California health care providers can now receive free and confidential consultation on COVID-19 testing and treatment through the California Department of Public Health's COVID-19 Therapeutics Warmline.


The COVID-19 Therapeutics Warmline is available Monday through Friday, 6 a.m. – 5 p.m. Providers can call (866) 268-4322 (COVID-CA) or fill out the new online case submission form. Messages left after hours will be returned on the next business day.

Through the COVID-19 Therapeutics Warmline, health care providers of any experience level can speak with a clinician or pharmacist about drug-drug interactions or any other clinical challenges. You will only be asked to provide basic provider contact and facility information. No protected health information will be collected.
