Im taking levaquin (levofloxacin) and now i think i have a yeast infection, is it ok to buy over-the-counter meds to treat it while taking the antibiotic?

YES: Yeast infections are very common to acquire when taking antibiotics. Generally speaking, it is recommedned to start the treatment after the anti-biotics, or the yeast infection may simply return. The otc meds are fine to try, and several of them used to be rx in the not so distant past.

Common problem: When taking any antibiotic, the normal bacterial flora of the vagina can be temporarily reduced. Yeast will overgrow, causing symptoms of itching and discharge. In general, it is fine to try an over-the-counter yeast medication. It used to be available only by prescription. Now you can get it on your own. Naturally, stop the yeast medicine if your symptoms worsen, or you seem to be allergic!
