Office Updates

  • Penicillin (PCN) Allergy Testing is Temporarily Unavailable

    Due to a national shortage of testing materials, PCN testing is currently unavailable in our offices. We anticipate resuming tests around mid-March, pending supplier updates.

    We will update our website as more information becomes available. Thank you for your understanding.

  • Attention all Oxford/United Healthcare (UHC) patients

    Oxford/United Healthcare (UHC) began denying and/or significantly reducing our reimbursement for patients receiving allergy shots by 66-75% in 2024. UHC made these coverage changes without advance notification, and they have been unwilling to discuss any changes to our contract until at least January 2027.

    We have made every reasonable effort over the past year to resolve this with UHC, but we have not been successful. At this time, we have decided to withdraw from UHC as soon as we are allowed. Sometime after April 1, 2026, we will no longer be participating providers in the UHC network. 

    Please note that we have not made this decision lightly. Since it was founded more than 50 years ago, our practice has never dropped an insurance plan. We apologize in advance for any inconvenience this may cause. We hope that you will remain a patient in our practice. We are providing this notification now so that you will have as much time as possible if it is necessary to make alternative arrangements for your medical care.

  • 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.”

    -Pearl C., Via Google Reviews

  • “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.”

    -Charles Lee, Via Google Reviews

  • “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.”

    -Jayasudha Reddy- Joseph (Jaya), Via Google Reviews

  • “Great place. Litchman is super. Been going here for years and it could not be more convenient, well run and easy to work with for allergy shots (me and one of our younger kids all happy customers).”
