No drug interactions have been described with external and local use of Tetracycline.

When taking tetracycline orally, possible interactions should be considered:

  • magnesium-, aluminum- and calcium-containing antacids, cholestyramine and iron preparations reduce the absorption of tetracycline;
  • chymotrypsin increases the concentration of tetracycline and the duration of its circulation;
  • retinol increases the likelihood of increased intracranial pressure.

When used simultaneously with indirect anticoagulants, the prothrombin index decreases; with penicillins and cephalosporins – the effectiveness of these drugs decreases; with estrogen-containing oral contraceptives - the contraceptive effect is reduced and the risk of breakthrough bleeding increases.

special instructions

Due to the possible development of photosensitivity, it is necessary to limit insolation. With long-term use, periodic monitoring of the function of the kidneys, liver, and hematopoietic organs is necessary. It can mask the manifestations of syphilis, and therefore, if a mixed infection is possible, monthly serological analysis is necessary for 4 months. All tetracyclines form stable complexes with Ca2+ in any bone-forming tissue. In this regard, intake during the period of tooth development can cause long-term staining of teeth in a yellow-gray-brown color, as well as enamel hypoplasia. To prevent hypovitaminosis, vitamins B and K and brewer's yeast should be prescribed.

Tetracycline tablets - instructions for use for adults

The antibiotic is taken orally in tablet form. The drug is swallowed without chewing and washed down with a small amount of water. It is not recommended to replace liquid with other drinks - tea, juices, milk. This will affect the rate of absorption of the medication.

To maintain optimal drug concentrations, it is necessary to maintain an interval between tablet doses. So, for adult patients it is 6-8 hours.

The dosage for an adult varies depending on the nature of the disease and ranges from 200 to 500 mg.

DiseaseSingle dosageNumber of appointments per day (times)Duration of treatment (days)
Genital infections (gonorrhea, syphilis)500 mg47-10
Acne500-2000 mg421
Intestinal disorders250-500 mg3-45-7
Inflammation of the respiratory system500 mg47
Cystitis, pyelonephritis500 mg47

The maximum safe daily dose of the drug is 4 g.

Interaction

Due to the suppression of intestinal microflora, it reduces the prothrombin index (requires a reduction in the dose of indirect anticoagulants). Reduces the effectiveness of bactericidal antibiotics that disrupt cell wall synthesis (penicillins, cephalosporins). Reduces the effectiveness of estrogen-containing oral contraceptives and increases the risk of breakthrough bleeding; retinol - risk of developing increased intracranial pressure. Absorption is reduced by antacids containing Al3+, Mg2+ and Ca2+, Fe preparations and cholestyramine. Chymotrypsin increases the concentration and duration of circulation.

Tetracycline tablets - instructions for use for children

The antibiotic is included in treatment regimens for children over 8 years of age. The child takes it at intervals of 6 hours in an individual dosage. The amount of tetracycline hydrochloride recommended by pediatricians for children is determined based on body weight. The calculation is based on the formula 12-25 mg per kilogram of weight:

  • for acute intestinal infections, infectious pathologies of the gastrointestinal tract - 12-20 mg per kg every 6 hours;
  • for inflammation of the urinary organs - 20-25 mg per kg 4 times a day.

So, for acute cystitis, a child who weighs 30 kg should receive 750 mg of medication per day. This volume is divided into 3 doses (250 mg - 2.5 tablets) with an interval of 6 hours.

Applications and dosages

The drug Tetracycline is indicated for oral administration. Tablets should be taken with plenty of liquid.

The wide range of indications for use explains the wide variability of dosage and administration regimens in the treatment of various ailments. For a more detailed description of the method of use and the required dosages, you should contact a medical institution for consultation with a doctor.

In case of an overdose of Tetracycline, symptoms such as attacks of nausea, vomiting and dizziness occur. In more complex cases, hematuria (blood in the urine) appears. If these symptoms develop, it is recommended to take measures to cleanse the stomach and intestines, as well as take sorbents.

Tetracycline tablets - instructions for use for diarrhea

The antibiotic is effective for digestive disorders of a bacterial nature. Such diseases can be caused by:

  • salmonella;
  • coli;
  • pathogenic microorganisms.

For diagnosis, contact a medical facility. Tetracycline tablets are prescribed if the bacterial nature of the disease is established.

