Several types of insulin available

Updated On Jan 12, 2022

Insulin therapy is the most common type of medication for type-1 diabetes, but also used in type-2 diabetes treatment. Insulin acts as a replacement for or supplements your body’s insulin.

There are different types of insulin, which vary on how quickly they begin to work and how long they have an effect. It is important to closely monitor your sugar level, when administering insulin therapy.
