Norfloxacin is a fluoroquinolone antibiotic commonly prescribed for urinary tract infections (UTIs), including cystitis and complicated UTIs. It works by inhibiting bacterial DNA gyrase, preventing bacterial replication. The typical adult dose is 400 mg every 12 hours, with duration depending on the infection severity.
As of 2026, norfloxacin remains available in many countries, but its use has declined due to safety concerns and the rise of antibiotic resistance. The U.S. FDA has restricted fluoroquinolone use for uncomplicated infections due to risks of tendonitis, tendon rupture, and peripheral neuropathy. In the European Union, norfloxacin is approved but with strict warnings.
Availability of norfloxacin 400mg tablets may be limited to prescription-only status in most regions. Some online platforms list it under paid plans, but consumers should only obtain it through legitimate pharmacies with a valid prescription. Self-medication is strongly discouraged.
Common side effects include nausea, dizziness, and headache. Serious adverse effects, though rare, require immediate medical attention. Patients with a history of tendon disorders or myasthenia gravis should avoid this drug.
For current availability and pricing, consult a healthcare provider or a licensed pharmacy. Always follow the prescribed dosage and complete the full course to prevent resistance.
