I have a post about piroxicam on our Medications forum here.

I think you should read it carefully and the links in it.

Piroxicam does not provide ANY advantage over any other of the traditional
NSAIDs (the older ones) and has a very high risk for bleeding episodes.
In fact it is hardly ever used anymore because of this risk.
Also just because it is once a day dosing, does not mean anything. (doctors sometimes think these are "stronger", but all that is gained is that if you have a reaction it will last all day).

One thing the new drug interactions do not yet mention, is that SSRI's increase bleeding tendencies...and piroxicam is the worst offender of that. Some pharmacies put NSAID warnings on their SSRI patients' bottles now.

So do be careful.

Thiamine has been used for many years and is not my idea per se.

This study should be interesting when completed.
It is unfortunate that its usefulness is eclipsed by drugs like Neurontin and Elavil.

Here is a monograph on Thiamine

If you want me to look up your drugs for you in the reference I use..concerning
nutrient depletions I can. You can PM me if you need privacy.
