You self-inject Mounjaro once a week (on the same day each week), under your skin, in the subcutaneous fat. Don’t worry, the needle is very small, and most patients describe it as a pin-prick feeling. When you inject Mounjaro, you should always follow the instructions and make sure you’re in a safe, clean environment.

Prepare for the injection

• Wash your hands with soap and water before preparing your pen.
• Check the solution inside the pen is colourless or slightly yellow.
• Wipe the red inner seal with a swab.
• Attach the needle and remove both needle caps safely.

Only use this medication if the solution is colourless or slightly yellow. If the solution is cloudy or you can see various particles, discard it and speak to your doctor. Never reuse or share needles with others.

Check the flow

• Dial your Mounjaro pen to the flow check symbol.
• You will need to complete this step each time you inject a dose.
• Hold your pen horizontally with the needle pointing upwards.
• Press the dose button until the pointer is lined up with “0 mg”.
• At this point, a drop of solution will appear at the tip of your needle.

If the solution does not appear at the needle tip, repeat these steps up to two more times. If the solution still does not appear, do not use the pen and contact your healthcare provider.

Select your dose

• Turn the dial until it stops and the number 1 is shown in the dose window.
• Do not inject more than your prescribed dose. Always follow your healthcare professional’s instructions.

Inject your dose

• Insert the needle into your abdomen, upper arm or thigh.
• Press and hold the dose button to administer the solution until the pointer is aligned with “0 mg.”
• Keep holding the dose button for an additional 5 seconds to ensure the dose is fully administered.
• Gently remove the injection.
• Do not release the dose button until the needle has been removed from your skin.

Only inject into the areas mentioned in the patient information leaflet (abdomen, thigh and upper arm). Make sure to rotate the injection site with each dose to avoid discomfort.

Discard your needle

• Carefully attach the outer needle shield back on the needle and remove your needle from the pen.
• Dispose of the needle in the yellow sharps bin provided.
• Do not throw your used needles away in your household rubbish bin. Keep them out of reach of children and pets.

Store your Mounjaro pen

• After every use, be sure to place the pen’s cap back on. This protects the medication from light.
• You should store your pen without needles attached.
• Store Mounjaro for up to 30 days at room temperature (so long as this is not above 30˚C) or in a refrigerator cooling element (2˚C to 8˚C.)
• Ensure this medication is stored somewhere others cannot reach it, particularly children and pets.
