It is an extremely harsh drug (it's what they use to kill Anthrax), has a number of nasty side effects (including the possibility of spontaneous tendon/ligament failure) and should really be reserved for life-threatening infections, we're running out of drugs that virulent bacteria aren't resistant to. I had to take it for a severe throat infection that was giving me 102-104 fevers, but I won't again if I can avoid it. It gave me tendonitis in my wrist and elbow for a week or two afterward, before I knew that that was a side-effect. Anyway, that and two other rounds of antibiotics this past year brought on the double whammy of a bacterial infection and a yeast infection back to back. My whole ph was just completely screwed despite eating a low-sugar, vegetarian diet and lots of yogurt for years. Inserting yogurt, however, worked perfectly. I used organic with live cultures from a local farm and just inserted about a teaspoon (not frozen) each night for four nights. Lo and behold, weird smell and uncharacteristic discharge are totally gone. I recommend spreading some around the whole vulva/perineal/anal area. The bad bacteria are getting into the vagina from elsewhere, you know, and the yeast must spread at such close proximity.
