I have type 2 diabetes and have had it for at least 40 years. I am 84 years old and in fairly good health. I take Metformin (2000 mg/day), Pioglitizone (15mg/day), Glimepiride ((5mg/day), Invokana (150 mg/day) My insurance company is dropping Invokana in 2019. They will crary Farxiga and Jardiance. Farxiga will be much cheaper then Jardiance. Can you tell me any advantages or disadvantages of the three.
