Patient Education

Talc Intrapleural


Talc is used to prevent malignant pleural effusion (buildup of fluid in the chest cavity in people who have cancer or other serious illnesses) in people who have already had this condition. Talc is in a class of medications called sclerosing agents. It works by irritating the lining of the chest cavity so that the cavity closes and there is no space for fluid.
