This winter I had a bad flu that got worse every time I took
medication -- I was taking Benelyn (sp?).  This cough syrup was full
of grain alcohol, making me sicker than I needed to be.  My
pharmacist looked through his "big book of drugs" and noticed that
almost all the Tylenol products were listed under Gluten Free drugs.
N.B.  There may be a difference in processing between Canada & US, so
check with your own pharmacist.  But the Tylenol Flu caplets worked
like a charm for me.
