bronchitis
"Prescribed Clarithromycin for bad chest infection.  After taking the first tablet I felt nauseous and a really bitter taste in the mouth.  This is day 5 out of 7 and the symptoms have not gone away.  Also had diarrhoea on second day and constant gurgling and wind in the stomach.  I have felt pretty awful the whole time. Persevering with medication as I am desperate to get rid of the awful chesty cough and feeling unwell but will never take it again.  Since reading previous posts some say to eat before a dose and also have some yoghurt before and after.  Wish there had been some better advice on the leaflet with this antibiotic.  I have never felt this ill taking an antibiotic before, it feels like poison."
