Hi Doctor, my aunt has been tested positive for covid around 10 days back. Initially she was doing ok but then her oxygen level suddenly started going below 80. We got her admitted in a hospital. During this period, she got 4 doses of remedesivir. But now the doctor is saying that they need to give her a dose of tocilizumab injection. I tried to read some articles on the injection and found that it has quite a lot side effects. Can you please let me.know if Is this injection is safe for her or not.
