There are many reasons generics, especially in the case of Medicare patients with chronic conditions, are worse for a patient.
Generally if you have a Medicare patientwith chronic conditions such as diabeties and/or high blood pressure, and their physician has successfully been managing their conditions using a name brand therapy, it’s not good practice to switch their therapy to a generic because it helps the insurance company. More importantly, it’s only the active ingredients in name brand drugs and generics that are the same. coloring agents, binders, etc... are different and those can have significant negative side effects. There is no shortage of examples of generics having worse outcomes in the case of chronic conditions.
Also it’s not just the therapy the insurance is changing, they also change the quantity. So again say you are a Medicare patient with type 2 diabetes and your doc prescribed 30 day Rx so you come back for the doc to check your blood work between fills, insurance is demanding the doctor change the Rx from 30 days to 90 days, because they don’t want to pay for the additional doctor appointment/blood work. They are watering down care and interfering with doctor/patient treatments.
