The most prescribed medications in the US for diabetes are metformin, glipizide, actos, januvia, jantumet (januvia and metformin together) The most popular insulin are novolog, novolin, byetta, lantus solostar and humalog. Most of them come in pens or 10 ml vials. I dunno what these medications are called in the indian pharmaceutical market. I wish I could give you suggestion on the insurance but unfortunately I don t know any.
