    Riastap can cause blood clots. Your doctor will monitor you for blood clots while you are receiving Riastap. In addition, contact your doctor immediately if you experience lung, chest, or leg pain, coughing up blood, difficulty breathing, rapid breathing, or other unexplained symptoms.

    Riastap is made from human plasma (part of the blood) and may contain infectious agents (such as viruses) that can cause disease. The risk of infection, however, has been reduced by screening plasma donors, by testing the donated plasma for certain infections, and by a process to inactivate and/or remove certain viruses during manufacturing. Tell your doctor immediately if you experience headache, fever, nausea, vomiting, weakness, feeling tired, diarrhea, or yellowing of your skin or whites of your eyes.
