Approved Semaglutide Injection Sites
Semaglutide is injected subcutaneously (under the skin) into fatty tissue. The FDA approves three areas for injection:
1. Abdomen (Stomach Area)
The most popular injection site. Use the area at least 2 inches away from your belly button. The abdomen typically has more subcutaneous fat, making injections easier and often less painful.
Recommended for: Most users, especially beginners
2. Thigh (Upper Front)
The front and outer side of your upper thighs are good alternatives. Focus on the middle third of your thigh, avoiding areas close to the knee or groin.
Recommended for: Those who prefer thigh injections or have limited abdominal fat
3. Upper Arm (Back)
The fatty area on the back of your upper arm works well but typically requires assistance from another person to inject properly.
Recommended for: When someone else administers the injection
Step-by-Step Injection Guide
- 1
Prepare Your Materials
Gather your semaglutide pen, a new needle, and alcohol swab. Let the pen warm to room temperature if refrigerated.
- 2
Clean the Injection Site
Wipe the area with an alcohol swab and let it dry completely before injecting.
- 3
Pinch the Skin
Gently pinch a fold of skin between your thumb and fingers to lift the fatty tissue away from the muscle.
- 4
Insert the Needle
Insert the needle at a 90-degree angle (straight in) into the pinched skin.
- 5
Inject and Wait
Press the button and hold for 5-10 seconds after the dose counter shows 0 to ensure full delivery.
Why Rotation Matters
Rotating your injection sites is crucial to prevent lipodystrophy—a condition where fatty tissue under the skin changes, becoming either lumpy (lipohypertrophy) or indented (lipoatrophy). This can affect how the medication is absorbed.
Sample 4-Week Rotation:
- • Week 1: Right side of abdomen
- • Week 2: Left side of abdomen
- • Week 3: Right thigh
- • Week 4: Left thigh
Within each area, use a slightly different spot each time.
