General Public Knowledge Regarding Topical Corticosteroids: A Nationwide Survey in South Korea

Abstract

Background: Topical corticosteroids (TCs) are available both as over-the-counter drugs and prescription medicines at pharmacies. Although they are generally safe drugs, inappropriate and excessive use could result in potential side effects. Thus, it is important tohave appropriate knowledge regarding the use of TCs. We performed a cross-sectional survey to assess public knowledge and thepotential misuse or overuse of TCs. Methods: A cross-sectional and nationwide online survey was conducted among participantswho were aware of TCs. The survey items included sources of information, indications, potential side effects, and methods ofapplication of TCs. A comparative analysis was conducted between those with (TC users) and without (TC non-users) an experienceof using TCs. Results: Among 3,000 participants, 74.4% were TC users. The mass media was the most common information sourceof TCs, and only one-third of the surveyed people relied on pharmacists or doctors for information. Regarding indications andapplication methods, incorrect answer rate was high in some items, but respondents showed adequate knowledge. However, awarenessof the safety of TCs was low. Overall, the TC users showed a higher knowledge of TCs than TC non-users. Conclusions: Publicknowledge of the use of TCs appears to be appropriate. However, we found potential misuse or overuse of some items and a lack ofawareness of the side effects concerning TCs. Thus, healthcare professionals’ significant role is required.
