My son was prescribed Biaxin XL for bronchitis. After the first day taking it he began feeling very moody. Crying all the time, not sleeping. Then the paranoia set in. Feelings of wanting to hurt himself. Kept saying he felt like he was losing his mind. Not in touch with reality anymore. Saying he felt like something was eating him from the inside out. Finally after looking up on the computer was able to discover it was this horrible medicine. Had he taken his ten day dosage I am very afraid he would not be here with me today. STAY AWAY FROM THIS HORRIBLE DRUG! IT SHOULD BE TAKEN OFF THE MARKET, AND THE DOCTORS PRESCRIBING IT SHOULD BE MADE AWARE OF THE POTENTIAL HAZARDS THAT COULD HAPPEN BY PRESCRIBING IT!!!!!!!!!!!!!!!
