Basaglar (insulin glargine injection) is a long-acting, man-made form of insulin that helps lower and maintain blood glucose levels. It works by replacing or supplementing the body’s natural insulin, providing a steady level of insulin activity for up to 24 hours with once-daily dosing. Basaglar is used in the treatment of both type 1 diabetes (in adults and children) and type 2 diabetes (in adults) to help reduce the risk of hyperglycemia and related complications. It is typically used alongside diet, exercise, and sometimes other diabetes medications. Basaglar is supplied in prefilled pens for subcutaneous injection and is designed to provide a consistent, long-lasting effect without the need for mixing or multiple daily injections of basal insulin.
