Levofloxacine Beximco (Levofloxacin)

Levofloxacin is a broad‑spectrum antibacterial that targets Gram‑negative and Gram‑positive organisms in several infection categories.

• Community‑acquired pneumonia: achieves bacterial eradication and clinical cure.
• Acute bacterial sinusitis: reduces symptom duration and prevents complications.
• Uncomplicated urinary tract infection: clears the causative pathogen and resolves urinary symptoms.
• Skin and skin‑structure infections: eliminates the infecting bacteria and promotes healing.

• Levofloxacin inhibits bacterial DNA gyrase (topoisomerase II) and topoisomerase IV, enzymes essential for DNA replication, transcription, and repair. By stabilizing the enzyme‑DNA complex, it prevents the resealing of DNA strands, leading to bacterial cell death and a bactericidal effect against susceptible organisms.

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

Common Side Effects

• Nausea: mild to moderate gastrointestinal upset.
• Diarrhea: loose stools, sometimes watery.
• Headache: transient cranial discomfort.
• Dizziness: sensation of light‑headedness.
• Insomnia: difficulty falling or staying asleep.
• Rash: mild skin erythema or pruritus.

Serious or Rare Side Effects

• Tendon rupture: especially Achilles tendon, often linked to sudden activity.
• QT interval prolongation: may predispose to cardiac arrhythmias.
• Clostridioides difficile infection: severe colitis with watery diarrhea.
• Severe allergic reactions: anaphylaxis, angioedema, or Stevens‑Johnson syndrome.
• Peripheral neuropathy: numbness or tingling in extremities.
• Hepatic toxicity: elevated liver enzymes or jaundice.

Levofloxacin requires careful assessment before prescribing to minimise risks.

• Assess renal function: adjust dosing in patients with impaired clearance.
• Avoid in patients with known tendon disorders: risk of tendon rupture is increased.
• Use caution in the elderly: higher incidence of CNS and musculoskeletal adverse events.
• Monitor cardiac status: watch for QT prolongation, especially with other QT‑affecting drugs.
• Limit concurrent NSAID use: may raise the chance of tendon injury.
• Store at room temperature: keep in the original container, protect from moisture and light.

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

Major Interactions (Avoid)

• Antacids containing aluminum or magnesium: reduce levofloxacin absorption.
• Warfarin: may increase anticoagulant effect and bleeding risk.
• Theophylline: levofloxacin can raise serum theophylline concentrations.

Moderate Interactions (Monitor Closely)

• Ciprofloxacin: additive risk of QT prolongation.
• NSAIDs: may increase central nervous system side effects.
• Glucocorticoids: combined use raises the chance of tendon rupture.
