Giardia, flagyl resistance and quinacrine

A couple of cases of giardiasis have recently given us reason to suspect 
flagyl resistance.   Previously most suspected resistance we could 
attribute to non-compliance or reinfection.  Our problem is that quinacrine is 
getting harder and harder to get.   Here in Canada, Tinidazole is not an 
option.  Any other alternatives?  Any suggestions?
