Administering your Mounjaro (tirzepatide) injection correctly is essential for its effectiveness and your safety. Here's a step-by-step guide to help you through the process:

*** UK PENS AND AUSTRALIAN ARE THE SAME ***

Step 1: Prepare for Your Injection

  • Check your prescription to ensure you have the correct pen strength.

  • Remove the pen cap and inspect the liquid in the window.

    • It should be clear and colorless.

    • Do not use if it is cloudy, frosty, or contains particles.

  • Gather the necessary items:

    • Mounjaro Pen

    • New needle

    • Alcohol swab

    • Sharps container (for needle disposal)

      Step 2: Attach a New Needle

      • Take a new needle from the pack.

      • Remove the paper cover from the needle.

      • Push the needle onto the pen securely.

      • Twist the needle until it is firmly in place.

      • Remove the plastic cap from the needle.

      Step 3: Prime the Pen (Before Every Dose)

      • Twist the dose selector until the first long line appears in the treatment window.

      • Press the dose button.

      • Repeat this process until a small droplet of liquid appears at the needle tip.

      Step 4: Select Your Dose

      • Twist the dose selector until the number 1 appears in the treatment window.

      • This confirms that the pen is ready for injection.

      Step 5: Choose an Injection Site

      • You can inject Mounjaro into:

        • The front of the thigh

        • The abdomen (at least 2 inches away from the belly button)

        • The top of the arm (if administered by someone else)

      • Avoid injecting into a muscle.

      • Clean the chosen area.

      Step 6: Administer the Injection

      • Pinch the skin gently at the injection site.

      • Insert the needle at a 90° angle.

      • Push the plunger all the way until the number 0 appears in the treatment window.

      • Hold the needle in place for 10 seconds to ensure the full dose is administered.

      Step 7: Dispose of the Needle

      • Remove the needle carefully.

      • Place the plastic cap back on the needle.

      • Unscrew the needle from the pen and dispose of it in a sharps container.

      Step 8: Store Your Mounjaro Pen

      • Place the pen cap back on.

      • Store the pen in the refrigerator if possible.

      • If refrigeration isn’t available, store it in a cool, dry place at room temperature (max 21 days)

      • Do not freeze the pens

      • Your next injection will be in 7 days.

      Important Notes

      • Always follow your clinician’s instructions for dosage and injection techniques.

      • Never share your Mounjaro Pen with anyone else.

      • If you have any questions or concerns, contact your healthcare provider for guidance.

Additional Tips:

  • Missed Dose: 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 your regular schedule. Do not take extra medicine to make up for the missed.
