I had heard this as well, but apparently it’s not true. When my wife first got sick we both took a covid test and it came up negative, but when she went to the hospital they were positive that she actually had it and the first couple tests were false negatives. (She ended up having 6 total tests over five days, I had two)
The doctor originally told us to keep her on Tylenol to control the fever, I asked about nsaid danger and she said it was not an issue. I asked again later that week when she had to go to the ER because of fever. Again they told us to keep up on the maximum dose of Tylenol all day, again I asked about nsaids and possible complications if it was Covid but he was not worried what so ever.
And finally when she was admitted to the ICU and they were absolutely sure it was going to be Covid (they just kept testing her thinking it was going to show positive at some point) I told the infectious disease doctor my concerns and how much tylenol she had had over the week and again, they were not worried at all.
Things change daily with this damn virus, but I can tell you that at the very least the doctors up here in the pacific nw are not worried about nsaid and Covid in the least bit and encourage the max daily dosage to control fever.
(side note: I don’t know if any of you listen to podcasts, and more specifically Dan Cummins Time Suck, but he just did an episode on the Columbine massacre and he starts the episode talking about his friend that has Covid and the symptoms he had, they are weird and scary. It’s crazy the way this virus is affecting different people different ways and how it’s mutating over this short time. F*!k this virus.)
