6 doctors agreed: Not very long: With food allergies hives either alone or as the first symptom of a more serious life-endangering condition called anaphylaxis typically appear within 5 minutes to 2 hours after the first bite. When appearing in a few minutes hives usually appear around the lips, eyes, face & neck.
