How long does it take for hives to appear after an allergen contact?
A doctor has provided 1 answer
Within minutes : With contact hives, such as after a dog lick, they appear with minutes. After eating food to which you are allergic your lips and mouth become itchy almost immediately and the hives will usually appear within minutes and over 90% of the time within 30 minutes.
