What is Norfloxacin used for?
Norfloxacin is a fluoroquinolone antibiotic indicated for bacterial infections affecting several organ systems.
- Urinary tract infections: eradicates the causative bacteria, relieving symptoms and preventing recurrence. - Prostatitis: eliminates prostate‑resident pathogens, reducing inflammation and pain. - Gastrointestinal infections: clears enteric bacterial pathogens, restoring normal gut function. - Sexually transmitted infections (e.g., gonorrhea): targets Neisseria gonorrhoeae, achieving microbiological cure.
What are the side effects of Norfloxacin?
Norfloxacin may cause a range of adverse reactions, varying from mild to severe.
Common Side Effects: - Nausea: mild stomach upset occurring shortly after dosing. - Diarrhea: loose stools that may be self‑limiting. - Headache: transient cranial discomfort. - Rash: mild skin erythema or itching.
Serious or Rare Side Effects: - Tendon rupture: sudden tendon pain or swelling, especially in the Achilles. - QT prolongation: irregular heart rhythm that may cause palpitations. - Severe allergic reaction: swelling, breathing difficulty, or hives. - Clostridioides difficile infection: persistent watery diarrhea requiring medical attention.
What precautions apply to Norfloxacin?
When prescribing Norfloxacin, clinicians should observe several precautionary measures to minimise risk.
- Renal function assessment: adjust use in patients with impaired kidney function. - Age considerations: use cautiously in elderly patients due to increased susceptibility to tendon injury. - Photosensitivity: advise patients to avoid prolonged sun exposure. - Concomitant QT‑prolonging drugs: monitor cardiac rhythm. - Allergy history: avoid in individuals with known fluoroquinolone hypersensitivity. - Store at ambient temperature: keep in original container, protect from moisture and heat.
What does Norfloxacin interact with?
Norfloxacin can interact with other medicines, altering its efficacy or safety profile.
Major Interactions (Avoid): - Antacids containing magnesium or aluminum: significantly reduce absorption of Norfloxacin. - Warfarin: may increase anticoagulant effect, raising bleeding risk. - Corticosteroids: combined use raises risk of tendon rupture.
Moderate Interactions (Monitor Closely): - Theophylline: may increase plasma levels, requiring dose adjustment. - Diabetes medications (e.g., insulin, sulfonylureas): may cause hypoglycaemia, monitor blood glucose.
