<![CDATA[Cough self-medication is a self-treatment effort widely practiced by the public using over-the-counter (OTC) and limited over-the-counter (limited OTC) drugs. The high prevalence of self-medication practices requires good knowledge to ensure that drug usage is carried out appropriately, safely, and rationally. This research objective is to determine the correlation between knowledge levels and the usage behavior of over-the-counter and limited over-the-counter drugs for cough self-medication in the community of Sidodadi Pardasuka Village. This research is a descriptive-analytic study utilizing a cross-sectional approach. The study population consisted of 3,443 people, with a sample size of 98 respondents selected using a purposive sampling technique. Data collection was conducted using a questionnaire that had been tested for validity and reliability, and then analyzed univariately and bivariately using the Spearman's Rank correlation test. The results showed that most respondents had a good level of knowledge and good drug usage behavior. Bivariate analysis showed a correlation coefficient value of 0.597, indicating a moderate positive relationship between knowledge levels and the usage behavior of over-the-counter and limited over-the-counter drugs for cough self-medication, with a p-value < 0.001, meaning the correlation is significant. In conclusion, there is a positive and significant correlation between knowledge levels and the usage behavior of over-the-counter and limited over-the-counter drugs for cough self-medication in the community of Sidodadi Pardasuka Village. The better the community's level of knowledge, the better their drug usage behavior in cough self-medication.]]>
