Concerns related to adverse effects:
• Altered cardiac conduction: Fluoroquinolones may prolong QTc interval; avoid use in patients with a history of QTc prolongation, uncorrected hypokalemia, hypomagnesemia, or concurrent administration of other medications known to prolong the QT interval (including Class Ia and Class III antiarrhythmics, cisapride, erythromycin, antipsychotics, and tricyclic antidepressants).
• Glucose regulation: Fluoroquinolones have been associated with the development of serious, and sometimes fatal, hypoglycemia. These events have occurred most often in elderly patients with diabetes, but have also been reported in patients without a prior history of diabetes. Prompt identification and treatment of hypoglycemia is essential. Individual quinolones may differ in their potential to cause this effect. It was most evident with gatifloxacin (no longer marketed as s systemic formulation). Hyperglycemia has also been associated with the use of fluoroquinolones. Patients should be monitored closely for signs/symptoms of disordered glucose regulation.
• Hypersensitivity reactions: Severe hypersensitivity reactions, including anaphylaxis, have occurred with quinolone therapy. The spectrum of these reactions can vary widely; reactions may present as typical allergic symptoms (eg, itching, urticaria, rash, edema) after a single dose, or may manifest as severe idiosyncratic dermatologic (eg, Stevens-Johnson, toxic epidermal necrolysis), vascular (eg, vasculitis), pulmonary (eg, pneumonitis), renal (eg, nephritis), hepatic (eg, hepatic failure or necrosis), and/or hematologic (eg, anemia, cytopenias) events, usually after multiple doses. Prompt discontinuation of drug should occur if skin rash or other symptoms arise.
• Phototoxicity: Avoid excessive sunlight and take precautions to limit exposure (eg, loose fitting clothing, sunscreen); may cause moderate-to-severe phototoxicity reactions. Discontinue use if photosensitivity occurs.
• Serious adverse reactions: [US Boxed Warning]: Fluoroquinolones are associated with disabling and potentially irreversible serious adverse reactions that may occur together, including tendinitis and tendon rupture, peripheral neuropathy, and CNS effects. Discontinue norfloxacin immediately and avoid use of fluoroquinolones in patients who experience any of these serious adverse reactions. Patients of any age or without pre-existing risk factors have experienced these reactions; may occur within hours to weeks after initiation.
- CNS effects: Fluoroquinolones have been associated with an increased risk of CNS effects including seizures, increased intracranial pressure (including pseudotumor cerebri), and toxic psychosis; may also cause nervousness, agitation, insomnia, anxiety, nightmares, paranoia, dizziness, confusion, tremors, hallucinations, depression, and suicidal thoughts or actions. May occur following the first dose; discontinue immediately and avoid further use of fluoroquinolones in patients who experience these reactions. Use with caution in patients with known or suspected CNS disorder, or risk factors that may predispose to seizures or lower the seizure threshold.
- Peripheral neuropathy: Fluoroquinolones have been associated with an increased risk of peripheral neuropathy; may occur soon after initiation of therapy and may be irreversible; discontinue if symptoms of sensory or sensorimotor neuropathy occur. Avoid use in patients who have previously experienced peripheral neuropathy.
- Tendinitis/tendon rupture: Fluoroquinolones have been associated with an increased risk of tendonitis and tendon rupture in all ages; risk may be increased with concurrent corticosteroids, solid organ transplant recipients, and in patients >60 years of age, but has also occurred in patients without these risk factors. Rupture of the Achilles tendon has been reported most frequently; but other tendon sites (eg, rotator cuff, biceps, hand) have also been reported. Inflammation and rupture may occur bilaterally. Cases have been reported within hours or days of initiation, and up to several months after discontinuation of therapy. Strenuous physical activity, renal failure, and previous tendon disorders may be independent risk factor for tendon rupture. Discontinue at first sign of tendon pain, swelling, inflammation or rupture. Avoid use in patients with a history of tendon disorders or who have experienced tendinitis or tendon rupture.
