I was on Effexor XR 112 for 6 months, when I got back my anxiety symptoms. The Dr. upped it to 225 mgs, but my BP rose unbelievably, so I was (cross tapered gradually) and put on Prozac from 10 to 20 mgs. I have been on 20 mgs now for 4 weeks and I still feel horrible. Do you think an increase will help in Prozac? Any suggestions.
