Richmond University Medical Center is suspending monoclonal antibody treatments for COVID-19, effective December 23.

Recently released, medically reviewed findings from the New York City Department of Health and Mental Hygiene (NYC DOHMH) have concluded that current monoclonal antibody treatments are not effective in treating illness caused by the omicron variant. Omicron now accounts for over 90 percent of COVID-19 cases in New York State. RUMC, along with many healthcare facilities across New York City, is suspending treatments based on this evidence. Once newer, more effective treatments for COVID-19 are available, or more information is available, we will inform the community.

If you have been diagnosed with COVID-19, please contact your primary care doctor for next steps.
