Adjunctive therapy should be used as clinically indicated. Where Pseudomonas aeruginosa is a documented or presumptive pathogen, combination therapy with an anti-pseudomonal β-lactam is recommended [see Clinical Studies (14.1)].
1.2Community-Acquired Pneumonia: 7 to 14 day Treatment Regimen Levofloxacin tablets are indicated in adult patients for the treatment of community-acquired pneumonia due to methicillin-susceptible Staphylococcus aureus, Streptococcus pneumoniae (including multi-drug-resistant Streptococcus pneumoniae [MDRSP]), Haemophilus influenzae, Haemophilus parainfluenzae, Klebsiella pneumoniae, Moraxella catarrhalis, Chlamydophila pneumoniae, Legionella pneumophila, or Mycoplasma pneumoniae [see Dosage and Administration (2.1) and Clinical Studies (14.2)].
MDRSP isolates are isolates resistant to two or more of the following antibacterials: penicillin (MIC ≥2 mcg/mL), 2nd generation cephalosporins, e.g., cefuroxime, macrolides, tetracyclines and trimethoprim/sulfamethoxazole.
1.3Community-Acquired Pneumonia: 5-day Treatment Regimen Levofloxacin tablets are indicated in adult patients for the treatment of community-acquired pneumonia due to Streptococcus pneumoniae (excluding multi-drug-resistant isolates [MDRSP]), Haemophilus influenzae, Haemophilus parainfluenzae, Mycoplasma pneumoniae, or Chlamydophila pneumoniae [see Dosage and Administration (2.1) and Clinical Studies (14.3)].
1.4Complicated Skin and Skin Structure Infections Levofloxacin tablets are indicated in adult patients for the treatment of complicated skin and skin structure infections due to methicillin-susceptible Staphylococcus aureus, Enterococcus faecalis, Streptococcus pyogenes, or Proteus mirabilis [see Clinical Studies (14.5)].
1.5Uncomplicated Skin and Skin Structure Infections Levofloxacin tablets are indicated in adult patients for the treatment of uncomplicated skin and skin structure infections (mild to moderate) including abscesses, cellulitis, furuncles, impetigo, pyoderma, wound infections, due to methicillin-susceptible Staphylococcus aureus, or Streptococcus pyogenes.
1.6Chronic Bacterial Prostatitis Levofloxacin tablets are indicated in adult patients for the treatment of chronic bacterial prostatitis due to Escherichia coli, Enterococcus faecalis, or methicillin-susceptible Staphylococcus epidermidis [see Clinical Studies (14.6)].
1.7Inhalational Anthrax (Post-Exposure) Levofloxacin tablets are indicated for inhalational anthrax (post-exposure) to reduce the incidence or progression of disease following exposure to aerosolized Bacillus anthracis in adults and pediatric patients, 6 months of age and older [see Dosage and Administration (2.2)].The effectiveness of levofloxacin tablets is based on plasma concentrations achieved in humans, a surrogate endpoint reasonably likely to predict clinical benefit. Levofloxacin tablets have not been tested in humans for the post-exposure prevention of inhalation anthrax.
The safety of levofloxacin tablets in adults for durations of therapy beyond 28 days or in pediatric patients for durations of therapy beyond 14 days has not been studied. Prolonged levofloxacin tablets therapy should only be used when the benefit outweighs the risk [see Clinical Studies (14.9)].

⚠️ Warnings and Cautions ▾
5.1Disabling and Potentially Irreversible Serious Adverse Reactions Including Tendinitis and Tendon Rupture, Peripheral Neuropathy, and Central Nervous System Effects Fluoroquinolones, including levofloxacin, have been associated with disabling and potentially irreversible serious adverse reactions from different body systems that can occur together in the same patient. Commonly seen adverse reactions include tendinitis, tendon rupture, arthralgia, myalgia, peripheral neuropathy, and central nervous system effects (hallucinations, anxiety, depression, insomnia, severe headaches, and confusion).
These reactions can occur within hours to weeks after starting levofloxacin. Patients of any age or without pre-existing risk factors have experienced these adverse reactions [see Warnings and Precautions (5.2, 5.3, 5.4)]. Discontinue levofloxacin immediately at the first signs or symptoms of any serious adverse reaction.
In addition, avoid the use of fluoroquinolones, including levofloxacin, in patients who have experienced any of these serious adverse reactions associated with fluoroquinolones.
