Common Side Effects of Coumadin
Serious Side Effects of Coumadin
Coumadin is a prescription medication used to treat blood clots, reduce the risk of stroke and heart attack, and to treat or prevent venous thrombosis and its extension, or pulmonary embolism. It works by inhibiting the synthesis of vitamin K dependent clotting factors II, VII, IX and X, and the anticoagulant proteins C and S.
Coumadin is available as 1 mg, 2 mg, 2.5 mg, 3 mg, 4 mg, 5 mg, 6 mg, 7.5 mg and 10 mg tablets. The usual initial dose is 2 to 5 mg per day for 2 to 4 days or until the INR has reached the international normalized ratio (INR) of 1.5 to 2.0. Dosage is then adjusted based on the patient's INR.

Harmful Blood Clots: Risks, Symptoms and Prevention
Blood clots, medically known as thrombi, can form in the veins and arteries of the body. While some blood clots are harmless, others can be dangerous and even life-threatening if they break loose and travel to vital organs like the lungs or brain. This article will explore the risks and consequences of harmful blood clots that can occur in the veins, lungs, and heart, and discuss prevention strategies to reduce the risk of developing these dangerous clots.
Venous Thrombosis
Venous thrombosis refers to the formation of a blood clot (thrombus) inside a vein. This type of clot most commonly develops in the lower extremities, such as in the deep veins of the legs. When a blood clot forms in the deep veins, it is called deep vein thrombosis (DVT). DVT is a serious condition because the clot can break loose and travel to the lungs, causing a pulmonary embolism.
Symptoms of venous thrombosis may include:
• Swelling, pain, or tenderness in the affected limb • Warmth or redness of the skin • Palpable cord (feeling the clot under the skin) • Weakness or cramping in the affected limb
Risk factors for developing venous thrombosis include:
• Prolonged immobility or bed rest (e.g. after surgery or hospitalization) • Cancer and cancer treatment • Recent injury or trauma • History of previous blood clots or clotting disorders • Pregnancy and postpartum period • Hormone replacement therapy or birth control pills • Age over 60 • Obesity, smoking and immobilization during travel
Pulmonary Embolism
A pulmonary embolism (PE) occurs when a blood clot travels from another part of the body to an artery in the lungs. PEs are a leading cause of hospitalization and death in the United States. The clot lodges in the lungs, blocking blood flow to part of the lung tissue. This blockage can lead to respiratory failure, right-sided heart failure and even death.
Symptoms of a pulmonary embolism may include:
• Sudden severe shortness of breath • Chest pain or discomfort that worsens when you cough or take deep breaths • Coughing up blood • Feeling lightheaded or dizzy, or fainting • Rapid or irregular heartbeat • Feeling weak, anxious or confused • Coughing, wheezing and gasping for air
Atrial Fibrillation and Stroke Risk
Atrial fibrillation (AFib or Afib) is a quivering or irregular heartbeat that occurs when the upper chambers of the heart do not beat effectively. AFib increases the risk of stroke by 4-6 times. This is because the irregular heart rhythm can cause blood to pool in the atria, forming clots. If a clot breaks loose, it can travel to the brain, causing a stroke.
Symptoms of atrial fibrillation may include:
• Rapid, irregular heartbeat • Palpitations, fluttering or pounding in the chest • Shortness of breath • Weakness or fatigue • Dizziness or feeling lightheaded • Chest pain or discomfort • Confusion or memory problems
People with AFib are at increased risk of stroke, especially those over age 65. Other risk factors for stroke in AFib include:
• History of heart failure, high blood pressure, diabetes, or previous stroke • Mitral valve disease or artificial heart valve • Thyroid problems or other chronic conditions
Stroke Prevention in AFib
To prevent stroke in AFib, medications are used to control the heart rate and prevent blood clots from forming. Rate control drugs like beta blockers and calcium channel blockers can help regulate heart rhythm. Anticoagulant medications like warfarin, dabigatran, rivaroxaban and apixaban help prevent blood clots. The choice of medication depends on the patient's risk profile and other medical conditions.
Sometimes, a procedure called cardioversion may be used to restore a normal heart rhythm. In this procedure, the heart is shocked with electricity to restore a normal rhythm. Catheter ablation is another procedure that uses heat or cold to destroy the abnormal electrical pathways in the heart that cause AFib.
Prevention of Harmful Blood Clots
While some risk factors for blood clots cannot be changed, there are steps that can be taken to reduce the risk of these dangerous clots:
• Stay active - Being physically active can help prevent blood clots. Take regular breaks to walk around when traveling or sitting for long periods. • Stay hydrated - Drinking plenty of fluids can help prevent blood clots from forming. • Maintain a healthy weight - Obesity is a risk factor for blood clots. Losing weight if you are overweight can help reduce this risk. • Avoid smoking - Smoking damages the blood vessels and increases the risk of blood clots. • Get regular exercise - Regular physical activity can help reduce the risk of blood clots. • Wear compression stockings - Compression stockings can help reduce swelling and prevent blood clots from forming in the legs. • Avoid birth control pills if high risk for clots - Birth control pills can increase the risk of blood clots, especially in women who are at high risk for these clots. Alternative forms of birth control should be discussed with a doctor.
Conclusion
Blood clots that form in the veins, lungs and heart can be dangerous and life-threatening. Venous thrombosis and pulmonary embolism are serious conditions that require immediate medical attention. Atrial fibrillation greatly increases the risk of stroke, which can be prevented with appropriate treatment. By understanding the risk factors and taking steps to prevent blood clots, individuals can reduce their risk of these harmful clots. If symptoms occur, seeking prompt medical care is critical for effective treatment.
Frequently Asked Questions
Q: What is the most common location for blood clots to form? A: The most common location for blood clots to form is in the deep veins of the legs. This is called deep vein thrombosis (DVT).
Q: What is the most dangerous complication of a blood clot in the legs? A: The most dangerous complication of a blood clot in the legs is that it can break loose and travel to the lungs, causing a pulmonary embolism (PE). A PE can cause respiratory failure, heart failure and even death.
Q: What is atrial fibrillation and how does it increase stroke risk? A: Atrial fibrillation (AFib) is an irregular heartbeat that occurs when the upper chambers of the heart do not beat effectively. This irregular rhythm can cause blood to pool in the atria, forming clots. If a clot breaks loose, it can travel to the brain, causing a stroke. AFib increases the risk of stroke by 4-6 times, especially in people over age 65 or with a history of heart failure, high blood pressure, diabetes or previous stroke.
Q: How can blood clots be prevented during long-distance travel? A: During long-distance travel, blood clots can be prevented by staying hydrated, avoiding smoking, wearing compression stockings, avoiding crossing the legs, and taking regular breaks to walk around. Aspirin is not recommended for prevention of travel-related clots, but frequent leg exercises may help reduce the risk.
Q: What are the symptoms of a blood clot in the lungs? A: Symptoms of a blood clot in the lungs (pulmonary embolism) may include sudden severe shortness of breath, chest pain or discomfort that worsens when coughing or taking deep breaths, coughing up blood, feeling lightheaded or dizzy, rapid or irregular heartbeat, feeling weak, anxious or confused, and coughing, wheezing and gasping for air. If these symptoms occur, immediate medical attention is needed.
Q: How are blood clots treated? A: Treatment of blood clots depends on the location and severity of the clot. Medications include anticoagulants like heparin and warfarin to prevent further clotting, and thrombolytics to break up clots in severe cases. Compression stockings, filters, and clot retrieval devices may also be used. In some cases, surgery may be needed to remove the clot or repair damaged blood vessels.
