Side effects are common, especially in older children, but are usually mild. The most common side effects are stomach pain/cramping and itching of the mouth or throat. These symptoms are usually mild and typically do not require intervention. Antihistamines, or reducing the dose can be helpful if these are problematic. It is important to be aware that food allergens can cause severe life-threatening reactions, known as anaphylaxis, in the same way that the food in other forms can do. Symptoms include but are not limited to: trouble breathing, wheezing, chest tightness, throat tightness, trouble swallowing, swelling of lips, face, tongue or eyes, dizziness, fainting, severe stomach pain, vomiting, and/or diarrhoea. If you experience any of these symptoms, stop and seek medical attention immediately. You will be trained in recognising and treating severe reactions at the start of treatment.
