Levofloxacin Kabi (Levofloxacin Hemihydrate)

• Levofloxacin Kabi is a fluoroquinolone antibiotic used to treat infections caused by susceptible bacteria.
• Community‑acquired pneumonia: achieves bacterial eradication and clinical improvement.
• Complicated urinary tract infections: resolves infection and prevents recurrence.
• Complicated intra‑abdominal infections: clears intra‑abdominal pathogens.
• Skin and soft tissue infections: reduces infection signs and promotes healing.
• Acute bacterial sinusitis: eliminates sinus pathogens and relieves symptoms.

• Levofloxacin binds to bacterial DNA gyrase (topoisomerase II) and topoisomerase IV, enzymes required for DNA supercoiling, replication and transcription. By stabilizing the enzyme‑DNA complex, it prevents DNA unwinding, leading to inhibition of bacterial replication and ultimately bactericidal cell death across a broad spectrum of Gram‑negative and Gram‑positive organisms.

Levofloxacin Kabi may be associated with a range of adverse reactions, varying from mild to severe.

Common Side Effects

• Nausea: mild gastrointestinal upset.
• Diarrhea: loose stools, usually self‑limited.
• Headache: transient cranial discomfort.
• Rash: mild skin eruption.

Serious or Rare Side Effects

• Tendon rupture: risk of tendonitis or rupture, especially in older adults.
• QT prolongation: potential for cardiac arrhythmia.
• Clostridioides difficile colitis: severe intestinal infection.
• Severe hypersensitivity reactions: anaphylaxis, Stevens‑Johnson syndrome.

• When using Levofloxacin Kabi, clinicians should consider several safety precautions to minimize risks.
• Renal impairment: adjust dosing in patients with reduced kidney function.
• Hepatic impairment: monitor liver function tests.
• Concomitant QT‑prolonging drugs: avoid or monitor cardiac rhythm.
• History of tendon disorders: avoid use in patients with prior tendon injury.
• Pregnancy and lactation: use only if benefits outweigh risks (category unknown).
• Store at 2-8°C: keep refrigerated, protect from light, do not freeze or shake.

Levofloxacin Kabi can interact with other medicines, affecting its efficacy or safety.

Major Interactions (Avoid)

• Antacids containing aluminum or magnesium: reduce levofloxacin absorption.
• Warfarin: may increase anticoagulant effect.
• Theophylline: may raise plasma concentrations.
• Cyclosporine: increased risk of nephrotoxicity.

Moderate Interactions (Monitor Closely)

• NSAIDs: may increase risk of CNS stimulation.
• Diabetic agents (insulin, sulfonylureas): may cause hypoglycemia.
• Corticosteroids: heightened risk of tendon rupture.
• Oral contraceptives: possible reduction in effectiveness.
