Understanding Subcutaneous Injections
Wegovy (semaglutide) is a medication delivered via subcutaneous injection, meaning it is injected into the layer of fatty tissue just under the skin, not into a muscle or vein. The medication comes in a prefilled, single-dose pen for self-administration. For proper effectiveness and comfort, it's essential to use the correct technique and approved injection sites.
Recommended Wegovy Injection Sites
The manufacturer and healthcare providers recommend three primary areas for injection.
1. The Abdomen
The abdomen is often chosen for its accessibility and subcutaneous fat. Inject into the lower part of the stomach, at least two inches away from the belly button. Standing may help create a firmer surface. Inject perpendicular to the skin without pinching. Avoid areas near the waistline.
2. The Upper Thigh
The upper thigh is another convenient and effective site with good fatty tissue for absorption. Inject into the front or outer part, halfway between the hip and knee. You can sit or stand. Avoid the inner thigh.
3. The Upper Arm
The upper arm is a suitable alternative but can be hard to reach alone. Inject into the back or side, between the shoulder and elbow. Assistance may be needed. For lean individuals, pinching skin can help ensure injection into fatty tissue.
Importance of Rotating Injection Sites
To prevent bruising, irritation, scarring, or hard lumps that affect absorption, rotate your injection site weekly. Use a different body area or a new spot within the same area, at least one inch from the last site. Tracking sites helps remember to switch.
Where to Avoid Injecting Wegovy
Never inject into skin that is tender, bruised, red, hard, scarred, or has stretch marks. For abdominal injections, avoid areas within two inches of the navel.
Comparison of Wegovy Injection Sites
| Feature | Abdomen | Upper Thigh | Upper Arm |
|---|---|---|---|
| Accessibility | Very high | High | Low for self-injection |
| Comfort/Pain | Often less painful | Generally comfortable | Can be less comfortable for some |
| Absorption | Equally effective | Equally effective | Equally effective |
| Subcutaneous Fat | Typically large area | Good layer | Varies; may need pinching for lean individuals |
How to Perform a Wegovy Injection
- Prepare: Gather pen, alcohol swab, and sharps container. Wash hands.
- Inspect: Check expiration and medication clarity (should be clear and colorless). Air bubbles are normal. Do not use if cloudy, discolored, or frozen.
- Choose and Clean: Select a new site following rotation. Clean with an alcohol swab and let dry.
- Inject: Remove cap. Place pen firmly against skin. Push and hold button until the yellow bar stops moving (5-10 seconds). You'll hear two clicks.
- Remove and Dispose: Lift pen slowly. Needle cover locks automatically. Place in a sharps container immediately.
Conclusion
Choosing where to inject Wegovy from the abdomen, upper thigh, or upper arm depends on personal preference for accessibility and comfort, as all sites provide equally effective absorption. Regular site rotation each week is crucial to prevent skin issues and complications. Always avoid injecting into compromised skin. Following the correct steps for preparation, injection, and disposal ensures a safe and effective experience. Consult your healthcare provider for concerns.
