Clarithromycin
"Was first prescribed this on my discharge from the hospital with pneumonia. Had me feeling great within a few days. Just had it prescribed again to clear up an ear infection and a little bit of a chest infection starting. Same thing, cleared up in days. Only down side is the metallic taste in the mouth. Some people suggest taking it at night to avoid that but sometimes I will wake up because of how awful it is. I also always make sure to take with yogurt to help ease my stomach."
