Ib Tib 140mg capsule consists of the active ingredient Ibrutinib. It is indicated to treat blood cancers such as mantle cell lymphoma (MCL), chronic lymphocytic leukemia (CLL), small lymphocytic lymphoma (CLL), Waldenstrom’s macroglobulinemia, and Marginal zone lymphoma (MZL). These are cancers of the white blood cells called lymphocytes that are part of the immune system. They differ from each other by the location where the cancer occurs, the type of lymphocytes affected, and certain other factors. Ib Tib 140mg Capsule is also used to treat chronic graft versus host disease (cGvHD) after the failure of systemic therapy. During allogeneic stem cell transplantation, the patient receives stem cells from the donor. GvHD occurs when donor cells attack the patient's cells as foreign. Before taking Ib Tib 140mg Capsule, you need to talk with your physician if you have bleeding problems, infection, liver problems, heart problems, or intolerance to some sugars. This medication is not recommended for adolescents and children. It is vital to let the physician know if you have recently had or are about to have any surgical procedure.
