I have a sinus infection and got 2 2 diff. Scripts fron 2 diff dr. 1. For levaquin (levofloxacin) and 1 for predisone which will work better?

Bad idea. Seeing different doctors for the same problem is okay as long as they know what other treatments you have been receiving. Keeping them in the dark on other treatments is potentially hazardous. In your case, Levaquin (levofloxacin) and steroids together can lead to certain issues with your tendons that the doctor would have counseled you about. I would pick your favorite of the 2 mds and ask what they think.
