skin or soft tissue infection
"I was prescribed Clarithromycin because I asked for an antibiotic which wouldn't upset my stomach.  Well it didn't do that, but by day 3 I was feeling sick most of the time and finding it hard to sleep.  I could have coped with that, but I also had the indescribable awful taste in my mouth which, although it doesn't sound much, became unbearable.  Everything I ate tasted of it, and my breath and urine smelt of it.  It's unfortunate, because the drug did seem to be working, but I had to go back to my doctor and ask to be prescribed something else.  I hope I never have to take this again."
