Skin Rashes

Patient: My doctor had advised Montek LC Kid and Flomist nasal spray for my 5 yr old daughter after she underwent surgery about 5 months ago for adenoidectomy and grommet insertion in the ears. After taking the drug for roughly 30 days she has developed severe rash over her legs till waist and over her arms with swelling or inflammation and pain. Can this be regarded as a side effect of Montek LC Kid. What are the options available now.