Standard dosage:

  • 250 mg for mild diarrhea without other associated symptoms;
  • 500 mg for frequent diarrhea (more than 4 times a day) against a background of fever, nausea, and abdominal pain.

In the first three days, Tetracycline tablets are taken every 6 hours to stop the proliferation of pathogenic bacteria, then the drug is taken at intervals of 12 hours for another 3-4 days.

The dose of the drug for children depends on their weight. The drug is given at the rate of 12-20 mg per kilogram of weight. The resulting amount is divided into three doses. The medication is approved after 8 years.

When treating diarrhea with Tetracycline, keep in mind that the antibiotic acts exclusively on the bacterial flora. If an unpleasant symptom is caused by a virus, then you will need to choose a different treatment regimen.

Reviews

Oleg. Three years ago I developed sinusitis, a complication after the flu. I hoped that it would go away on its own, so I didn’t go to the hospital for a long time. It all got to the point where the doctor pierced the sinus twice. The doctor also prescribed me Tetracycline. I took the drug for five days, but then decided to take it for another week. Due to prolonged use, I was covered in everything. I had to get rid of this problem with other medications. But Tetracycline helped with sinusitis.

Ksenia. I often get a rash on my face and décolleté. I tried many medications, including many expensive ones. At my last appointment, the doctor diagnosed me with furunculosis and prescribed tetracycline ointment. The tube cost only 26 rubles. The ointment itself is white and does not smell of anything. At first I applied the product directly to the skin, but it left stains on clothes and bed linen, as it was poorly absorbed. Then she began to apply a bandage to the treated areas. Pimples and redness gradually disappeared. There were no scars or scars left on the skin.

Olga. I was prescribed tetracycline for cystitis. It took five days to drink it, but the effect was noticeable already on the second day. During treatment, my blood pressure rose sharply. Then I didn’t attach any importance to it and didn’t see the connection between feeling unwell and taking the medicine. When I was again tormented by cystitis, I was once again prescribed Tetracycline. The blood pressure situation recurred, so I stopped taking this drug. The antibiotic had to be changed to another. If it weren’t for the side effect, then I would always take it during relapses.

Pharmacology

Streptococcus spp., including Streptococcus viridans, Streptococcus pneumoniae (however, beta-hemolytic streptococci of group A, including 44% of Streptococcus pyogenes strains and 74% of Streptococcus faecalis strains are resistant to tetracycline), is also effective against other microorganisms: Actinomyces spp.

, Bacillus anthracis, Balantidium coli, Borrelia recurrentis, Chlamydophila (Chlamydia) psittaci, Chlamydophila (Chlamydia) trachomatis, Clostridium spp., Entamoeba spp., Fusobacterium fusiforme, Mycoplasma pneumoniae, Rickettsiae, Propionibacterium acnes, Treponema pallidum, Treponema pertenue, Ureaplasma urealyticum.

Microorganisms resistant to tetracycline: Pseudomonas aeruginosa, Proteus spp., Serratia spp., most strains of Bacteroides spp. and fungi, viruses.

bile, synovial, ascitic, cerebrospinal (in the latter the concentration is 10–25% of that in plasma), selectively accumulates in bones, liver, spleen, tumors, teeth. Passes through the placenta and enters breast milk. Volume of distribution - 1.3–1.6 l/kg. Slightly metabolized in the liver.

T1/2 - 6-11 hours, with anuria - 57-108 hours. It is found in urine in high concentration 2 hours after administration and remains at an effective level for 6-12 hours; in the first 12 hours, up to 10–20% of the dose is excreted by the kidneys. In smaller quantities (5–10% of the total dose) it is excreted with bile into the intestine, where partial reabsorption occurs, which promotes long-term circulation of the active substance in the body (enterohepatic circulation). During hemodialysis it is removed slowly.

Tetracycline tablets - price

The cost of the medication varies from 40 to 60 rubles, depending on the manufacturer:

  • Biosynthesis of PAO – from 55 rubles;
  • Biokhimik JSC – from 45 rubles;
  • Tyumen Chemical Plant OJSC – from 60 rubles.

In Ukraine, the medicine can be purchased for 14-16 UAH.

The low cost along with its effectiveness makes Tetracycline an indispensable antibiotic in the treatment of bacterial infections.
