Overdose

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.
