Generic Norfloxacin Information

Introduction

Norfloxacin is a synthetic fluoro‑quinolone antibiotic used to treat a variety of bacterial infections. In Hong Kong it is available as a prescription‑only medicine and is supplied by several international manufacturers. The active compound is Norfloxacin, classified under the antibiotic group. While its primary indication is for urinary‑tract, gastrointestinal and lower‑respiratory infections, clinicians also employ it for certain sexually transmitted infections and prophylaxis after exposure to contaminated water.

What is Norfloxacin?

• Generic definition – Norfloxacin is the generic version of the original brand Noroxin® (manufactured by Bayer) and other branded forms such as Norflox® and Norflurac®. All contain the identical active compound Norfloxacin.
• Classification – It belongs to the fluoro‑quinolone class of antibiotics, which target bacterial DNA replication.
• Development – First synthesized in the early 198s, Norfloxacin was introduced to the market to provide a broad‑spectrum option against Gram‑negative and some Gram‑positive organisms.
• Manufacturer – Various pharmaceutical companies produce generic Norfloxacin; in Hong Kong the product is often sourced from licensed overseas manufacturers that meet WHO‑GMP standards.

Norfloxacin is the generic version of Noroxin, containing the same active compound Norfloxacin. Our online pharmacy provides this generic alternative as a cost‑effective treatment option.

How Norfloxacin Works

Norfloxacin inhibits two essential bacterial enzymes: DNA gyrase (topoisomerase II) and topoisomerase IV. These enzymes are required for unwinding and resealing DNA during replication and transcription. By binding to the enzyme‑DNA complex, Norfloxacin prevents the re‑ligation step, leading to DNA breakage and bacterial cell death. The bactericidal effect appears within a few hours after absorption, with peak plasma concentrations reached in approximately 1–2 hours for oral tablets. The drug is primarily eliminated unchanged by the kidneys, giving a half‑life of 3–4 hours in healthy adults.

Conditions Treated with Norfloxacin

• Uncomplicated urinary‑tract infections (UTIs) – Escherichia coli, Proteus spp., and Klebsiella spp. are common pathogens in Hong Kong’s community‑acquired UTIs.
• Acute bacterial prostatitis – Penetrates prostatic tissue sufficiently to achieve therapeutic levels.
• Traveler’s diarrhea caused by Shigella, Campylobacter or Enterotoxigenic E. coli – Frequently encountered by residents and tourists returning from Southeast Asia.
• Lower respiratory tract infections – Mild to moderate exacerbations of chronic bronchitis caused by Haemophilus influenzae or Moraxella catarrhalis.
• Sexually transmitted infections – Used in combination regimens for chancroid and uncomplicated gonorrhea when resistance patterns permit.
• Prophylaxis after exposure to contaminated water – In outbreak settings, such as after natural disasters, Norfloxacin can be used for short‑term prophylaxis against bacterial gastroenteritis.

These indications are based on clinical trials and local antimicrobial‑susceptibility data published by the Hong Kong Centre for Health Protection (CHP).

Suitable Candidates for Norfloxacin Treatment

• Adults with confirmed or strongly suspected bacterial infections listed above, who have no contraindications to fluoro‑quinolones.
• Patients requiring a single‑daily oral regimen – the standard 400 mg tablet allows once‑daily dosing for many infections, improving adherence.
• Individuals with normal renal function – typical dosing applies; dose adjustment is required only for severe renal impairment (creatinine clearance <30 mL/min).
• Patients who cannot tolerate β‑lactam antibiotics – Norfloxacin offers an alternative when penicillin or cephalosporin allergies are present.

Contraindications / cautionary groups include:

• Pregnant or breastfeeding women (category C, limited data).
• Children and adolescents (risk of musculoskeletal toxicity).
• Patients with known hypersensitivity to fluoro‑quinolones.
• Individuals with a history of tendon disorders, especially those over 60 years or on systemic corticosteroids.

Risks, Side Effects, and Interactions

Common

• Nausea, vomiting, or abdominal discomfort.
• Headache or dizziness.
• Mild skin rash or pruritus.

Rare

• Photosensitivity reactions (increased sunburn risk).
• Transient elevation of liver enzymes.
• Mild QT‑interval prolongation on ECG.

