Yeast infection

I have a vaginal yeast infection that is not going away with home remedies, and I now have some pain in my breast when the baby is nursing.

I’m concerned that the yeast infection is spreading to the baby’s mouth, so I contacted our GP for a prescription for both of us.

He prescribed a nystatin oral suspension for both of us, which I’m sure is correct for the baby, but I’m wondering if anyone else has used this for a vaginal yeast infection before? Was is successful?

Some of what I’m reading says it’s not a common treatment for a vaginal yeast infection. I want to nip this is the bud before it gets bad, but I want to make sure that this is the right way to treat it.

Thanks in advance!
