Norfloxa (Norfloxacin)

Norfloxacin, the active ingredient in Norfloxa, is a fluoroquinolone antibiotic presented as an oral tablet for oral use. It is indicated for infections caused by susceptible Gram‑negative and some Gram‑positive bacteria, offering a broad spectrum of antibacterial activity. It is employed to treat urinary tract infections, prostatitis and gonorrhea in adult patients.

GNH USA supplies Norfloxa as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide. The company adheres to stringent quality standards and provides regulatory documentation to support global distribution.

Norfloxacin is used to treat bacterial infections within the urinary and genitourinary systems, where it targets susceptible organisms. - Urinary tract infection: eradicates susceptible uropathogens, relieving dysuria, urgency, frequency, and preventing recurrence of infection. - Acute bacterial prostatitis: eliminates infection within prostate tissue, improving pelvic pain, urinary flow, and reducing systemic fever and malaise. - Gonorrhea: clears Neisseria gonorrhoeae infection of the urethra and cervix, reducing genital discharge, preventing complications such as pelvic inflammatory disease and limiting transmission.

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

Common Side Effects: - Nausea: mild stomach upset, often transient and self‑limiting. - Diarrhea: loose or watery stools, may be accompanied by abdominal cramping. - Headache: mild to moderate intensity, usually resolves without treatment. - Dizziness: sensation of lightheadedness or vertigo, may improve with rest. - Rash: mild skin erythema or itching, occasionally developing into a maculopapular eruption.

Serious or Rare Side Effects: - Tendon rupture: sudden tendon pain and loss of function, most commonly affecting the Achilles tendon, requiring immediate medical attention. - QT prolongation: prolongation of the cardiac QT interval that can lead to potentially life‑threatening arrhythmias. - Severe allergic reaction: anaphylaxis presenting with swelling, hives, breathing difficulty and hypotension. - Central nervous system effects: seizures, confusion or hallucinations, especially in patients with renal impairment. - Clostridioides difficile infection: severe colitis characterized by watery diarrhea, fever and abdominal pain.

When prescribing Norfloxacin, several precautions should be considered to minimize risks and ensure safe use. - Renal impairment: dose adjustment may be required; monitor kidney function. - Hepatic disease: use with caution; assess liver enzymes regularly. - Concomitant QT‑prolonging drugs: avoid combination to reduce risk of cardiac arrhythmias. - History of tendon disorders: avoid use in patients with prior tendon inflammation or rupture. - Pregnancy and breastfeeding: safety not established; use only if benefits outweigh risks. - Store at ambient temperature: keep below 25 °C, retain in original packaging, protect from moisture and light.

Norfloxacin can interact with other medicines, altering its effectiveness or increasing toxicity.

Major Interactions (Avoid): - Antacids containing aluminum or magnesium: reduce absorption of Norfloxacin; separate dosing by at least 2 hours. - Warfarin: may enhance anticoagulant effect, increasing bleeding risk; monitor INR closely. - Non‑steroidal anti‑inflammatory drugs (NSAIDs): increase risk of central nervous system stimulation and seizures.

Moderate Interactions (Monitor Closely): - Theophylline: may raise plasma levels, leading to toxicity; monitor symptoms. - Cyclosporine: increased risk of nephrotoxicity; assess renal function. - Corticosteroids: combined use may raise risk of tendon rupture; advise patient to report tendon pain.
