Welcome patients of Dr. Esswein to Allergy, Asthma & Food Allergy Centers!

Dear Dr. Esswein Patients,

We are delighted to welcome you to our practice! While we did not anticipate this particularly trying time, we aim to make your transition as smooth as possible. 

If you are on allergy injections, we should now have your vials. Once we have entered your vials into our electronic system and have you registered in the practice, we will call to let you know that you can come for your injections.  Please wait for this call before you come to our office, but in the meantime, please download the new patient paperwork from this page and allergy shot treatment consent and financial consent. Email the completed new patient paperwork, consent forms, copies of the front and back of your insurance card, and driver’s license to info@aascare.com. Please include in the subject line “transferring Dr. Esswein patient”. If you have not received a phone call in the next 1-2 weeks, please call us. Please also schedule a telemedicine visit at your earliest convenience in order to become further established in our practice. You will need to have that visit before we can refill medications and answer medical questions. The first telemedicine visit will be with Dr. Esswein or one of our advanced practice providers (Lauren Davis, PA-C, Laura Kahle, PA-C, or Dani Loftus FNP-BC) so we can get you established as soon as possible. You can read more about telemedicine visits here.

  • Allergy injections are administered:
    •  8:30AM – 4:30PM Mon-Thur
    •  8:30AM – 2:30PM Fri
    • You will notice we have shot hours on Tue evenings (not currently offered during the COVID-19 pandemic) and Sat mornings. We ask that you kindly avoid these times until further notice, as they are typically our busiest times with the longest wait periods. 
  • We follow the guidelines from our professional allergy societies  that all allergy injection patients will need to wait in the office for 30 minutes after their injections.
  • During this time of concern for COVID-19, we will not escalate your dose. This is to help minimize the risk of an adverse reaction, particularly as we are now in the spring season. We will also allow you an extra week “grace period” where you will not be considered late. 

If you are on a biologic for asthma or hives (ex. Xolair, Fasenra, Nucala, Cinqair, or Dupixent), please call to schedule a telemedicine visit at your earliest convenience. This will allow us to get you registered in the practice and enable us to go through the necessary prior authorization process to obtain your medications. When you are due for your injection(s), and we have verified that we have your medication, we will schedule an in person visit in the office. Please note that our policy is that you will need an office visit for each biologic injection administered in the office. New Patient paperwork is available on this page and information on telemedicine visits is available here. Email the completed new patient paperwork, consent forms, copies of the front and back of your insurance card, and driver’s license to info@aascare.com. Please include in the subject line “transferring Dr. Esswein patient”.

For all other patients, we request that you please schedule a telemedicine visit at your earliest convenience to become established in our practice. We will need to see you for the telemedicine visit in order to refill medications or answer any medical questions. This is also an excellent time to do an annual visit. We can provide updated food allergy and asthma action plans at the time of the visit if needed. New Patient paperwork is available on this page and information on telemedicine visits is available here. Email the completed new patient paperwork, consent forms, copies of the front and back of your insurance card, and driver’s license to info@aascare.com. Please include in the subject line “transferring Dr. Esswein patient”.

We recommend that you follow us on Facebook. We will be posting practice updates, particularly as we do our best to navigate the challenges posed by COVID-19. 

It is our pleasure to play a role in keeping you well. We look forward to meeting you!


Telemedicine Services Available!

Allergy, Asthma & Food Allergy Centers has been using the doxy.me platform for telemedicine visits since Thursday, March 19, 2020, and this has been working very well for patients at all of our current locations (Swansea, Illinois; Bloomsdale/Ste. Genevieve, Missouri, and south county). Telemdicine appointments can also be done for those currently scheduled to be seen in our Chesterfield (west county) location at 16216 Baxter Rd. Suite 299, Chesterfield, MO 63017. As you know, we have moved most of our patients to telemedicine visits in the interest of public safety to decrease the spread of COVID-19 in our community while continuing to provide essential medical care.

If you are scheduled for any upcoming office visits, other than for biologic medication administration, our staff will continue to contact you before your appointment to convert your appointment to a telemedicine visit. The telemedicine visits enable new and established patients to keep their originally scheduled visits to discuss medical problems, treatment plans, allergy shots, and prescription medications while following the “stay at home” rules. These visits will be increasingly important for patients and families as the spring tree pollen season ramps up. The spring pollen season gets busy, and appointments can be scarce in the greater St. Louis area, but Allergy, Asthma & Food Allergy Centers has 8 active providers who are able to see patients via telemedicine even during these troubled times. Call 314-849-8700 or 618-233-8700 to schedule your telemedicine visit to help you stay healthy during this allergy season.

