This new box warning via FDA is something i've been aware of for
some time in patients using Cipro
floxaxin, levaquin (levofloxacin), Moxifloxacin (Avelox), ofloxacin (floxin), gatifloxacin (tequin), and
i'm glad it'll be highlighted on labeling, showing it's increasing incidence:
risk of tendinitis and tendon rupture is further increased in those over age 60, in kidney, heart, and lung transplant recipients, and with use of concomitant steroid therapy.
