Hi I am on Azithromycin for bronchitis which has certainly helped to relieve my cough, breathing, airways etc. I started to feel relief within a few hours of taking the first pill, I am now onto day 5. But I feel pretty wiped out, lose of appetite, ache in lower back, slight tooth and headache , no energy generally feeling unwell and spent the past few days in bed. I have another 17 tablets to take shall I go with it or should I be worried about these side affects .
