Tetracycline instruction for use

Tetracycline tablets are broad-spectrum antibiotics. Due to the ability to destroy a large number of bacteria of various types, tetracycline is actively used for purulent and inflammatory diseases of the skin, as well as the respiratory and genitourinary systems. Due to the low cost, availability and variety of forms of release, the drug is in great demand in the pharmaceutical market.

Drug action

Once in the patient’s body, Tetracycline stops the growth and activity of bacterial cells by disrupting their vital processes. The list of bacteria subject to the action of the drug is quite wide:

  • Streptococcus
  • Salmonella.
  • Klebsiella.
  • Enterobacteria.
  • Pseudomonas aeruginosa and Escherichia coli.
  • Shigella and Neisseria.
  • The causative agent of anthrax.
  • Vibrio cholerae.
  • Actinomycetes and clostridia.
  • Mycoplasma and brucella.
  • Listeria, chlamydia and pertussis.

This is not the whole list of pathogens that Tetracycline can cope with.

The tablet dissolves quite quickly in the stomach and, getting into the small intestine, is absorbed into the blood. The distribution of the active substance throughout the body occurs unevenly, the main part of it accumulates in the lungs, lymph nodes and spleen. The decomposition of tetracycline hydrochloride by half occurs in the cells of the liver, while metabolic products do not harm the body and are excreted through the urine. Part of unchanged tetracycline enters the stomach with bile and enters the bloodstream again, which allows the active substance to stay in the body longer.

Indications for use

Doctors prescribe a drug for the treatment of inflammatory diseases of infectious etiology, given the fact that the pathogen is exposed to this medication. Tetracycline tablets help with the following diseases:

  • Infectious inflammation of the lungs and bronchi — pneumonia and bronchitis.
  • Cholecystitis is an inflammation of the gallbladder.
  • Accumulation of pus in the pleura of the lungs — empyema.
  • Gonorrhea and syphilis.
  • Brucellosis and intestinal infections.
  • Conjunctivitis, blepharitis.
  • Osteomyelitis is a specific infection of the bones with accumulation of pus.
  • Prostatitis.
  • Acne on the face and back, accompanied by an infectious lesion of the skin.
  • Cholera, tularemia, plague.
  • Anthrax, frambesia.
  • Infectious damage to the mucous membranes — stomatitis, gingivitis and others.

Preventive use is the prevention of infection of postoperative sutures.

If in the treatment of the disease there is a risk of developing blood poisoning, then tetracycline is recommended to be used in combination therapy with other bactericidal drugs.

With streptococcal angina, tetracycline group preparations are not used because of the immunity of beta-hemolytic streptococci to them.

The instruction for the use of tetracycline tablets with nystatin is practically no different from the usual drug and in any case requires a preliminary examination by a specialist. They are also dispensed from pharmacies by prescription only.

Dosage and terms of use

Dosage depends on the specific disease. The spectrum of action of this medication is very wide, i.e. reception schemes are also very many. In addition, doctors take into account the individual characteristics of the body of each patient.

Dosage for adults

For adults, the general intake regimen involves ingestion from 0.25 to 0.5 g of tetracycline 4 times a day or a double dose 2 times a day. The main thing is that the total amount of the drug taken does not exceed 4 g per day.

With pustules on the skin and concomitant infection, the drug is taken at 0.5−2 g per day, dividing the dose into several doses at equal intervals. So the reception is carried out for three weeks, after which the dosage can be reduced by half.

Brucellosis is a rather serious disease transmitted from some species of animals, in particular, from pigs through poor-quality meat. With it, you need to take tetracycline at least 0.5 grams 4 times a day. The course of treatment is 3 weeks. It is better to take this drug with streptomycin and other similar medicines.

