Investigating Real-World Stability and Sterility of in-Use Insulin-An Urgent Public Health Concern. In Sub-Saharan Africa

Insulin stability is a critical yet underexplored factor affecting diabetes outcomes in Sub-Saharan Africa (SSA). High ambient temperatures, unreliable refrigeration, and weak regulatory oversight may compromise insulin quality during storage and use. Patients often rely on traditional, non-validated methods that risk potency loss. This commentary highlights the urgent need for real-world studies on insulin stability and sterility in SSA to inform evidence-based practices and improve glycemic control among diabetic patients in resource-limited settings.
