Symptoms are usually mild and may respond to antihistamines, but speak to your doctor to make sure this is the right treatment for you.
Symptoms of pollen food syndrome usually include:
- redness, mild swelling or itching of the lips, tongue, inside of the mouth, soft palate and ears
- itching and mild swelling of the throat that doesn’t interfere with your breathing
- occasionally, people might also have symptoms in the oesophagus (food pipe) or stomach, causing abdominal pain, nausea and vomiting
- sneezing, runny nose, or symptoms affecting the eyes.
Rarely, more serious symptoms can occur, known as anaphylaxis (pronounced anna-fill-axis).
For people with pollen food syndrome, serious symptoms are unusual because the proteins that cause the allergy are unstable and are destroyed with heat or once they reach the stomach. Most people with pollen food syndrome have allergic reactions if they eat the raw fruit or vegetables, but they are able to eat the cooked fruit or vegetables without any problem.
