A member asked:

Is there a parabolic relationship btw the efficacy of effexor (venlafaxine) and dose? is there a point at which higher doses become not only ineffective but harmful

See answer: With many medications, including Effexor, (venlafaxine) as you increase the dose you reach a point beyond which no additional efficacy is gained by further increase and/or unacceptable side effects occur.
