Hepatic insufficiency, leukopenia, mycoses, children under 8, pregnancy, lactation (breastfeeding), hypersensitivity to tetracycline.
PREGNANCY AND LACTATION

Penetrates through the placental barrier. May cause long-term discoloration of the teeth, hypoplasia of the enamel, suppression of the growth of the bones of the fetal skeleton. In addition, tetracycline may be the cause of the development of fatty liver infiltration.
APPLICATION FOR VIOLATIONS OF THE FUNCTION OF KIDNEYS
Contraindicated in liver failure.
APPLICATION FOR CHILDREN
Contraindicated in childhood to 8 years. The use of tetracycline in children during the development of teeth can lead to an irreversible change in their color.
SPECIAL INSTRUCTIONS
With prolonged use, it is necessary to periodically monitor the functions of the kidneys, liver, and hematopoiesis.
The use of tetracycline in children during the development of teeth can lead to an irreversible change in their color.
During the treatment for the prevention of hypovitaminosis should be used vitamins B, K, brewer's yeast.
Tetracycline should not be taken concomitantly with milk and other dairy products. at the same time, absorption of the antibiotic is impaired.
DRUG INTERACTION
Preparations containing metal ions (antacids, preparations containing iron, magnesium, calcium) form inactive chelates with tetracycline, therefore it is necessary to avoid their simultaneous appointment.
It is necessary to avoid the combination with penicillins, cephalosporins, which have bactericidal action and are antagonists of bacteriostatic antibiotics (including tetracycline).
With the simultaneous use of tetracycline with retinol may develop intracranial hypertension.
When used simultaneously with colestyramine or colestipol, there is a violation of absorption of tetracycline.
