Additional Information:  Registered nurse and the patient herself calling about Paxlovid and the metallic taste in the mouth and she mentioned she has had four total Pfizer Covid19 vaccines with the last one being the bivalent vaccine on 08Nov2022, and she did still contract the virus, tested positive on Tuesday morning. Patient details: Height is 5 feet 2.5 inches and weight is from today and is 125.2 pounds and that is her weight since she is not eating and is low weight and is doing chicken broth. Had the first dose of Paxlovid this morning and could already taste it and as she is talking it is almost like wanting to avoid breathing as she can smell it and taste it and is hardly inhaling and she wants to avoid it when she does not breathe deeply. The taste after taking Paxlovid began probably not until about 1:30pm or 2:30pm and she began taking Paxlovid at 11:00am today; sensed it around 1 or 1:30 and was tasting it and then the breathing the taste came into play before that she was tasting it. Regarding the taste, her first inclination is to say it is not medically significant but losing one's sense of taste if it became permanent would be highly significant and the only other reason she would say this is medically significant is because for her if she is not breathing to avoid it, the taste and smell because of speaking, she would stop taking it and this is telling her something is wrong because one should avoid it; states she is self isolating. She has to turn on the light regarding finding her Paxlovid and then states she was just looking around for it and turning on the light is not in regard to reading the package: for Paxlovid she sees the SN number and then states hang on she can't read it and then clarified to state the evening doses are three tablets each and the Nirmatrelvir is 150mg each and the Ritonavir is 100mg and she started taking it today. Not sure what she is going to do regarding continuing to take the Paxlovid and she can override the taste of it and not feeling like she wants to. Pfizer Covid Vaccine: 1st dose administered on 20Feb2021 with lot EN6198 to left upper arm left deltoid and she was asked but did not state dosage; patient card does not have expiry dates or NDC numbers written on it; 2nd dose administered on 12Mar2021 with lot EN6208 to left deltoid; 3rd dose administered on 28Sep2021 with lot 301358A to left deltoid; 4th dose clarified to being administered on 07Nov2022 and this was the bivalent dose with lot GH9693 to left deltoid. After the 2nd covid vaccine she noticed her left armpit swelling and read that was happening so that is why all subsequent ones she does on her left arm, and it just feels different under her arm now and is swollen; her doctor sent her for an ultrasound, and nothing was detected as amiss but the swelling is ongoing now and is squishy and feels different than the other side. The ultrasound as nothing swollen for nodes or lymph nodes at that time and she does not remember when the ultrasound was but it was probably a couple of months after the doses of vaccine. For being diagnosed with covid and the armpit swelling after the covid vaccines, states it is medically significant because people want to get treatment if it is discerned to being enlarged lymph nodes or breast cancer and it is important to get these statistics. Tested positive for covid on 29Nov2022; had throat symptoms of scratchiness on November 26th and went to bed; caller clarified that date as November when the throat scratchiness occurred and states with covid, she is mixed up with her brain being weird; November 27th, thought she was feeling a little strange in her throat and tested and had symptoms but the test was negative and thought she just had a cold; when the sore throat got worse worse worse, on Tuesday morning she thought something else was going on and tested positive on Tuesday 29Nov2022. The night of the 26th on Saturday she got something that felt weird with the throat and Sunday something was happening. Had no treatment for the reported event but just had the ultrasound for the arm swelling after the first two vaccines and that was it just to make sure that it was not cancerous lumps. She is supposed to take Paxlovid six tablets a day for five days. Retired now but used to work in clinical trials and used to have to collect information all the time and volunteered at the vaccine clinics there and that was fun. Asked for the safety report number is it for central watch reports in reports that go out to different studies if a doctor filled out the information or is it a Pfizer reference number.
