I took Paxlovid and my doc did the same thing (short term cessation of Crestor). Frankly, I didn’t notice that it did any good (it still felt like the flu for 3 days and was then gone), but the Paxlovid has a side effect that makes your mouth taste like you swallowed a large bag of trash. Just gross.
My wife said she got a very bitter taste. She overcame it by sucking on very strong cough drops.
