Background: Subdermal contraceptive implants are among the most effective long-acting reversible contraceptive methods available. Implanon Nxt is a single-rod etonogestrel-releasing implant that provides reliable contraception for up to three years. Despite its high contraceptive efficacy, users may experience certain side effects, particularly menstrual disturbances, which may influence continuation rates. Objective: To assess the effectiveness and side effects of the subdermal contraceptive implant Implanon Nxt among women attending a tertiary care institute in western Rajasthan. Materials and Methods: This hospital-based prospective observational study was conducted at Umaid Hospital, Dr. S.N. Medical College, and Jodhpur from January 2025 to December 2025. A total of 368 women of reproductive age who opted for Implanon Nxt insertion were included in the study. Baseline sociodemographic and clinical data were recorded using a pre-designed proforma. Participants were followed to evaluate the effectiveness of the implant and to document any side effects experienced during the study period. Data were analyzed using descriptive statistics and presented as frequencies and percentages. Results: The majority of participants belonged to the 20–24 years age group (37.8%). Most women were urban residents (76.5%) and housewives (91.2%). Multiparous women constituted 64.2% of the study population. Side effects were reported in 65.7% of participants, with menstrual disturbances being the most common (54.9%), followed by non-menstrual side effects (18.1%). Implant removal was observed in 2.2% of cases, with side effects being the most frequent reason for discontinuation (72.7%). Conclusion: Implanon Nxt was found to be a highly effective and safe long-acting reversible contraceptive method. Although menstrual disturbances were commonly reported, the overall discontinuation rate was low.
