I've also used Diflucan for thrush and got it for $38 but it was at the discretion of my doctor and apparently they aren't really supposed to as Diflucan is for life threatening cases of thrush in immunocompromised people. You could go back and ask though, he/she the worst they can do is say no.

Some other things I found were diet. This plays a huge part in the thrush cycle. Cut out refined sugar and yeast as these are things that thrush needs to survive. I also agree with the other girls about probiotics. As well as taking these orally I also put Inner Health Plus powder on my nipples, alternating between this and the Daktarin gel.

Definatly agree with Marydean on getting a swab done as I ended up having a staph infection, the symptoms are the same.
I was the opposite to Marydean with treatment though and couldn't stand the nilstat as it was to sticky and my nipples kept getting stuck to my breast pads.

Anyway good luck. There is another thread in the bf section about thrush ATM with heaps more suggestions.
