As a follow-up to my question as to how to rid of stubborn sinus infection that has gotten on one side of my nose worst than better, my doctor has now put me now Ceflin 250 mg. twice a day, plus prednisone for 5 days twice a day . As previously mentioned, I have taken Avelox 400 mg. for 7 days and 8 days of Levaquin 250 mg. twice day. I also just saw a report yesterday about antibotics not really helpful for sinus infection. Have you read this? I believe it was small study that was done in Britain. If antibotics are now used to treat sinus infections, how will doctor treat the infections. Thanks so much.
