Method of administration and dosage

Adults weighing 50 kg - 70 kg, adolescents and children over 8 years old on the 1st day take 200 mg of doxycycline, and on the following days - 100 mg of doxycycline.

For severe illnesses or patients weighing over 70 kg, 200 mg of doxycycline is prescribed daily throughout the course of treatment.

The dosage for children over 8 years old (weighing less than 50 kg) is 4 mg / kg of body weight in 1 dose on the first day, which corresponds to 100-200 mg of doxycycline, and 2 mg / kg of body weight in 1 dose, which corresponds to 50 -100 mg doxycycline on the following days. Since the tablets of Doxycycline STADA® 100 mg and 200 mg are indivisible, it may be difficult to properly dose the drug in this group of patients.

The duration of therapy depends on the course of the disease and is prescribed by the doctor. The average duration of therapy is 5-21 days.

In the treatment of bacteriologically confirmed β-hemolytic streptococcus infection with doxycycline, the duration of treatment is at least 10 days to prevent late complications such as rheumatic fever or glomerulonephritis.

Special dosage recommendations

Acute gonorrheal urethritis in men and acute gonococcal infections in women - 200 mg of doxycycline per day for 7 days.

Acute gonococcal epididymitis - 200 mg of doxycycline per day for 10 days.
The success of treatment for gonococcal infection should be checked 3-4 days after the end of therapy.
Syphilis (primary and secondary form for allergy to penicillins) - 300 mg of doxycycline per day (can be taken at a time), the duration of treatment is 10 days.
Lyme disease (stage I) - 200 mg of doxycycline for 14 days.

Mode of application

Doxycycline STADA® tablets are taken regularly during meals with plenty of liquid (but not milk). Taking the drug with meals reduces the incidence of side effects from the gastrointestinal tract and, only to a small extent, affects the absorption of doxycycline. In addition, before taking the tablets, you can dissolve them (by stirring) in a glass of water. The solution should be drunk completely.

Contraindications

- hypersensitivity to tetracyclines or other component of the drug

Drug interactions

The absorption of doxycycline from the gastrointestinal tract is reduced under the influence of 2- or 3-valent cations of aluminum, calcium (milk, dairy products and calcium-containing fruit juices) and magnesium, which are part of antacids, as well as under the influence of iron preparations, activated carbon and cholestyramine... Therefore, medicines or food products containing these cations should be taken at intervals of 2-3 hours relative to the time of taking doxycycline.

Rifampicin, barbiturates, anticonvulsants (carbamazepine, diphenylhydantoin and primidone), as well as chronic alcohol abuse, due to the induction of enzymes in the liver, accelerate the metabolism of doxycycline. As a result, the therapeutically effective blood concentrations of doxycycline cannot be achieved with the usual doses of the drug.
Doxycycline enhances the action of sulfonylureas (oral antidiabetic agents) and anticoagulants such as dicumarol. With combined use, it is necessary to monitor blood sugar levels and blood coagulation parameters and, if necessary, reduce the dose of the above drugs.

With the simultaneous use of doxycycline and cyclosporin A, the toxic effect of the immunosuppressant increases.
Doxycycline therapy in combination with methoxyflurane anesthesia can lead to renal failure.

Before starting treatment, during it, and immediately after treatment with isotretinoin for acne, you should refrain from therapy with doxycycline, since both drugs can cause an increase in intracranial pressure.

The simultaneous administration of doxycycline and beta-lactam antibiotics should be avoided, as this leads to a decrease in antibacterial effectiveness.

With the simultaneous use of theophylline and tetracyclines, the likelihood of side effects from the gastrointestinal tract increases.

Special instructions

Patients with impaired renal function do not need to reduce the dose of doxycycline.
With prolonged use, it is necessary to regularly conduct blood tests, liver and kidney function.
During treatment with doxycycline, sunbathing in the open air or in solariums should be avoided, due to the possibility of phototoxic reactions.

It should be borne in mind that due to the intake of antibiotics of the tetracyclines group, the determination of the level of sugar, protein, urobilinogen and catecholamines in the urine may be inaccurate.
With doxycycline therapy, the reliability of the contraceptive action of hormonal contraceptives may be questioned. Therefore, it is recommended to additionally use non-hormonal contraceptives.

In the case of the development of pseudomembranous colitis, depending on the severity of the underlying disease, a decision should be made to discontinue therapy with STADA® Doxycycline, and if necessary, appropriate treatment should be carried out (taking specific antibiotics and chemotherapeutic agents, the effectiveness of which has been clinically proven) without discontinuing the drug.

Application in children

For children over 8 years old, doxycycline is prescribed only for the treatment of diseases that pose a threat to the child's life and only after a careful assessment of the potential benefits and possible risks.
Features of the effect of the drug on the ability to drive a vehicle or potentially dangerous mechanisms
Given that in some cases, when taking tetracyclines, the development of transient myopia (myopia) has been reported, caution should be exercised when driving a car and servicing potentially dangerous mechanisms.

Overdose

Symptoms: Acute intoxication with doxycycline has not yet been described in the literature. However, in case of overdose, there is a danger of parenchymal lesions of the liver and kidneys, as well as pancreatitis.
Treatment: In case of an oral overdose of doxycycline, the still unabsorbed substance should be bound into non-absorbable chelate complexes by taking antacids or calcium and magnesium salts. Treatment with the drug should be discontinued immediately. Symptomatic treatment is carried out. Hemodialysis or peritoneal dialysis is ineffective.
