Question 3

How does Invega work?

Accepted Answer

Mechanism of Action

Invega, which contains the active ingredient paliperidone, works by altering the activity of certain natural substances in the brain called neurotransmitters. These chemicals are responsible for sending signals between nerve cells and play a significant role in mood, behavior, and thought processes.

The medication primarily targets two specific neurotransmitters:

Dopamine: It helps regulate the overactivity of dopamine, which is often linked to symptoms like hallucinations and delusions.

Serotonin: It also affects serotonin levels, which can help improve mood, cognitive function, and social interaction.

While the exact way Invega works is not fully understood, researchers believe it functions by blocking specific receptors for these chemicals on the surface of brain cells. By modulating these pathways, the medication helps to decrease abnormal excitement in the brain and restore a more stable chemical balance.

Question 7

What is the dosage of Invega and how do I take it?

Accepted Answer

Oral Administration

The oral tablet is typically taken once daily, usually in the morning. It may be taken with or without food, but it should be taken the same way each time to ensure consistent absorption.

The tablet must be swallowed whole with water or other liquids. Do not crush, chew, or break the tablet, as this can interfere with the extended-release mechanism and release the medication too quickly.

Injectable Administration

Invega is also available in long-acting injectable forms administered by a healthcare professional into the muscle of the upper arm or buttocks. Depending on the specific formulation prescribed, these injections are given at different intervals:

Once every month

Once every three months

Once every six months

Missed Doses

If you miss a dose of the oral tablet, take it as soon as you remember. However, if it is almost time for your next scheduled dose, skip the missed dose and resume your regular schedule. Do not take extra medicine to make up for a missed dose.

If you miss an appointment for a scheduled injection, contact your healthcare provider immediately to reschedule. It is important to receive these injections on time to maintain the effectiveness of the treatment.

Question 8

Is Invega safe during pregnancy and breastfeeding?

Accepted Answer

Pregnancy

The safety of using Invega during pregnancy has not been fully established. Research indicates that newborns exposed to antipsychotic medications like Invega during the third trimester may experience symptoms after birth, including:

Muscle stiffness or weakness

Tremors

Sleepiness

Breathing problems

Difficulty feeding

If you become pregnant while taking Invega, do not stop the medication without consulting your doctor. Stopping treatment abruptly can cause a relapse of symptoms. There is a pregnancy registry available to monitor the health of individuals and their babies who are exposed to antipsychotics during pregnancy.

Breastfeeding

Invega can pass into breast milk and may be absorbed by a nursing infant. Because the effects on the baby are not fully understood, it is important to talk with a healthcare professional about the risks and benefits of breastfeeding while using this medication. They can help determine the safest course of action for both the parent and the child.

Question 9

Available Forms

Invega is provided in two primary forms: oral tablets and long-acting injections.

Extended-Release Tablets

The oral form of this medication is an extended-release tablet. It is designed to be taken once daily. These tablets use a special delivery system that releases the medicine at a controlled rate throughout the day. It is important to swallow the tablet whole with liquid and not to crush, chew, or divide it.

Injectable Suspensions

Paliperidone is also available as an extended-release injectable suspension. These injections are administered by a healthcare provider into the muscle of the arm or buttocks. There are several versions of the injection that differ by how often they are administered:

Once-monthly injections

Injections administered every three months

Injections administered every six months

A healthcare provider determines the appropriate form and schedule based on the patient's treatment needs and how they have responded to previous doses of the medication.

Question 10

What is the FDA approval status of Invega?

Accepted Answer

FDA Approval and Indications

Invega (paliperidone) is approved by the U.S. Food and Drug Administration (FDA) for the treatment of schizophrenia in adults and adolescents aged 12 to 17 years. It is also approved for the treatment of schizoaffective disorder in adults, where it may be used alone or in combination with mood stabilizers or antidepressants.

Boxed Warning

The FDA has issued a boxed warning for Invega because elderly patients with dementia-related psychosis who are treated with antipsychotic medications are at an increased risk of death. Invega is not FDA-approved for the treatment of patients with dementia-related psychosis.

Regulatory Status and Formulations

Invega is a prescription medication and is available in several FDA-approved formulations designed for different dosing schedules:

Oral Tablets: Extended-release tablets taken once daily.

Intramuscular Injections: Long-acting injectable versions administered by healthcare professionals. These include formulations administered once monthly, every three months, or every six months.

Question 11

What should I know about Invega and withdrawal?

Accepted Answer

Managing Discontinuation

It is important not to stop taking Invega (paliperidone) without first consulting your doctor. Stopping the medication suddenly may cause the symptoms of schizophrenia or schizoaffective disorder to return. Your healthcare provider will typically recommend a gradual reduction in dosage to help prevent a relapse.

Long-Acting Injectables

Invega is available in several long-acting injectable forms, such as Invega Sustenna, Invega Trinza, and Invega Hafyera. Because these medications are designed to release slowly over weeks or months, the drug remains in your system for a significant amount of time after the last injection. If you stop treatment, any withdrawal effects or the return of original symptoms may not appear immediately.

Withdrawal in Newborns

If Invega is taken during the last three months of pregnancy, the baby may experience withdrawal symptoms after birth. These symptoms can include:

Agitation or irritability

Feeding problems

Muscle stiffness or limpness

Sleepiness

Breathing difficulties

Tremors

If you are pregnant or planning to become pregnant, discuss the risks and benefits of continuing Invega with your doctor to manage potential risks to the newborn.
