Hemoptysis treatment focuses on addressing the underlying cause of coughing up blood. If caused by an infection, antibiotics or antiviral medications may be prescribed. For conditions like bronchiectasis or lung cancer, treatment may include antibiotics, cough suppressants, or surgical intervention. In severe cases, embolization (blocking blood vessels) or surgical removal of the affected lung tissue may be required to control bleeding. The treatment plan depends on the severity of the hemoptysis and its underlying cause.
