Egg allergy reactions vary from person to person and usually occur soon after exposure to egg. Egg allergy symptoms can include:
- Skin inflammation or hives â the most common egg allergy reaction
- Nasal congestion, runny nose and sneezing (allergic rhinitis)
- Digestive symptoms, such as cramps, nausea and vomiting
- Asthma signs and symptoms such as coughing, wheezing, chest tightness or shortness of breath
A severe allergic reaction can lead to anaphylaxis, a life-threatening emergency that requires an immediate epinephrine (adrenaline) shot and a trip to the emergency room. Anaphylaxis signs and symptoms include:
- Constriction of airways, including a swollen throat or a lump in your throat that makes it difficult to breathe
- Abdominal pain and cramping
- Rapid pulse
- Shock, with a severe drop in blood pressure felt as dizziness, lightheadedness or loss of consciousness
Discuss with your doctor any reaction â no matter how mild â you or your child has to eggs. The severity of egg allergy reactions can vary each time one occurs, so even if a past reaction was mild, the next one could be more serious.
If your doctor thinks you or your child may be at risk of a severe reaction, he or she may prescribe an emergency epinephrine shot to be used if anaphylaxis occurs. The shot comes in a device that makes it easy to deliver, called an autoinjector.
When to see a doctor
See a doctor if you or your child has signs or symptoms of a food allergy shortly after eating eggs or an egg-containing product. If possible, see the doctor when the allergic reaction is occurring. This may help in making a diagnosis.
If you or your child has signs and symptoms of anaphylaxis, seek immediate emergency treatment and use an autoinjector if one has been prescribed.
