bronchitis
"My pulmonary Doctor ordered this (Doxycycline) for me after being treated at home, for a few months and then I was   placed in a hospital for 4 days and then in a rehab hospital for 2 weeks. I finally took my first dose of doxycycline and the next day, I knew I was going to get well. I remained in rehab for a total of 30 days with 2 times a day rehab. I know Doxycycline saved my life!
I give Doxycyclne a 10. I had NO side effects...all GOOD EFFECTS!"
