Dysmenorrhea is one of the most common complaints experienced by adolescent girls during menstruation and may interfere with their daily activities. Various non-pharmacological approaches have been used to help reduce menstrual pain, including pineapple juice and green coconut water. This study aimed to describe changes in menstrual pain intensity following the administration of pineapple juice and green coconut water among adolescent girls with dysmenorrhea at the Faculty of Health Sciences, Dirgantara Marsekal Suryadarma University, in 2026. This study employed a descriptive case study design involving four participants with dysmenorrhea. Pain intensity was measured using the Numeric Rating Scale (NRS) before and after the intervention. Two participants received pineapple juice, while the other two received 250 mL of green coconut water twice daily for three consecutive days during menstruation. The observational findings showed that all participants experienced a reduction in pain intensity during the three-day observation period. Among participants who received pineapple juice, pain scores changed from 6 to 2 and from 5 to 1. Among participants who received green coconut water, pain scores changed from 6 to 3 and from 5 to 1. These findings describe the changes in pain intensity observed in each participant during the observation period. Because this study used a case series design with a limited number of participants, the findings should not be interpreted as evidence of comparative effectiveness or causality.
