Abstract
Self-medication is the selection and use of drugs without medical prescription, to treat diseases or for symptomatic relief. This article is a systematic review on self-medication in skin diseases. A search was conducted on Virtual Health Library and PubMed databases using predetermined descriptors. Two researchers performed the article selection process independently, with the degree of inter-observer agreement measured by the kappa index. The prevalence of self-medication ranged from 6.0 to 45.0%. Topical corticosteroids were the most commonly used therapeutic strategies for self-medication, as found in the reviewed articles. This study revealed that published data on self-medication in dermatology are scarce, although the findings showed that it was a common practice.
