Wegovy Injections: What to Know About Sites, Rotation, and Getting It Right

Wegovy is injected into the fatty tissue just beneath the skin — a subcutaneous injection. The three most commonly used areas are the abdomen (at least a few centimetres away from the navel), the front of the upper thigh, and the back or outer part of the upper arm. Your prescriber or doctor will confirm which sites are suitable for you personally.

Why rotating injection sites matters

Using the same spot repeatedly can cause localised skin changes such as lumpiness or thickening (lipohypertrophy), which may affect how well the medicine is absorbed. Rotating between different areas — and moving to a different part of the same area each week — helps keep skin tissue healthy. Many people find it easy to lose track of where they last injected, especially across multiple weeks and sites, which is where a reliable log becomes useful.

"I didn't feel the injection" — is that normal?

Subcutaneous injections through a fine-gauge needle are often barely noticeable. Not feeling a sensation during the injection is common and does not mean the dose was not delivered. If you are ever genuinely unsure whether a full dose was administered, check the Patient Information Leaflet that came with your pen and speak with your prescriber or pharmacist — never attempt an additional dose without their guidance.

"I think I made a mistake with my injection"

If you believe something went wrong — for example, the pen did not click, or you injected into an unintended area — consult your prescriber or doctor before taking any further action. Do not attempt to repeat or supplement the dose on your own. Logging exactly what happened, including the time, site, and any observations, gives your prescriber the clearest possible picture when you speak to them.

You may also find it helpful to read about choosing and managing Wegovy injection sites in more detail, or explore how Mounjaro injections compare if you have questions about the two medicines.

According to guidance published on the electronic Medicines Compendium, Wegovy pens should be stored in a refrigerator before first use — always check the leaflet included with your pen for full storage and handling instructions, as conditions can affect the medicine.

Staying on top of a weekly injection schedule across rotating sites is straightforward in theory but easy to lose track of in practice — especially over months of treatment. GLP Trackr's injection-site tracking is built precisely for this: each time you inject, you log the site (abdomen, thigh, or arm) and the app keeps a running history, suggesting which area to use next so rotation becomes automatic rather than something you have to remember.

Alongside site tracking, the dose logging feature records the date, time, and dose strength of every injection in one place — so you always have a clear, timestamped record of where you are in your treatment. And if a weekly reminder helps you stay on schedule, GLP Trackr can send a gentle nudge so a dose is never forgotten.

That log is also genuinely useful beyond the app itself: if you ever need to discuss your injection history with your prescriber — whether about a missed dose, a site reaction, or simply a check-in — you can bring a clear summary to your appointment rather than relying on memory.

Any concerns about your dose, injection technique, or whether a dose was delivered correctly should always be discussed with your prescriber or doctor. GLP Trackr records your journey and helps you have better-informed conversations — it is not a substitute for clinical guidance. For any side effects that feel severe or persistent, contact your healthcare professional promptly. You can also report unexpected reactions to your national reporting scheme (such as the UK's Yellow Card scheme) and to your prescriber.
