Common causes of pleurisy include trauma, postcardiac injury, infection (i.e., viral, bacterial, or parasitic), respiratory illness, caustic exposure (i.e., drug-induced), autoimmune disease, and malignancy (TABLE 1).
In order to treat your pleurisy the right way, your doctor first must find out whatâs causing it: 1  If itâs bacteria, antibiotics can make you better. 2  If itâs a fungus, heâll likely prescribe an antifungal drug. 3  If itâs a virus, youâll improve without the help of drugs.