5.2Tendinopathy and Tendon Rupture Fluoroquinolones, including levofloxacin, have been associated with an increased risk of tendinitis and tendon rupture in all ages [see Warnings and Precautions (5.1)and Adverse Reactions (6.2)].This adverse reaction most frequently involves the Achilles tendon and has also been reported with the rotator cuff (the shoulder), the hand, the biceps, the thumb, and other tendon sites. Tendinitis or tendon rupture can occur within hours or days of starting levofloxacin or as long as several months after completion of fluoroquinolone therapy.
Tendinitis and tendon rupture can occur bilaterally. The risk of developing fluoroquinolone-associated tendinitis and tendon rupture is increased in patients over 60 years of age, in those taking corticosteroid drugs, and in patients with kidney, heart or lung transplants. Other factors that may independently increase the risk of tendon rupture include strenuous physical activity, renal failure, and previous tendon disorders such as rheumatoid arthritis.
Tendinitis and tendon rupture have been reported in patients taking fluoroquinolones who do not have the above risk factors. Discontinue levofloxacin immediately if the patient experiences pain, swelling, inflammation or rupture of a tendon. Patients should be advised to rest at the first sign of tendinitis or tendon rupture, and to contact their healthcare provider regarding changing to a non-quinolone antimicrobial drug.
Avoid levofloxacin in patients who have a history of tendon disorders or tendon rupture [see Adverse Reactions (6.3) and Patient Counseling Information (17)].
5.3Peripheral Neuropathy Fluoroquinolones, including levofloxacin, have been associated with an increased risk of peripheral neuropathy. Cases of sensory or sensorimotor axonal polyneuropathy affecting small and/or large axons resulting in paresthesias, hypoesthesias, dysesthesias and weakness have been reported in patients receiving fluoroquinolones, including levofloxacin. Symptoms may occur soon after initiation of levofloxacin and may be irreversible in some patients [see Warnings and Precautions (5.1)and Adverse Reactions (6.1,6.2)].
Discontinue levofloxacin immediately if the patient experiences symptoms of neuropathy including pain, burning, tingling, numbness, and/or weakness or other alterations of sensation including light touch, pain, temperature, position sense, and vibratory sensation. Avoid fluoroquinolones, including levofloxacin, in patients who have previously experienced peripheral neuropathy [see Adverse Reactions (6) and Patient Counseling Information (17)].
5.4Central Nervous System Effects Psychiatric Adverse ReactionsFluoroquinolones, including levofloxacin, have been associated with an increased risk of psychiatric adverse reactions, including: toxic psychoses, hallucinations, or paranoia; depression, or suicidal thoughts; an…
🤒 Adverse Reactions ▾
6.1Serious and Otherwise Important Adverse Reactions The following serious and otherwise important adverse drug reactions are discussed in greater detail in other sections of labeling: • Disabling and Potentially Irreversible Serious Adverse Reactions [see Warnings and Precautions(5.1)] • Tendinitis and Tendon Rupture [see Warnings and Precautions (5.2)] • Peripheral Neuropathy [see Warnings and Precautions (5.3)] • Central Nervous System Effects [see Warnings and Precautions (5.4)] • Exacerbation of Myasthenia Gravis [see Warnings and Precautions (5.5)] • Other Serious and Sometimes Fatal Reactions [see Warnings and Precautions (5.6)] • Hypersensitivity Reactions [see Warnings and Precautions (5.7)] • Hepatotoxicity [see Warnings and Precautions (5.8)] • Risk of Aortic Aneurysm and Dissection [see Warnings and Precautions (5.9)] • Clostridium difficile-Associated Diarrhea [see Warnings and Precautions (5.10)] • Prolongation of the QT Interval [see Warnings and Precautions (5.11)] • Musculoskeletal Disorders in Pediatric Patients [see Warnings and Precautions (5.12)] • Blood Glucose Disturbances [see Warnings and Precautions (5.13)] • Photosensitivity/Phototoxicity [see Warnings and Precautions (5.14)] • Development of Drug Resistant Bacteria [see Warnings and Precautions (5.15)] Crystalluria and cylindruria have been reported with quinolones, including levofloxacin.
Therefore, adequate hydration of patients receiving levofloxacin should be maintained to prevent the formation of a highly concentrated urine [see Dosage and Administration (2.5)].
6.2Clinical Trial Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The data described below reflect exposure to levofloxacin in 7537 patients in 29 pooled Phase 3 clinical trials. The population studied had a mean age of 50 years (approximately 74% of the population was < 65 years of age), 50% were male, 71% were Caucasian, 19% were Black.
