T45.7

Clinical Causes: Accidental overdose of anticoagulant antagonists such as vitamin K antagonists Incorrect administration or dosing of vitamin K or other coagulants Drug interactions leading to increased anticoagulant effects Failure to monitor blood clotting parameters properly Ingestion of contaminated or improperly stored medications Intentional overdose in cases of self-harm

Key Symptoms: Excessive bleeding from cuts or injuries Unusual bruising or hematomas Blood in urine or stool Pain or swelling at injection sites Nosebleeds or bleeding gums Signs of internal bleeding such as dizziness, weakness, or fainting Uncontrolled bleeding episodes in severe cases

Diagnosis Path: Diagnosis relies on a combination of medical history, medication review, and laboratory tests. Blood tests, such as INR (International Normalized Ratio), are crucial for assessing the blood's clotting ability. Elevated INR levels indicate a high risk of bleeding due to anticoagulant effects, while low levels may suggest underdosing. A thorough clinical examination helps identify signs of bleeding or related complications. Healthcare providers may also review medication adherence and possible interactions to identify contributing factors.

Treatment Protocols: Treatment focuses on managing bleeding complications and restoring normal blood clotting. Key approaches include: - Discontinuing or adjusting the dosage of anticoagulant antagonists - Administration of vitamin K to reverse the effects of vitamin K antagonists - Use of blood products such as fresh frozen plasma or specific clotting factors in severe bleeding - Supportive care to stabilize the patient, including fluids and blood transfusions if necessary - Monitoring and managing any underlying conditions that contributed to the poisoning It is essential that treatment be guided by healthcare professionals to avoid further complications and ensure effective reversal of anticoagulant effects.
