Levofloxacin Ipca Laboratories Uk (Levofloxacin)

• Levofloxacin is a broad‑spectrum fluoroquinolone antibiotic used to treat bacterial infections in several organ systems.
• Community‑acquired pneumonia: effective eradication of susceptible respiratory pathogens.
• Acute bacterial sinusitis: rapid resolution of sinus inflammation caused by bacteria.
• Acute exacerbations of chronic bronchitis: reduces bacterial load and improves airflow.
• Urinary tract infections: clears common uropathogens in uncomplicated cases.
• Skin and soft‑tissue infections: treats cellulitis and wound infections caused by susceptible organisms.

• Levofloxacin inhibits bacterial DNA gyrase and topoisomerase IV, enzymes essential for DNA replication, transcription, and repair. By binding to these enzymes, it prevents the unwinding of DNA, leading to inhibition of bacterial cell division and ultimately bacterial cell death. The drug exhibits concentration‑dependent bactericidal activity against a wide range of Gram‑positive and Gram‑negative organisms.

Levofloxacin may cause a variety of adverse reactions, ranging from mild to severe.

Common Side Effects

• Nausea or vomiting
• Diarrhea or loose stools
• Headache
• Dizziness or light‑headedness
• Insomnia or sleep disturbances
• Abdominal discomfort or pain

Serious or Rare Side Effects

• Tendon rupture or tendinitis, especially in the Achilles tendon
• QT interval prolongation leading to cardiac arrhythmias
• Severe allergic reactions such as Stevens‑Johnson syndrome
• Clostridioides difficile‑associated colitis
• Hepatotoxicity with elevated liver enzymes
• Peripheral neuropathy presenting as tingling or numbness

• Before prescribing Levofloxacin, clinicians should evaluate patient‑specific risk factors and monitor for potential complications.
• Assess renal function: adjust dosing in patients with impaired clearance.
• Review cardiac history: avoid in patients with known QT prolongation.
• Avoid in patients with a history of tendon disorders: increased risk of tendon rupture.
• Monitor for signs of hypersensitivity: discontinue if severe rash or anaphylaxis occurs.
• Store at ambient temperature: keep in original container, protect from moisture and direct sunlight.

Levofloxacin can interact with several medicines, altering efficacy or safety.

Major Interactions (Avoid)

• Antacids containing magnesium or aluminum: markedly reduce levofloxacin absorption.
• Warfarin: may increase anticoagulant effect and bleeding risk.
• Other QT‑prolonging agents: additive risk of cardiac arrhythmias.

Moderate Interactions (Monitor Closely)

• Nonsteroidal anti‑inflammatory drugs (NSAIDs): may increase central nervous system side effects.
• Theophylline: levofloxacin can raise plasma theophylline concentrations.
• Cyclosporine: may lead to higher cyclosporine levels and nephrotoxicity.
