For those that have been having problems finding this at a reasonable price in the US it is available in Canada. I have not received my order yet. I actually bought it from 2 places as I found a really good price after I ordered from one. The price was $15 for 100 one place and $35 at the other. Here it is almost $90 now. It used to be a generic copay but a company discontinued it so now it is not under most prescription programs as a generic. In my case it is not available even with a copay.
