Thanks for your query
I think your sister has some allergic manifestation to the drugs precribed by her doctors. Better to stop those drugs at once if possible. Your sister should have some anti-histaminics like cetrizine
, desloratadine etc. You should consult an allergist. Skin allergy
testing or specific serum IgE assay can detect the culprit allergen and immunotherapy
will protect her from further exposure.
