What is Neffy?

• A. An intranasal treatment for anaphylaxis
• B. A topical antihistamine
• C. A sublingual immunotherapy
• D. A transdermal patch for allergies

Answer: (A)

Neffy is an intranasal epinephrine spray approved for emergency treatment of anaphylaxis. The nasal route allows rapid, needle-free delivery of epinephrine, making it possible for a caregiver or the patient to administer it quickly during a severe allergic reaction. Epinephrine is the first-line therapy for anaphylaxis because it rapidly reverses airway edema, increases blood pressure, and reduces bronchoconstriction, addressing the life-threatening aspects of the reaction. This is why Neffy fits as an intranasal treatment for anaphylaxis.

In contrast, a topical antihistamine would only address local symptoms like itching or redness and would not treat the systemic components of anaphylaxis. Sublingual immunotherapy is a long-term allergy-desensitization approach, not an acute rescue treatment. A transdermal patch provides continuous drug delivery over time and is not used for urgent management of anaphylaxis. After using Neffy, seek emergency medical care, as symptoms can progress or recur.
