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.

Interaction

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.

Food Interaction

  • Take with or without food. Food slightly alters kinetics but not to any clinically significant extent.

Volume of Distribution

Lerof 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. Lerof is known to penetrate well into skin tissue, fluids (e.g. blisters), lung tissue, and prostatic tissue, amongst others.

Half Life

The average terminal elimination half-life of levofloxacin is 6-8 hours.

Clearance

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.
