What should a pharmacist do if a patient experiences a severe allergic reaction post-vaccination?

• A. Administer antihistamines and monitor the patient
• B. Administer epinephrine and call emergency services
• C. Provide reassurance and schedule a follow-up
• D. Contact the patient's primary care physician

Answer: (B)

If a patient experiences a severe allergic reaction after vaccination, administering epinephrine and calling emergency services is the appropriate course of action. Severe allergic reactions, known as anaphylaxis, can escalate rapidly and pose serious threats to the patient’s life. The immediate use of epinephrine is critical because it counteracts the effects of anaphylaxis by opening the airways, stabilizing blood pressure, and slowing down the progression of the allergic response. Calling emergency services ensures that the patient receives timely advanced medical care, which may include additional treatments such as oxygen, intravenous fluids, and further medication. After administering epinephrine, continuous monitoring of the patient is also essential while waiting for emergency responders, as symptoms may recur and additional treatment may be necessary. Other responses, such as administering antihistamines, providing reassurance, or contacting a primary care physician, do not address the urgency and severity of anaphylactic reactions. Antihistamines are not sufficient alone for treatment in such cases, reassurance may delay urgent care, and while contacting a physician can be part of follow-up care, it is not a suitable immediate response in an emergency.
