Patient's Query

Hi doctor,

I have allergies on my skin (hives). My skin is bumpy, red and itchy. It is present all over the body. I got these allergies suddenly. I do not remember the cause. I applied a topical analgesic containing Benzyl alcohol with Pramoxine hydrochloride and taken Claritin for allergies.

Please suggest.

Thank you.

Please help.

Thank you.

Hi,

Welcome back to icliniq.com.

I read and understand your concern.

I have gone through the attachment (attachment removed to protect patient identity). You have acute urticaria and take a short course of steroid like Prednisolone 20 mg once daily for seven days and antihistamine like Levocetirizine and Montelukast combination tablet twice daily for 15 days. In most cases, the disease does not go beyond 15 days.

Looking forward to your response in order to help you.

Thank you.
