@wisco50 - I'm pretty sure this medication is not available OTC in Canada as I just had a prescription filled. It is compounded where I buy it (Walmart Pharmacy), and does not come in a tube. It was prescribed for me to help control arthritic pain. Sometimes it does the trick, sometimes I need to supplement it. It does not work well on the SFN because it's mostly the soles of my feet (burning) and it seems that the skin in that area is too thick for the cream to penetrate.
