Clarithromycin
"After 4 days of thinking I had a severe cold, I was diagnosed with Bronchitis (possible walking pneumonia) at the Urgent Care. Was prescribed Proair and Clarathromycin 500mg. I was also given Musinex to help loosen the mucus. I started with the first dose at 9 pm and by the next morning I felt a whole lot better. It works really fast! I like the fact it doesn't smell like smelly hard boiled eggs like some other antibiotics, to me it smelled like Jordan almonds which I like :) I'm on my third day and I can acually take a deep cleansing breath without any wheezing or coughing. I did not have any of the side effects except for being a little lathargic."
