NOTICE OF CHANGE IN PROCEDURE FOR ALLERGY IMMUNOTHERAPY

San Francisco Allergy, Asthma & Immunology is resuming our Allergy Shot Clinics.

To limit the spread of coronavirus and to optimize social distancing, our offices will be scheduling injections BY APPOINTMENT ONLY. Please call us to schedule your appointment today.

Please follow these required precautions during your visits to protect yourself, our staff, and other patients:

Wear a cloth mask throughout your visit.
Do not come to our office if you or someone in your home has any of the following: fever over 100 F, cough, difficulty breathing, loss of smell, or contact with a known or suspected COVID patient.
Do not bring other family or companions to your appointment. If your child is receiving injections, please have only one parent or caregiver with them.
30-minute wait period following your injection is still mandatory, but will be spent in a private exam room, not a shared waiting area.

We thank each one of you for your cooperation and commend your efforts to keep our community safe.

Thank you,
San Francisco Allergy, Asthma & Immunology
