Delayed-type hypersensitivity reaction to foreign proteins derived from an animal serum. It occurs approximately six to twenty one days following the administration of the foreign antigen. Symptoms include fever, arthralgias, myalgias, skin eruptions, lymphadenopathy, chest pain, and dyspnea. Certain drugs (e.g., antibiotics, anticancer agents, and anti-inflammatory medications) and infectious disorders (e.g., hepatitis B) may also cause serum sickness-like reaction. [from
