I got skin allergy since 13 days back. On the first night I got large red patches on my skin with severe itching so I took allegra 120 mg so the rashes subsided but again in the morning it reappeared so I again took allegra 120 mg twice and again rashes disappeared but next day I consulted a dermatologist, he recommended me momenta CZ Once daily and prugo 25 once daily and dermadew aloe lotion. I suggest want to know is the medicine given by him is correct and how long I have to take the medicines. I also want to know the exact diagnosis of my condition.