Patients were treated with levofloxacin for a wide variety of infectious diseases [see Indications and Usage (1)].Patients received levofloxacin doses of 750 mg once daily, 250 mg once daily, or 500 mg once or twice daily. Treatment duration was usually 3 to 14 days, and the mean number of days on therapy was 10 days. The overall incidence, type and distribution of adverse reactions was similar in patients receiving levofloxacin doses of 750 mg once daily, 250 mg once daily, and 500 mg once or twice daily.
Discontinuation of levofloxacin due to adverse drug reactions occurred in 4.3% of patients overall, 3.8% of patients treated with the 250 mg and 500 mg doses and 5.4% of patients treated with the 750 mg dose. The most common adverse drug reactions leading to discontinuation with the 250 and 500 mg doses were gastrointestinal (1.4%), primarily nausea (0.6%); vomiting (0.4%); dizziness (0.3%); and headache (0.2%). The most common adverse drug reactions leading to discontinuation with the 750 mg dose were gastrointestinal (1.2%), primarily nausea (0.6%), vomiting (0.5%); dizziness (0.3%); and headache (0.3%).
Adverse reactions occurring in ≥1% of levofloxacin-treated patients and less common adverse reactions, occurring in 0.1 to <1% of levofloxacin-treated patients, are shown in Table 4 and Table 5, respectively. The most common adverse drug reactions (≥3%) are nausea, headache, diarrhea, insomnia, constipation, and dizziness.

🔄 Drug Interactions ▾
7.1Chelation Agents: Antacids, Sucralfate, Metal Cations, Multivitamins While the chelation by divalent cations is less marked than with other fluoroquinolones, concurrent administration of levofloxacin tablets with antacids containing magnesium, or aluminum, as well as sucralfate, metal cations such as iron, and multivitamin preparations with zinc may interfere with the gastrointestinal absorption of levofloxacin, resulting in systemic levels considerably lower than desired. Tablets with antacids containing magnesium, aluminum, as well as sucralfate, metal cations such as iron, and multivitamin preparations with zinc or didanosine may substantially interfere with the gastrointestinal absorption of levofloxacin, resulting in systemic levels considerably lower than desired.
These agents should be taken at least two hours before or two hours after oral levofloxacin administration.
7.2Warfarin No significant effect of levofloxacin on the peak plasma concentrations, AUC, and other disposition parameters for R- and S- warfarin was detected in a clinical study involving healthy volunteers. Similarly, no apparent effect of warfarin on levofloxacin absorption and disposition was observed. However, there have been reports during the postmarketing experience in patients that levofloxacin enhances the effects of warfarin.
Elevations of the prothrombin time in the setting of concurrent warfarin and levofloxacin use have been associated with episodes of bleeding. Prothrombin time, International Normalized Ratio (INR), or other suitable anticoagulation tests should be closely monitored if levofloxacin is administered concomitantly with warfarin. Patients should also be monitored for evidence of bleeding [see Adverse Reactions (6.3) and Patient Counseling Information (17)].
7.3Antidiabetic Agents Disturbances of blood glucose, including hyperglycemia and hypoglycemia, have been reported in patients treated concomitantly with fluoroquinolones and an antidiabetic agent. Therefore, careful monitoring of blood glucose is recommended when these agents are co-administered [see Warnings and Precautions (5.13), Adverse Reactions (6.2),and Patient Counseling Information (17)].
7.4Non-Steroidal Anti-Inflammatory Drugs The concomitant administration of a non-steroidal anti-inflammatory drug with a fluoroquinolone, including levofloxacin, may increase the risk of CNS stimulation and convulsive seizures [see Warnings and Precautions (5.4)].
7.5Theophylline No significant effect of levofloxacin on the plasma concentrations, AUC, and other disposition parameters for theophylline was detected in a clinical study involving healthy volunteers. Similarly, no apparent effect of theophylline on levofloxacin absorption and disposition was observed. However, concomitant administration of other fluoroquinolones with theophylline has resulted in prolonged elimination half-life, elevated serum theophylline levels, and a subsequent increase in the risk of theophylline-related adverse reactions in the patient population.
Therefore, theophylline levels should be closely monitored and appropriate dosage adjustments made when levofloxacin is co-administered. Adverse reactions, including seizures, may occur with or without an elevation in serum theophylline levels [see Warnings and Precautions (5.4)].
7.6Cyclosporine No significant effect of levofloxacin on the peak plasma concentrations, AUC, and other disposition parameters for cyclosporine was detected in a clinical study involving healthy volunteers. However, elevated serum levels of cyclosporine have been reported in the patient population when co-administered with some other fluoroquinolones. Levofloxacin Cmax and ke were slightly lower while Tmax and t1/2 were slightly longer in the presence of cyclosporine than those observed in other studies without concomitant medication.
