Invega is given as an intramuscular injection.
Invega (paliperidone palmitate) is administered via a single intramuscular injection, typically in the deltoid or gluteal muscle. Injection frequency varies - monthly, three-monthly, or six-monthly - depending on the dosage and individual patient needs. A healthcare professional must administer this medication.
Preparing for the Injection
- Confirm Dosage: Verify the prescribed dosage with the patient's medical records.
- Inspect Medication: Check the Invega suspension for particulate matter or discoloration.
- Gather Supplies: Needle, syringe, alcohol swabs, and bandage.
- Patient Positioning: Ensure the patient is comfortably positioned for easy access to the injection site.
Injection Procedure
- Cleanse Site: Thoroughly clean the injection site with an alcohol swab.
- Administer Injection: Inject the entire contents of the syringe slowly and deeply into the muscle.
- Remove Needle: Withdraw the needle at a 90-degree angle.
- Apply Pressure: Apply gentle pressure to the injection site with a sterile bandage.
Injection Site Rotation
Rotating injection sites is important to prevent tissue damage. Recommended sites include:
- Left Deltoid
- Right Deltoid
- Left Gluteus Maximus
- Right Gluteus Maximus
