Hi welcome to Health care magic forum.
Thanks for sending a question to H.C.M.Forum.
Your son aged 8 years has allergy
to nuts and cat. you are lucky that you find the allergen the causative factor.
comes when ever he comes in contact with the allergen. As he is allergic to limited number of things, there is possibility of complete cure from the allergy by using a combination of montelecast and levocitrizine under the supervision of a pediatric specialist.
Wishing him a quick and complete recovery.
