not INSTEAD but prami s used if ur prolactin levels are high....some ppl just dont tolerate it well -like me-and feel like crap on it even at a very small dose....Dostinex is far better - almost no side effects. Bromocriptine is another anti prolactin but it also can make u feel like shit.
so spend a cpl of $$ extra and get dostinex - good stuff. But it snot a replacement of Viagra or Cialis
