Where and How to Inject Wegovy

Key takeaways

• Wegovy (semaglutide) is injected under the skin of the lower abdomen, upper arm, or upper thigh—rotate your injection site each week. Do not administer Wegovy into a vein or muscle.
• To ensure you receive the full dose, follow the Wegovy pen’s instructions: press the pen firmly against cleansed skin until the yellow bar on the pen stops moving.
• Store Wegovy pens in the refrigerator and shield them from light. If preferred, you may remove Wegovy from the fridge an hour or two before injecting.

Wegovy is a prescription medication prescribed for weight reduction and to lower certain heart-related risks in eligible individuals. It’s also used to treat metabolic dysfunction-associated steatohepatitis in adults with liver fibrosis.

Wegovy is supplied as a clear solution in prefilled, single-dose pens and is administered as a subcutaneous injection.

Where to inject Wegovy

Inject Wegovy into your lower abdomen (at least 2 inches away from your navel), the upper arm, or the front of the upper thigh. No single site is superior—each of these areas is an acceptable location for Wegovy injections.

You may repeatedly use the same general area of the body, but you should change the precise spot. For instance, you might inject the upper left thigh one week and the upper right thigh the next. Alternatively, you can stay on the same thigh but choose a point a few inches from the previous injection.

Avoid injecting into skin that has stretch marks or scars, or into areas that are tender, hardened, bruised, or discolored.

If you’re finding it hard to reach a soft spot, pick a firmer location such as the upper thigh. When injecting into the lower abdomen, standing up can help make the skin firmer and easier to inject.

Before your first self-injection of Wegovy, consult your physician or another healthcare provider. They will teach you how to inject and advise which injection sites are most suitable for you.

How to inject Wegovy

Before each injection, check that the pen is intact, the medication has not expired, and the liquid visible in the pen window is clear and colorless. If anything seems off, contact the manufacturer at 833-WEGOVY-1 (833-934-6891).

To ensure you receive the entire dose, follow the instructions included with your Wegovy pen. The procedure is:

1. Clean the injection site with alcohol or soap and water, then allow it to dry.
2. Remove the cap by pulling it straight off, then press the needle cover firmly against your skin.
3. Hold pressure until the yellow bar stops moving. You will hear two clicks during this process: the first indicates the injection has started, the second indicates it continues.
4. Keep steady pressure until the yellow bar stops moving (roughly 5–10 seconds after the first click).
5. Gently lift the pen away from your skin.
6. If bleeding occurs, apply light pressure with a cotton ball or gauze.

If you remove the pen from your skin too quickly or don’t press it firmly enough throughout the injection, you might not receive the complete dose. You may observe fluid leaking or squirting from the needle or pooling on the skin.

Once an injection is stopped, it cannot be restarted—the needle cover locks as soon as you pull it away from your skin.

Dispose of used Wegovy pens in an FDA-approved sharps container. If you do not have one, use a sturdy, leak-resistant plastic container with a secure lid and clearly label it as hazardous waste. For additional guidance on safe sharps disposal, see this FDA resource.

When to inject Wegovy

Wegovy is administered once weekly. You may inject at any time of day that suits you, regardless of meals. You can change your weekly injection day provided at least 2 days have passed since your previous dose.

How to store Wegovy

Proper storage is essential to preserve Wegovy’s effectiveness:

• Keep Wegovy refrigerated at 36°F to 46°F (2°C to 8°C).
• Do not freeze Wegovy.
• Store the pen in its original container to protect it from light.

Discard a Wegovy pen if it has been:

• frozen
• exposed to temperatures above 86°F (30°C)
• left unrefrigerated for 28 days or longer
• exposed to light

Does the Wegovy injection hurt?

The Wegovy pen uses a very small needle to deliver medication into the subcutaneous fat layer. Because the needle is short and fine, many people hardly feel it.

Some individuals, however, are sensitive to injections of cold liquid. If this concerns you, remove Wegovy from the refrigerator one to two hours before injecting. Keep the pen capped until you’re ready to inject. Allowing the medication to reach near-room temperature can lessen injection discomfort.

If you have questions about side effects or interactions, including queries about sexual side effects sometimes discussed online, you may find information such as ozempic penis glp 1 side effect relevant to related GLP-1 concerns, but always discuss any worries with your healthcare provider.

Summary

Wegovy can be injected into the upper arm, front upper thigh, or abdomen (at least 2 inches from the navel). Hold the pen firmly against your skin until the yellow indicator stops moving to confirm the full dose has been delivered.

For detailed injection guidance, view the instructional video on the manufacturer’s website. The same steps are outlined in the drug’s prescribing information (pages 38–44) and in the Instructions for Use included with Wegovy.

If you have any questions about injecting Wegovy, consult your physician or pharmacist.