The differences, however, are not considered to be clinically significant. Therefore, no dosage adjustment is required for levofloxacin o…
👥 Use in Specific Populations ▾
8.1Pregnancy Pregnancy Category C. Levofloxacin was not teratogenic in rats at doses as high as 810 mg/kg/day which corresponds to 9.4 times the highest recommended oral human dose based upon relative body surface area. The oral dose of 810 mg/kg/day to rats caused decreased fetal body weight and increased fetal mortality.
No teratogenicity was observed when rabbits were dosed orally as high as 50 mg/kg/day which corresponds to 1.1 times the highest recommended oral human dose based upon relative body surface area. There are, however, no adequate and well-controlled studies in pregnant women. Levofloxacin should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
8.3Nursing Mothers Based on data on other fluoroquinolones and very limited data on levofloxacin, it can be presumed that levofloxacin will be excreted in human milk. Because of the potential for serious adverse reactions from levofloxacin in nursing infants, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.
8.4Pediatric Use Quinolones, including levofloxacin, cause arthropathy and osteochondrosis in juvenile animals of several species. [see Warnings and Precautions (5.12) and Animal Toxicology and/or Pharmacology (13.2)]. Inhalational Anthrax (Post-Exposure) Levofloxacin is indicated in pediatric patients 6 months of age and older, for inhalational anthrax (post-exposure). The risk-benefit assessment indicates that administration of levofloxacin to pediatric patients is appropriate.
The safety of levofloxacin in pediatric patients treated for more than 14 days has not been studied [see Indications and Usage (1.7),Dosage and Administration (2.2) and Clinical Studies (14.9)]. Plague Levofloxacin is indicated in pediatric patients, 6 months of age and older, for treatment of plague, including pneumonic and septicemic plague due to Yersinia pestis (Y. pestis) and prophylaxis for plague. Efficacy studies of levofloxacin could not be conducted in humans with pneumonic plague for ethical and feasibility reasons.
Therefore, approval of this indication was based on an efficacy study conducted in animals. The risk-benefit assessment indicates that administration of levofloxacin to pediatric patients is appropriate [see Indications and Usage (1.8),Dosage and Administration (2.2)and Clinical Studies (14.10)]. Safety and effectiveness of levofloxacin in pediatric patients below the age of six months have not been established.
Pharmacokinetics following intravenous administration The pharmacokinetics of levofloxacin following a single intravenous dose were investigated in pediatric patients ranging in age from six months to 16 years. Pediatric patients cleared levofloxacin faster than adult patients resulting in lower plasma exposures than adults for a given mg/kg dose [see Clinical Pharmacology (12.3) and Clinical Studies (14.9)]. Dosage in Pediatric Patients with Inhalational Anthrax or Plague For the recommended levofloxacin tablet dosage in pediatric patients with inhalational anthrax or plague, see Dosage and Administration (2.2).
Levofloxacin Tablets cannot be administered to pediatric patients who weigh less than 30 kg because of the limitations of the available strengths. Alternative formulations of levofloxacin may be considered for pediatric patients who weigh less than 30 kg. Adverse Reactions In clinical trials, 1534 pediatric patients (6 months to 16 years of age) were treated with oral and intravenous levofloxacin.
Pediatric patients 6 months to 5 years of age received levofloxacin 10 mg/kg twice a day and pediatric patients greater than 5 years of age received 10 mg/kg once a day (maximum 500 mg per day) for approximately 10 days. Levofloxacin tablets can only be administered to pediatric patients with inhalational anthrax (post-exposure) or plague who are 30 kg or greater due to the limitations of the available strengths…
🆘 Overdosage ▾
In the event of an acute overdosage, the stomach should be emptied. The patient should be observed and appropriate hydration maintained. Levofloxacin is not efficiently removed by hemodialysis or peritoneal dialysis.
Levofloxacin exhibits a low potential for acute toxicity. Mice, rats, dogs and monkeys exhibited the following clinical signs after receiving a single high dose of levofloxacin: ataxia, ptosis, decreased locomotor activity, dyspnea, prostration, tremors, and convulsions. Doses in excess of 1500 mg/kg orally and 250 mg/kg IV produced significant mortality in rodents.

Levofloxacin pharmacokinetics are linear and predictable after single and multiple oral or IV dosing regimens.
