Though there have been several reports on the usage of epithems and their adverse effects by doctors or pharmacists, very few researchers have conducted surveys on outpatients' awareness concerning these products. In this study, we gave outpatients a questionnaire on their experience of using epithems in order to gauge their awareness regarding them. The survey consisted of two parts, “usage of epithems and their forms”, and “side effects of epithems”. The survey found that the subjects were using epithems once a day and that they desired a small and thin form that did not have a smell. Most of them had experienced side effects due to epithems. However, eighty-five percent of the respondents did not realize that hypersensitivity to light was a severe side effect. The findings of the present study will prove useful in preventing side effects as well as in the development of improved forms of epithems.
