Monoflocet (Ofloxacin)

Ofloxacin is a broad‑spectrum fluoroquinolone antibiotic used to treat infections caused by susceptible bacteria.

• Urinary tract infection: eliminates Gram‑negative pathogens, relieving dysuria and systemic symptoms.
• Acute bacterial sinusitis: reduces bacterial load, improving nasal congestion and facial pain.
• Skin and soft‑tissue infection: eradicates causative organisms, promoting wound healing.
• Community‑acquired pneumonia: combats respiratory pathogens, aiding recovery of lung function.

• Ofloxacin 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 the unwinding and resealing of DNA strands, halting bacterial DNA synthesis and leading to cell death. This dual targeting provides potent, concentration‑dependent bactericidal effects against a wide range of Gram‑negative and Gram‑positive organisms.

Ofloxacin may cause a variety of adverse reactions, ranging from mild to severe.

Common Side Effects

• Nausea: mild stomach upset occurring in many patients.
• Diarrhea: loose stools that are usually self‑limiting.
• Headache: transient cranial discomfort.
• Dizziness: light‑headed sensation.
• Abdominal pain: crampy 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: cardiac rhythm disturbance that may lead to arrhythmia.
• Severe allergic reaction: anaphylaxis with swelling, breathing difficulty.
• Clostridioides difficile colitis: severe diarrhea due to intestinal flora disruption.
• Hepatic toxicity: elevated liver enzymes or jaundice.
• Peripheral neuropathy: numbness or tingling in extremities.

When prescribing Ofloxacin, clinicians should consider several precautionary measures to minimize risk.

• Renal impairment: assess kidney function and adjust dose if necessary.
• History of tendon disorders: avoid use in patients with prior tendon injury or tendonitis.
• Concomitant QT‑prolonging agents: monitor cardiac rhythm closely.
• Pregnancy and lactation: reserve for situations where benefits outweigh potential risks.
• Age over 60 years: increased susceptibility to adverse events, use with caution.
• Store at ambient temperature: keep below 25 °C in the original packaging, protect from moisture and light.

Ofloxacin can interact with other medicines, affecting its efficacy or safety.

Major Interactions (Avoid)

• Antacids with magnesium/aluminum: markedly decrease Ofloxacin absorption.
• Warfarin: may increase anticoagulant effect and INR.
• Theophylline: elevated levels can cause toxicity.

Moderate Interactions (Monitor Closely)

• NSAIDs: may heighten CNS adverse effects.
• Oral contraceptives: possible reduced efficacy.
• Diabetes medications: may affect blood glucose control.
