Hi there, Thank you for posting your question. I will do my best to help you Rash around the anus could be due to reasons like Nappy rash, sweat around the anus,stools debris around the anus, worm infestation and fungal Infection . This is quite common in children. Allergies usualy affetc the eyes skin,eyes,neck and can also cause sneezing (respiratory allergies) Anyways continue to apply the cream prescribed as mentioned -rash usual subside within a few days .Nothing to worry.Be assured. Consult your paediatrician and take advice on with worm infestation (single dose is given usualy) Try Candid B cream for the rash and keep the anus area clean and dry before applying the cream. Change undergarment to keep the area dry.If the child is at home, avoid panty for a week to heal faster. Daytime also apply cotrimazole dusting powder(ABZORB Powder) if the child need to go out. If still persists, please consult a dermatologist for further evaluation I hope that I have answered your questions fully and been of some help. If you have anymore questions please contact me again anytime Regards, Dr.Sushma
