Question: xarelto how long to take?
Answer: How long you need to take rivaroxaban will depend on why you're taking it. If you have had an operation to replace your knee or hip joint, you'll probably take rivaroxaban for 2 to 5 weeks. If you have had a blood clot (DVT or pulmonary embolism), you'll normally take rivaroxaban for at least 3 months.
