Fever is driven by prostaglandin E2 in the hypothalamus, which raises the body’s temperature set point in response to pyrogens. Fever-reducing drugs work by lowering that set point, typically by inhibiting cyclooxygenase and reducing prostaglandin synthesis, or by acting centrally to reset the hypothalamic thermostat. This makes the term antipyretic the right label, since it specifically means fever-reducing. The other options fit different roles: antihistamines block H1 receptors to relieve allergic symptoms, decongestants relieve nasal congestion by vasoconstriction, and antineoplastics target cancer cells.
