A blood clot in the brain can cause a. stroke. Rivaroxaban lowers the chance. of clots forming and causing a stroke. Rivaroxaban is also used to treat clots that have already formed in the. veins of your legs (deep vein thrombosis) , or in your lungs (pulmonary. embolism), and to lower the risk of clots forming again.actor Xa is the clotting factor that rivaroxaban blocks. This prevents the clot from forming. Rivaroxaban can help stop clots from forming and can keep clots from getting larger, but it does not break up clots that are there already.
Treatment usually lasts three months and involves taking rivaroxaban twice a day for the first 21 days and then once a day until the end of the course. Read the NICE guidance about rivaroxaban for the treatment and prevention of recurrent deep vein thrombosis and pulmonary embolism.
