Product Details


Basaglar is a medication and long-acting insulin that can be used for either Type 1 or Type 2 diabetes treatment and specifically with regulating blood sugar levels. With Type 2 diabetes treatment this insulin injection works to promote more sugar moving into cells and not remaining in the blood, while with Type 1 diabetes treatment it makes up for the body’s natural lack of insulin. It is typically used in combination with a mealtime insulin medication to get A1C hemoglobin test scores down to 7% of lower as a measure of effective blood sugar control. Basaglar insulin may also be prescribed for children ages 6 and up with Type 1 diabetes.
