Furosemide has been on all along, had been cutting back last 4 months per doctor's orders. Losartan has been on from the beginning, about the last 2 and a half years. Pantoprazole has been taking the last 4 years. The husband believes Rosuvastatin is for diabetes or whatever but, patient is not diabetic. Carvedilol has been taking a little more than a year. Was on another blood pressure medicine. Calcium Citrate/Vitamin D has been taking the last 2 and half years. Patient's husband reported for his wife (patient) who is a transplant recipient from 2 and a half years ago. She has also had Covid twice in the last 2 years. The last 2 boosters she has gotten knocked her out for like 5 days and had been running fevers. Talked to the cardiologist and transplant doctor and got a message out to them this morning. Patient got the shots Sunday (23Oct2022) at 3:30PM. Within 10 hours or so, 8 or 10 hours, she just got knocked out, turns fever, had body aches, sleeping a lot and won't eat (Oct2022). Was not sure of anything, as her husband and caregiver, was trying to figure something out, if there was something they need to do for the next booster. This is her fifth vaccine shot in the last 2 years. Yesterday (24Oct2022), she was running a fever and slept all day, had been asleep all day yesterday and today (25Oct2022). Got some food down and a lot of water. Was not saying this is the Covid vaccine doing this but the one she had Sunday, and Aug2022, when she got the fourth booster, it happened the same way. Clarified this occurred after the last 2 boosters. Sunday, 23Oct2022, had the third booster and within 10 hours, she was running a high fever, 102.7 being the highest. Patient tried eating and her husband would have to force her to eat. The husband is still getting annoyed that the cardiologist hasn't called him back yet. The husband is concerned and and does not want this to happen again. He wondered if this is possibly because of the Covid vaccine. The husband highlighted knocked out for 5 days, running fevers as serious.   No follow-up attempts are possible.
