Hi, My mrs.  has been bitten by some insect near elbow. After three day  rashes with itching sensation occurred in whole body then she went to a skin doctor. It was suspected as allergic to insect bite  and was given injection Avil and Dexa, 2cc. The rashes went off in a hours time . But got the same problem in the evening. she is  taking table Allegra 120 mg .Doctor has given this for 3 days. The rashes are still there  as well as avil inj. is totally not effective. Can you advise what is the reason and how much serious this is. There is no change in the food that was taken recently.
Hi, Welcome to Chat Doctor, After going through your history, she had allergic reaction to insect bite that is urticaria hypersensitivity reaction to insect bite. Treatment is antihistamines and corticosteroids for short duration which doctor has given, and please continue treatment as advised by Physician it will take some time to settle down. There are immediate and late phase allergy if symptoms are severe then consult doctor and short term course of corticosteroids may be required, but do so only after consulting Physician. Hope this helps. Take care. Good Luck. Chat Doctor. D.
