Levofloxacin solution for infusion is administered by slow intravenous infusion once or twice daily. The dosage depends on the type and severity of the infection and the sensitivity of the causative pathogen. The duration of treatment varies according to the severity of the disease. Adult:
- Community-acquired pneumonia: 500 mg once or twice daily,
- Complicated urinary tract infections (including pyelonephritis): 250 mg once daily,
- Chronic bacterial prostatitis: 500 mg once daily,
- Skin and soft tissue infections: 500 mg twice daily
- Enteric fever: 500 mg once daily.
Levofloxacin can be used in children aged as low as 6 months. The usual dose for children in community acquired pneumonia is:
- Children aged 6 months to less than 5 years: 10 mg/kg b.i.d. (up to 500 mg per day) for 10 days,
- Children aged 5 years to 16 years: 10 mg/kg q.d. (up to 500 mg per day) for 10 days.
The usual dose for children in recurrent or persistent Acute Otitis Media is:
- Children aged 6 months to less than 5 years: 10 mg/kg per day (maximum dose: 500 mg/day) given twice daily for 10 days.
Paediatric Use: Levofloxacin is not recommended for children less than 6 (six) months of age.
Levofloxacin ophthalmic solution:
- Days 1 through 3: Instill one to two drops in the affected eye(s) every 30 minutes to 2 hours while awake and approximately 4 and 6 hours after retiring.
- Day 4 through treatment completion: Instill one to two drops in the affected eye(s) every 1 to 4 hours while awake.
0.5% ophthalmic solution:
- Days 1 and 2: Instill one to two drops in the affected eye(s) every 2 hours while awake, up to 8 times per day.
- Days 3 through 7: Instill one to two drops in the affected eye(s) every 4 hours while awake, up to 4 times per day.
Administration of Levofloxacin (solution for infusion) should be continued for a minimum of 48 to 72 hours after the patient has become febrile or evidence of bacterial eradication has been obtained. Levofloxacin solution for infusion is only intended for slow intravenous infusion; it is administered once or twice daily. The infusion time must be at least 30 minutes for 250 mg or 60 minutes for 500 mg Levofloxacin solution for infusion. It is possible to switch from an initial intravenous application to the oral route at the same dosage after a few days.
The most frequently reported adverse events were headache and a taste disturbance following instillation. Other adverse events included decreased/blurred vision, diarrhea, dyspepsia, fever, infection, instillation site irritation/discomfort, ocular infection, nausea, ocular pain/discomfort, and throat irritation.
The following measures should be taken during administration of Levofloxacin: While taking Levofloxacin adequate amount of water should be drunk to avoid risk of crystalluria. Dose adjustment should be exercised during Levofloxacin ingestion in presence of renal insufficiency & hepatic insufficiency.
While taking Levofloxacin adequate amount of water should be drunk to avoid risk of crystalluria. Dose adjustment should be exercised during Levofloxacin ingestion in presence of renal insufficiency & hepatic insufficiency.
Infusion of fluid should be immediately discontinued if rigor arises for any reason during the process. Do not use if the solution is cloudy, contains particles or after expiry date.
If an allergic reaction to levofloxacin occurs, discontinue the drug. Serious acute hypersensitivity reactions may require immediate emergency treatment. Oxygen and airway management should be administered as clinically indicated.
Prolonged use may result in overgrowth of non-susceptible organisms, including fungi. If superinfection occurs, discontinue use and institute alternative therapy. Patients should be advised not to wear contact lenses if they have signs and symptoms of corneal ulcer. Avoid contaminating the applicator tip with material from the eye, fingers or other source.
Specific drug interaction studies have not been conducted with this drug. However, the systemic administration of some quinolones has been shown to elevate plasma concentrations of theophylline, interfere with the metabolism of caffeine, and enhance the effects of the oral anticoagulant warfarin and its derivatives, and has been associated with transient elevations in serum creatinine in patients receiving systemic cyclosporine concomitantly.
- Take with or without food. Food slightly alters kinetics but not to any clinically significant extent.
Volume of Distribution
Levofloxacin is widely distributed in the body, with an average volume of distribution following oral administration between 1.09-1.26 L/kg (~89-112 L). Concentrations in many tissues and fluids may exceed those observed in plasma. Levofloxacin is known to penetrate well into skin tissue, fluids (e.g. blisters), lung tissue, and prostatic tissue, amongst others.
The average terminal elimination half-life of levofloxacin is 6-8 hours.
The average apparent total body clearance of levofloxacin ranges from 8.64-13.56 L/h, and its renal clearance ranges from 5.76-8.52 L/h. The relative similarity of these ranges indicates a small degree of non-renal clearance.
Pregnancy & Breastfeeding use
Levofloxacin is not recommended for use during pregnancy or nursing, as the effects on the unborn child or nursing infant are unknown.
Levofloxacin is contraindicated in patients with a history of hypersensitivity to Levofloxacin, quinolone antimicrobial agents, or any other components of this product.
Use in Children: From clinical studies, it is evident that Levofloxacin can be used in children aged as low as 6 months.The usual dose for children in community acquired pneumonia (CAP) is-
- Children aged 6 months to less than 5 years: 10 mg/kg b.i.d. (up to 500 mg per day) for 10 days.
- Children aged 5 years to 16 years: 10 mg/kg q.d. (up to 500 mg per day) for 10 days.
The usual dose for children in recurrent or persistent Acute Otitis Media (AOM) is Children aged 6 months to less than 5 years: 10 mg/kg per day (maximum dose: 500 mg/day) given twice daily for 10 days.
Levofloxacin exhibits a low potential for acute toxicity. However, in the events of an acute overdosage, the stomach should be emptied. The patients should be kept under observation and appropriate hydration should be maintained.
Store in a cool & dry place, protected from light. Keep out of the reach of children.
