He started Paxlovid night of 18May2022. Before caller gave the patient the Paxlovid she put a call into the cardiologist that was on call for his practice. She also put a call into the oncology group but had trouble getting through to them. She was not 100% on board with him starting Paxlovid. She is hydrating the patient like crazy. He is having side effects from the Paxlovid and she wanted to call Pfizer and verify that his side effects are normal, to make sure he is ok.  Side effects: He is complaining of a very bad taste in his mouth that nothing seems to be getting rid of. Since it did start just since he took his doses of the Paxlovid she thinks it is definitely related to the Paxlovid. She has been giving lollipops, ginger hard candies to suck on, but nothing is removing that taste. Now when he peed his pee is tinged with pink which is alarming to her. She just pushed on him another energy drink for him to drink. He is walking around and she wants him not walking around. He is very irritable, but she does not know if that is just from COVID and being home or not. She knows there are renal concerns with Paxlovid so that is what is alarming her.
