The most severe is our 73 year old friend who had heart attack symptoms. She ended up in the emergency room and then an additional night in the hospital. The examining doctor said the virus can attack organs and it did so to her heart. She is positive for Covid and is scheduled for regeneron infusion also. I was not aware that is given when EXPOSED not when actively ill.

Thank you so much for all the information you have provided. I appreciate the quick replies. My husband has CLL and is a patient of the Mayo Rochester. He has and continues to have wonderful care there. He was the third in line that was infected. He was the first to be prescribed Regeneron by urgent care when diagnosed as positive ( also fully vaccinated by Pfizer) He still has a cough. He feels it helped. I didn’t see that much of an improvement. I went back to urgent care 2 days later with a right nostril and right ear infection and was prescribed amoxicillin. I am into my third day of this medication. I’m not sure why we were prescribed the infusion after your information.

The U.S. Food and Drug Administration today revised the emergency use authorization (EUA) for REGEN-COV (casirivimab and imdevimab, administered together) authorizing REGEN-COV for emergency use as post-exposure prophylaxis (prevention) for COVID-19 in adults and pediatric individuals (12 years of age and older weighing at least 40 kg) who are at high risk for progression to severe COVID-19, including hospitalization or death. REGEN-COV is not authorized for pre-exposure prophylaxis to prevent COVID-19 before being exposed to the SARS-CoV-2 virus -- only after exposure to the virus. Health care providers should review the Fact Sheet for detailed information about the use of REGEN-COV for post-exposure prophylaxis.
