Medical literature overwhelmingly confirms that Epi-pens are designed to deliver epinephrine specifically as the primary emergency treatment for severe allergic reactions and anaphylaxis.
The retrieved papers consistently state that epinephrine is the first-line treatment for severe allergic reactions (anaphylaxis) and that Epi-Pens (epinephrine auto-injectors) are specifically engineered and prescribed for this exact purpose. No papers refute this fundamental medical fact.
