The reason people say its best to see a doctor is because what many people simply call a "yeast infection," could actually be a bacterial or parasitic infection. A true yeast infection is fungal, like athlete’s foot. You really can’t effectively treat a vaginal infection without knowing what kind of bug you’re trying to kill. If its bacterial and you use Monistat, you knock out any fungus in there which might have been competing with the bacteria for resources, and now the bacterial infection and your symptoms are worse.

I personally have had more success with taking probiotics. Take an enteric-coated variety, and eat more fiber. You can even insert an acidophilus capsule into the business area for a day or two. That always helps me because even if its fungal, bacterial, or parasitic, the "good" bacteria seem to outcompete any offending bugs. You may also try a different antifungal, but if Monistat-7 didn’t work, I personally doubt a different brand would work any differently, but it all depends on the active ingredient and the dose.

Diflucan (fluconazole) tablets are effective for fungal yeast infections, but they are by prescription only so you’ll have to see a Dr. or visit a Planned Parenthood if you want to go that route. Good luck!

What has been the best over the counter yeast infection treatment for you? I need help with choosing one.?
I have had frequent yeast infections and I have tried the Monistat 7-day cream pack, but it clearly hasn’t been strong enough. Don’t tell me I need to go to the doctor please, I’m not going to result to that for quite awhile. So if you could give me suggestions on a better yeast infection treatment, it’d be greatly appreciated.
