MabThera injections are used to treat various types of cancer, such as chronic lymphocytic leukemia and chronic lymphocytic leukemia. They are also used to treat certain immune-mediated diseases, such as rheumatoid arthritis and vasculitis. MabThera contains an active ingredient called rituximab, which targets B cells in the immune system, helping to reduce inflammation and inhibit the growth of harmful cells. The drug is given intravenously and must be under close medical supervision in a hospital or equipped medical center due to the possibility of allergic reactions in some patients. It is important to monitor vital signs and blood tests during treatment to avoid complications such as decreased immunity or respiratory problems. MabThera is a powerful drug used in a long-term treatment plan that requires continuous monitoring by a specialized medical team.
