Correct answer: E — It may be used in coeliac disease, but not in wheat allergy

The product leaflet states that its wheat starch contains only very low levels of gluten and is very unlikely to cause problems in coeliac disease. It also states that the product should not be taken by a patient with wheat allergy. Product and manufacturer matter because excipients can differ between formulations.
