# Injection site rotation: what to record.

By [Max HP](https://maxhp.me/about) · Updated 3 November 2026

The labels for injectable GLP-1 medications say where a dose goes and, for most of them, that sites rotate. What they do not do is remember where last week’s dose went. Here is what a useful site record contains, and how to make the choice without turning it into a rule.

## What the labels say

The US prescribing information for each injectable GLP-1 medication lists the same three broad areas: the abdomen, the thigh and the upper arm. The wording around rotation is less uniform. Four labels say to rotate with each dose. The two liraglutide labels say to rotate within the same region. The Ozempic® label gives the sites but, in the text read for this article, no rotation sentence.

| Medication | Where the label says to inject | What it says about rotation |
|---|---|---|
| [Ozempic®](https://dailymed.nlm.nih.gov/dailymed/drugInfo.cfm?setid=adec4fd2-6858-4c99-91d4-531f5f2a2d79) semaglutide, weekly | “Inject OZEMPIC subcutaneously in the abdomen, thigh, or upper arm.” | No rotation sentence in the prescribing information text read |
| [Wegovy®](https://dailymed.nlm.nih.gov/dailymed/drugInfo.cfm?setid=ee06186f-2aa3-4990-a760-757579d8f77b) semaglutide, weekly | “Inject WEGOVY subcutaneously in the abdomen, thigh, or upper arm.” | “Rotate injection sites with each dose.” |
| [Zepbound®](https://dailymed.nlm.nih.gov/dailymed/drugInfo.cfm?setid=487cd7e7-434c-4925-99fa-aa80b1cc776b) tirzepatide, weekly | “Inject ZEPBOUND subcutaneously in the abdomen, thigh, or another person should inject in the back of the upper arm.” | “Rotate injection sites with each dose.” |
| [Mounjaro®](https://dailymed.nlm.nih.gov/dailymed/drugInfo.cfm?setid=d2d7da5d-ad07-4228-955f-cf7e355c8cc0) tirzepatide, weekly | “Inject MOUNJARO subcutaneously in the abdomen, thigh, or have another person inject MOUNJARO in the back of the upper arm.” | “Rotate injection sites with each dose.” |
| [Trulicity®](https://dailymed.nlm.nih.gov/dailymed/drugInfo.cfm?setid=463050bd-2b1c-40f5-b3c3-0a04bb433309) dulaglutide, weekly | “Inject TRULICITY subcutaneously in the abdomen, thigh, or upper arm.” | “Rotate injection sites with each dose.” |
| [Saxenda®](https://dailymed.nlm.nih.gov/dailymed/drugInfo.cfm?setid=3946d389-0926-4f77-a708-0acb8153b143) liraglutide, daily | “Inject SAXENDA subcutaneously in the abdomen, thigh, or upper arm.” | “Rotate injection sites within the same region in order to reduce the risk of cutaneous amyloidosis” |
| [Victoza®](https://dailymed.nlm.nih.gov/dailymed/drugInfo.cfm?setid=5a9ef4ea-c76a-4d34-a604-27c5b505f5a4) liraglutide, daily | “Inject VICTOZA subcutaneously in the abdomen, thigh or upper arm.” | “Rotate injection sites within the same region in order to reduce the risk of cutaneous amyloidosis” |

Quoted from the current US prescribing information on DailyMed, read in November 2026. Labels change; the links go to the current text. Compounded semaglutide and tirzepatide do not have a label of this kind. The Zepbound® sentence is reproduced as printed in the label.

## What rotating means

The tirzepatide patient instructions put the idea simply: “You may use the same area of your body but be sure to choose a different injection site in that area.” That is one kind of rotation: stay in the abdomen, but move a few centimeters from the last spot. The liraglutide labels describe the other kind, moving around within the same region rather than jumping between the abdomen, thigh and arm.

The labels do not define a map or a fixed order. They give a reason for the instruction where they can. The Saxenda® and Victoza® labels name cutaneous amyloidosis, a skin change that can follow repeated injections into the same place. The point is not ceremonial. Changing the spot gives the skin under the last one time to recover.

Rotation is an injection technique, not a treatment decision. It does not change the dose. It does not make the medication work faster or slower. If a site is painful, bruised or difficult to use, the answer is not to force it; it is to use another site the label allows and mention the problem at your next contact with your prescriber or pharmacist.

## What to record after each dose

- **The date and the dose**: Not a schedule or a target: the amount you actually took, on the day you took it. Dose and date are the two facts every later question depends on.

- **The site, in your own terms**: “Left lower abdomen” is enough. If you use a body map, the same information becomes a shape you can see rather than a sentence you have to reconstruct.

- **Which side**: Left and right are easy to mix up a week later. Your own left is the left side of the map, whether you are looking at the front or the back.

- **What the skin looked like**: A small red mark, a raised lump, a bruise, an itch. Record it when it appears, not when it fades, and note how long it lasted.

- **Anything that made the dose unusual**: A different pen, a new pharmacy, a dose given by someone else. These details are hard to remember at an appointment and easy to write down at the time.

## A record, not a rule

Max HP draws eight sites on a front and back body map: four on the abdomen, two on the thighs and two on the upper arms. Each site shows the days since it was last used, so the choice is visible rather than remembered. The app marks the site rested longest as a suggestion. It is only a suggestion; any site the label allows can be tapped instead.

If your prescriber or pharmacist rules out a site, turn it off in the app and Max HP stops suggesting it. If you use a pen, the Instructions for Use show the exact areas and the angle for your device. Those instructions come with the medication for a reason. A log can remember where you went; it cannot tell you how to inject.

A site record does not need a plan for the next six months. It needs the last few doses, accurately placed. The pattern will emerge: a site that bruises, a side that is easier to reach, a spot that stays sore. Those are practical observations, and they are more reliable than a rule invented in advance. If the pattern suggests a problem, the record gives your prescriber something concrete to look at. The record also makes the next choice quicker: a glance at the last few sites is faster than a mental replay of the month, and a small habit with a long memory.

## Questions

**Do GLP-1 labels say to rotate injection sites?**

Most of them do. The Wegovy®, Zepbound®, Mounjaro® and Trulicity® labels say “Rotate injection sites with each dose.” The Saxenda® and Victoza® labels say to rotate within the same region. The Ozempic® prescribing information text read for this article lists the sites without a rotation sentence. Your prescriber or pharmacist can show you what applies to your medication.

**Does the injection site change how the medication works?**

The labels report similar exposure across the allowed areas. The Zepbound® label says “Similar exposure was achieved with subcutaneous administration of tirzepatide in the abdomen, thigh, or upper arm.” The choice of site is about technique and comfort, not about adjusting the dose.

**Which sites do the labels list?**

The abdomen, the thigh and the upper arm. For Zepbound® and Mounjaro®, the upper-arm site is the back of the arm and the label says another person gives that injection. The Instructions for Use for your pen or vial show the exact areas.

**What if I cannot remember where I injected last week?**

Write down what you do remember, including the area and the side if you can, and start recording from the next dose. A log does not need a perfect past to be useful. It needs enough detail that the next choice is not a guess.
