Melatonin 20mg 3x daily and 40g before sleep does help(and it's over the counter). I don't know if ivermectin will be of much help at this late of a stage, and I'm no lawyer by any means but you could have a lawyer from America's Frontline doctors help you draft a strong letter to the hospital to get them to act, there is legislation such as "Right to try" which can help your case. Also definitely try monoclonal antibodies. That is EUA approved I believe. I pray your sister is going to be okay. My aunt and uncle died from hospital terrible practices with covid. It's terrible, but hospitals are killing people more than the virus. I'm sorry to hear what's happening to your family:(
