Warfarex tablets are indicated for:
Active substance: warfarin;
1 tablet contains 3 mg of sodium warfarinate (as sodium warfarinate clathrate);
Excipients: lactose, monohydrate; microcrystalline cellulose; crospovidone; magnesium stearate; indigo carmine (E 132) (for 3 mg tablets) and crimson 4R (E 124) (for 5 mg tablets).
Warfarex must be used at the same time.
The dose of Warfarex is determined by the doctor for each patient individually, guided by the INR indicators of prothrombin.
Target INR range for oral anticoagulant therapy.
Prevention of thromboembolic complications in patients with prosthetic heart valves: INR - 2.5-3.5. Other indications: INR - 2.0–3.0.
Pregnant
Contraindicated.
Children
Anticoagulant therapy in children should be carried out as directed and under the supervision of pediatricians.
Drivers
Does not affect.
Symptoms: bleeding, bleeding.
Treatment: In mild cases, with gradual overdose, it is usually sufficient to reduce the dose or stop treatment with warfarin until the INR returns to the target level. In acute preparation overdose, emptying the stomach is not recommended due to the risk of bleeding. Activated charcoal should be reused to avoid absorption and enterohepatic recirculation of warfarin. When using activated charcoal parenterally (i / v), vitamin K should be administered. If bleeding develops, the effect of warfarin should be discontinued using vitamin K (intravenously at a dose of 5-10 mg), coagulation factor concentrate, or fresh frozen plasma. If necessary, further anticoagulation should avoid the use of vitamin K at a dose of more than 10 mg. Otherwise, the patient may be resistant to warfarin therapy for 2 weeks.
From the nervous system: subdural hematoma, fever.
From the circulatory and hematopoietic system: hemorrhage, coumarin necrosis, purple staining of the toes, purpura, eosinophilia, vasculitis, anemia, decreased hematocrit.
From the respiratory system, chest and mediastinum: tracheal calcification, hematorx.
From the gastrointestinal tract: nausea, vomiting, vomiting of blood, diarrhea, abdominal pain, gastrointestinal bleeding, rectal bleeding, melena.
From the hepatobiliary system: a reversible increase in the activity of liver enzymes, cholestatic hepatitis, jaundice.

Fibrinolytics such as streptokinase and alteplase are contraindicated in patients taking warfarin.
It is necessary to avoid the simultaneous use of warfarin or use it with caution under close clinical and laboratory supervision with thrombin inhibitors, unfractionated heparins and their derivatives, heparin with low molecular weight, fondaparin, rivaroxaban, antagonists of glycoprotein IIb / IIIa receptors, serotoramine reverse capture, inhibitors
Excessive alcohol consumption against the background of liver failure potentiates the effect of warfarin. The quinine in Tonic water can also increase the effect of warfarin.
