Self-medication is an action taken by individuals, families, or communities to promote and maintain health, as well as to prevent and treat diseases. According to the Central Bureau of Statistics (BPS) in 2023, approximately 79.74% of the Indonesian population engages in self-medication, with the Yogyakarta region reporting 73.30%, a number that has steadily increased over the past three years. Cough is one of the most common and mild complaints in the community, leading people to prefer self-treatment. However, improper self-medication may pose significant health risks due to limited knowledge about medications and their proper use. This study aims to determine the level of knowledge among students at SMK/SMF Indonesia Yogyakarta regarding self-medication for cough. This research used a descriptive observational method. Data were collected through a validated questionnaire filled out by 60 student respondents, consisting of 11 statements covering the definition of cough, types of cough, and its treatment. The results showed that the majority of respondents had a good level of knowledge (91.6%), especially regarding the concept of self-medication and appropriate selection of cough medications. However, misunderstandings were still found, particularly in recognizing the proper definition of cough and the handling of syrup medications that have changed color. These findings indicate the need for continuous education on self-medication, particularly in ensuring safe drug use.
