            Warnings

            Black Box Warnings

            Fluoroquinolones have been associated with disabling and potentially irreversible serious adverse reactions that have occurred together including: tendinitis and tendon rupture, peripheral neuropathy, and CNS effects

            Discontinue the drug immediately and avoid use of systemic fluoroquinolones in patients who experience any of these serious adverse reactions

            May exacerbate muscle weakness in patients with myasthenia gravis; avoid fluoroquinolones with known history of myasthenia gravis

            Serious adverse effects and limitations-of-use

            • Both oral and injectable fluroquinolones are associated with disabling side effects involving tendons, muscles, joints, nerves and the central nervous system
            • These side effects can occur hours to weeks after exposure to fluoroquinolones and may potentially be permanent
            • Discontinue the drug immediately and avoid use of systemic fluoroquinolones in patients who experience any of these serious adverse reactions
            • Because the risk of these serious side effects generally outweighs the benefits for patients with acute bacterial sinusitis, acute exacerbation of chronic bronchitis, and uncomplicated UTIs, that fluoroquinolones should be reserved for use in patients with these conditions who have no alternative treatment options
            • For some serious bacterial infections, including anthrax, plague, and bacterial pneumonia among others, the benefits of fluoroquinolones outweigh the risks and it is appropriate for them to remain available as a therapeutic option

            Contraindications

            All drugs or conditions that prolong QT interval

            Documented hypersensitivity to gemifloxacin or other fluoroquinolones

            Cautions

            May prolong QT interval

            May cause maculopapular rash

            Although not reported in gemifloxacin clinical trials, convulsions, increased intracranial pressure (including pseudotumor cerebri), and toxic psychosis reported with other fluoroquinolones

            Peripheral neuropathy: Sensory or sensorimotor axonal polyneuropathy affecting small and/or large axons resulting in paresthesias, hypoesthesias, dysesthesias, and weakness reported; peripheral neuropathy may occur rapidly after initiating and may potentially become permanent

            In prolonged therapy, perform periodic evaluations of organ system functions (eg, renal, hepatic, hematopoietic); adjust dose in renal function impairment; superinfections may occur with prolonged or repeated antibiotic therapy

            Not drug of first choice in pediatrics due to increased incidence of adverse events compared to controls, including arthropathy; no data exist for dose for pediatric patients with renal impairment (ie, CrCl <50 mL/min)

            Fluoroquinolones are associated with increased risk of tendinitis and tendon rupture in all ages, this risk is further increased in older patients usually over 60 yr, in patients taking corticosteroid drugs, and in patients with kidney, heart, or lung transplants

            Acute onset of retinal detachment increased 4.5-fold with oral fluoroquinolones in a single case-controlled study - JAMA 2012;307(13):1414-1419; another study disputes these findings (relative risk, 1.29) - JAMA 2013;310(20):2184-2190

            Pregnancy & Lactation

            Pregnancy Category: C

            Lactation: excretion in milk unknown; do not use unless benefit to mother outweighs risk

            Pregnancy Categories

            A:Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.

            B:May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk.

            C:Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done.

            D:Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk.

            X:Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist.

            NA:Information not available.

            Pharmacology

            Mechanism of Action

            Acts by inhibiting both DNA gyrase and topoisomerase IV, which are essential for bacterial growth. Because of this dual mechanism, MIC values remain in the susceptible range for some double mutants (eg, S pneumoniae)

            Absorption

            Bioavailability: 71%

            Peak Plasma Time: 0.5-2 hr

            Peak Plasma Concentration: 1.61 mcg/mL

            AUC: 9.93 mcg•hr/mL

            Distribution

            Protein bound: 60-70%

            Metabolism

            Hepatic (limited)

            Elimination

            Half-Life: 5-9 hr

            Dialyzable: yes (20-30%)

            Excretion: feces (60%); urine (40%)