Serious

• Tendon rupture or tendinopathy, especially of the Achilles tendon.
• Central nervous system effects such as seizures, hallucinations, or severe anxiety.
• Peripheral neuropathy, which may be irreversible.
• Severe allergic reactions (anaphylaxis, Stevens‑Johnson syndrome).

Important drug–drug interactions

• Antacids containing magnesium or aluminum – reduce oral absorption; administer at least 2 hours apart.
• Non‑steroidal anti‑inflammatory drugs (NSAIDs) – may increase risk of CNS toxicity.
• Warfarin – can enhance anticoagulant effect; monitor INR closely.
• Cytochrome P450‑interacting agents (e.g., theophylline, caffeine) – may raise plasma levels of Norfloxacin.
• Other fluoro‑quinolones – concurrent use is unnecessary and increases toxicity risk.

Patients should disclose all current medications, including over‑the‑counter supplements, to the prescribing clinician.

Practical Use: Dosing, Missed Dose, Overdose

• Standard adult dosing – 400 mg orally once daily for uncomplicated UTIs (3 days) or 400 mg twice daily for prostatitis or severe gastrointestinal infections (7–14 days).
• Administration – Swallow tablets whole with a full glass of water. Food does not significantly affect absorption, but high‑calcium meals may slightly reduce bioavailability; spacing the dose from dairy products is advisable.
• Missed dose – Take the missed tablet as soon as remembered unless it is close to the time of the next scheduled dose. Do not double‑dose.
• Overdose – Symptoms may include severe nausea, vomiting, dizziness, or seizures. Seek immediate medical attention; supportive care (activated charcoal, IV fluids) is the mainstay.
• Special precautions – Avoid excessive sunlight or tanning beds during therapy. Patients on corticosteroids or aged >60 years should be warned about tendon injury.

FAQ

• Is Norfloxacin available in both brand‑name and generic forms in Hong Kong?
  Yes. The original brand‑name product is marketed as Noroxin®, while multiple generic manufacturers provide Norfloxacin tablets containing the same active ingredient at lower cost.

• Does Norfloxacin require refrigeration or any special storage conditions?
  No. Norfloxacin tablets should be stored at room temperature, protected from moisture, direct sunlight, and heat. Keep the container tightly closed and out of reach of children.

• What does a Norfloxacin tablet look like, and how can I identify it?
  Generic tablets are usually round, 400 mg, and white or off‑white. Imprint codes vary by manufacturer; common markings include “400 MG” and a stylized “N”. Always verify the packaging and batch number against the supplier’s documentation.

• Can I travel with Norfloxacin on an international flight?
  Yes, provided the medication is in its original labeled container and you carry a copy of the prescription or a doctor’s note if required by customs. Keep it in carry‑on luggage to avoid temperature extremes in the cargo hold.

• How does Norfloxacin differ from newer fluoro‑quinolones like Levofloxacin?
  Norfloxacin has a narrower spectrum and lower potency against some Gram‑positive organisms compared with newer agents. However, it retains good activity against many urinary and gastrointestinal pathogens and is often less expensive.

• Is there any cross‑reactivity between Norfloxacin and other antibiotics for patients with allergies?
  Allergic reactions to Norfloxacin are rare and usually specific to fluoro‑quinolones. Cross‑reactivity with β‑lactams (penicillins, cephalosporins) is not typical. Patients with a known fluoro‑quinolone allergy should avoid Norfloxacin.

• What is the typical duration of therapy for uncomplicated urinary‑tract infection?
  A short course of 3 days (400 mg once daily) is generally sufficient for uncomplicated UTIs in adults, provided the pathogen is susceptible and symptoms resolve promptly.

• Can Norfloxacin affect laboratory drug testing?
  Fluoro‑quinolones are not commonly screened for in standard occupational drug tests. However, they may appear in specialized toxicology panels if specifically requested.

• Are there any known differences in formulation between Asian and Western markets?
  The active ingredient and dosage strength are identical worldwide, but excipients (binders, fillers) can differ. Some Asian formulations may use hypo‑allergenic fillers, which can be relevant for patients with specific sensitivities.
