Klaron Professional Information


In controlled clinical trials for the management of acne vulgaris, the occurrence of adverse reactions associated with the use of Klaron Lotion was infrequent and restricted to local events. The total incidence of adverse reactions reported in these studies was less than 2%. Only one of 105 patients treated with Klaron Lotion had adverse reactions of erythema, itching, and edema. It has been reported that sodium sulfacetamide may cause local irritation, stinging, and burning. While the irritation may be transient, occasionally the use of medication has to be discontinued.
