Four days ago I started taking 5 mg of Paroxetine for my hot flashes. A little background on my situation: I am taking only 5 mg, because before I started Paroxetine, I tried Brisdelle 7.5 mg for a few days, and experienced unwanted side affects, so I stopped it after about three days. My doc switched me to Paroxetine, and told me to split the 10 mg tablet and try 5 mg nightly. The side affects aren't too bad, but I am not noticing a reduction in the hot flashes, yet. I am wondering how long it will take before I see any noticeable reduction in my hot flashes?