Telemedicine Frequently Asked Questions:

  1. How does telemedicine work?
    1. A staff member will call you in the morning on the day of your scheduled appointment to collect insurance information and copays.
    2. You will receive a text in most cases (an email if you cannot receive texts or prefer to do the visit using a computer/laptop/tablet) with a link from doxy.me. You can watch a brief instructional video here and/or review this document.
    3. Open the link through your phone or use Chrome browser when on a computer/laptop. You will need a strong internet connection and will need to give permission for the website to use your camera and microphone.
    4. Sign in with the patient’s first and last name and click the “Check In” box, which will place you in the virtual waiting room. You can also review the telemedicine consent and test your connection while in the waiting room.
    5. Once the visit has started, your provider will be able to see you, and you will be able to see them. Your provider may not always be looking at the camera, because they will have another screen open with your medical record so they can document and review your information. Please be assured that if the provider looks away, they are not being distracted from the visit, and your medical care is their sole focus during your appointment.
  2. Do I need to download any program or application?
    1. No, because the doxy.me platform is web-based, you can access it from a browser on an internet connected device.
  3. What type of device do I need?
    1. You need an internet connected smartphone, tablet, computer, or laptop that has a camera and microphone. You will have to give the camera and microphone permission to access your web browser, which you should be able to do in the settings of your device, and we recommend you confirm this before your appointment.
  4. What else should I do to prepare for the visit?
    1. If you have a thermometer, please take your temperature before the visit to let the provider know so they can document it in your chart.
    2. Please take your pulse manually (instructions here) or with an apple watch, fitbit, or other device before the visit and let your provider know so they can document it in your chart.
    3. You can also review the telemedicine consent form here.
  5. Is the telemedicine visit secure?
    1. Yes, the doxy.me telemedicine platform is secure and HIPAA compliant. 
  6. What if I do not receive a text or an email?
    1. If it is 5 minutes past your scheduled appointment and you have not received a text or email, please call our office.
  7. Is telemedicine more expensive than an office visit?
    1. No, you will have the same copay as you would with an in person office visit, but you do not have to leave the comfort of your home.
  8. I have read that insurance companies are waiving copays for telemedicine visits, so why do I have a copay?
    1. Insurance policies vary on this. If your insurance pays for the telemedicine visit, including the cost of the copay, you will receive a refund. You should be able to determine this by the explanation of benefits (EOB) that you will eventually receive from your insurance company.
  9. What if my primary allergist is not available for a telemedicine visit?
    1. Do not worry! Our fantastic advanced practice providers, Lauren Davis, PA-C, Laura Kahle, PA-C, or Dani Loftus, FNP-BC can see you if your primary allergist is not available.

Singulair (montelukast) Black Box Warning

On March 4, 2020 the U.S. Food & Drug Administration (FDA) decided to add a “Boxed Warning” to the oral medication montelukast (brand name, Singulair) due to an elevated concern regarding the risk of neuropsychiatric events, including suicidal thoughts and actions. Because of this new warning, the FDA is now recommending that montelukast only be used to treat patients with allergic rhinitis and asthma that do not tolerate or do not respond to alternative medications.

Montelukast is a leukotriene receptor antagonist that has been used to treat patients with asthma, allergic rhinitis and other conditions such as chronic urticaria (hives) since the drug was approved in the U.S. in 1998. There were no major reported safety concerns with this drug until 2007, when the manufacturer of Singulair updated the prescribing information and patient information to include post-marketing adverse events such as behavior/mood changes (i.e. agitation, anxiety, depression) and suicidality (suicidal thinking and behavior). 

Data collected by the FDA between 1998 and 2019 through their Adverse Event Reporting System identified 82 cases of completed suicide in patients taking montelukast, with 19 cases in patients under age 18. Interestingly, further data from the FDA’s Sentinel System collected between 2010 and 2015 did not show an increased risk of neuropsychiatric events in approximately 450,000 asthmatics older than age 6 taking montelukast vs. inhaled corticosteroids. Other observational studies also did not find an increased risk of mental health side effects. That being said, the reports of suicide along with evidence that montelukast crosses the blood-brain barrier in animal models persuaded the FDA to strengthen their warning.

Our medical providers at Allergy, Asthma & Food Allergy Centers are dedicated to providing the best possible treatment options for our patients while also keeping their safety in mind. Although the overall prevalence of severe neuropsychiatric events including suicide appears to be extremely low given the number of patients in the U.S. taking montelukast, we understand that our patients and caregivers may be hesitant to start or continue taking this medication. If you are already taking this medication it is safe to stop immediately, if you are not comfortable continuing it. However, we strongly advise that you contact our office to schedule an appointment to discuss alternative treatment options. As with any medication, either prescription or over-the-counter, we are more than happy to discuss the risks and benefits with you. If you are not having any problems while on montelukast, it is likely safe to continue the medication.