• Superinfection: Prolonged use may result in fungal or bacterial superinfection, including C. difficile-associated diarrhea (CDAD) and pseudomembranous colitis; CDAD has been observed >2 months postantibiotic treatment.
• Myasthenia gravis: [US Boxed Warning]: May exacerbate muscle weakness related to myasthenia gravis; avoid use in patients with known history of myasthenia gravis. Cases of severe exacerbations, including the need for ventilatory support and deaths have been reported.
• Renal impairment: Use caution with renal impairment; dose adjustment required. May increase risk of tendon rupture.
• Rheumatoid arthritis: Use with caution in patients with rheumatoid arthritis; may increase risk of tendon rupture.
• Syphilis: Since norfloxacin is ineffective in the treatment of syphilis and may mask symptoms, all patients should be tested for syphilis at the time of gonorrheal diagnosis and 3 months later.
Concurrent drug therapy issues:
• Drug-drug interactions: Potentially significant interactions may exist, requiring dose or frequency adjustment, additional monitoring, and/or selection of alternative therapy. Consult drug interactions database for more detailed information.
• Elderly: Adverse effects (eg, tendon rupture, QT changes) may be increased in the elderly.
• G6PD deficiency: Hemolytic reactions may (rarely) occur with quinolone use in patients with latent or actual G6PD deficiency.
• Pediatric: Safety and efficacy have not been established in children; other quinolones have caused transient arthropathy in children.
• Appropriate use: [US Boxed Warning]: Reserve use of norfloxacin for treatment of uncomplicated urinary tract infections, including cystitis, for patients who have no alternative treatment options because of the risk of disabling and potentially serious adverse reactions (eg, tendinitis and tendon rupture, peripheral neuropathy, CNS effects).
Monitor CBC, renal and hepatic function periodically if therapy is prolonged.
Pregnancy Risk Factor
Adverse events have been observed in some animal reproduction studies. Norfloxacin crosses the placenta, distributing to cord blood and amniotic fluid (Wise 1984). Based on available data, an increased risk of teratogenic effects has not been observed following norfloxacin use during pregnancy (Bar-Oz 2009; Padberg 2014).
• Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)
• Patient may experience abdominal cramps, nausea, vomiting, heartburn, or diarrhea. Have patient report immediately to prescriber signs of kidney problems (urinary retention, hematuria, change in amount of urine passed, or weight gain), signs of tendon inflammation or rupture (pain, bruising, or swelling in the back of the ankle, shoulder, hand, or other joints), signs of depression (suicidal ideation, anxiety, emotional instability, or confusion), signs of liver problems (dark urine, fatigue, lack of appetite, nausea, abdominal pain, light-colored stools, vomiting, or jaundice), signs of nerve problems (sensitivity to heat or cold; decreased sense of touch; burning, numbness, or tingling; pain, or weakness in the arms, hands, legs, or feet), signs of high blood sugar (confusion, fatigue, increased thirst, increased hunger, polyuria, flushing, fast breathing, or breath that smells like fruit), signs of Stevens-Johnson syndrome/toxic epidermal necrolysis (red, swollen, blistered, or peeling skin [with or without fever]; red or irritated eyes; or sores in mouth, throat, nose, or eyes), signs of low blood sugar (dizziness, headache, fatigue, feeling weak, shaking, tachycardia, confusion, increased hunger, or sweating), angina, tachycardia, abnormal heartbeat, dizziness, passing out, severe loss of strength and energy, hallucinations, agitation, nightmares, seizures, vision changes, severe headache, shortness of breath, bruising, bleeding, chills, tinnitus, tremors, abnormal gait, muscle pain, muscle weakness, vaginitis, thrush, or signs of Clostridium difficile (C. diff)-associated diarrhea (abdominal pain or cramps, severe diarrhea or watery stools, or bloody stools) (HCAHPS).
• Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
