In my experience with Effexor, I had to taper over a period of about 6 months because I was having a lot of dizziness while I was coming off of the medication. My doctor was very good about
tapering me off very slowly. (By the way, I was on
Effexor for about a year and a 1/2 and my peak dose was 150 mg).
When I was tapering and got down to the 75 mg range of dose, I dropped it to 37.5 mg for several weeks. Then I took 1/2 of the 37.5 mg capsule to make it roughly 16 mg.
