I saw a dose response curve for Effexor on the internet...which does not mean it is true..but assuming it was true:Effexor acts as an SSRi..that is a Prozac, Paxil, Lexapro etc like med at a very low dose 37.5 mg was about
as good as 75 mg..where the curve flattened out
The response stayed flat until about 150mg where it started to work on norepinephrine Did not affect the reuptake of Dopamine til about 300mg daily
