What is an economical treatment for diabetes?

Q: My age is 32 and I am suffering from diabetes for the last 5 years. My father was also suffering from diabetes. I am from the middle class. I am an insulin dependent patient. I use Penfill now but it is costly so please give me some information about cheap way to get insulin. As I know, some company give insulin bulb in Rs. 145, what is it?

A:To save costs, you can use syringes and vials instead of penfill. Also you could use monocomponent animal insulin instead of human. Monocomponent animal insulin is made by USV.
