Off Label Uses
Based on the Centers for Disease Control and Prevention (CDC) sexually transmitted diseases treatment guidelines and the Canadian Guidelines on Sexually Transmitted Infections, ofloxacin is an effective and recommended treatment option for acute epididymitis likely caused by enteric organisms (as monotherapy). The CDC guidelines also recommend ofloxacin in combination with ceftriaxone for acute epididymitis likely caused by sexually transmitted chlamydia and gonorrhea and enteric organisms in men who practice insertive anal sex.
Data from a limited number of patients in an open-label, parallel assessment study suggest that ofloxacin, in combination with rifampin and minocycline (ROM), may be beneficial for the treatment of multibacillary leprosy [Villahermosa 2004]. Additional data may be necessary to further define the role of ofloxacin in this condition.
The World Health Organization Expert Committee on Leprosy (Eighth report) and the National Hansen's Disease Program also supports the use of ofloxacin as a second line agent in the treatment of multibacillary leprosy for patients who cannot take clofazimine (no longer commercially available in the US).
Data from a randomized double-blind trial comparing a daily dose of ofloxacin (in combination with daily doses of rifampin) for 4 weeks with the standard 6-month WHO-MDT regimen supports the use of a daily ofloxacin regimen for this condition [Balagon 2010]. Another randomized double-blind study suggests the use of single dose ofloxacin, in combination with rifampin and minocycline (ROM), may be beneficial as an alternative treatment regimen for paucibacillary leprosy in patients where careful follow-up for relapse is possible [Manickam 2012]. Additional trials may be necessary to further define the role of multiple and single dose ofloxacin regimens in paucibacillary leprosy. The World Health Organization Expert Committee on Leprosy and the National Hansen's Disease Program currently do not recommend ofloxacin for the treatment of paucibacillary leprosy.
Spontaneous bacterial peritonitis (treatment)
According to national and international guidelines regarding treatment of spontaneous bacterial peritonitis (SBP), ofloxacin may be considered as an alternative therapy to IV third-generation cephalosporins in patients with uncomplicated SBP who are not infected with a suspected quinolone-resistant organism. If fluoroquinolone-resistant, gram-negative bacteria are suspected as the causative organisms, when fluoroquinolones have been used for prophylaxis, or when patients are located in areas where incidence of quinolone-resistant bacterial infections are high, cefotaxime is the treatment of choice.
Based on the Infectious Diseases Society of America Guidelines for the Practice of Travel Medicine and the American College of Gastroenterology (ACG) Guideline for the Diagnosis, Treatment, and Prevention of Acute Diarrheal Infections in Adults, ofloxacin is an effective and recommended fluoroquinolone for antibiotic treatment of traveler’s diarrhea.
Hypersensitivity to ofloxacin, other quinolones, or any component of the formulation
Nongonococcal (due to Chlamydia trachomatis): 300 mg every 12 hours for 7 days
Gonococcal (acute, uncomplicated): 400 mg as a single dose; Note: As of April 2007, the CDC no longer recommends the use of fluoroquinolones for the treatment of uncomplicated gonococcal disease.

Likely caused by enteric organisms: 300 mg twice daily for 10 days (CDC [Workowski 2015]) or 200 mg twice daily for 14 days (Canadian STI Guidelines 2008 [Update 2014])
Likely caused by sexually transmitted chlamydia and gonorrhea and enteric organisms in men who practice insertive anal sex: 300 mg twice daily for 10 days in combination with ceftriaxone (CDC [Workowski 2015])
Leprosy (multibacillary) (off-label use): Oral: 400 mg once daily (in combination with dapsone and rifampin) for 12 months (WHO 2012) or alternatively, 400 mg once monthly (in combination with monthly rifampin and minocycline) for 24 months (Villahermosa 2004; WHO 1998; WHO 2012).
Leprosy (paucibacillary) (off-label use): Oral:
Multiple-dose regimen: 400 mg once daily (in combination with rifampin) for 4 weeks (Balagon 2010).
Single-dose regimen: 400 mg as a single dose (in combination with single doses of rifampin and minocycline) (Manickam 2012). Note: Found to be less effective than standard WHO multiple drug therapy (WHO-MDT) for paucibacillary leprosy; should only be used if close follow-up of relapse is possible (Manickam 2012; Setia 2011).
Spontaneous bacterial peritonitis (off-label use): Oral: 400 mg twice daily (AASLD [Runyon 2012]; Navasa 1996)

If symptoms not resolved after 24 hours, continue with a 3-day therapy course. A 3-day course of therapy is recommended in patients with fever or dysentery; enteric infection due to Shigella dysenteriae is an exception and a 5-day treatment duration is superior to single dose or 3-day regimens (ACG [Riddle 2016]). Note: Fluoroquinolone resistance is increasing; azithromycin may be preferred, particularly in regions such as southeast Asia or India with a high prevalence of Campylobacter (ACG [Riddle 2016]).

