I just filled a script for phentermine 37.5 @ a costco pharmacy. I was asked if I wanted a generic, I said yes! To begin with, I thought "phentermine" was a generic for a few other brand name drugs. But what I bought isn't exactly the same as my last script; (phentermine cac vs. phen. kvk, by looks and formulation.) I haven't taken it yet but i'm concerned that it will not have the effectivness I need. Is this: "a generic for a generic," or what...?

Get it at Target. It is $32, but it really works. This pill from Costco was extremely ineffective, compared to the one I got for 2 years at Target.

Bonnie, the doctor told me that if you were to buy the generic kind the effectiveness of the pill is a lot less. with that specific kind you would need to take it 3 times a day.

All good quality generics have the same efficiency as branded drugs. for example even indian generics have high consumers popularity online because of rather low cost and acceptable quality.
