My husband is 70 years old and is on medicare. He has a supplemental Part D drug Plan and between these 2 insurance plans, neither will cover bystolic. I do not understand how they can do this, since there is no generic available. I believe that our income is too high for any assistance. He also takes prescription drugs for diabetes, gout and heart bypass. What can I do to avoid having to pay 100% of the cost of bystolic?
