– Levofloxacin Injection should only be administered by slow intravenous infusion over a period of 60 or 90 minutes depending on the dosage.
– While administrating Levofloxacin, adequate amount of water should be taken to avoid concentrated form of urine.
– Dose adjustment should be exercised during Levofloxacin administration in presence of renal insufficiency.
Levoxin eye drops should not be injected subconjunctially, nor should it be introduced directly into the anterior chamber of the eye. Avoid contaminating the applicator tip with material from the eye, fingers or other source.
Use in Pregnancy & Lactation
Levofloxacin is not recommended for use during pregnancy or nursing, as the effects on the unborn child or nursing infant are unknown.
Drug Interaction
No quinolone should be co-administered with any solution containing multivalent cations, e.g., magnesium, through the same intravenous line. Antacids, Iron and Adsorbents reduce absorption of Levofloxacin. NSAID may increase the risk of CNS stimulation. Warfarin may increase the risk of bleeding.
Over Dose
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.
