For Sinusitis "I have taken it many, many times for my chronic sinus infections, and it seems to be the only thing that ever gets rid of the infection. I do get stomach aches from it and nausea, but it does what it's supposed to."

"Great drug, one dose, and your UTI is pretty much gone, but so is all the other bacteria you need. This medication made me so violently ill. Vomiting, watery diarrhea, and stomach cramping. Had to pull over while driving to vomit (never had to do that before in my life, not even when I was pregnant). Thankfully, it has a short duration of activity in the body, so by the next day, I was okay. But this went straight into the garbage can after that."

For Sinusitis "This medicine works very well. I didn't have a yeast infection, nor did I have the upset stomach, which I usually have with antibiotics."
