Background: Adherence is a process that patients must follow in completing treatment regimens and complying with recommendations provided by healthcare professionals and family members. Research has shown that non-adherence to hypertension treatment can hinder blood pressure control, thereby requiring interventions to improve adherence. Hypertension is a chronic condition that must be continuously managed to prevent complications that may lead to death. Purpose: This study aimed to describe the level of medication adherence among hypertensive patients during the COVID-19 pandemic at the Sosopan Primary Health Center. Methods: This is a quantitative exploratory study with purposive sampling technique in which samples were selected based on inclusion criteria Results: A total of 93 patients met the criteria. Data were collected using the Morisky Medication Adherence Scale (MMAS-8) questionnaire. The study was conducted from February 10 to April 20, 2022. The collected data were analyzed descriptively using frequency distribution analysis. The results showed that 27 respondents (29.0%) had high adherence, 51 respondents (54.8%) had moderate adherence, and 15 respondents (16.1%) had low adherence. The primary reasons for not taking antihypertensive medication regularly during the pandemic included fear of being swabbed at the public health center (24.8%), feeling healthy (19.3%), and forgetting to take their medication (8.3%). Conclusion and recommendation: These findings indicate that although some patients adhered well to their antihypertensive treatment, a substantial proportion had not yet achieved optimal adherence. Overall, the results highlight the need for targeted interventions to improve medication adherence among hypertensive patients,
