I have not been on this board in forever but my daughter is using Novolog insulin via an Animas pump. I am prescribed 3 vials a month and it usually have to have it filled about every month and a half. At her last endo visit they rewrote her prescription to 2 vials a month. she averages about 60 units a day and is going through puberty and I am constantly adjusting her basal. They refuse to change her insulin prescription back to 3 vials even though she is using more insulin and when she was prescribed 2 vials before we would run out. Sorry this is long, I guess I want to know how many vials other people are using in similar situations.
