Yeast Infection Medications During First Trimester


Dear Midwife,
I am currently 8 months pregnant. I was looking on the internet about treatment of yeast infections and have seen many articles that say medication should not be used in the first trimester. I am really worried.

When I was 6 weeks pregnant I my doctor prescribed a cream for me to use internally. Could this have hurt my baby? Would problems have shown up on my 5 month ultrasound? Was this safe since it was prescription? Thank you for your help.


Anti-fungal creams are usually Pregnancy Category B, and are used routinely for yeast infections during pregnancy. Not to worry!
