my daughter is 10yrs, she is allergic to insect bits, she has a lot of mosquito bites on her, it becomes blisters and swollen red, the chemist gave me allergex to give her at night, is it risky for a allergic child, would she be too sleepy tomorrow. THe thing is that aspen Ceririzine only work in part the itchiness is still very much there, so the Chemist promised me the allergex will also take the itchiness... what is the best for my child?
