You do not have allergies.
General rule of thumb - 30 minutes
Anaphylaxis is the only threatening symptom of allergies you have to worry about. It is impossible for Anaphylaxis to develop after 30 minutes. IF you can hold on for 30 minutes and are still breathing and awake and well, you are perfectly healthy and it is physiologically impossible for you to be having an allergic reaction.
Developing allergies [No Worries]
What have you eaten? Is it something you have been eating your whole life? Then it is impossible for you to develop an allergic reaction to it now and you don't have to be stressed for 30 minutes thinking about it.
If it is not something you have eaten before, wait 30 minutes to be safe, 17 if you're in a big rush. Allergies can be genetic. Does anyone in your family have an allergy to the thing you just ate? If not, you aren't having an allergic reaction.
