What Is Trinza
InvegaTrinza is a longacting injection of paliperidone palmitate thats designed to stay in your system for three months. Its the onceevery12weeks cousin of the oncemonthly InvegaSustenna you might already know.
Why Choose a 3Month Shot?
For many people, fewer clinic visits mean fewer chances to forget a dose, and it can free up a lot of mental space. The tradeoff? You need to be stable on the monthly formulation firstusually at least four monthsso that the body can adjust before jumping to the threemonth schedule.
Dosage Strengths
Trinza comes in four injectable strengths. Knowing these makes the invega trinza dosage conversation a lot smoother.
| Strength (mg) | Corresponding Dose Name |
|---|---|
| 273 mg | Low dose (1month 78mg 4) |
| 410 mg | Mediumlow dose |
| 546 mg | Medium dose |
| 819 mg | High dose (1month 205mg 4) |
These numbers come straight from the , so you can trust theyre spoton.
Choosing the Right Strength
Most clinicians start with the dose that matches the total amount you were getting from the monthly shot. For example, if you were on 156mg per month of Sustenna (the usual starting dose), multiplying by four gives you roughly 624mg. In practice, youd round to the nearest available strength546mg or 819mgbased on how youve been tolerating the medication.
Standard Schedule
The classic invega trinza dosing chart follows a strict 12week interval. Below is a quick visual you can bookmark or print.
| Injection # | Date | Next Dose Window |
|---|---|---|
| 1 | Day0 (initial) | Day8414days |
| 2 | Day84 | Day16814days |
| 3 | Day168 | Day25214days |
The invega trinza dosing window is generousabout two weeks before or after the exact 12week markso theres a little wiggle room if life gets busy.
Can It Be Every 10 Weeks?
Technically the label says every 12 weeks, but some clinicians may adjust the interval to 10 weeks for specific reasons. That shift is not standard, so youd need a clear conversation with your prescriber before anything changes.
Dose Conversion
Switching from InvegaSustenna to Trinza can feel like swapping a regular coffee for a tripleshot espressobig change, same core ingredient. Heres the stepbystep invega trinza dose conversion guide.
Step 1: Calculate Your Monthly Total
Take the last three months of your Sustenna dose and add them up. Example: 156mg each month3=468mg.
Step 2: Multiply by Four
Because Trinza lasts four times as long, multiply that total by four. 468mg4=1,872mg.
Step 3: Match to Available Strengths
Divide the result by the number of injections youll receive over the same period (usually 1). Then round to the nearest strength from the table above. In our example, youd likely land on the 819mg dose with a planned taper if needed.
One patient I chatted with (lets call her Maya) shared how she felt a bit nervous about the math. Her psychiatrist walked her through the conversion on a whiteboard, and she left feeling reassured because every number had a purpose. Realworld stories like Mayas make the process feel less like a spreadsheet and more like a collaborative plan.
Missed Dose
Life throws curveballstravel, illness, or simply forgetting. If you miss your Trinza appointment, dont panic. Heres what to do.
Within the Dosing Window?
If youre still inside the invega trinza dosing window (up to 14days early or late), you can get the injection right away and then continue with the original schedule.
Outside the Window?
When youre beyond that twoweek buffer, your doctor may advise a resetyoud get the missed dose as soon as possible, then start a fresh 12week cycle. Its essential to contact your healthcare team quickly so they can guide you on any needed blood level checks.

Injection Technique
Getting an injection every three months sounds easy, but the right technique matters for comfort and effectiveness.
Site Selection
Trinza is given as an intramuscular (IM) injection into the gluteal muscleusually the upper outer quadrant to avoid the sciatic nerve. Rotate sides each time to reduce irritation.
Needle Choice
Most providers use a 21gauge, 1.5inch needle for the larger volumes. The needle length ensures the medication reaches deep muscle tissue, which is crucial for the depot effect.
Prep Steps
- Wash hands and wear gloves.
- Clean the injection site with an alcohol swablet it dry.
- Check the vials expiry date and shake gently if required.
- Insert the needle at a 90degree angle, aspirate briefly (most guidelines now say aspiration isnt needed for IM in the gluteus), then inject slowly.
- Withdraw the needle, apply gentle pressure, and cover with a sterile bandage if needed.
Even though youll likely have a nurse do the shot, knowing the steps helps you feel empowered and ask the right questions.
