bronchitis
"I have SLE, and was prescribed Clarithromycin for respiratory/lung infection. I had  previously taken a course of antibiotics but it didn't work, and was thus prescribed Clarithromycin. 



The first two days I didn't feel better, i was nauseated, still coughing like crazy, and vomiting/hacking out phelgm every 5 mins.



On the third day, my coughing subsided moderately and I didn't seem to be producing much phelgm. 



But a metallic taste crept into my mouth and i was getting increasingly nauseous every time I took the medicine, to the extent that I vomited my food and perhaps the medication twice. It also gave me nightmares, hallucinations, palpitations, when I take it at night.



Now its day 5 and I'm considering stopping it altogether.."
