Where do you inject GLP-1 medications?

The US labels for injectable GLP-1 medications list the abdomen, the thigh and the upper arm. For tirzepatide (Zepbound®, Mounjaro®), the labels say another person gives the upper-arm injection. The Instructions for Use with your pen or vial show exactly where.

Why rotate injection sites?

Most GLP-1 labels say to rotate sites with each dose. The liraglutide labels (Saxenda®, Victoza®) give a reason: “to reduce the risk of cutaneous amyloidosis”. Ask your prescriber or pharmacist how this applies to you.

Is the injection tracker free?

Yes. Print it, copy it and share it. No email address needed.

A GLP‑1 injection tracker with a body map.

A free, printable GLP‑1 injection tracker: a front and back body map of eight injection sites, a “last used” box for each, and a rotation log where you tick the site you used. Reading down a column shows how long each site has rested. It comes from Max HP, a GLP‑1 dose tracker for iPhone.

Page one of the injection site tracker: front and back body outlines with upper and lower abdomen, thighs and backs of the upper arms marked on both sides, then a table of the eight sites with columns for last used, before that and notes. — Page one: the body map and the last-used table. Page two is the rotation log.

How to use it

Check your medication’s Instructions for Use for which areas to use and exactly where. The label table quotes each one.
After each injection, write the date and dose on the rotation log and tick the site.
Note any redness, itching, a lump or a bruise, and how many days it lasted.
Update the last-used box for that site, so the next choice is quick.

The labels for Wegovy®, Zepbound®, Mounjaro® and Trulicity® say “Rotate injection sites with each dose.” The Zepbound® Instructions for Use add: “You may use the same area of your body but be sure to choose a different injection site in that area.” That’s why the sheet splits the abdomen into four.

The eight sites

Area	Sites on the sheet	Label note
Abdomen	Upper left, upper right, lower left, lower right	The Instructions for Use for Ozempic®, Zepbound® and Mounjaro® say at least 2 inches from the belly button
Thigh	Left, right	See the diagram in your Instructions for Use
Upper arm	Back of the left arm, back of the right arm	For tirzepatide, the labels say another person gives this injection

“Left” and “right” are always yours. The map is drawn as you see yourself, so your left is on the left.

What to record about a reaction

Injection-site reactions are listed in the labels. For each one, note:

the site and the date of the dose
what it looked or felt like: red, itchy, a lump, a bruise, pain
how big, roughly, and how many days it lasted
whether it keeps happening at the same site

Bring the log to your next appointment. If a reaction worries you, or it’s spreading, very painful or not getting better, contact your prescriber or pharmacist.

The same tracker in Max HP

Max HP has the same eight sites on a body map. Each one shows the days since you last used it, and the site you’ve rested longest is marked, so choosing is one tap. You can switch off sites you don’t use. Logging is free, with no account. More about injection sites⁠.
