Nicoumalone

Anticoagulant

Uses of Nicoumalone

  • Nicoumalone is primarily used to manage thromboembolic disorders, that is, conditions characterised by harmful blood clots in blood vessels. It belongs to the class of medications called oral anticoagulants.

Side effects of Nicoumalone

  • Bleeding from the gums and nose
  • Prolonged bleeding after getting a cut
  • Increased menstrual flow
  • Abdominal pain and diarrhoea
  • Rash or itching
  • Hair loss

How Nicoumalone works

  • Nicoumalone works by blocking the liver's synthesis of vitamin K-dependent clotting factors II, VII, IX, and X. Vitamin K is necessary for these clotting proteins to form. By inhibiting these clotting factors, nicoumalone effectively decreases the ability of the blood to clot excessively. This reduces the risk of harmful blood clots forming inside blood vessels while still allowing normal clotting when required to prevent excessive bleeding.

Special Dietary and Lifestyle Recommendations

  • To support a speedy recovery, avoid alcohol and junk food, stick to freshly prepared home-cooked meals, and get adequate rest. 
  • Replacing saturated fats with unsaturated fats can help lower total and LDL cholesterol levels in a short time. Foods like avocados, olive oil, fatty fish, and nuts are rich in heart-healthy unsaturated fats and should be consumed regularly.
  • Include vitamin K-rich foods such as liver, leafy green vegetables, and vegetable oils, as Nicoumalone may reduce vitamin K levels in the body. Additionally, avoid alcohol consumption, as it increases the risk of gastrointestinal ulcers and bleeding.

Frequently asked questions

Nicoumalone usually starts working within 24 to 72 hours, but its full anticoagulant effect may take several days. Regular blood tests (INR/PT) are needed to monitor its effectiveness.

Avoid activities that increase the risk of bleeding or injury. Inform your doctor about any other medications, including herbal supplements. Regularly monitor your blood clotting levels and avoid alcohol or vitamin K-rich foods in excess.

No, stopping Nicoumalone abruptly can increase the risk of blood clots. Always consult your doctor before discontinuing or adjusting the dosage.

Nicoumalone should be used cautiously in patients with kidney or liver disease, as it can increase the risk of bleeding and may require dose adjustments. Regular monitoring is essential.

There is no strong evidence that Nicoumalone affects fertility, but it is not recommended during pregnancy due to potential risks to the baby. Consult your doctor if you are planning to conceive.

Nicoumalone is used to prevent and treat various thromboembolic diseases, including deep vein thrombosis (blood clots in leg veins) and pulmonary embolism (blood clots in the lung). It works by slowing down blood clotting, reducing clotting proteins in the blood, and helping maintain smooth blood flow, thus preventing strokes and heart attacks.
