Levofloxacin Ratiopharm (Levofloxacin Hemihydrate)

Levofloxacin is a fluoroquinolone antibiotic used to treat bacterial infections in various organ systems.

• Urinary tract infections: eradicates the causative bacteria, relieving symptoms and preventing recurrence.
• Respiratory tract infections: combats pathogens causing pneumonia, bronchitis and sinusitis, improving breathing and reducing fever.
• Skin and soft tissue infections: eliminates bacterial involvement in cellulitis, abscesses and wound infections, promoting healing.
• Prostatitis: targets the infecting organisms in chronic bacterial prostatitis, aiding symptom resolution.

• Levofloxacin inhibits bacterial DNA gyrase (topoisomerase II) and topoisomerase IV, enzymes essential for DNA replication, transcription and repair. By binding to the quinolone‑binding site of these enzymes, it prevents the supercoiling and separation of DNA strands, leading to bacterial cell death. This bactericidal action is broad‑spectrum, affecting both Gram‑negative and Gram‑positive organisms.

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

Common Side Effects

• Nausea: mild stomach upset often occurring after the dose.
• Diarrhea: loose stools that may be self‑limiting.
• Headache: transient cranial discomfort.
• Dizziness: sensation of light‑headedness.
• Abdominal pain: cramp‑like discomfort in the stomach area.
• Rash: mild skin redness or itching.

Serious or Rare Side Effects

• Tendon rupture: sudden tendon pain or rupture, especially in the Achilles.
• QT interval prolongation: heart rhythm disturbances that may cause palpitations.
• Severe allergic reactions: anaphylaxis, swelling of face or throat.
• Clostridioides difficile infection: severe colitis with watery diarrhea.
• Hepatic toxicity: elevated liver enzymes or jaundice.
• Peripheral neuropathy: numbness or tingling in extremities.

Before prescribing Levofloxacin, clinicians should consider several safety precautions.

• Renal function assessment: adjust dose in patients with impaired kidney function.
• Hypersensitivity screening: avoid use in individuals with known allergy to fluoroquinolones.
• Tendon health monitoring: discontinue if tendon pain, swelling or inflammation occurs.
• Elderly caution: increased risk of CNS effects and tendon injury in older adults.
• QT prolongation risk: evaluate cardiac history and avoid concomitant QT‑prolonging drugs.
• Store at room temperature: keep in the original container, protect from moisture and heat.

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

Major Interactions (Avoid)

• Antacids containing aluminum or magnesium: reduce levofloxacin absorption; separate dosing by at least 2 hours.
• Warfarin: may increase INR and bleeding risk; monitor coagulation parameters closely.
• Theophylline: elevated plasma levels can cause toxicity; consider dose reduction.

Moderate Interactions (Monitor Closely)

• Corticosteroids: combined use raises risk of tendon rupture; monitor for musculoskeletal pain.
• Oral contraceptives: effectiveness may be reduced; advise additional non‑hormonal contraception.
