Due to insurance complications, my doc switched me from the generic of effexor to brand name pristiq. Everyone says they are the same medication but I seem to notice huge differences. My was much more managed on effexor the the pristiq. I feel like I've been running 100 miles an hour since starting the new medication and and more unfocused then ever. I'm super irritable with just the small things which is triggering my anxiety. Has anyone ever experienced switching the 2 medications.? I don't understand why if they are the same I feel so differently?
