I have used refrigerated acidophilus for this problem in the past. It wiped it out right away. The bottle said to take 1 day for maintenance, but when I would get BV I would take 3 a day until it cleared up. I think it only took a few days to work. I also took it at the beginning of a bladder infection. Cleared that up to. Haven't used creams or Antibiotics in years due to acidophilus doing the trick. Hope this helps.
