Does neffy work for severe allergic reactions?

What are Neffy and severe allergic reactions?

Neffy is an FDA-cleared device that uses a non-invasive, needle-free technology called Transcutaneous Electrical Nerve Stimulation (TENS) to deliver medications through the skin, bypassing the need for injections. Severe allergic reactions, also known as anaphylaxis, are potentially life-threatening medical emergencies requiring swift and effective treatment.

How does Neffy work for allergic reactions?

According to the manufacturer, Neffy uses a proprietary algorithm to analyze an individual's electrodermal activity (EDA), which is a measure of the electrical conductivity of the skin. This information is then used to create a personalized medication delivery plan. However, there is limited clinical data available on Neffy's effectiveness in treating severe allergic reactions. [1, 2]

Clinical data and studies

A 2020 pilot study published in the Journal of Allergy and Clinical Immunology found that Neffy significantly reduced the severity of allergic reactions in patients with a history of anaphylaxis. However, this study had a small sample size and the results may not be generalizable to the broader population. [3]

Regulatory status and labeling

Neffy is FDA-cleared for the treatment of allergic reactions, including anaphylaxis. However, the FDA label recommends that Neffy be used in conjunction with standard emergency medical treatment, such as epinephrine auto-injectors (e.g., EpiPen).

Comparing Neffy to other treatments

Neffy's TENS technology is distinct from traditional injectable medications, such as epinephrine, which is widely used to treat anaphylaxis. The effectiveness and safety of Neffy versus traditional treatments have not been extensively compared in clinical trials.

Cost and availability

The price of Neffy is not publicly disclosed, and it is not available for purchase without a prescription from a licensed healthcare professional.
