Nitrofurantoin instruction for use

Nitrofurantoin is a drug that is used exclusively to treat urinary tract infections. The antibiotic can be used in both men and women; in children — only from the 2nd month of life.

Brief description of Nitrofurantoin (from the annotation): the drug belongs to the group of antibiotics of the nitrofuran series with bactericidal and bacteriostatic actions against gram-positive and gram-negative microflora (streptococcus, staphylococcus, salmonella, E. coli, shigella, Proteus).

The predominant effect is the bacterial microflora of the urogenital tract (the drug is completely excreted through the kidneys in 50% unchanged form).

The main antibacterial property of Nitrofurantoin is the blocking of oxidation processes, the violation of the energy supply of the cell, the blocking of the respiration processes of the microorganism, leading to its death.

Indications for use

Indications for the use of Nitrofurantoin are:

  • bacterial (acute and chronic, complicated and uncomplicated) diseases of the genitourinary system (cystitis, urethritis, pyelonephritis);
  • prevention of bacterial complications during operations on the organs of the urogenital tract or diagnostic studies;


contraindications for the use of Nitrofurantoin:

  • intolerance (allergy) of the components of the drug (even in the past), severe renal failure;
  • liver failure in the presence of chronic hepatitis or cirrhosis;
  • severe heart failure;
  • disruption of the enzyme glucose-6-phosphate dehydrogenase;
  • pregnancy, lactation (breastfeeding);
  • children up to 1 month;

Special instructions

Concomitant use of the drug with alcohol is not recommended.

Do not use fluoroquinolones, quinolones (nalidixic acid, pefloxacin, norfloxacin, etc.) in conjunction with drugs, which can lead to a sharp decrease in the activity of nitrofurantoin.

Cautiously prescribed with drugs that enhance the excretion of uric acid from the body (for example, sulfinpyrazone) — the excretion of Nitrofurantoin decreases and the risk of its side effects increases.

Not addictive.


It is taken orally, immediately after eating. Tablets should be washed down with water in a sufficient volume, at least a glass.

The duration of treatment with nitrofurantoin for cystitis and other acute infections is 7-10 days, 100 mg 3-4 times a day. If the drug is prescribed in order to prevent relapse, then the duration of the course is determined by the doctor.

For surgical prophylaxis, 100 mg of the drug is prescribed twice a day on the day of surgery and for three days after.

Nitrofurantoin during pregnancy and lactation

The drug is contraindicated in pregnant women. Women who are breastfeeding should be temporarily abandoned during antibiotic therapy, as the medicine is excreted in breast milk and may cause sensitization in the baby.

Nitrofurantoin and Alcohol

It is strictly forbidden to drink alcohol if a course of antibiotic therapy with this drug is prescribed. It is metabolized by liver cells, which neutralize ethanol, which creates an intense load on the organ. The toxic effect on the liver is one of the side effects of the drug, which is repeatedly enhanced by the use of alcohol.

The effectiveness of antibiotic therapy is also reduced, since the drug is excreted by the kidneys, and the diuretic effect of alcoholic beverages accelerates this process and prevents the creation of the desired concentration of the active substance.

Side effects

side effects of nitrofurantoin:

  • dyspeptic complaints (nausea, vomiting, abdominal pain, instability of the nature of the stool, etc.), hepatitis, cholestatic jaundice, hepatitis, headaches, dizziness, drowsiness, fatigue, allergic reactions, cough, bronchial obstruction (respiratory failure, shortness of breath).
  • Side effects are rare because the drug is well tolerated in most cases. In cases of overdose, which are extremely rare, you must immediately immediately stop taking the drug and consult a doctor (symptoms: nausea, vomiting, dizziness).