Steady-state conditions are reached within 48 hours following a 500 mg or 750 mg once-daily dosage regimen. The mean ± SD peak and trough plasma concentrations attained following multiple once-daily oral dosage regimens were approximately 5.7 ± 1.4 and 0.5 ± 0.2 mcg/mL after the 500 mg doses, and 8.6 ± 1.9 and 1.1 ± 0.4 mcg/mL after the 750 mg doses, respectively. The mean ± SD peak and trough plasma concentrations attained following multiple once-daily IV regimens were approximately 6.4 ± 0.8 and 0.6 ± 0.2 mcg/mL after the 500 mg doses, and 12.1 ± 4.1 and 1.3 ± 0.71 mcg/mL after the 750 mg doses, respectively.
Absorption Levofloxacin is rapidly and essentially completely absorbed after oral administration. Peak plasma concentrations are usually attained one to two hours after oral dosing. The absolute bioavailability of levofloxacin from a 500 mg tablet and a 750 mg tablet of levofloxacin are both approximately 99%, demonstrating complete oral absorption of levofloxacin.
Following a single intravenous dose of levofloxacin to healthy volunteers, the mean ± SD peak plasma concentration attained was 6.2 ± 1 mcg/mL after a 500 mg dose infused over 60 minutes and 11.5 ± 4 mcg/mL after a 750 mg dose infused over 90 minutes. Oral administration of a 500 mg dose levofloxacin with food prolongs the time to peak concentration by approximately 1 hour and decreases the peak concentration by approximately 14% following tablet and approximately 25% following oral solution administration. Therefore, levofloxacin tablets can be administered without regard to food.
The plasma concentration profile of levofloxacin after IV administration is similar and comparable in extent of exposure (AUC) to that observed for levofloxacin tab…

Levofloxacin (LEE-voe-FLOX-a-sin) Tablets USP What is the most important information I should know about levofloxacin tablets? Levofloxacin tablets, a fluoroquinolone antibiotic, can cause serious side effects. Some of these serious side effects can happen at the same time and could result in death.
If you have any of the following serious side effects while you take levofloxacin tablets, you should stop taking levofloxacin tablets immediately and get medical help right away. 1. Tendon rupture or swelling of the tendon (tendinitis). • Tendon problems can happen in people of all ages who take levofloxacin tablets.
Tendons are tough cords of tissue that connect muscles to bones. Some tendon problems include: o pain o swelling o tears and swelling of tendons including the back of the ankle (Achilles), shoulder, hand, or other tendon sites. • The risk of getting tendon problems while you take levofloxacin tablets is higher if you: o are over 60 years of age o are taking steroids (corticosteroids) o have had a kidney, heart or lung transplant. • Tendon problems can happen in people who do not have the above risk factors when they take levofloxacin tablets. • Other reasons that can increase your risk of tendon problems can include: o physical activity or exercise o kidney failure o tendon problems in the past, such as in people with rheumatoid arthritis (RA) • Stop taking levofloxacin tablets immediately and get medical help right away at the first sign of tendon pain, swelling or inflammation.
Avoid exercise and using the affected area. • The most common area of pain and swelling is the Achilles tendon at the back of your ankle. This can also happen with other tendons. You may need a different antibiotic that is not a fluoroquinolone to treat your infection. • Tendon rupture can happen while you are taking or after you have finished taking levofloxacin tablets.
Tendon ruptures can happen within hours or days of taking levofloxacin tablets and have happened up to several months after people have finished taking their fluoroquinolone. • Stop taking levofloxacin tablets immediately and get medical help right away if you get any of the following signs or symptoms of a tendon rupture: o hear or feel a snap or pop in a tendon area o bruising right after an injury in a tendon area o unable to move the affected area or bear weight 2. Changes in sensation and possible nerve damage (Peripheral Neuropathy).
Damage to the nerves in arms, hands, legs, or feet can happen in people who take fluoroquinolones, including levofloxacin tablets. Stop taking levofloxacin tablets immediately and talk to your healthcare provider right away if you get any of the following symptoms of peripheral neuropathy in your arms, hands, legs, or feet: • pain • numbness • burning • weakness • tingling The nerve damage may be permanent. 3.
Central Nervous System (CNS) effects. Seizures have been reported in people who take fluoroquinolone antibacterial medicines, including levofloxacin tablets. Tell your healthcare provider if you have a history of seizures before you start taking levofloxacin tablets.
CNS side effects may happen as soon as after taking the first dose of levofloxacin tablets. Stop taking levofloxacin tablets immediately and talk to your healthcare provider right away if you get any of these side effects, or other changes in mood or behavior: • seizures • trouble sleeping • hear voices, see things, or sense things that are not there (hallucinations) • nightmares • feel restless • feel lightheaded or dizzy • tremors • feel more suspicious (paranoia) • feel anxious or nervous • suicidal thoughts or acts • confusion • headaches that will not go away, with or without blurred vision • depression 4.
