I have had Bronchiectasis for about 2 years. I started a prescription of Lexofloxacin for 7 days.

After three days feeling much better I quit coughing up mucous. My question is WHY?

I am happy about it, but I can't keep taking an antibiotic to feel good. I am on a 10 day vacation and didn't want to be sick the whole time.

All insight appreciated.

Thanks john
