Following a review of the literature, the CDC and NIOSH recommendations determined that Rituximab is not a dangerous medicine and has no adverse health consequences when it comes into contact with the eyes, skin, or mucous membranes (Genentech, 2011). However, because this drug can cause serious side effects, it is important to know how to use it safely. The National Institute for Occupational Safety and Health (NIOSH) reviewed available data on occupational exposures to Rituximab and concluded that it is not likely to be harmful if proper protective measures are taken. Rituximab is the name of the medication product used to treat certain types of cancer. It works by destroying B cells, which play an important role in immune response. By removing B cells, the body's defense mechanism is weakened and patients become more vulnerable to infection. Healthy tissues usually protect themselves from toxic substances in the environment by clearing them out of the body quickly. However, because B cells are found in many different parts of the body, including the bone marrow, lungs, and brain, killing them using Rituximab could have severe side effects. Patients who take this drug should be closely monitored by their doctors during treatment and for some time after they stop taking it.
