Clarithromycin
""I am taking Clarithromycin 500mg.I have had a chest infection for over two weeks with no improvement so my G.P prescribed me these antibiotics. Although I have felt better and my chest is not so bad I have been experiencing the side effects from this medication. I have been experiencing very bad dreams - lucid and frightening to the point I don't want to go to sleep at night. I also have an awful metallic taste in my mouth that makes everything I eat or drink taste horrid. I have been experiencing stomach discomfort - aching/pain in stomach with mild diarrhoea. The worst thing I have experienced so far is the racing heartbeat. I'm considering stopping these tablets as the side effects are far to worrying."
