I am currently being treated for a uti and bacterial vaginosis with macrodantin and flagyl. My ob also gave me a script for diflucan because I always get a yeast infection with any antibiotic I take. I am on day 4 of a 7 day antibiotic treatment and I can feel a yeast infection coming on. I am wondering if I can take the diflucan while taking the macrodantin and flagyl or if I need to wait until I am completely done with the anitbiotics?
