Mounjaro: How to inject using the pre-filled pen

Mounjaro is used to manage blood sugar in adults with type 2 diabetes, together with diet and exercise.

It’s available as single-dose pens (also called an autoinjector) and single-dose vials. It comes in six different doses, and is injected once a week under the skin. Mounjaro is a GIP and GLP-1 receptor agonist.

If you have been prescribed Mounjaro, the brand name for tirzepatide, you should have received training from your healthcare professional on how to give yourself the injection safely.

In this video, we will review step-by–step how to give yourself a Mounjaro injection using the pre-filled pen.

Before using Mounjaro, review the Instructions for Use provided with your prescription. When you are ready to inject your dose, gather your materials.

You will need: Your Mounjaro pen, a piece of gauze or a cotton ball, an alcohol swab, and a sharps container.

Now that you are ready to inject your dose, let’s review the steps on how to inject your Mounjaro pen.

Step 1: Check your pen to make sure the medication isn’t expired, frozen, or cloudy. It should look colorless to slightly yellow, and shouldn’t have particles in it.

Step 2: Wash your hands with soap and water.

Step 3: Choose your injection site. If you are injecting Mounjaro by yourself, you can inject it into your stomach, 2 inches away from your belly button, or into your thigh. If someone else is helping you, they can inject it into the back of your upper arm. Make sure to change your injection site each week. Clean your chosen injection site with an alcohol swab.

Step 4: While the pen is locked, pull off the gray base cap and throw it away.

Step 5: Place the clear base flat against your skin at the injection site, then twist the top of the pen to the “unlocked” position.

Step 6: While holding the pen firmly against your skin, press and hold the purple injection button for up to 10 seconds. You will hear a click signaling the injection has started, and a second loud click when the injection is completed. The injection is done when you can see the gray plunger.

Step 7: Remove the pen from your skin and place it directly into a sharps container.

Step 8: If you have any bleeding at the injection site, you can press a cotton ball or gauze over the injection site until the bleeding has stopped.

If you have any questions about how to inject Mounjaro, contact your healthcare provider or the manufacturer, Lilly.
