Thanks for the many replies and well wishes.  It seems that many people
have experienced this problem.

Many said that generic brands are more prone to recall.  References
pertaining to the recall of Levoxyl late last spring and great
explanations of different types of thryroid hormone (T3 and T4)/bramds
are

http://thyroid.about.com/gi/dynamic/offsite.htm?site=http://www.thyroid%2
Dinfo.com/articles/levoxyl.htm.  Some do better on natural hormone
(armour brand)

Many  also wrote that unstable levels are due to your body absorbing the
thyroid meds at a different rate, that you absorb the meds in the same
place that is destroyed from CD and that as your small intestine recovers
you will need less thryoid meds.

Other responses were:
3)Accidental gluten injestion changes absorbtion and you should adjust
your dosage when this happens.
4)Cabbage, glucosomine chondroten, calcium, fiber, iron and antacids
interfere with the absorbtion of thryroid hormone.
5)one person experienced similar problems during menopause
6)make sure that in fact you have been getting the same  product all
along.  Sometimes the pharmacist may be substituting another generic
brand, there could be other issues, too, besides gluten contamination

Other Recommendations:
1)look up www.forums.delphiforums.com/celiac/messages. Many speak about
thyroid issues there. There are kind and knowledgeable people there,
including doctors
with CD, and an extensive GF product list.
2)keep up with regular bloodtests so you can alter the medication very
easily
( her TSH has fluctuated wildly despite regular monitoring.  She has
Hashimoto's
 but have  been thyrotoxic (hyperthyroid) for almost half of the time and
is
 currently still taking ANTI-thyroid medication...  her endocrinologist
says
 it's unusual to vary so much but expects her to end up needing thyroxine

 like a  "regular" hypothyroid.    There  has been no specific research
into the effect of a gluten-free diet on  thyroid  function in people
with both conditions.
