Acetaminophen and diphenhydramine as premedication for platelet transfusions: a prospective randomized double-blind placebo-controlled trial.
Non-hemolytic transfusion reactions (NHTR) occur in up to 30% of patients receiving platelet transfusions. Premedication with acetaminophen and diphenhydramine is a common strategy to prevent NHTR, but its efficacy has not been studied. In this prospective trial, transfusions in patients receiving pre-storage leukocyte-reduced single-donor apheresis platelets (SDP) were randomized to premedication with either acetaminophen 650 mg PO and diphenhydramine 25 mg IV, or placebo. Fifty-one patients received 98 transfusions. Thirteen patients had 15 NHTR: 15.4% (8/52) in the treatment arm and 15.2% (7/46) in the placebo arm. Premedication prior to transfusion of pre-storage leukocyte reduced SDP does not significantly lower the incidence of NHTR as compared to placebo.
