 How long does it take for an allergic reaction like hives to show up after eating something?

Also, how soon after stopping eating the food does it go away?

Depends on how bad the it is. Some react within seconds some take a few hours.

In most cases it only takes a short time like minutes.I have some food allergies and hives show up within a few minutes of digestion.

A food allergy can occur within minutes and up to an hour or so depending on the severity of the allergy and the amount ingested. If you know that you have food allergies then you should have her doctor prescribe you an epi-pen that can administered with the first onset of the reaction. The doctor can also prescribe antihistimines, but for fast relief they can prescribe prednisone which realive the symptoms quicker. in a severe reaction most patients are given an injection of epinephrine to counteract the allergic reaction and symptoms.

The onset of allergic reaction is immediate..probably within 1 minute,sometimes upto 5 to 10 minutes,or even longer.It'll take rather long to disappear after stop eating the food which trigger the allergic rash.unless you take anti histamine tablets,it'll take quite long to resolve
