What are the contraindications for epinephrine when indicated?

• A. None when indicated
• B. Hypotension
• C. Pregnancy
• D. Pediatrics intolerance

Answer: (A)

In this context, key point: epinephrine is the life-saving first-line treatment for severe allergic reactions and anaphylaxis, so when it is clearly indicated there are effectively no contraindications to give it. The risks of not treating a life-threatening reaction far outweigh potential downsides, so the benefit justifies administration.

Epinephrine works by constricting blood vessels to raise blood pressure, reducing swelling in the airway, and relaxing airway smooth muscle to improve breathing. Those actions directly counter the dangerous symptoms of anaphylaxis, making withholding it unacceptable in an emergency.

The choices listed aren’t prohibitive in this scenario. Low blood pressure is part of the reaction you’re treating, not a reason to withhold epinephrine. Pregnancy is not a contraindication; epinephrine is used for anaphylaxis in pregnant patients. Pediatric intolerance isn’t a recognized barrier to giving it, since there are established pediatric dosing guidelines and it remains the standard of care for children with anaphylaxis. Therefore, there are none when it is indicated.
