What is Doxycycline

Doxycycline is a bactericidal, semi-synthetic antimicrobial medicine that belongs to tetracyclines. The principle of its action is associated with a slowdown (stop) of protein synthesis in sensitive microorganisms.

The active component of the drug in the digestive tract is well absorbed. The absorption of the antibiotic is not dependent on food intake, the peak concentration of doxycycline is observed 2 hours after taking the drug. Doxycycline, among other tetracyclines, penetrates better into the tissues of the body, due to its high lipophilicity. About 80-90% of the antibiotic binds almost completely to plasma proteins. The main half-life of doxycycline is about 12-18 hours with a single use and up to 22-24 hours with normal regular antibiotic intake.

Dosage and method of using Doxycycline

Doxycycline is for oral use. It is recommended to take the tablets whole with a large amount of liquid. The antibiotic should be taken during meals, do not drink the drug with milk or dairy products. It is not recommended to take the drug immediately before bedtime.

For especially severe infections, it is recommended to take a dose of 4mg/kg of the patient’s weight per day throughout the course.
The duration of treatment is usually from 7 to 14 days, treatment must be continued for at least three days after the symptoms of the disease have disappeared.
In such infections that caused staphylococci (beta hemolytic), the duration of treatment should be at least ten days.

Doxycycline side effects

During therapy with Doxycycline in patients, the development of such undesirable effects is possible:

1. From the side of the heart, blood vessels and hemopoietic system: tachycardia, leukopenia, leukocytosis, anemia, thrombocytopenia, coagulation disorders, lymphadenopathy. In isolated cases, the presence of toxic granularity in granulocytes and atypical lymphocytes was also noted.

2. From the central nervous system: paresthesia, decreased visual acuity, increased intracranial pressure, excessive excitability, generalized convulsions.

3. From the gastrointestinal tract and liver: heartburn, flatulence, nausea, vomiting, impaired stool, stomatitis, glossitis, discoloration of the teeth. It is also possible the development of pseudomembranous enterocolitis, which may require discontinuation of the drug doxycycline.

4. From the urinary system: hematuria, impaired renal function (function), nephritis (interstitial), anuria.

Allergic reactions: photosensitivity, skin itching, urticaria, bronchospasm, erythema, Lyell syndrome, Quincke edema, Stevens-Johnson syndrome, anaphylactic shock. It is also possible the development of a reaction that is accompanied by hyperthermia, headache and arthralgia.
Others: pain in muscles and joints, impaired taste and smell, vaginal and oral candidiasis, itching in the anus, hypertrichosis. In addition, doxycycline may increase plasma residual nitrogen levels.

With the development of undesirable effects, you should discontinue the drug and consult a doctor as soon as possible, who will decide on the possibility of further use of doxycycline or prescribe alternative therapy.


Doxycycline is contraindicated in people with individual sensitivity to doxycycline and other tetracycline drugs, as well as excipients of the drug.

The antibiotic is contraindicated in patients with severe renal and hepatic impairment.

Doxycycline is not used for the treatment of children (patients) under eight years of age, because the use of this drug during the development of teeth can have an irreversible effect on the color of tooth enamel.

Caution is necessary when prescribing an antibiotic to patients suffering from arrhythmias, as well as to patients who are exposed to ultraviolet rays (since the risk of developing photosensitization should not be exposed to sunlight for a long time, as well as visiting a solarium during doxycycline therapy).

Doxycycline is prescribed with caution to people who operate unsafe mechanisms and drive a car.

Doxycycline overdose

An overdose of doxycycline in patients showed the development of impaired liver function, as well as undesirable effects from the gastrointestinal tract.

There is no specific antidote. With intoxication with doxycycline, gastric lavage and symptomatic agents are prescribed.

In case of an overdose, it is also possible to prescribe calcium preparations, since doxycycline forms complexes (chelate) with calcium ions.

Conducting dialysis (peritoneal) and hemodialysis for poisoning is ineffective.
