Injection Sites, Rotation, and What to Expect
Wegovy is supplied as a pre-filled pen and is injected subcutaneously — into the fatty tissue just beneath the skin. The three commonly used sites are the abdomen (at least a few centimetres away from the navel), the front of the thigh, and the outer upper arm. Each site can absorb the medicine effectively; the choice often comes down to personal preference and what is easiest to reach.
Why Rotation Matters
Rotating your injection site with each weekly dose helps protect the skin and tissue underneath. Repeatedly injecting into the same small area can lead to localised skin reactions or changes in the tissue over time. A simple rotation pattern — for example, cycling through abdomen, thigh, and arm across successive weeks, or moving to a different area within the same site — keeps each zone rested between doses.
What People Commonly Notice
Injection-site reactions such as mild redness, itching, or tenderness are among the most commonly reported experiences in the days after an injection. These are generally minor and short-lived for most people. If you notice anything persistent, spreading, or worrying at an injection site, contact your healthcare professional promptly. Any side effects worth noting — including injection-site reactions — can also be reported to your national pharmacovigilance scheme (such as the UK's Yellow Card scheme or the equivalent in your country).

How GLP Trackr Helps You Stay on Top of Your Wegovy Injections
Keeping a reliable record of each injection is one of the most practical things you can do on a weekly injection schedule — and it is where GLP Trackr is most directly useful for Wegovy users.
Automatic Injection-Site Rotation
Every time you log a dose, GLP Trackr records which site you used. Based on your history, the app suggests your next rotation site automatically, so you never have to remember where you last injected. Over time, you build a clear log of every shot — date, dose strength, and site — all in one place.
Dose Reminders
Because Wegovy is taken once a week, it can be surprisingly easy to lose track of where you are in your schedule. GLP Trackr's dose reminders keep your weekly routine on track with a gentle nudge, so a dose is not accidentally missed or doubled up.
Logging Side Effects to Discuss With Your Prescriber
If you experience injection-site reactions or any other symptoms after a dose, you can log them directly in the app. Having a clear, timestamped record of what you felt and when makes for a much more useful conversation at your next prescriber appointment than relying on memory alone. GLP Trackr is a tracking and journaling tool — it is not a substitute for your prescriber's advice, and any concerns about symptoms should always be discussed with your healthcare professional.
Ready to bring more consistency to your Wegovy routine? GLP Trackr is free to try for seven days on the App Store and Google Play — log your first injection, set a reminder, and let the app handle your rotation from there.

Frequently asked questions.
Wegovy is injected subcutaneously into one of three sites: the abdomen (away from the navel), the front of the thigh, or the outer upper arm. Your prescriber or doctor will have confirmed the right approach for you when Wegovy was first prescribed.
Yes. Rotating the injection site each week — cycling through the abdomen, thigh, and upper arm, or moving within the same area — helps protect the skin and tissue. Using the exact same spot repeatedly can cause localised skin changes over time.
Mild redness, itching, or tenderness at the injection site are commonly reported and usually short-lived. If a reaction is persistent, spreading, or causes concern, contact your healthcare professional promptly rather than waiting for your next appointment.
GLP Trackr logs every injection site you record and automatically suggests your next rotation. This removes the guesswork from your weekly routine and gives you a complete history of every dose and site at a glance.
Always follow the guidance of your prescriber or doctor — they know your full medical history. For anything worrying, contact your healthcare professional promptly. Side effects can also be reported to your national pharmacovigilance scheme, such as the UK's Yellow Card scheme or the equivalent service in your country.
