4. What should I do if my child experiences side-effects whilst participating in the study?
Most children will not have any side-effects from the antibiotic. However, up to 1 in 10 might get minor side-effects such as a slight stomach or thrush. Unexpected serious allergic reactions can very rarely occur with symptoms such as lip swelling, throat tightness and difficulty breathing. If this happens, please seek medical advice immediately, or go to hospital or call for an ambulance if your child is very unwell.
