Dosage in Adult Patients with Normal Renal Function

The usual dose of Levofloxacin Oral Solution is 250 mg, 500 mg, or 750 mg administered orally every 24 hours, as indicated by infection and described in Table 1.

These recommendations apply to patients with creatinine clearance ≥ 50 mL/min. For patients with creatinine clearance <50 mL/min, adjustments to the dosing regimen are required [see Dosage and Administration (2.3)].

Table 1: Dosage in Adult Patients with Normal Renal Function (creatinine clearance ≥ 50 mL/min)
Type of Infection* Dosed Every 24 hours Duration (days)
*
Due to the designated pathogens [see Indications and Usage (1)].
Sequential therapy (intravenous to oral) may be instituted at the discretion of the physician.
Due to methicillin-susceptible Staphylococcus aureus, Streptococcus pneumoniae (including multi-drug-resistant isolates [MDRSP]), Haemophilus influenzae, Haemophilus parainfluenzae, Klebsiella pneumoniae, Moraxella catarrhalis, Chlamydophila pneumoniae, Legionella pneumophila, or Mycoplasma pneumoniae [see Indications and Usage (1.2)].
§
Due to Streptococcus pneumoniae (excluding multi-drug-resistant isolates [MDRSP]), Haemophilus influenzae, Haemophilus parainfluenzae, Mycoplasma pneumoniae, or Chlamydophila pneumoniae [see Indications and Usage (1.3)].
Drug administration should begin as soon as possible after suspected or confirmed exposure to aerosolized B. anthracis. This indication is based on a surrogate endpoint. Levofloxacin plasma concentrations achieved in humans are reasonably likely to predict clinical benefit [see Clinical Studies (14.9)].
#
The safety of Levofloxacin in adults for durations of therapy beyond 28 days or in pediatric patients for durations beyond 14 days has not been studied. An increased incidence of musculoskeletal adverse events compared to controls has been observed in pediatric patients [see Warnings and Precautions (5.10), Use in Specific Populations (8.4), and Clinical Studies (14.9)]. Prolonged Levofloxacin therapy should only be used when the benefit outweighs the risk.
Þ
Drug administration should begin as soon as possible after suspected or confirmed exposure to Yersinia pestis. Higher doses of Levofloxacin typically used for treatment of pneumonia can be used for treatment of plague, if clinically indicated.
ß
This regimen is indicated for cUTI due to Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis and AP due to E. coli, including cases with concurrent bacteremia.
à
This regimen is indicated for cUTI due to Enterococcus faecalis, Enterococcus cloacae, Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, Pseudomonas aeruginosa; and for AP due to E. coli.

Dosage Adjustment in Adults with Renal Impairment

Administer Levofloxacin with caution in the presence of renal insufficiency. Careful clinical observation and appropriate laboratory studies should be performed prior to and during therapy since elimination of levofloxacin may be reduced.

No adjustment is necessary for patients with a creatinine clearance ≥ 50 mL/min.

In patients with impaired renal function (creatinine clearance <50 mL/min), adjustment of the dosage regimen is necessary to avoid the accumulation of levofloxacin due to decreased clearance [see Use in Specific Populations (8.6)].

Table 3 shows how to adjust dose based on creatinine clearance.

Table 3: Dosage Adjustment in Adult Patients with Renal Impairment (creatinine clearance <50 mL/min)
Dosage in Normal Renal Function Every 24 hours Creatinine Clearance
20 to 49 mL/min
Creatinine Clearance
10 to 19 mL/min
Hemodialysis or Chronic Ambulatory Peritoneal Dialysis (CAPD)
750 mg 750 mg every 48 hours 750 mg initial dose, then 500 mg every 48 hours 750 mg initial dose, then 500 mg every 48 hours
500 mg 500 mg initial dose, then 250 mg every 24 hours 500 mg initial dose, then 250 mg every 48 hours 500 mg initial dose, then 250 mg every 48 hours
250 mg No dosage adjustment required 250 mg every 48 hours. If treating uncomplicated UTI, then no dosage adjustment is required No information on dosing adjustment is available

Drug Interaction With Chelation Agents: Antacids, Sucralfate, Metal Cations, Multivitamins

Levofloxacin Oral Solution

Levofloxacin Oral Solution should be administered at least two hours before or two hours after antacids containing magnesium, aluminum, as well as sucralfate, metal cations such as iron, and multivitamin preparations with zinc or didanosine chewable/buffered tablets or the pediatric powder for oral solution [see Drug Interactions (7.1) and Patient Counseling Information (17.2)].

Administration Instructions

Food and Levofloxacin Oral Solution

It is recommended that Levofloxacin Oral Solution be taken 1 hour before or 2 hours after eating.

Hydration for Patients Receiving Levofloxacin Oral Solution

Adequate hydration of patients receiving oral Levofloxacin should be maintained to prevent the formation of highly concentrated urine. Crystalluria and cylindruria have been reported with quinolones [see Adverse Reactions (6.1) and Patient Counseling Information (17.2)].
