@mmwagner46 When I first started on Alendronate (Fosamax in the U.S.) I had insurance through my employer (Blue Cross/Blue Shield) and so I paid $10 co-pay for a 3 month supply. All of my prescriptions when I was working were the same co-pay because the cost was negotiated through my union contract.

After I retired I went on Medicare Traditional. My Medicare Drug Prescription Plan paid for the prescription and I did not have a co-pay. So my cost was -0-. I will add that Alendronate has been the only medication I was prescribed on Medicare that I did have a co-pay.
