Thanks to a generous program by ARS Pharmaceuticals, qualifying K-12 schools can receive two free cartons (four single dose devices) of neffy nasal epinephrine spray at no cost. ARS' neffy device is a needle-free epinephrine for use in the emergency treatment of severe allergic reaction, known as anaphylaxis. Anaphylaxis is a life-threatening situation that can result in hospitalization or fatality.
