I had a similar experience. My med was always brand name (no generics) Then Ins. company decided to change the way they filled it. WITHOUT NOTIFYING ME. The prescription has to be written as
"Capsules" and the generic can be used. Well, the script was being filled and they told me $600. No way.....Took me weeks to get it straightened out with dr to write "as capsules, Generic".....They only come in capsules whether generic or brand....DUH!
Since it was always generic, why didn't they just fill it that way....I was told no generic available....What....did the ins. company change the way they can fill and Boom....a generic was made that day!
