The cost of diabetes care in the United States continues to rise, with insulin costs growing rapidly. Accessibility and affordability of these life-saving medications are concerns for providers and patients that need to be addressed. Availability of biosimilar insulin products may help address these issues by introducing additional competition to the insulin market, but they may also face adoption challenges from patients and health care providers alike. In addition, policymakers at state and federal levels are examining and addressing rising insulin costs through legislative and administrative actions. The purpose of this paper is to review the current US diabetes landscape, highlight the differences between biosimilar insulins and follow-on insulins and considerations for successful adoption of biosimilar insulins, and review the current policy landscape regarding rising insulin costs.
