If you are using both, your healthcare provider may want to monitor your INR (a blood test that measures how long it takes your blood to clot) more closely to ensure your safety.

Always discuss any medications you are taking with your healthcare provider, including over-the-counter drugs like acetaminophen. They can help you understand any potential interactions and ensure that your treatment plan is safe and effective.