Exceptions: Zinc Chloride. Consider therapy modification
Some quinolones may produce a false-positive urine screening result for opioids using commercially-available immunoassay kits. This has been demonstrated most consistently for levofloxacin and ofloxacin, but other quinolones have shown cross-reactivity in certain assay kits. Confirmation of positive opioid screens by more specific methods should be considered.

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).
• CNS effects: Tremor, restlessness, confusion, and very rarely hallucinations, increased intracranial pressure (including pseudotumor cerebri) or seizures may occur; use with caution in patients with known or suspected CNS disorder. Discontinue in patients who experience significant CNS adverse effects (eg, dizziness, hallucinations, suicidal ideations or actions).
• 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, sometimes fatal, 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.
• Peripheral neuropathy: Peripheral neuropathy has been reported (rare); may occur soon after initiation of therapy and may be irreversible; discontinue if symptoms of sensory or sensorimotor neuropathy occur.
• 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.
• 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.
• Tendon inflammation/rupture: [US Boxed Warning]: There have been reports of tendon inflammation and/or rupture with quinolone antibiotics; risk may be increased with concurrent corticosteroids, organ transplant recipients, and in patients >60 years of age. Rupture of the Achilles tendon sometimes requiring surgical repair has been reported most frequently; but other tendon sites (eg, rotator cuff, biceps) have also been reported. Strenuous physical activity may be an independent risk factor for tendonitis. Discontinue at first sign of tendon inflammation or pain. May occur even after discontinuation of therapy.
• Hepatic impairment: Use with caution in patients with hepatic impairment.
• Myasthenia gravis: [US Boxed Warning]: May exacerbate muscle weakness related to myasthenia gravis. Cases of severe exacerbations, including the need for ventilatory support and deaths have been reported; avoid use in patients with myasthenia gravis.
• Renal impairment: Use with caution in patients with renal impairment; dosage adjustment required. May increase risk of tendon rupture.
• Rheumatoid arthritis: Use with caution in patients with rheumatoid arthritis; may increase risk of tendon rupture.
• Seizures: Use with caution in individuals at risk of seizures (CNS disorders or concurrent therapy with medications which may lower seizure threshold). Potential for seizures, although very rare, may be increased with concomitant NSAID therapy.
• Syphilis: Since ofloxacin 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. Note: As of April 2007, the CDC no longer recommends the use of fluoroquinolones for the treatment of uncomplicated gonococcal disease.
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.
Monitor CBC, renal and hepatic function periodically if therapy is prolonged.
Pregnancy Risk Factor
Adverse events have been observed in some animal reproduction studies. Ofloxacin crosses the placenta and produces measurable concentrations in the amniotic fluid. Serum concentrations of ofloxacin may be lower during pregnancy than in nonpregnant patients (Giamarellou 1989). Based on available data, an increased risk of teratogenic effects has not been observed following ofloxacin use during pregnancy (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 vomiting or nausea. Have patient report immediately to prescriber signs of kidney problems (urinary retention, hematuria, change in amount of urine passed, or weight gain), signs of liver problems (dark urine, fatigue, lack of appetite, nausea, abdominal pain, light-colored stools, vomiting, or jaundice), signs of tendon inflammation or rupture (pain, bruising, or swelling in the back of the ankle, shoulder, hand, or other joints), 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 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 high blood sugar (confusion, fatigue, increased thirst, increased hunger, polyuria, flushing, fast breathing, or breath that smells like fruit), signs of low blood sugar (dizziness, headache, fatigue, feeling weak, shaking, tachycardia, confusion, increased hunger, or sweating), 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), angina, tachycardia, abnormal heartbeat, dizziness, passing out, chills, tinnitus, thrush, muscle pain, muscle weakness, hallucinations, nightmares, insomnia, vision changes, seizures, severe headache, severe loss of strength and energy, tremors, abnormal gait, shortness of breath, vaginitis, bruising, bleeding, or signs of Clostridium difficile (C. diff)-associated diarrhea (abdominal pain or cramps, severe diarrhea or watery stools, or bloody stools) (rare) (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.
