I have been taking xarelto for about three years. Before that I took pradaxa. Several months ago I started itching. First it was my head, but now my whole body itches, especially in the evenings. I worried about lice, but that is not the case. I have purchased various products to use on my bed, etc. , but the itching continues with fine bumps. Then I remember that my sister complained of itching when she took Xarelto for a short time. She stopped taking it. I have a pace maker and afib. Can the xarelto be the cause?
