Patients with impaired renal function (creatinine clearance less than 20 ml / minute or serum creatinine level more than 5 mg / 100 ml) and patients undergoing blood purification (hemodialysis) should be prescribed 1 full dose 1 time per day or ½ the therapeutic dose 2 times a day.

Side effects

  • Allergic reactions: edema, urticaria, pruritus, Stevens-Johnson syndrome;
  • From the digestive system: bitterness in the mouth, anorexia, diarrhea, nausea, vomiting, pain in the abdominal cavity, increased activity of hepatic transaminases; with prolonged use - pseudomembranous enterocolitis;
  • From the urinary system: crystalluria, dysuria, albuminuria, polyuria, glomerulonephritis, hypercreatininemia, urethral bleeding;
  • From the nervous system: headache, dizziness, insomnia, hallucinations;
  • From the side of the cardiovascular system: arrhythmias, tachycardia, vasculitis, fainting, decreased blood pressure;
  • From the side of the musculoskeletal system: tendonitis, arthralgia, tendon ruptures;
  • On the part of the hematopoietic organs: an increase in the level of eosinophilic blood cells, a decrease in the number of leukocytes per unit of blood volume, a decrease in hematocrit;
  • Others: candidiasis.

special instructions

To prevent the development of crystalluria during treatment, it is recommended to drink plenty of fluids (under the control of diuresis).

It should be borne in mind that norfloxacin increases the prothrombin index. Patients should warn the doctor about taking Norbactin if surgery is necessary, since the blood coagulation system must be monitored during surgery.

During treatment, it is necessary to avoid exposure to direct sunlight, due to the likelihood of developing dizziness - be careful when driving a car and performing potentially hazardous types of work that require increased attention and high reaction speed.

When the first signs of inflammation of the muscle tendon (tendovaginitis) or pain in the tendons appear, discontinue the drug and consult a doctor for examination.

Drug interactions

When combined with drugs that can lower blood pressure, barbiturates or anesthetics, it is necessary to monitor the heart rate, blood pressure and electrocardiogram indicators.

With the simultaneous use of warfarin, coagulation indicators should be constantly monitored.

Norfloxacin reduces the clearance of theophylline by 25% (a decrease in its dose is required), increases plasma concentrations of cyclosporine and indirect anticoagulants.

Antacids containing magnesium or aluminum hydroxide, as well as preparations containing sucralfate, zinc or iron, reduce the absorption of norfloxacin, therefore, intervals of at least 4 hours should be observed between taking these agents.

The simultaneous use of drugs that can lower the seizure threshold is fraught with the development of epileptiform seizures.

Norfloxacin, used during treatment with nitrofurans, reduces their effect.


Analogues of Norbactin are: Nolitsin, Norfloxacin, Normaks, Loxon-400.
