Mounjaro (tirzepatide) is a prescription medication used to help manage blood sugar levels in adults with type 2 diabetes. Recently, it has also gained attention for its effectiveness in supporting weight loss in patients with obesity or weight-related health conditions. Administered as a once-weekly subcutaneous injection, Mounjaro is easy to use when done correctly. Whether you're new to injectable medication or just need a refresher, understanding how to properly use Mounjaro injection instructions is key to ensuring safety and effectiveness.
What You’ll Need
Before getting started, make sure you have the following:
A Mounjaro pre-filled pen (dose as prescribed by your doctor)
Alcohol swabs
A sharps disposal container
Store Mounjaro pens in the refrigerator, but allow the pen to sit at room temperature for 30 minutes before injection. Do not freeze the pen, and never use it if it has been frozen.
Step-by-Step Injection Instructions
1. Wash Your Hands
Start by washing your hands thoroughly with soap and water to reduce the risk of infection.
2. Choose an Injection Site
You can inject Mounjaro into:
The front of your thighs
Your abdomen (at least 2 inches away from your navel)
The back of your upper arms (if administered by someone else)
Rotate injection sites with each dose to avoid skin irritation.
3. Clean the Area
Use an alcohol swab to clean the selected injection site. Allow the area to air dry completely before injecting.
4. Prepare the Pen
Remove the pen cap and inspect the medication. The liquid should be clear and colorless. Do not use the pen if the solution is cloudy or contains particles.
Turn the base of the pen until you hear a click and the dose window displays your prescribed dose.
5. Inject the Medication
Place the pen firmly against the skin at a 90-degree angle. Press and hold the injection button. You’ll hear a click — continue to hold the pen in place for about 10 seconds to ensure the full dose is administered.
6. Remove the Pen
After the injection is complete, remove the pen from your skin. Do not rub the injection site. Dispose of the used pen in a FDA-cleared sharps container.
7. Store Remaining Pens
Store unused pens in the refrigerator. Once a pen is out of the fridge, it can be stored at room temperature (up to 30°C or 86°F) for 21 days.
Additional Tips
Take your injection on the same day each week, at any time of day, with or without food.
If you miss a dose and it’s been less than 4 days, take it as soon as possible. If more than 4 days have passed, skip the missed dose and resume on your next scheduled day.
Do not share your pen, even if the needle has been changed.
Final Thoughts
Using Mounjaro correctly is vital for getting the most out of your treatment. If you ever feel unsure about the injection process, consult your healthcare provider or pharmacist for guidance. With proper use and support, Mounjaro can be a powerful tool in managing type 2 diabetes and supporting weight loss efforts.
