bladder infection
"Only negative experiences I've had with this medication are drowsiness (not really an issue if only taking at night as a preventative )and one time I forgot about the avoid alcohol thing and had one drink. I got the worst indigestion and nausea ever and it lasted for days. Otherwise a great medication that gets rid of the urinary tract infection as a treatment and has been wonderful as a prophylaxis to keep UTI's at bay."
