Glargine is primarily used for managing type 1 and type 2 diabetes in adults and type 1 diabetes in children and belongs to the class of long-acting synthetic insulin analogues.
Besides controlling blood sugar levels in patients with type 1 and type 2 diabetes, it also helps manage diabetes symptoms like increased thirst, frequent urination, unexplained weight loss, fatigue, irritability, blurred vision, slow-healing sores, frequent infections, and increased ketone levels in urine.

Glargine is a synthetic long-acting insulin.
It functions by acting like naturally occurring insulin in your body. Insulin is a hormone that regulates sugar levels in your blood.
It performs three key actions to manage blood sugar levels:
It stimulates the uptake of glucose in cells of skeletal muscles and adipose (fat) tissue, thus reducing the amount of glucose in your blood.
It inhibits the production of glucose in the liver, further reducing the amount of glucose available in your blood.
It reduces glucose reabsorption in the kidneys, ensuring that excess glucose is eliminated from your body through urine.
Through these actions, Glargine maintains proper glucose balance in your body and helps manage diabetes effectively.
