Replying to
By the way, all four antihistamines seem to affect periods, PMS, and cycles, moods, hormones, and so on.
That is, if my experience suggests anything at all about it.
There are women who say that Zyrtec ( cetirizine ) made their PMS/PMDD better but I suspect that it may even make things worse for some women as well.
YMMV I guess.
