Attention! - Patients with Cigna Commercial Insurance
We are currently renegotiating our agreement with Cigna. While discussions with Cigna continue, it is possible that our contract with Cigna will end on October 23, 2026. You may continue to see us up to October 23, 2026 with your current Cigna coverage. In the unlikely event that we do not ultimately agree on new terms with Cigna, you can still see us on an out-of-network basis; however, you may be responsible for an increased cost share. We understand that the negotiation process between doctors and insurance companies can cause patients inconvenience and stress. In most cases, however, the parties reach agreement without patient interruption. We are hopeful that will be the case here.

neffy® (epinephrine nasal spray)
Neffy (Intranasal Epinephrine) – Information Summary
Neffy has been approved for the treatment of anaphylactic reactions in patients weighing 33 pounds (15 kg) or more. It is administered as a single-dose nasal spray.
Clinical Information:
Initial approval studies were conducted in healthy volunteers.
A subsequent report including over 500 patients who used Neffy during episodes of anaphylaxis demonstrated a response rate comparable to EpiPen (approximately 90%).
Neffy produces similar increases in blood pressure, heart rate, and blood epinephrine levels as injectable formulations.
Efficacy may be reduced in patients with nasal conditions such as polyps or structural abnormalities.
Storage and Stability:
Shelf life: 2 years (longer than EpiPen)
Temperature stability: up to 120°F (49°C)
Insurance and Authorization:
Neffy may not be covered by insurance.
Due to the availability of injectable epinephrine alternatives, prior authorization will not be provided at this time.

What Our Patients Are Saying

“Awesome team! Dr. Mark Litchman is super knowledgeable on allergies, thorough and really cares about his patients. The allergy shot scheduling system is convenient and efficient and the staff is kind and caring as well. Parking is usually no problem at all. I checked in advance re: insurance so I have had zero trouble with any billing matters. I’m grateful to have help combatting these allergies, it has made a huge difference! Highly recommend this office and team.”

“Dr. Litchman figured out a protocol to treat my allergies. He also referred me to a wonderful ENT at Yale. Out of everyone I've seen in many years, he's the first M.D. to actually make an improvement in my condition.”

“My entire family sees Dr. Louit. Very knowledgeable and very good bed side manner. We are taking shots ,never had an issue, they have accommodated me even on short notice. If you take a break from your shots, you will need to start back up..it's just the way the shots work, I don't think this has anything to do with their work ethics or patient service. Overall we are very happy.”
