Just try ordering it online. I have a prescription for a medication from my doctor that my insurance company won't pay for. The doctor's office won't send the prescription info to Canada, but I call a Canadian pharmacy and fax the script to them and it's sent to me.
I had a COTHer send me a care package of "beauty supplies" or something to that effect. It is OTC everywhere except here in the US. I have given away all of the tubes except one, it's so cheap relatively that whenever someone complains of pain I just give it to them. I am going to need another shipment soon.
