FDA Black Box Warning
WARNING: SERIOUS ADVERSE REACTIONS INCLUDING TENDINITIS, TENDON RUPTURE, PERIPHERAL NEUROPATHY, CENTRAL NERVOUS SYSTEM EFFECTS AND EXACERBATION OF MYASTHENIA GRAVIS Fluoroquinolones, including levofloxacin, have been associated with disabling and potentially irreversible serious adverse reactions that have occurred together [see Warnings and Precautions (5.1) ] , including: Tendinitis and tendon rupture [see Warnings and Precautions (5.2) ] Peripheral neuropathy [see Warnings and Precautions (5.3) ] Central nervous system effects [see Warnings and Precautions (5.4) ] Discontinue levofloxacin immediately and avoid the use of fluoroquinolones, including levofloxacin, in patients who experience any of these serious adverse reactions [see Warnings and Precautions (5.1) ] Fluoroquinolones, including levofloxacin, may exacerbate muscle weakness in patients with myasthenia gravis. Avoid levofloxacin in patients with a known history of myasthenia gravis [see Warnings and Precautions (5.5) ] . Because fluoroquinolones, including levofloxacin, have been associated with serious adverse reactions [see Warnings and Precautions ( 5.1 to 5.15) ] , reserve levofloxacin for use in patients who have no alternative treatment options for the following indications: Uncomplicated urinary tract infection [see Indications and Usage (1.12) ] Acute bacterial exacerbation of chronic bronchitis [see Indications and Usage (1.13) ] Acute bacterial sinusitis [see Indications and Usage (1.14) ] . WARNING: SERIOUS ADVERSE REACTIONS INCLUDING TENDINITIS, TENDON RUPTURE, PERIPHERAL NEUROPATHY, CENTRAL NERVOUS SYSTEM EFFECTS AND EXACERBATION OF MYASTHENIA GRAVIS See full prescribing information for complete boxed warning . Fluoroquinolones, including levofloxacin, have been associated with disabling and potentially irreversible serious adverse reactions that have occurred together ( 5.1 ), including: Tendinitis and tendon rupture ( 5.2 ) Peripheral neuropathy ( 5.3 ) Central nervous system effects ( 5
Contraindications
4 CONTRAINDICATIONS Levofloxacin injection is contraindicated in persons with known hypersensitivity to levofloxacin, or other quinolone antibacterials [see Warnings and Precautions (5.3) ]. Known hypersensitivity to levofloxacin injection or other quinolones (4 , 5.7 )
Pregnancy & Breastfeeding
8.1 Pregnancy Pregnancy Category C. Levofloxacin was not teratogenic in rats at oral doses as high as 810 mg/kg/day which corresponds to 9.4 times the highest recommended human dose based upon relative body surface area, or at intravenous doses as high as 160 mg/kg/day corresponding to 1.9 times the highest recommended human dose based upon relative body surface area. The oral dose of 810 mg/kg/day to rats caused decreased fetal body weight and increased fetal mortality. No teratogenicity was observed when rabbits were dosed orally as high as 50 mg/kg/day which corresponds to 1.1 times the highest recommended human dose based upon relative body surface area, or when dosed intravenously as high as 25 mg/kg/day, corresponding to 0.5 times the highest recommended human dose based upon relative body surface area. There are, however, no adequate and well-controlled studies in pregnant women. Levofloxacin should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
