I have bronchitis... I always have since i was a child. Every once in a while it flares back up and i always get prescribed a multitude of antibiotics. My mother is a nurse and she usually keeps Augmentin of Amoxicilin or some form of Antibiotic around for me. I am away from home and I am certain my Bronchitis has returned. I took some Augmentin a friend gave me without realizing it was expired. Will this make me sick or is the potency reduced. I need to know this because i'm a little bit frightened.
