Since a lot of reviews are relatively short-term, here's a pretty historical one for you... I ordered this in April 2016. It is now December 2022. I used it to treat BV 6.5 years ago and have had absolutely no problems since. When I got BV, I had never even had a yeast infection and had a weird amount of pride about my vaginal health, so I was really psychologically messed up about it and very determined to return to my previous bacterial balance as soon as possible. I had already read horror stories of the BV/YI cycle triggered by antibiotics, but I was fortunate to have a rather progressive gyno who prescribed me boric acid instead of antibiotics in the first place. Feel free to let that calm you down about putting an acid in your vagina (although you shouldn't be too worried--acids are not inherently harmful, and this is a very weak one anyway!). I initially used one size 00 capsule suppository every night for 10 days, which got rid of all of my symptoms after one use. However, my pH was back up to about 5 within a few days of stopping, which I knew was tracking towards relapse, so I kept going. At this point, I was VERY concerned about the bad bacteria becoming entrenched and forming a biofilm, so I may have overdone it, but I kept using one capsule nightly for about 3 months. After that, I weaned off to every other night for another 3 months, and then I stopped completely. No problems after that. In hindsight, I think I could've cut that time in half, but I had no negative effects and this stuff was so cheap and easy to use. The only side effect I experienced was a large amount of clear, odorless, watery discharge first thing in the morning. I'm surprised more people haven't mentioned that because it was shocking to me when it first happened! Maybe it doesn't happen to everyone, or maybe it was just the capsules I had, but don't be alarmed if that happens. Also, be aware that you will have an utterly odorless, tasteless vagina while you're using this. That may sound great when you're in the throes of BV, but it's almost eerie. When your healthy flora comes back, don't mistake it for a relapse! Hopefully this is helpful and gives you hope, even if you've already tried this but keep having to use it for maintenance. One of the worst parts of my BV experience was that I was constantly thinking about my vagina (not in a fun way) and how awful it felt to have something wrong with it, even when I was technically completely symptomless during my boric acid course. It took me a long time to stop being paranoid about it, but eventually I was able to trust that it was gone for good and I haven't thought about it in years. In fact, the only thing that prompted me to write this review is that I recently used some of the leftover boric acid to help kill some mold on a piece of wood! All this to say, I know how easily BV can take over your life, but this stuff will give it back to you. And a big thanks to this product in particular for being so affordable and having the right consistency for this use!
