I mailed Rx's to Walgreens and they filled most of them with generics which is what they are supposed to do. The Rx that they messed up was for Colchicine. Of course the doctor authorized a substitute which actually means that they could fill Rx with a generic. This is supposed to cost me $15.00 for 3 months. But they sent me Colcrys which is the brand name and a charge of $102. Walgreens didn't bother to notify me of their substitution, which I would have refused, and sent the Colcrys to me without my ok. I have tried to return the Rx but they will not allow that. I have talked to and emailed several people and no one gives any useful info. Nor do any of them seem to know what they are doing.
