I think the reason I had such trouble was I was on antibiotics for 6 weeks. 10 days on Keflex(cephalexin). It seemed like it was getting better around day 8 then day 10(when I was supposed to be done with it) I woke up and it looked worse than before I started taking it

Then they put me on Ceftin(can't remember the generic name) for a 21 day course since the infection was so bad. On day 17 I went back to the doctor because yet again after starting to get better it went bad again. SOOOOO that's when they put me on clindamycin and it worked like a charm in 14 days.

BUT I was on the antibiotics so long my tummy/bowels were tore to pieces and I felt like I was starting to get a yeast infection. So called the doc and she told me to talk to the pharmacist to find a GOOD probiotic that I could take while on the antibiotics and within 7 days the tummy trouble and lady trouble cleared up.

Hopefully you won't have to be on the antibiotics long enough to worry about it
