I use nystatin powder when I get oral thrush, but I find it very unlikely that a baby would agree to this med. I has a very strange taste that persists for a *long* time. Foods taste wierd for more than an hour. When I first tried to get it, my pharmacist provided me with a formula that included talc and shouldNONOT be used for internal applications but works great on athletes foot. I had to track down the source for the pure powder. What I found was Paddock Labs in Minneapolis. I don't have the address because my pharmacist is compelled to paste and tape instructions on top of the bottle label. I could get it if someone wants to email me privately.
