Regular INR monitoring is key to safe Coumadin therapy. Aim for testing every 1-4 weeks, or more frequently as your doctor directs, depending on your individual needs and stability.
Factors Affecting INR Variability
- Dietary changes: Significant increases or decreases in Vitamin K intake (green leafy vegetables, certain oils) directly impact INR. Medication interactions: Many medications, including antibiotics and antifungals, can alter Coumadin’s effectiveness. Illness and Alcohol consumption: Both illness and alcohol can influence INR, necessitating more frequent monitoring during such periods.
Consistent monitoring prevents both over – and under-anticoagulation. An INR outside your target range poses serious risks.
Consequences of Inconsistent Monitoring
High INR (over-anticoagulation): Increases bleeding risk, potentially leading to dangerous internal bleeding or stroke. Low INR (under-anticoagulation): Raises the risk of blood clots forming, which can cause heart attack, stroke, or pulmonary embolism.
Partner with your healthcare provider to create a monitoring schedule that fits your lifestyle and risk factors. Discuss any concerns immediately. Proactive management protects your health.
