How is Wegovy used?
Wegovy should be used as prescribed by your doctor by injecting the medication under the skin (subcutaneously).
Follow the patient information that comes with your medication. Wegovy comes as a one-time use injection pen to be injected under the skin of your stomach (2 inches away from your belly button), thigh, or upper arm.
Wegovy can be injected with or without food.
- Before injecting Wegovy, you will need an alcohol swab, gauze pad or cotton ball, and a sharps disposable container. Make sure to wash your hands thoroughly before preparing the selected injection location.
- Select your injection site and clean with an alcohol swab. The injection site should be rotated so as not to be in the exact same location as the last injection.
- Do not inject in areas with scars, stretch marks, bruises, or where the skin is tender, hard, or red.
- Do not use the injection pen if it appears to be broken or has been used or if it has expired.
- Remove the pen cap and inject Wegovy firmly into the selected site. Push until the yellow bar stops moving, and you hear two clicks.
- First click signals the injection has started.
- Second click signals injection is ongoing.
- After the injection, dispose of the injection pen in the sharps disposable container. Do not throw the injection pen in the trash. If you do not have a sharps disposable container, contact your doctor or pharmacist for alternatives.
- If there is blood on the skin after the injection, use the gauze pad or cotton ball to press and clean the injection site.
Wegovy is prescribed to be administered on a titration schedule where the dose is gradually increased every month until the full dose of 2.4 mg is reached. Each dose or strength comes in a different color so that you can easily identify what strength you are using.
Wegovy should be injected on the same day of the week as the last dose following the titration schedule:
- In the first month: inject 0.25 mg of Wegovy 1 time per week exactly 7 days apart.
- In the second month: inject 0.50 mg of Wegovy 1 time per week exactly 7 days apart.
- In the third month: inject 1 mg of Wegovy 1 time per week exactly 7 days apart.
- In the fourth month: inject 1.7 mg of Wegovy 1 time per week exactly 7 days apart.
- In the fifth month: inject 2.4 mg of Wegovy 1 time per week exactly 7 days apart.
Wegovy injection pens should be stored in the original box in the refrigerator until ready to be used.
