Where to inject Wegovy
Abdomen
Wegovy can be injected under the skin of your abdomen. Choose a different spot in the abdomen area each time to reduce irritation. Your clinician or pharmacist can show you what site rotation looks like for you.
Thigh
The thigh is another labeled option for Wegovy injections. Rotating within the thigh area can help avoid injecting into the exact same spot repeatedly. Use the Instructions for Use for the pen-specific guidance.
Upper arm
Wegovy may also be injected into the upper arm. Many people need help reaching the back of the upper arm, so ask your clinician or pharmacist what is practical and safe. Rotate sites week to week.
How to inject safely (label basics)
It is a subcutaneous injection
Wegovy is injected under the skin (subcutaneous). It is not meant to be injected into a vein or muscle. If you are unsure what “under the skin” means, ask your pharmacist or prescribing clinician to demonstrate.
Rotate injection sites
The Instructions for Use advise rotating your injection site with each dose. Rotating helps lower the chance of soreness and skin irritation. You can rotate within one area (such as the abdomen) or alternate between areas, based on what you can do reliably.
Use once weekly, same day
Wegovy is intended for once-weekly use. The label advises choosing the same day each week, and you can change the day if needed as long as enough time has passed between doses. Your prescriber should guide any schedule changes.
Follow your product’s instructions
Wegovy is a prefilled, single-dose pen, and the manufacturer provides pen-specific Instructions for Use. If you are using compounded semaglutide instead of Wegovy, your dispensing pharmacy and clinician provide the instructions for that formulation.
| Injection site (label) | What it means for you | What to do |
|---|---|---|
| Abdomen | A labeled option many people can access easily. | Rotate spots each dose and follow the Instructions for Use. |
| Thigh | A labeled option that may be easier for self-injection for some. | Rotate within the thigh area and use clinician guidance if you have questions. |
| Upper arm | A labeled option that may require assistance to reach safely. | Ask a clinician or pharmacist to show you, and rotate sites. |
When to talk to a clinician
You are unsure about sites
If you cannot comfortably reach an injection site or you are not sure which area you should use, ask your prescribing clinician or pharmacist to demonstrate. This is especially important if you have limited mobility or reduced sensation.
Skin reactions keep happening
Mild redness or soreness can happen with injections, but persistent, worsening, or severe reactions should be discussed with a clinician. They can help you review rotation, technique training, and whether another site is better for you.
You may have taken too much
If you think you took more than prescribed, contact Poison Control or get emergency help right away. The Wegovy label warns that overdose can cause severe nausea, severe vomiting, and severe low blood sugar.
You have severe symptoms
Get urgent medical care for symptoms that could signal a serious problem, such as severe abdominal pain that may radiate to the back (with or without vomiting). The Wegovy prescribing information lists pancreatitis as a serious risk that needs prompt evaluation.
Pro tips for injection day
Pick a repeatable routine
Choose a weekly day you can stick with, then rotate the site each dose.

Ask for a demo once
A pharmacist or clinician can show you site rotation and safe handling.