Some sexually transmitted diseases are also successfully treated with tetracycline. For example, for the treatment of gonorrhea, the following scheme is used: the first time is 1.5 g, then 0.5 g every 6 hours. The minimum course of treatment takes 4 days, but this is only if there are no complications. Otherwise, more serious therapy is required. Syphilis is treated in the same way, but much longer — 2-4 weeks, depending on the stage of the disease.

Dosage for children

The dosage for children over 12 years old ranges from 6.25-12.5 mg per 1 kg of the child’s weight. Take tetracycline in tablets with a dosage of 100 mg is necessary every 6 hours or in a double dosage every 12 hours.


With the relative universality of the antibiotics of the tetracycline group, they still have their contraindications. First of all, these drugs can be taken by patients over 12 years old. During pregnancy, the use of Tetracycline is strictly prohibited, since it actively penetrates the placental barrier and negatively affects the fetus (up to the occurrence of congenital pathologies of the development of the musculoskeletal system)

For the same reasons, it can not be used for lactating women, since the antibiotic is excreted along with breast milk. If there is an urgent need to use this drug, then the child needs to be transferred to artificial mixtures for feeding.

In addition, tetracycline is contraindicated in persons suffering from the following diseases:

  • Leukopenia — a decrease in the content of the leukocyte component of the blood.
  • Renal or liver failure.
  • Any fungal infections, regardless of location.
  • Autoimmune lupus erythematosus.

Before starting treatment, the patient is tested for individual intolerance to tetracycline itself or additional components of the drug.

Side effects

Even properly prescribed treatment and compliance with all the rules and nuances does not exclude the occurrence of side effects:

  • The digestive system can respond by causing nausea and vomiting, lack of appetite, impaired intestinal activity — diarrhea or constipation. Also, inflammation of the mucous membrane of the oral cavity and esophagus, tongue, damage and necrosis of hepatocytes can occur.
  • From the nervous system, dizziness and paroxysmal headache may occur.
  • Taking tetracycline can cause a decrease in the number of red blood cells and platelets in the blood.
  • The skin can become hypersensitive to sunlight until the development of inflammatory processes, even with a short stay on the street.
  • Candidiasis complications of the course of the disease.
  • Minor allergic reactions in the form of urticaria and swelling of the face.

Side effects are relatively rare, but in case of any negative reactions, it is urgent to inform the attending physician about them.

Special instructions

Tetracycline tablets are available on prescription. Self-treatment is fraught with unpleasant consequences, so it is always necessary to consult a specialist. In addition to side effects, you also need to know about some of the features of the drug.

For example, during the entire course of treatment, you should refrain from dairy products: they make it difficult for the drug to enter the blood from the intestines. Vitamins of groups K and B, on the contrary, are recommended to be taken additionally, because their assimilation while taking an antibiotic is reduced.

Regarding the treatment of children, it should be borne in mind that during the period of the change of milk teeth, tetracycline is able to change the color of tooth enamel.

With a long course of treatment, it is necessary to periodically check the condition of the kidneys and liver, as well as donate blood for analysis.

If tetracycline is supposed to be used in parallel with other medicines, this fact must be agreed with the attending physician, since the antibiotic can interact with them differently. In addition, due to possible side effects from the central nervous system, it is not recommended to perform work that requires attention and reaction speed.


If the allowable concentration of the drug is exceeded, nausea, vomiting appears in the body, blood may appear in the urine. To eliminate these symptoms, a gastrointestinal tract is forcedly washed, and absorbent substances are also used to reduce the amount of medication. In order to completely cure the consequences of an overdose, inpatient treatment in a hospital is required.

The price of tetracycline tablets in a dosage of 500 mg and the cost of its analogues is very low compared to other antibiotics, which makes it very popular for the treatment of many diseases.

The drug Tetracycline has few analogues in Russia. Among them are Tetracycline-AKOS, Tetracycline-LekT, Tetracycline hydrochloride. All of them have a relatively low price with significant treatment effectiveness. However, choosing one of them, you must seek the advice of a specialist.
