Women’s attempts to achieve their desired levels of fertility are hindered when they stop using contraceptives, which could lead to unwanted pregnancies. This study aimed to assess reasons for contraceptive discontinuation among women of reproductive age in urban and rural areas of Kano State, Nigeria. Qualitative data were collected in urban and rural communities of Kano State in February to May, 2022 from women of reproductive age group, their male partners, family planning service providers, and community and religious leaders. Focus group discussions (FGD), and key informant interviews (KII), using multi-stage sampling methods explored previous experience with contraceptive use, fertility consequences and reasons for contraceptive discontinuation. Following data collection, digitally recorded data were transcribed verbatim, translated, and coded using thematic analysis through an inductive approach. Study reported the high discontinuation rates and identified side effects as the primary reason for discontinuation, with injectable contraceptives being the most commonly discontinued method. Other reported reasons for contraceptive discontinuation by respondents in both urban and rural groups were: method failure, intention to get pregnant, health concerns, husband disapproval, methods not available, inconvenience to use and interference with body structure or functions. The high contraceptive discontinuation poses significant risks of unintended pregnancies and unsafe abortions, thereby increasing maternal morbidity and mortality rates in Kano State. These consequences emphasize the need for family planning interventions that incorporate quality of care in service provision to address contraceptive discontinuation. Engaging men and other social influencers in family planning programs and services will help gather support for contraception, rather than focusing exclusively on women.
