What is listed as an alternative to epinephrine 1 mg in allergic reactions?

• A. EpiPen
• B. Saline infusion
• C. Diphenhydramine only
• D. Oxygen therapy only

Answer: (A)

Epinephrine is the first-line treatment for allergic reactions and anaphylaxis because it rapidly reverses the key life-threatening features: airway swelling, bronchospasm, and low blood pressure. An EpiPen is an epinephrine auto-injector, providing a quick, pre-measured dose of the drug that can be used immediately by a patient, caregiver, or bystander. This makes it a practical alternative to a manual injection in an emergency, ensuring timely administration when medical help may not arrive right away.

Saline infusion, while supportive for circulation, does not address the underlying allergic reaction. Diphenhydramine can help with itching and hives but does not prevent airway compromise or shock. Oxygen therapy supports breathing but does not treat the cause of the reaction. So the option that best fits as an alternative means of delivering the essential treatment is the epinephrine auto-injector.
