                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 fluoroquinolones are associated with disabling adverse 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
                • Because the risk of these serious adverse effects generally outweighs the benefits for patients with acute bacterial sinusitis, acute exacerbation of chronic bronchitis, and uncomplicated UTIs, 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

                Hypersensitivity to delafloxacin or its components or other fluoroquinolones

                Cautions

                Prescribing an antibiotic in the absence of proven or strongly suspected bacterial infection is unlikely to provide benefit and increases risk developing drug-resistant bacteria

                Increased risk of aortic aneurysm and dissection within 2 months following fluoroquinolone use observed in epidemiologic studies, particularly in elderly patients; etiology has not been identified; reserve use in patients with known or at greater risk for aortic aneurysm only when there are no alternative antibacterial treatments available

                Blood glucose disturbances reported with fluoroquinolones, including symptomatic hyperglycemia and hypoglycemia, usually in diabetic patients receiving concomitant treatment with an oral hypoglycemic agent (eg, glyburide) or with insulin; careful blood glucose monitoring recommended; severe cases of hypoglycemia resulting in coma or death reported with other fluoroquinolones; if hypoglycemic reaction occurs in a patient being treated with this medication, discontinue therapy and initiate appropriate therapy immediately

                Disabling and potentially irreversible serious reactions

                • Fluoroquinolones are associated with disabling and potentially irreversible serious adverse reactions from different body systems, including tendinitis, tendon rupture, arthralgia, myalgia, peripheral neuropathy, and CNS effects (eg, hallucinations, anxiety, depression, insomnia, severe headaches, confusion); patients of any age or without pre-existing risk factors have experienced these adverse reactions
                • Discontinue therapy immediately at first signs or symptoms of any serious adverse reaction; in addition, avoid use of fluoroquinolones, including this drug, in patients who have experienced any of these serious adverse reactions associated with fluoroquinolones

                Tendinitis and tendon rupture

                • Risk of tendinitis and tendon rupture in all ages; the Achilles tendon is most frequently involved, but rupture also reported with the rotator cuff, hand, biceps, thumb, and other tendons; tendinitis or tendon rupture can occur, within hours or days of starting a fluoroquinolone, or as long as several months after completion of fluoroquinolone therapy; tendinitis and tendon rupture can occur bilaterally
                • This risk of developing fluoroquinolone-associated tendinitis and tendon rupture is increased in patients > 60 years of age, in patients taking corticosteroid drugs, and, in patients with kidney, heart, and lung transplant; other factors that may independently increase risk of tendon rupture include strenuous physical activity, renal failure, and previous tendon disorders such as rheumatoid arthritis; tendinitis and tendon rupture have also occurred in patients taking fluoroquinolones who do not have the above risk factors

                Peripheral neuropathy

                • Fluoroquinolones are associated with increased risk of peripheral neuropathy; sensory or sensorimotor axonal polyneuropathy affecting small and/or large axons resulting in paresthesias, hypoesthesias, dysesthesias, and weakness reported
                • Discontinue therapy immediately if patient experiences symptoms of peripheral neuropathy including pain, burning, tingling, numbness, and/or weakness or other alterations of sensation including light touch, pain, temperature, position sense, and vibratory sensation and/or motor strength in order to minimize the development of an irreversible condition
                • Symptoms may occur soon after initiation of fluoroquinolones and may be irreversible in some patients; avoid therapy in patients who have previously experienced peripheral neuropathy

                Exacerbation of myasthenia gravis

                • Fluoroquinolones have neuromuscular blocking activity and may exacerbate muscle weakness in persons with myasthenia gravis; post-marketing serious adverse reactions, including death and requirement for ventilator support, have been associated with fluoroquinolone use in persons with myasthenia gravis; avoid therapy in patients with known history of myasthenia gravis

                Hypersensitivity reactions

                • Serious and occasionally fatal hypersensitivity (anaphylactic) reactions, some following the first dose, reported in patients receiving fluoroquinolone therapy; some reactions were accompanied by cardiovascular collapse, loss of consciousness, tingling, pharyngeal or facial edema, dyspnea, urticaria, and itching
                • Hypersensitivity reactions reported in patients receiving therapy; these reactions may occur after first or subsequent doses of this drug; discontinue therapy at first appearance of a skin rash or any other sign of hypersensitivity

                Clostridium difficile-associated diarrhea

                • Clostridium difficile-associated diarrhea (CDAD) reported in users of nearly all systemic antibacterial drugs, including this medication, with severity ranging from mild diarrhea to fatal colitis; treatment with antibacterial agents can alter normal flora of colon and may permit overgrowth of C. difficile
                • C. difficile produces toxins A and B, which contribute to development of CDAD; hypertoxin-producing strains of C. difficile cause increased morbidity and mortality, as these infections can be refractory to antibacterial therapy and may require colectomy
                • CDAD must be considered in all patients who present with diarrhea following antibacterial use; careful medical history is necessary because CDAD has been reported to occur more than 2 months after administration of antibacterial agents
                • If CDAD is suspected or confirmed, ongoing antibacterial use not directed against C. difficile should be discontinued, if possible; appropriate measures such as fluid and electrolyte management, protein supplementation, antibacterial treatment of C. difficile, and surgical evaluation should be instituted as clinically indicated

                Central nervous effects

                • If the following adverse effects occur, discontinue delafloxacin immediately and institute appropriate therapy
                • Psychiatric effects
                  • Associated with increased risk of psychiatric adverse reactions, including: toxic psychosis, hallucinations, paranoia, depression, suicidal thoughts or acts, delirium, disorientation, confusion, disturbances in attention, anxiety, agitation, nervousness, insomnia, nightmares, or memory impairment; may occur after the first dose
                  • If reactions occur, discontinue therapy and institute appropriate measures
                • CNS effects
                  • Associated with increased risk of seizures, increased intracranial pressure (including pseudotumor cerebri), dizziness, and tremors
                  • Assess benefits and risks of use in patients with known or suspected CNS disorders (eg, severe cerebral arteriosclerosis, epilepsy) or in the presence of other risk factors that may predispose to seizures or lower the seizure threshold
                  • If reactions occur, discontinue therapy and institute appropriate measures

                Drug interaction overview

                • Do not coadminister IV delafloxacin in the same IV line with any solution containing multivalent cations (eg, magnesium)
                • Chelation
                  • Fluoroquinolones form chelates with alkaline earth and transition metal cations
                  • Delafloxacin PO administration with antacids containing aluminum or magnesium, with sucralfate, with metal cations (eg, iron), or with multivitamins containing iron or zinc, or with formulations containing divalent and trivalent cations (eg, didanosine buffered tablets for oral suspension or the pediatric powder for oral solution), may substantially interfere with the absorption and decrease systemic exposure
                  • Administer delafloxacin at least 2 hr before or 6 hr after the aforementioned agents

                Pregnancy

                Pregnancy

                Data are limited regarding use in pregnant women and are insufficient to inform a drug-associated risk of major birth defects and miscarriages

                Animal studies

                • When administered PO to rats during organogenesis, no malformation or fetal death were observed at doses up to 7 times the estimated clinical exposure based on AUC
                • When rats were dosed with the IV form in late gestation and during lactation, no adverse effects on offspring were observed

                Lactation

                Unknown if distributed in human breast milk

                Excreted in the breast milk of rats

                Consider the developmental and health benefits of breastfeeding along with the mother’s clinical need for the drug, and any potential adverse effects on the breastfed infant from the drug or from the underlying maternal condition

                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.
