Mounjaro is administered as a once-weekly subcutaneous injection. There are several approved injection areas, which raises a common question: should Mounjaro be injected in the stomach, thigh or upper arm?

Where can Mounjaro be injected?

According to the official instructions, Mounjaro can be injected under the skin of the abdomen, thigh or back of the upper arm.

When using the back of the upper arm, another person may help administer the injection correctly.

Is the stomach better than the thigh?

The official instructions do not identify one of these approved areas as the best location for everyone. The abdomen, thigh or upper arm can be used as directed.

Should the injection site be changed?

Yes. The injection site should be rotated with each weekly dose. You can continue using the same general body area while choosing a different spot within that area.

Can Mounjaro and insulin be injected in the same area?

If both medicines are prescribed, they can be injected in the same general body region, but the injections should not be given directly next to each other and the medicines should not be mixed together.

Is Mounjaro injected into a muscle or vein?

No. Mounjaro is intended for subcutaneous injection and should not be injected into a muscle or vein.

Conclusion

Mounjaro can be injected under the skin of the abdomen, thigh or back of the upper arm. Rotating the injection site and following the correct administration technique are important parts of treatment.
