Update: Allergen Immunotherapy During the COVID-19 Outbreak

Like many, we are carefully evaluating any activity that might increase the risk of exposure to the COVID-19 virus for our patients. Under these extraordinary but hopefully temporary circumstances our office is making the following modifications to the allergy immunotherapy administration schedule for the months of March and April. These temporary changes will have minimal impact on your immunotherapy progress but will significantly reduce the risk of transmission of the virus through social contact.

  • If you are receiving maintenance allergy injections every 2-4 weeks, no change in schedule is needed.
  • If you are on a build-up schedule and receiving injections at least weekly, come in for your injection(s) every 2-4 weeks.
  • No downward dose adjustment will be needed as long as you come in at least once every four weeks.
  • All patients coming in for an allergy injection will be asked about recent travel, potential exposure to the COVID-19 virus, and recent respiratory symptoms and will have their temperature checked.

Please do not come to the office if you have a fever or suspect that you have been exposed; call our office first.

If you have any questions, please call 480-705-8844 or email:

Coronavirus Update

As the global and local effect of coronavirus (COVID-19) continues to evolve, our practice is firmly committed to the health and safety of our patients. We are closely monitoring the changing situation and complying with recommendations from the CDC and The Arizona Health Department.    In addition, we are implementing the following change to our usual operating procedures:                                

Before Coming to the Office

  • If you have had a fever (temperature above 100) within the past week, do not come to the office. Call our office for further instructions.


  • All patients and family members coming to our office will be asked about symptoms, travel, contacts, and have their temperature checked before entering the office.

Social Distancing

  • We will limit the number of patients in our waiting room at any given time to 10.
  • We ask that no more than 2 family members accompany a patient into the office.
  • To minimize the time in the waiting room, all patients with an appointment to see the doctor will be taken immediately to an exam room after checking in.


  • To reduce the need for travel and visits to the office, we are now offering secure, video-based appointments with Dr. Millhollon
  • Weekend and evening appointments are available
  • Please call our office for more information.

Allergy Immunotherapy and Biologic Injections

  • After the initial screening, patients will go to the injection room as usual
  • After your injection, you may wait in the courtyard or waiting room with the goal of maintaining at least 6 feet from any other patient with no more than 10 patients in the waiting room.
  • After your wait time, you may come to the outside window to have your arm checked and indicate that all is well before leaving.

Stay Healthy

At this time, the risk of serious illness from coronavirus infection in Arizona is small. However, the risk is greater for some groups including the elderly and those with chronic health problems including asthma and immunodeficiency.

Like all viral respiratory infections, Covid -19 can trigger an asthma attack. Keeping your asthma under good control should, therefore, be a high priority – as always but particularly at this time. This includes taking your preventative medications daily as prescribed, reviewing your asthma action plan, and making sure all medications are available and up-to-date. Patients who take oral steroids such as prednisone daily are also at increased risk. These high-risk groups need to be particularly vigilant about virus avoidance measures such as regular hand washing and avoiding unnecessary exposure to large groups of people.

If you have any questions, please do not hesitate to contact us.
