Good Morning @hello1234
Wow, I sure admire you, taking care of your elderly parents! You have a lot on your plate!
Did the nausea just start after being diagnosed with Covid? Maybe it is related to Covid? I have had some nausea issues prior and post transplant. Sometimes it helps to eat a little something if I have an empty stomach, especially if I have taken my meds. Even drinking something other than water can help like cold 7-Up. Like @gingerw stated, I have experienced that Ondansetron or Zofran can shut down your gut. I still may take this very occasionally like when I need to be fasting for a long time like at Mayo on the day of my labs and kidney biopsy. In the 1st month after transplant when my tx meds were a higher dosage the Ondansetron didn’t completely shut things down, and I took it sometimes on days I needed labs drawn. Like you, I worry about keeping my tx meds down. Can you get any help taking care of your parents so you can rest considering you are recovering from Covid yourself? Did they get the monoclonal antibodies, too?
