I suffer from OCD, I stay in China. I am a Neuroscientist. From last one year I was on Fluvoxamine. I started with 200 mg and my intrusive thoughts are checked. Then after 4 months I reduced to 150 mg, and this was also effective, again I reduced to 100 mg, and my symptoms were in check. Recently week back the dossage I reduced to 50 mg, but ocd retuns full fledged, So I am now with 100 mg for last 4 days, but symptoms are stll same. Could you suggest what exact dossage I need to check?
