Dotty, as far as I known there's no such thing as a 'generic brand' drug, it's either generic or branded. Gepretix has different fillers, grape seed oil is one of them, so it's not exactly the same as Utrogestan, although the active ingredient is micronised progesterone. Also, a generic drug has no brand name, in this case it would be called 'Micronised Progesterone Capsule' or something like that, same as Estriol Cream and not Ovestin, for example.
