When should I use my epinephrine injector?

If you think you’re having an anaphylactic reaction, don’t wait to use your injector. And don’t take an antihistamine instead to see if that helps. Use your injector immediately. Your life depends on taking quick action. You also need to call 911 or get to a hospital. Even after you inject yourself, you need medical evaluation and treatment.

If you’re not sure you’re having an anaphylactic reaction, it’s better to inject yourself. The risk of an unnecessary injection is less than the risk of not getting the medicine in time.

If you inject yourself without needing to, you may increase your blood pressure and heartbeat for a few hours. Call your provider or get medical help if that happens.
