### output:

Hi, I can understand your concern for itching on body while suffering from diarrhea. It is difficult to make an exact diagnosis of your condition with your current history. For what exact condition you were prescribed loratadine and in what exact dose you are taking it. In general loratadine is a very safe tablet. If I were your dermatologist then would have you to increase the dose of loratadine. It can be increased from 1 tablet to 2 tablets and up to 4 tablets if the itching is not controlled. The only precaution you must follow is not to touch, pinch pop or squeeze any of them otherwise it can get infected and can cause complications. Take care.
