Re: antibiotics and diflucan.. wait or not?
They work on two separate mechanisms of action. The antibiotic is to kill bacteria (all bacteria, including the good bacteria in your vagina which is what caused the yeast infection in the first place), while the diflucan is an anti-fungal, to kill fungus, which is what the yeast infection is.
While I've read that certain antibiotics perhaps may not be good with diflucan, I've ALWAYS taken them together, because I didn't want to deal with the yeast infection.
As to how long it takes, that I'm not sure of. It seemed to me like it took forever, because of how uncomfortable I was. But it may have only taken a day or two. I ended up getting monistat 3 in addition to the diflucan to help me a little. It came with an external cream that you use to help with the itching, which was really helpful. Look for the one that has the external cream in the box to apply as needed. It really makes a difference.
