Question 1

What is Neffy?

Accepted Answer

Neffy is a formulation of epinephrine designed to quickly reverse the symptoms of a severe allergic reaction. It works by relaxing the muscles in the airways and tightening the blood vessels to improve breathing and blood pressure.

This medication is intended for immediate use during a systemic allergic response. It serves as an alternative to traditional epinephrine delivery methods for managing medical emergencies.

Question 2

What is Neffy used for?

Accepted Answer

Neffy is used to treat emergency treatment of allergic reactions including anaphylaxis .

Question 3

How does Neffy work?

Accepted Answer

Mechanism of Action

Neffy contains epinephrine, a medication that acts as a sympathomimetic agent. This means it mimics the effects of naturally occurring chemicals in the body that respond to stress or danger. When administered during a severe allergic reaction (anaphylaxis), it works rapidly on several systems to stabilize the body.

Improving Breathing and Blood Pressure

Epinephrine targets specific receptors throughout the body to counteract the symptoms of anaphylaxis:

Alpha-adrenergic receptors: It causes blood vessels to constrict (narrow). This helps to increase blood pressure, which often drops dangerously during a severe reaction, and reduces swelling in the face, throat, and tongue.

Beta-adrenergic receptors: It relaxes the muscles in the airways, allowing the lungs to open up so the person can breathe more easily. It also stimulates the heart to beat faster and more strongly.

Stopping the Allergic Response

In addition to treating symptoms, epinephrine helps stop the reaction from progressing. It prevents certain immune cells, known as mast cells and basophils, from releasing more histamine and other inflammatory chemicals into the bloodstream.

Nasal Delivery

Unlike traditional epinephrine treatments that require an injection into the muscle, Neffy is absorbed through the lining of the nose (nasal mucosa). Once sprayed into the nostril, the medication enters the blood vessels in the nasal passage to provide systemic relief throughout the body.

Question 4

What are the active ingredients in Neffy?

Accepted Answer

The active ingredient in Neffy is epinephrine .

Question 5

What are the side effects of Neffy?

Accepted Answer

Common side effects of Neffy may include:

Nasal discomfort

Headache

Nausea

Always consult with a healthcare professional about potential side effects.

Question 6

What drug class is Neffy?

Accepted Answer

Neffy belongs to the progestin-only contraceptive drug class.

Question 7

What is the dosage of Neffy and how do I take it?

Accepted Answer

Neffy is for use in the nose only. It is a single-use device that should not be tested or primed before use, as doing so will waste the medication. To administer the dose, insert the tip of the device into one nostril and press the plunger firmly.

Administration Steps

Ensure the person is lying on their back or sitting up.

Insert the nozzle into one nostril.

Press the plunger to deliver the full dose.

Seek emergency medical help immediately after administration, even if symptoms improve.

Additional Doses

If symptoms do not improve or if they get worse after the first dose, a second dose may be administered. Use a new, unopened device for the second dose. This second dose should be sprayed into the same nostril used for the first dose.

Question 8

Is Neffy safe during pregnancy and breastfeeding?

Accepted Answer

Pregnancy

Epinephrine is the standard first-line treatment for life-threatening allergic reactions (anaphylaxis) during pregnancy. Anaphylaxis is a medical emergency that can result in death or serious harm to both the pregnant person and the fetus if left untreated. Because of these risks, the benefits of using Neffy during an emergency typically outweigh the potential risks of the medication.

There are no adequate or well-controlled clinical studies specifically looking at the use of nasal epinephrine in pregnant women. If you are pregnant or planning to become pregnant, you should discuss the use of this medication with your healthcare provider as part of your allergy management plan.

Breastfeeding

It is currently unknown whether epinephrine administered via nasal spray passes into human breast milk. However, epinephrine is a hormone that occurs naturally in the body and has very low oral bioavailability, meaning it is not easily absorbed through the digestive system. You should consult with a healthcare professional if you have concerns about using Neffy while breastfeeding.

Question 9

What forms and strengths does Neffy come in?

Accepted Answer

Neffy is provided as a nasal spray. This medication is administered using a needle-free delivery device designed for use in the nose.

Nasal Spray: The medication is contained in a device intended for a single use. Each device is designed to deliver a dose into a nostril during an emergency.

Question 10

What is the FDA approval status of Neffy?

Accepted Answer

FDA Approval History

The U.S. Food and Drug Administration (FDA) approved Neffy on August 9, 2024. This approval marked a significant milestone as it is the first epinephrine product for the treatment of anaphylaxis that is administered as a nasal spray rather than by injection.

Approved Indications

Neffy is indicated for the emergency treatment of Type I allergic reactions, including life-threatening anaphylaxis, in adults and pediatric patients who weigh at least 30 kg (approximately 66 pounds).

Regulatory Background

The FDA granted Neffy Fast Track designation during its development to expedite the review of the medication. The approval was based on clinical studies that compared the concentration of epinephrine in the blood after nasal administration to traditional injection methods. These studies demonstrated that the nasal spray provides comparable levels of the medication to help reverse the symptoms of a severe allergic reaction.

There are currently no Boxed Warnings or Risk Evaluation and Mitigation Strategies (REMS) associated with this medication.

Question 11

What should I know about Neffy and cost?

Accepted Answer

Estimated Costs

The manufacturer's list price for a two-pack of Neffy is approximately $710. However, the amount a patient actually pays at the pharmacy is typically lower depending on their insurance plan and available financial assistance.

Insurance and Savings Programs

Commercial Insurance: Patients with private or commercial insurance may qualify for a co-pay savings program that reduces the cost to as little as $25 for a two-pack.

Uninsured or High-Deductible Plans: For individuals without insurance or those whose insurance does not cover the drug, the manufacturer offers programs such as neffyConnect, which may provide the two-pack for a discounted price of approximately $199.

Factors Influencing Price

Neffy is generally sold as a two-pack because a second dose may be necessary if symptoms of a severe allergic reaction do not improve after the first administration. The final out-of-pocket cost can be affected by:

Your specific insurance provider's formulary and tier placement.

Eligibility for patient assistance programs.

The specific pharmacy used to fill the prescription.

It is recommended to check with your insurance provider or the manufacturer for the most current pricing and to determine which savings programs you may be eligible for.
