Common symptoms Symptoms may include hives, swelling, vomiting, abdominal pain, cough, wheeze, throat tightness, dizziness or collapse. Reactions often begin soon after eating.
Diagnosis Diagnosis combines a detailed history with skin-prick or blood testing when appropriate. Positive tests alone do not always prove clinical allergy. A medically supervised oral food challenge may be needed.
Emergency treatment Anaphylaxis requires immediate intramuscular epinephrine and emergency help. Antihistamines do not replace epinephrine for breathing or circulatory symptoms.
Prevention and daily management Families should read labels, inform schools and caregivers, carry prescribed medication and follow a written allergy action plan. Unnecessary food avoidance can harm nutrition.
Seek specialist advice before reintroducing a suspected food or excluding major food groups.
