My consultant prescribed ethambutol and clarithromycin for my broncheictasis back in April. The brocheictasis was caused by a TB bug and the good news is that my last two sputum samples have been clear of the bug but unfortunately since taking these antibiotics I have experienced one infection after another which has meant numerous courses of GP antibiotics on top, (five since July). My immune system has obviously been destroyed by the consultants antibiotics and I've now stopped taking them. No doubt my consultant will be furious but I can't go on being ill every couple of weeks. Has anyone else been so badly affected by their meds?
