Yes, this is the only anticonvulsant that I am taking.  I realized
that it would not be the only factor in my bone loss.  I am a 59 year
old woman - obviously a factor right there.  However from what I've
read a 6% loss in less than two years is quite a lot and I was trying
to figure out why if possible.  It especially worried me because I'd
been taking Premarin for 9 years, although for the last two years the
dosage was at .375 mg.  If the Premarin has helped prevent some bone
loss then I can't imagine where I would have been had I not been
taking it.  I stopped the Premarin last month when I started the
Fosamax.  Now I have the joy of night sweats, but that's another
story...........

I also take Tramadol, 50 mg twice a day for chronic severe back pain,
Vioxx and Prevacid.  The Prevacid gives me frequent migraines for
which I take Midrin about twice a week.  I take a tspn of milk of
magnesia daily and 1000 mg of calcium with vitamin D in divided doses.
I imagine none of this stuff, other than the calcium, can be helping
my bones.  I have not found any link between these drugs and bone loss
on the web but if you are aware of any I'd appreciate the information.

Because of the back problem I am unable to do strength training.  I
walk about 1 1/2 miles a day at about 2.5 miles an hour (pretty slow)
and swim 3/4 of a mile daily.
