They should be. I was given a prescription for them when I was pregnant. If you want to double check ask your doctor. According to the list online from my doctor it is ok to use Gyne-Lotrimin and Monistat for yeast during pregnancy.
u can double check with your dr yes, but my dr usually prescribes a pill to take for yeast infection incase i get one after an antiboitic. So i did get one and took the pill. And it didn't work, so i called back and asked doc if i could take the OTC 7-day treatment, and he said yes.. And i did and it worked!! Cleared it right up!
