Levofloxacin Vioser

Levofloxacin, the active ingredient in Levofloxacin Vioser, is a Fluoroquinolone antibiotic presented as an intravenous solution for injection use. It treats susceptible bacterial infections in adult patients when prescribed by a qualified healthcare professional.

GNH USA supplies Levofloxacin Vioser as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals worldwide.

Levofloxacin is a broad‑spectrum fluoroquinolone used for infections caused by susceptible bacteria.

- Community‑acquired pneumonia: eradicates the causative pathogens and improves respiratory function. - Urinary tract infection: clears bacterial colonisation of the urinary tract. - Skin and soft‑tissue infection: resolves cellulitis and related dermal infections. - Acute bacterial sinusitis: reduces sinus inflammation and bacterial load. - Chronic bronchitis exacerbation: shortens symptom duration and prevents complications.

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

Common Side Effects: - Nausea: mild to moderate stomach upset. - Diarrhoea: loose stools that may be self‑limiting. - Headache: transient cranial discomfort. - Dizziness: sensation of light‑headedness. - Rash: mild skin erythema. - Elevated liver enzymes: transient laboratory changes.

Serious or Rare Side Effects: - Tendon rupture: sudden pain and loss of function, especially in the Achilles tendon. - QT interval prolongation: risk of cardiac arrhythmias. - Clostridioides difficile infection: severe colitis requiring medical attention. - Severe allergic reactions: anaphylaxis, angioedema, or Stevens‑Johnson syndrome. - Hepatic dysfunction: jaundice or hepatitis. - Peripheral neuropathy: numbness or tingling in extremities.

Before initiating therapy, clinicians should evaluate patient‑specific risk factors and monitor for adverse events.

- Assess renal function: adjust dosing in impaired clearance. - Monitor for tendon pain: discontinue if signs of tendonitis appear. - Avoid in known hypersensitivity: do not use if allergic to fluoroquinolones. - Caution with QT‑prolonging conditions: evaluate cardiac risk. - Review concomitant medications: consider potential interactions. - Store at 2-8°C: keep refrigerated, protect from light, do not freeze.

Levofloxacin can alter the activity of several co‑administered drugs.

Major Interactions (Avoid): - Antacids containing magnesium or aluminum: reduce levofloxacin absorption. - Warfarin: may increase INR and bleeding risk. - Theophylline: can raise serum theophylline levels, leading to toxicity. - Cyclosporine: increased cyclosporine concentrations. - NSAIDs: heightened risk of central nervous system effects.

Moderate Interactions (Monitor Closely): - Oral contraceptives: may reduce contraceptive efficacy. - Diabetic agents: possible alteration of blood glucose control. - Corticosteroids: combined use raises tendon‑rupture risk. - Other QT‑prolonging drugs: additive cardiac effects. - Rifampin: may decrease levofloxacin plasma levels.
