How to Use an EpiPen
If you or someone nearby shows signs of anaphylaxis, seek emergency medical care immediately. EpiPens are indicated for the emergency treatment of anaphylaxis and should be administered at the first sign of a severe allergic reaction. Prompt use is critical—delays can be life-threatening.
- Remove the EpiPen from its protective plastic case.
- Hold the EpiPen in your dominant hand near the gray safety release cap—without covering it.
- With your other hand, remove the safety release cap.
- Avoid touching the black tip (this is where the needle exits).
- Aim the black tip toward the outer thigh.
- Swing and firmly press the EpiPen into the thigh at a 90° angle.
- Hold in place for approximately 10 seconds.
- Remove the device and gently massage the injection site for another 10 seconds.
- Look for the red plunger in the viewing window to confirm the dose was delivered.
- Do not attempt to recap the EpiPen. Place the used device in a sharps container or follow local disposal guidelines. If a carrying case is provided, only use it if it safely stores the device post-use.
- Call 9-1-1 or go to the nearest emergency room immediately. The effects of epinephrine may wear off in 15 to 20 minutes.
- Bring the used EpiPen with you for proper disposal and ask for a replacement prescription before leaving the hospital.
