I have taken nystatin, hundreds of them when I first became ill, for many many months and it didn't cure me. I tried the diflucan for about 1 week or ten days, something like that, and it did nothing either. I think the cost about 20 years ago when I did all that was 250 canadian or it might have been 5 hundred, don't quite remember as my father paid for it.
Maybe do a search on this forum to see if anyone felt a benefit from the drug.
