Serious side effects of Xarelto include: 1  Severe bleeding. 2  Hepatitis. 3  Decreased platelets.  Allergic 1  reactions. Stevens-Johnson syndrome.
Xarelto reversibly binds Xa and does not deplete it. It has a plasma half-life of 5 to 9 hours in healthy subjects (ages 20 to 45 years) and 11 to 13 hours in the elderly. Therefore, the anticoagulant effect is only present when the drug is taken.
