Ciprofloxacin
"This will be my 2nd experience with cipro first was for a injection infection (7 day prescription vs prostatitis 6 weeks).  My infection was considered fairly serious so I think I will continue to see improvement until week 3.  Doctors generally tone down the sides handing this to you, but will admit sides "yea you'll have that" when u get them.

I warn the side effects can be terrible.  Everyone reacts a bit different.  I know anytime I take this by day 4's dose I begin to have soft stool that burns the anus and causes skin bleeding.  Excessive wiping is bad as it only irritates - try some petroleum to the area.  Also this antibiotic is really bad on healthy gut bacteria.  Recommend yogurt and probiotic.  Keep the 2 hour calcium rule in mind and drink crazy amounts of water."
