Mounjaro Injection Sites

I am not a doctor, nor pretend to play one on the internet. Always talk with your own healthcare professionals. This is not medical advice. Updated: January 24, 2025 // Published: September 19, 2024 // Written by: Elizabeth Skordinski

There are 3 Mounjaro injection sites:

Stomach by belly button
Thigh
Back of Arm

Proper Injection Technique: Remove the Mounjaro injection pen from the carton for your dose of Mounjaro. Take off the gray base cap. Twist the unlocking system.

When injecting, push the purple injection button and you will hear the first click. Hold the gray plunger for up to 10 seconds and you will hear a second click. You can remove the pen from your skin. Mounjaro injections are subcutaneous injections.

You may see left over medication from the single-dose pen. You skin may or may not have blood. This is all normal for your weekly injections.

Recommended starting dosage of Mounjaro is Mounjaro 2.5mg. When you think you want to titrate up doses, talk to your healthcare provider to make an informed decision about next steps for your Mounjaro treatment dose.

Injection Sites For Mounjaro

Eli Lilly is the manufacturer of Mounjaro. Eli Lilly’s literature for Mounjaro states that injections should rotate on the three best injection sites for Mounjaro.

For the first month and a half, I simply injected only into my stomach and rotated stomach locations.

If it is/was working, I did NOT want to add too many variables by changing injection location.

It took me months to learn where the best possible results were for maximum appetite suppression.

Where To Inject Mounjaro?

Where to inject Mounjaro? Using Eli Lilly’s literature that comes in the package the purple injection sites on the upper thigh, back of the upper arms and near the belly belly button.

Eli Lilly tells us in the literature to rotate injection sites.

My Mounjaro injection site rotation schedule I use or different areas of the body:

Left side of belly button on the stomach
Left upper arm on the back of the arm
Left thigh
Right injection site of stomach injection sites
Right back of arm
Right thigh

Mounjaro Injection Site

And with the 6 injection sites rotation, I would then start over.

Then, I started to incorporate using top, bottom, left right for a specific side and ended up getting 24 injection sites!

TOP: Left side of belly button on the stomach
TOP:Left back of arm
TOP: Left thigh
TOP: Right side of belly button on the stomach
TOP: Right back of arm
TOP: Right thigh
BOTTOM: Left side of belly button on the stomach
BOTTOM:Left back of arm
BOTTOM: Left thigh
BOTTOM: Right side of belly button on the stomach
BOTTOM: Right back of arm
BOTTOM: Right thigh
LEFT SIDE OF: Left side of belly button on the stomach
LEFT SIDE OF:Left back of arm
LEFT SIDE OF: Left thigh
LEFT SIDE OF: Right side of belly button on the stomach
LEFT SIDE OF: Right back of arm
LEFT SIDE OF: Right thigh
RIGHT SIDE OF: Left side of belly button on the stomach
RIGHT SIDE OF:Left back of arm
RIGHT SIDE OF: Left thigh
RIGHT SIDE OF: Right side of belly button on the stomach
RIGHT SIDE OF: Right back of arm

Used Pen: When you are done with the single-dose injection pen, dispose of your pen in a FDA-cleared sharps disposal container. My favorite sharps container I use:

And then restart this process over….so my body is continuously having a change each injection week. I discuss in my Dark Side Of Mounjaro video more about why I believe so strongly in rotating injection sites:

This depends on your schedule, work commitments, family commitments and preferences. Should you take Mounjaro in the Morning or Evening? (READ MORE HERE)

Mounjaro Stomach Injection

For all Mounjaro injections, always use the diagram in the Mounjaro packaging for where to specifically inject on your body.

When I started taking Mounjaro 2.5mg, I initially only did my Mounjaro injection in my stomach by my belly button.

I continued the Mounjaro injection in my stomach by my belly button for weeks too afraid to rotate to my arm or thigh.

After several months, I got the courage to try injecting Mounjaro into thigh.

Injecting Mounjaro In Thigh

Injecting Mounjaro in thigh was not painful for me at all. In fact, I questioned why I had waited so long to inject Mounjaro into my thigh.

I do notice I have side effects when I rotate locations. And Mounjaro side effect I didn’t necessarily have before, I did when I rotated locations.

This helped with Mounjaro side effects. (For Mounjaro side effect solutions, READ MORE HERE.)

Mounjaro Arm Injection

Another person is going to inject your Mounjaro arm injection since the injection is the upper, back part of your arm.

When the Count gives my arm injection, I countdown “3,2,1…go” and then he pushes the Mounjaro pen plunger.

The Mounjaro pen makes two clicking sounds.

I count for twenty seconds to remove the Mounjaro pen off my skin.

Mounjaro Side Effects:

Here are the most common Mounjaro side effects from Mounjaro.com. Of course everyone can experience different side effects.

Personally, just because I had one Mounjaro side effect at one dose didn’t mean I was going to have it for all doses.

Nausea
Diarrhea
Decreased appetite
Vomiting
Constipation
Indigestion
Stomach Pain

Always talk with your doctor if you are having a common side effect, symptoms of a serious allergic reaction, abdominal pain or if your family has a history or thyroid cancer.

And the inverse for me is true too. Just because I didn’t experience one side effect on one dose didn’t mean I didn’t have that side effect at a higher dose when I titrated up.

Mounjaro Nausea

If you can nausea on Ozempic or Mounjaro nausea, some tips to help from Ozempic.com:

Eat bland diet like crackers or toast
Get fresh air

Avoid sugary foods

Mounjaro 2.5mg Weight Loss

Sharps Container – You will need somewhere to dispose of your Mounjaro, Wegovy or Ozempic syringe after injecting it. I love this container, but it’s smaller to fight underneath your bathroom sink, but large enough to fit the Mounjaro injection afterwards. SHOP HERE Biohazard Needle & Syringe Disposal

Alcohol Prep Pads

Alcohol Prep Pads For Injection Site – I didn’t realize prior to my Mounjaro injections that I should make sure my injection site was clean with an alcohol pads. I love these because they are so little I can easily store them with my other Mounjaro items. SHOP HERE.
