I took Avelox five years ago to clear up an sinus infection that kept coming back every 2-3 weeks. I was prescribed regular antibiotics each time, it would go away, and then come right back. To get rid of it for good, my doctor prescribed me 400mg of Avelox, one per day for five days. It totally wiped out the infection and it never came back. Awesome, right?
Unfortunately it also destroyed most of the bacteria in my stomach leading to a bad case of c.diff for 2 weeks and permanent lactose intolerance.
It did exactly what I needed, but the price was very high indeed. Though my health has been better since then, I still get sick 2-3 times a year. The duration lasts longer than for most people, but I don't care. I do not take antibiotics anymore. If I ever do, it will need to be a life threatening condition.
