Rituximab infusion-related precautions include premidication with which?

Explanation:
Rituximab can cause infusion reactions during the first infusion due to rapid immune activation and release of mediators like histamine. Histamine drives symptoms such as itching, hives, flushing, and sometimes bronchospasm. Premedication with an antihistamine blocks the H1 receptor, dampening these histamine effects and making the infusion safer and more tolerable. While corticosteroids can be used in some protocols to reduce overall immune activation, antihistamines specifically address the histamine-mediated portion of the reaction. Antibiotics and antacids have no role in preventing these infusion-related symptoms.
