GLP‑1 injection site rotation: a practical weekly routine

Introduction

Rotate the exact spot of each GLP‑1 injection, even if you use the same body region every week. U.S. instructions for semaglutide (Ozempic, Wegovy) and tirzepatide (Mounjaro, Zepbound) direct you to change sites; you do not need to cycle through every available body area. 1 2 3 4

Choose a site from your own device leaflet

These medicines go under the skin of approved areas of the abdomen, thigh, or upper arm. Use the diagram supplied with your device to identify the exact location. Mounjaro and Zepbound instructions say another person should give an injection into the back of your upper arm. 3 4

Wegovy instructions specify keeping abdominal injections 2 inches from the belly button. Do not assume all leaflets use identical wording: check the instructions for your particular pen or syringe. Our belly button injection guide explains those differences. 2

Pick a location you can see and reach while keeping the device steady. Ask for help with technique if you have to twist, strain, or change your grip during the injection. Reaching a different body region is optional; finding an appropriate spot is what matters.

Make a rotation plan you can describe

A workable plan might alternate left and right abdominal sites, or alternate thighs. Each time you return to a region, select a different spot within its approved area. The labels permit reuse of a body region while changing the site. 1 3

Use a brief note that you will understand next week, such as “left thigh, front” or “right abdomen, below last site.” Avoid relying on “stomach” alone if you tend to return to one small patch. Your pharmacist can help you make a map that matches your leaflet.

Check the planned location before preparing the shot. Choose another approved spot if the planned site looks irritated or feels sore.

Track rotation with Shotsy

Record your injection site and any soreness in Shotsy so you can review where you injected last. Your log can help you explain a recurring reaction to your clinician; it cannot assess skin health or measure medication absorption.

Conclusion

You can use the same approved body area each week, but choose a different injection spot each time. Before your next dose, check where you last injected. Record the new spot afterward so you can keep rotating without relying on memory.
