Mounjaro Guide

Step 1: Wash your hands with soap and water.


Step 2: Pull the pen cap straight off. And inspect the pen and label.
Do not use if:

  • the medication name or dose strength does not match your prescription.
  • the pen is expired (EXP) or looks damaged.
  • the medication has been frozen, has particles, is cloudy, or is discoloured.

Please note: Mounjaro should be colourless to slightly yellow.


Step 3: Wipe the red inner seal with a swab.


Step 4: Select a new pen needle. Always use a new pen needle for each injection to help prevent infections and blocked needles. Pull off the paper tab from the outer needle shield.


Step 5: Push the capped pen needle straight onto the pen and twist the pen needle on until it is tight.


Step 6: Pull off the outer needle shield and keep it. This will be reused. Then pull off the inner needle shield and Put it in your household bin.


Step 7: Slowly turn the dose knob until you hear 2 clicks and the extended line is shown in the dose window. This is the prime position. It can be corrected by turning the dose knob in either direction until the prime position lines up to the dose indicator.


Step 8: Hold your pen with the needle pointing up. Tap the cartridge holder gently to collect air bubbles at the top.


Step 9: Release some medicine into the air by pushing the dose knob in until it stops, then slowly count to 5 while holding the dose knob. The icon must be shown in the dose window. Do not inject into your body. Priming removes air from the cartridge and makes sure that your pen is working correctly. Your pen has been primed if a small amount of medicine comes out of the tip of the pen needle.


Step 10: Choose an injection site. You or another person can inject the medicine in your thigh or stomach (abdomen) at least 5 centimetres from the belly button. Change (rotate) your injection site each week. You may use the same area of your body but be sure to choose a different injection site in that area.

Step 10: Choose an injection site. You or another person can inject the medicine in your thigh or stomach (abdomen) at least 5 centimetres from the belly button. Change (rotate) your injection site each week. You may use the same area of your body but be sure to choose a different injection site in that area.


Step 11: Turn the dose knob until it stops and the one icon is shown in the dose window. The one icon is equal to the dose you require. It delivers 0.6ml of liquid which has the correct dose of the pen you are using. For example if you are using a 2.5mg pen, the one icon will deliver one dose of 2.5mg.


Step 12: Insert the needle into your skin and inject the medicine by pushing the dose knob in until it stops then slowly count to 5 while holding the dose knob. The zero icon must be shown in the dose window before removing the needle.


Step 13: Pull the needle out of your skin. A drop of medicine on the needle tip is normal. It will not affect your dose. • Confirm the zero icon is in the dose window. If you see the zero icon in the window, you have received the full dose. If you do not see the zero icon in the dose window, insert the needle back into your skin and finish your injection. Do not redial the dose. If you still do not think you received the full dose, do not start over or repeat the injection. Contact us and we’ll be able to help you troubleshoot the issue.


Step 14: If you see blood after you pull the needle out of your skin, this is normal, lightly press the injection site with gauze or a cotton ball. Do not rub the injection site.


Step 15: Carefully replace the outer needle shield.


Step 16: Unscrew the capped needle and put the needle in a sharps container. Do not store the pen with the needle attached to prevent leaking, blocking the needle, and air from entering the pen.


Step 17: Replace the pen cap and store it safely until your next injection.
