i am taking this med and my prior rx was manufactured by rivers edge-it work great. since then my pharmacy switched brands and supplies me with breckenridge, the pill is not nearly as effective. i switched pharmacies and they supplied me a product from excellium- it looks identical to the breckinridge pill with the exception of the numbers. the pharmacist said i can return the full count back to them, if i use any they will not allow me to return it.i have not been able to find out if its manufactured by the same company and distrubuted by the two.any help on this?thanks
