Introduction

  • Before commencing the challenge, your child should be well. This means their eczema, asthma or hay fever is well controlled, the do not have a cough, cold, diarrhoea or vomiting. If they have started a new medication, wait for two weeks to ensure they tolerate it before introducing wheat. 
  • Do not give your child any antihistamines before or during the challenge days unless a reaction occurs, as these may hide or delay reactions. If your child has used their reliever inhaler such as salbutamol or terbutaline in the last 3 days, delay the introduction. Continue to give your child any other medication that they usually take
  • Do not to introduce any other new foods while introducing wheat into the diet
  • Introduce one of the foods as outlined in table opposite. Try to give the recommended challenge food in one go rather than spreading it out over the day

Keep the tolerated stages in the diet and give regularly.
