ED Interventions included: Medications: LORazepam (ATMAN) injection 1 mg (has no administration in time range); LORazepam (ATIVAN) 2 mg/ml- injection -ADS; Override Pull (override Pull 05Jan2021 09:19); diphenhydramine (BENADRYL) 50 mg/mL; injection -ADS Override Pull (Override Pull 05Jan2021 09:20); Lorazepam (ATIVAN) injection 2 mg (2 mg Intravenous Given 05Jan2021 09:00); diphenhydramine (BENADRYL) injection 50 mg (50 mg Intravenous Given 05Jan2021 09:00); 0.9% sodium chloride (NaCl) 1,000 mL bolus (Intravenous Completed 05Jan2021 11:00); lactated ringers (LR) IV 500 mL (0 mLs Intravenous Completed 05Jan2021 12:02); potassium bicarbonate (K-LYTE) 25 MEQ disintegrating tablet 25 mEq (25 mEq Oral Given 05Jan2021 12:01).; Sender's Comments: There is a reasonable possibility that the events dizziness, nausea, vomiting, syncope, anaphylactic reaction, headache, chills, and fatigue were related to BNT162b2 based on known drug safety profile. Based on the temporal relationship, the association between the other events with BNT162b2 can not be fully excluded.  The impact of this report on the benefit/risk profile of the Pfizer product is evaluated as part of Pfizer procedures for safety evaluation, including the review and analysis of aggregate data for adverse events. Any safety concern identified as part of this review, as well as any appropriate action in response, will be promptly notified to regulatory authorities, Ethics Committees, and Investigators, as appropriate.
