be effective in managing symptoms, it also carries certain risks and potential side effects. Here are some important considerations:

• Extrapyramidal Symptoms (EPS): Invega Trinza may cause movement disorders such as tremors, muscle stiffness, and involuntary muscle movements. These symptoms are known as EPS and can be distressing. Your healthcare provider may prescribe additional medications to manage these side effects if they occur.
• Metabolic Effects: Like many antipsychotic medications, Invega Trinza can lead to metabolic changes, including weight gain, increased blood sugar levels, and elevated cholesterol and triglyceride levels. Regular monitoring of weight, blood glucose, and lipid levels is necessary to address these potential effects.
• Neuroleptic Malignant Syndrome (NMS): NMS is a rare but potentially life-threatening condition that can occur with the use of antipsychotic medications. It is characterized by high fever, muscle stiffness, confusion, and irregular heartbeat. If any of these symptoms occur, immediate medical attention is necessary.
• Hyperprolactinemia: Invega Trinza may cause an increase in the hormone prolactin, which can lead to symptoms like breast enlargement, milk production, and irregular menstrual periods. In some cases, it can affect sexual function. Monitoring prolactin levels and discussing any related symptoms with your doctor is important.
• Cardiovascular Effects: Antipsychotic medications, including Invega Trinza, may increase the risk of heart-related complications such as irregular heart rhythms and changes in blood pressure. Regular monitoring of cardiovascular health is essential, especially for individuals with existing heart conditions.
• Allergic Reactions: Although rare, some individuals may experience allergic reactions to Invega Trinza. Symptoms may include rash, itching, swelling, severe dizziness, or difficulty breathing. Seek immediate medical attention if you develop any signs of an allergic reaction.

It’s important to note that this is not an exhaustive list of risks and side effects associated with Invega Trinza. Always consult your healthcare provider for personalized information and to discuss the potential benefits and risks of this medication in your specific situation.

Why is this medication prescribed?

Invega Trinza is prescribed for the treatment of schizophrenia in adults. Schizophrenia is a chronic mental disorder that affects a person’s thinking, emotions, and behavior. It is characterized by symptoms such as hallucinations (seeing or hearing things that are not there), delusions (false beliefs), disorganized thinking, and a lack of motivation.

Invega Trinza belongs to a class of medications called antipsychotics, and its active ingredient is paliperidone palmitate. It is an extended-release formulation that is administered as a long-acting injection once every three months. This allows for continuous and sustained delivery of the medication in the body.

The primary goal of prescribing Invega Trinza is to reduce or alleviate the symptoms of schizophrenia, including hallucinations, delusions, and disorganized thinking. By controlling these symptoms, the medication aims to improve a person’s overall functioning, quality of life, and ability to engage in daily activities.

• Dose Adjustment: The dosage of Invega Trinza may need to be adjusted based on the individual’s response and tolerability. It is important to follow the guidance of the prescribing healthcare professional regarding dosage changes.
