Wegovy is the first and only prescription weight-management medicine taken once weekly. It’s taken on the same day each week, any time of day, with or without food.

Wegovy is available in 5 different dose strengths, ranging from 0.25 mg to 2.4 mg. Each dose comes in a different colour pen. Your healthcare provider will increase your dose over time until you reach your maintenance dose.

Preparing for your injection

Supplies you will need to give your Wegovy injection:

  • your Wegovy pen,
  • 1 alcohol swab or soap and water,
  • 1 gauze pad or cotton ball,
  • 1 sharps disposable container for used Wegovy pens

STEP 1: Wash your hands.

STEP 2: Check your Wegovy pen

  • Do not use your Wegovy pen if:
    • The pen appears to have been used, or any part of the pen appears broken; for example, if it has been dropped
    • The Wegovy® medicine is not clear and colo<sup>u</sup>rless through the pen window
    • The expiration date (EXP) has passed

STEP 3: Choosing your injection site

  • Your healthcare provider can help you choose the injection site that is best for you.
  • You may inject into your upper legs (front of the thighs), lower stomach (keep 2 inches away from your belly button), or upper arm.
  • Do not inject into an area where the skin is tender, bruised, red, or hard. Avoid injecting into areas with scars or stretch marks.
  • You may inject in the same body area each week, but make sure it is not in the same spot each time

Clean the injection site with an alcohol swab or soap and water. Do not touch the injection site after cleaning.

Injecting Wegovy

STEP 1: Pull the pen cap straight off your pen.

STEP 2: Push the pen firmly against your skin and keep applying pressure until the yellow bar has stopped moving

  • If the yellow bar does not start moving, press the pen more firmly against your skin.

  • You will hear 2 clicks during the injection

    • Click 1: The injection has started
    • Click 2: The injection is ongoing

Troubleshooting

If you have problems injecting, change to a more firm injection site, such as upper leg, or upper arm or consider standing up while injecting into the lower stomach

If medicine appears on the skin or squirts from the needle, make sure the next time you inject to keep applying pressure until the yellow bar has stopped moving. Then, you can lift the pen slowly from your skin.

What if blood appears after injection?

If blood appears at the injection site, press lightly with a gauze pad or cotton ball.

Safe storage and disposal of your Wegovy Pen

Protecting your pen

  • Do not drop your pen or knock it against hard surfaces
  • Do not expose your pen to any liquids
  • If you think that your pen may be damaged, do not try to fix it. Use a new one
  • Keep the pen cap on until you are ready to inject. Your pen will no longer be sterile if you store it without the cap, if you pull the pen cap off and put it on again, or if the pen cap is missing. This could lead to an infection

Storing your pen

  • Store the Wegovy pen in the refrigerator from 2°C to 8°C (36°F to 46°F).
  • If needed, before removing the pen cap, Wegovy can be stored from 8°C to 30°C (46°F to 86°F) in the original carton for up to 28 days
  • Keep Wegovy® in the original carton to protect it from light
  • Do not freeze: Throw away your pen if Wegovy® has been frozen, exposed to light or temperatures above 86°F (30°C), or out of the refrigerator for 28 days or longer.

Safe disposal of your Wegovy Pen

  • Safely dispose of your Wegovy pen immediately after completing your four weekly doses.
  • Do not throw the pen away in your household waste.
  • Instead, you should use a sharp safe disposal container.
  • This can be a sturdy household container with a tight-fitting lid, like a heavy-duty plastic container.
  • Learn more in the Wegovy Medication Guide.
