IshI,
This seems to be something that is prescribed fairly regularly together. They are compatible, yet are of differing structures, so there is no worry of overloading by combination.
I don't remember if we have any members who are currently on this same combination...
...but I did look up some disscussions on other boards, and found this response, and a few similar responses:
For me, Remeron + SSRI has worked when neither one alone worked. It's a good combination, at least for me.
Best wishes with this! Let us know how it goes.
S.C.
