What is Factive?
Factive is a fluoroquinolone (flor-o-KWIN-o-lone) antibiotic that fights bacteria in the body.
Factive is used to treat different types of bacterial infections in the lungs.
Fluoroquinolone antibiotics can cause serious or disabling side effects. Factive should be used only for infections that cannot be treated with a safer antibiotic.
Factive may also be used for purposes not listed in this medication guide.
Factive may cause swelling or tearing of a tendon (the fiber that connects bones to muscles in the body), especially in the Achilles' tendon of the heel. This effect may be more likely to occur if you are over 60, if you use steroid medication, or if you have had a kidney, heart, or lung transplant.
Call your doctor at once if you have sudden pain, swelling, bruising, tenderness, stiffness, or movement problems in any of your joints. Rest the joint until you receive medical care or instructions.
