There is also a 37.5 mg in the XR, I started with this and I am now on 225mg.
I used the 37.5mg for each increase with my Drs. Blessing.
Effexor XR comes in capsules in 37.5mg, 75mg and 150mg. For my 225mg dose I take 150mg +75mg of the XR.
It is hard to get onto these meds so try to hang in there. The first 4-6 weeks can be a rough ride.
I am right here cheering you on.
