I took Effexor many years ago. We kept increasing the doasge after it was losing it effectiveness. Did finally make me suicidal. My new
Mental nurse practitioner suggested the DNA testing. Pristiq was on the list of one of the ones that would be good and Effexor was one of the ones that wasn't even though they are chemically similar. I've been on 50 mgs of the Pristiq for a few months now and have been doing well.
