GuideGLP-1 Injection Site Rotation and How to Keep a Log
In this guide

The medication’s patient information lists the stomach area, the thigh and the upper arm as places to inject semaglutide, and it says to use a different site for each injection. Rotating means you do not return to the same spot every week. The easiest way to follow that advice is to write down where each shot went. This guide covers the idea and a simple logging habit. Your prescriber or pharmacist should show you the technique itself.

Where the patient information says to inject
MedlinePlus, which summarizes the official drug information, names the upper arm, thigh or stomach area for semaglutide injection and tells people to use a different site each time. Other GLP-1 pens have their own instructions. Read the leaflet that comes in your box and ask the person who prescribed it to show you in person the first time.
Why rotating sites is commonly advised
The official instructions simply say to use a different site each time. Your prescriber or pharmacist can explain the reasoning and what to watch for if a spot looks or feels unusual. Report anything that worries you, such as a lump that does not go away, spreading redness, or significant pain.
A simple rotation pattern
There is no single correct pattern, so use one you will actually follow. Here are two common ways people think about it.
Rotate by body area
Move between the left and right stomach area, the left and right thigh, and the left and right upper arm, one place per week. After six weeks you are back at the start. Within one area, ask your pharmacist how far to move from the last spot.
Rotate by side
If you stick to one body area, alternate left and right and keep moving the exact point. Either works. What matters is that you can tell where the last shot went.
What to log each time
A log answers “where did I go last week?” in a few seconds. Record:
- Date and time of the shot.
- Site, such as left thigh or right stomach area.
- Dose as prescribed, in the units on your pen.
- Anything unusual at the site, such as redness, a bump or bruising.
- A short note on how you felt in the next day or two.
Over several weeks this also helps your appointments, because you can show your prescriber an accurate history rather than guess.

Frequently asked questions
Does it hurt more in some places?
People report different experiences. Ask your prescriber or pharmacist for technique tips, since they can watch you inject.
What if I forget where my last shot went?
Choose a spot that looks fine and is away from recent ones, then start logging so it does not happen again. If you are unsure about the site, ask your pharmacist.
Can I use the same site if a spot bruises?
A bruise or lump is worth mentioning to your prescriber. In the meantime, a different site avoids the sore area.
Do injection site rules differ by medication?
They can. Check the patient information for your specific pen, since this article is general.
