Hello, I am a 68 year old with Type II diabetes for about 7 or 8 years. I started taking a time-release Metaformin. I was taken off of it about 1 year ago due to reduced kidney filtration rate. I have been taking Glipizide ER (10mg). At my appointment yesterday the doctor has now added Januvia (50mg) as my A1C was 8.5. Six months ago it was 6.5.
