Anaphylaxis VS Biphasic Anaphylaxis
Biphasic anaphylaxis is anaphylaxis part two. It is a secondary reaction that strikes after you’ve survived the initial attack. It happens with no additional exposure to the allergen. This second attack can occur anywhere from 1 hour to 72 hours after the initial anaphylactic reaction. It commonly happens within 10 hours.
The symptoms of biphasic anaphylaxis are the same as anaphylaxis. They may differ in severity, though, and are typically mild or moderate. Since there’s no guarantee that the second event won’t become a life-threatening one, doctors want you to stay in the hospital after the initial attack to monitor your condition. This is because every episode requires immediate medical attention.
Call 911 immediately if you or someone you’re with is experiencing an anaphylactic reaction. Your goal is to get professional medical care as quickly as possible. Your goal is to get professional medical care as quickly as possible.
If you’re with someone who’s having an attack:
Ask if they have an epinephrine auto-injector.
If they have an auto-injector, inject them yourself if they can’t do it.
Help them get comfortable and elevate their legs, if possible.
If needed, perform CPR.
