Levofloxacina Teva (Levofloxacin Hemihydrate)

Levofloxacin is indicated for several bacterial infections affecting various organ systems.

• Community‑acquired respiratory tract infections: eradicates causative bacteria to resolve symptoms such as cough and fever.
• Acute bacterial sinusitis: eliminates sinus pathogens, reducing congestion and facial pain.
• Acute exacerbations of chronic bronchitis: treats bacterial flare‑ups, improving airflow and sputum production.
• Urinary tract infections (including complicated UTIs): clears urinary pathogens, relieving dysuria and frequency.
• Skin and soft‑tissue infections: combats bacterial invasion of skin, promoting healing and preventing spread.

• Levofloxacin exerts its antibacterial activity by binding to bacterial DNA gyrase (topoisomerase II) and topoisomerase IV, enzymes essential for DNA supercoiling and replication. Inhibition of these enzymes prevents DNA synthesis and transcription, leading to bacterial cell death. The drug displays concentration‑dependent killing and a post‑antibiotic effect against a broad range of Gram‑negative and Gram‑positive organisms.

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

Common Side Effects

• Nausea: mild stomach upset or queasiness.
• Diarrhea: loose stools, sometimes watery.
• Headache: transient cranial discomfort.
• Dizziness: sensation of light‑headedness or imbalance.

Serious or Rare Side Effects

• Tendon rupture or inflammation: sudden pain, swelling, or loss of function in tendons, especially the Achilles.
• QT interval prolongation: cardiac rhythm disturbances that may cause palpitations or fainting.
• Severe hypersensitivity reactions: rash, fever, facial swelling, or anaphylaxis requiring immediate medical attention.

Before prescribing Levofloxacina Teva, clinicians should consider several safety precautions.

• Renal impairment: adjust dose or monitor renal function closely.
• History of tendon disorders: avoid use in patients with prior tendon injury or those on corticosteroids.
• Cardiac arrhythmias: caution in patients with known QT prolongation or electrolyte imbalance.
• Central nervous system effects: monitor for seizures or confusion, especially in the elderly.
• Pregnancy and lactation: use only if benefits outweigh potential risks; limited data available.
• Store at ambient temperature: keep below 25 °C, in the original container, protected from moisture and light.

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

Major Interactions (Avoid)

• Antacids containing aluminum or magnesium: reduce levofloxacin absorption; separate administration by at least 2 hours.
• Non‑steroidal anti‑inflammatory drugs (NSAIDs): increase risk of central nervous system stimulation and seizures.
• Cytochrome P450 1A2 inhibitors (e.g., ciprofloxacin, fluvoxamine): raise levofloxacin plasma levels, heightening toxicity risk.

Moderate Interactions (Monitor Closely)

• Warfarin: may enhance anticoagulant effect; monitor INR closely.
• Theophylline: levofloxacin can increase serum theophylline concentrations; observe for toxicity signs.
