I too was concerned about changing when nothing was wrong except price
. Effexor XR was going to cost me cash price
for 120 caps of 75mg--$550.00+. Couldn't do. The Pristiq he said was A purifies form of Effexor with the side effects (bad) removed. My only problem is a slight headache, but that could be fron number of things. It is only $132.00. He gives samples. I have been able to go to a site at ppaRx.com, I believe, someone help me here.
