Q: How does Neffy work?

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.

Q: What are the active ingredients in Neffy?

The active ingredient in Neffy is epinephrine .

Q: What are the side effects of Neffy?

Common side effects of Neffy may include: Nasal discomfort Headache Nausea Always consult with a healthcare professional about potential side effects.

Q: What drug class is Neffy?

Neffy belongs to the progestin-only contraceptive drug class.

Q: Is Neffy safe during pregnancy and breastfeeding?

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.

Q: What is the FDA approval status of Neffy?

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 1

What is Neffy?

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.
