Oftaquix (Levofloxacin Hemihydrate)

Oftaquix is a fluoroquinolone antibiotic that targets bacterial infections in several organ systems.

• Community‑acquired pneumonia: helps eradicate the causative bacteria and improve respiratory function.
• Acute bacterial sinusitis: reduces sinus inflammation by eliminating the infecting organisms.
• Uncomplicated urinary tract infection: clears the urinary pathogen and relieves urinary symptoms.
• Skin and soft‑tissue infections: combats susceptible Gram‑negative and Gram‑positive bacteria to promote healing.
• Chronic bronchitis exacerbations: assists in controlling bacterial overgrowth during flare‑ups.

• Levofloxacin inhibits bacterial DNA gyrase and topoisomerase IV, enzymes essential for DNA replication, transcription and repair. By blocking these enzymes, the drug prevents bacterial cells from proliferating and leads to cell death, providing a bactericidal effect against a broad spectrum of Gram‑negative and Gram‑positive organisms.

Levofloxacin, like other fluoroquinolones, may cause a range of adverse reactions.

Common Side Effects

• Nausea and vomiting: mild to moderate gastrointestinal upset.
• Diarrhea: loose stools that may be self‑limiting.
• Headache: transient cranial discomfort.
• Dizziness: occasional light‑headedness.
• Photosensitivity: increased skin sensitivity to sunlight.

Serious or Rare Side Effects

• Tendon rupture: sudden pain or loss of function in tendons, especially the Achilles.
• QT interval prolongation: irregular heart rhythm detectable on ECG.
• Severe hypersensitivity: rash, itching, swelling, or anaphylaxis.
• Peripheral neuropathy: tingling, numbness, or weakness in extremities.
• Clostridioides difficile infection: severe diarrhea due to bacterial overgrowth.

When using Levofloxacin, certain precautions should be observed to minimize risks.

• Assess renal function: dose adjustment may be required in impaired kidney function.
• Avoid concurrent use with antacids containing aluminum or magnesium: may reduce absorption.
• Monitor for tendon pain: discontinue if signs of tendon inflammation appear.
• Caution in patients with cardiac arrhythmias: may prolong QT interval.
• Use with caution in pregnant or breastfeeding women: only if clearly needed.
• Store at below 25°C: keep in the original packaging, protect from moisture and direct sunlight.

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

Major Interactions (Avoid)

• Antacids/aluminum‑magnesium: reduce levofloxacin absorption.
• Warfarin: may increase anticoagulant effect and bleeding risk.
• Theophylline: heightened risk of seizures.

Moderate Interactions (Monitor Closely)

• NSAIDs: may increase risk of central nervous system stimulation.
• Diabetic agents: potential for altered blood glucose control.
• Corticosteroids: may raise the chance of tendon injury.
