Instructions for use

The antibiotic Ampicillin was developed in 1961 by British pharmacists. It has antibacterial activity against a wide range of pathogenic microorganisms and fights mixed infections. Since its introduction into use, the drug has not lost its relevance and is still considered an effective and inexpensive antibiotic.

The active substance of the drug is ampicillin trihydrate. This is a component of semi-synthetic production, which is part of the penicillin group. The substance acts on the cell membrane of dividing microorganisms and disrupts peptide bonds in the membrane. As a result, the bacterial cell becomes unstable, ceases to divide and undergoes lysis (dissolution).

The pharmaceutical preparation prevents the division and spread of gram-positive and gram-negative microorganisms: Pfeiffer sticks, staphylococci, streptococci, shigella, salmonella, proteins, Escherichia coli, pertussis bacilli, clostridia, gonococci and others. Infectious pathogens are resistant to ampicillin.


The instructions for the use of the drug indicate the following indications associated with a certain localization of the infection:

  • Respiratory organs – bronchitis, pneumonia, including those accompanied by abscesses;
  • The upper respiratory tract and ENT organs – tonsillitis, tonsillitis, otitis media, pharyngitis, sinusitis;
  • Urinary tract – pyelitis, cystitis, pyelonephritis;
  • Gastrointestinal tract and abdominal cavity – Salmonella lesions, cholecystitis, cholangitis, typhoid fever, dysentery, peritonitis;
  • Female genital area – ovarian infections, chlamydia in pregnant women, adnexitis;
  • Common diseases – rheumatism, meningitis, sepsis, septicemia, scarlet fever, gonorrhea, pasteurellosis, listeriosis;
  • Lesions of the skin and soft tissues, impetigo, dermatosis.

How to use for Adults

The tactics of treatment with ampicillin will depend on the location of pathogenic microorganisms, the severity of the infectious process and the type of pathogen. Before use, a laboratory study is carried out on the sensitivity of the isolated pathogen to ampicillin and the tolerance of the active substance to the patient (allergy test).

The tablets and capsules of the drug are used for oral use. The average daily dose for adult patients is from 1000 to 2000 mg per day, which is divided into 4 doses. The maximum daily dose of an antibiotic is 4 g.

For the treatment of gonococcal urethritis, the medicine is taken once in an amount of 3.5 g. All antibiotics in the form of tablets and capsules are taken 1 hour before a meal.

How to use for Children

A special form of ampicillin has been developed for young patients, which should be taken in suspension. For its preparation, the granules contained in the vial are poured with drinking water to the indicated risks and shaken vigorously until a uniform consistency is formed. Dosing the medicine is very convenient with a measuring spoon, which is sold in a package with ampicillin. You should take the drug before meals with a little water.

Children who know how to swallow tablets can take the medicine in tablet form – it is used regardless of the meal and washed down with water.

In severe cases, the child may be prescribed ampicillin by injection, and with sore throats, gargling with ampicillin powder diluted with water helps well. The procedure can be performed for children over 5 years old, who understand what rinsing is.

The daily dose of ampicillin for a child is determined in strict accordance with the weight: 1 kg from 50 to 100 mg of the active substance.

For children whose body weight is less than 20 kg, the norm is reduced to 12.5-25 mg of ampicillin per 1 kg of weight. The entire daily dose is divided into several doses – from three to six.
