Recommended Injection Sites for Wegovy
Wegovy (semaglutide) is injected subcutaneously once weekly using a prefilled pen. The official prescribing information lists the abdomen (at least 2 inches from the navel), front of the upper thigh, or back of the upper arm as approved sites.[1] Rotate sites weekly to avoid irritation.
Why These Sites Work Best
These areas have ample subcutaneous fat for even absorption and minimal pain. The abdomen often provides the most consistent results due to its vascularity, but individual preference matters—thighs suit those avoiding stomach injections, while arms require assistance.[1][2]
How to Choose and Inject Properly
Pick a site with a skin pinch of at least 1/2 inch of fat. Clean with alcohol, insert the needle at 90 degrees, and hold for 5 seconds post-injection. Avoid muscles, veins, or scars. Upper arm injections need a caregiver.[1]
What Happens with Wrong Sites?
Injecting into muscle (intramuscular) risks faster absorption, inconsistent dosing, or pain. Sites like buttocks or lower abdomen near navel increase irritation or poor uptake. Lipohypertrophy from repeated use in one spot reduces effectiveness—always rotate.[2][3]
Patient Tips for Comfort and Side Effects
Ice the area beforehand to numb it. Many report thighs as least painful for self-injection. Bruising or redness is common but fades; lumps signal overuse of one site. Consult a doctor for persistent issues.[3]
Alternatives if Sites Irritate
No other drugs change sites, but if Wegovy bothers, discuss switching to similar GLP-1s like Ozempic (same sites) or oral options. No patents block site guidance—Wegovy's exclusivity runs through 2031 in some markets.1
