Additional information: She was asking if Paxlovid and Pfizer Covid Vaccine Comirnaty 2023-2024 formula had gluten and wants to know if the facility they were made in is gluten-free. Caller mentioned that she had a celiac disease and Paxlovid should be gluten free. She had taken 4 of the 5 Pfizer Covid Vaccines but each time she took it she got a very fast heartbeat and lasts for quite a while, sometime months. Stated the very fast heartbeat started immediately after the vaccine, either same day or following day. Did not recall specifics. She would be sitting and just thinking about what she had to do and her heart would just race. Known it was as long as a couple of months at times. It was more than she could handle. She was worried about taking another Covid vaccine because of that reaction and so she wanted to know if the Pfizer vaccine had gluten. Expiry Date of Pfizer 19 Covid vaccines: Unknown, Caller stated she took the 1st and 2nd, she did not know year, it was when they came out. Took the 3rd and did not think she did the 4th apparently it was not working for whatever reason and her doctor did not recommend the 4th and then she took the 5th. Guesses about a year ago. It was whenever we came out with the 5th she called and made appointment. Patient height had lost a couple inches with age. Concomitant Medications: no, the only medications she took was baby aspirin a day. started taking probably 8-10 years ago and was still taking. Crestor was taking 20mg recently now but was taking 10mg at the time she believed. Started taking many years ago, she had a history of strokes and high cholesterol and psoriatic arthritis. Psoriatic arthritis was diagnosed a couple years after psoriasis diagnoses so around 35 or so. Still taking. Prior Vaccinations (within 4 weeks): no, did not get the flu vaccine but it was way before that thinks she waited 2 months or so. Not every time because when she took the 2nd and 3rd and 5th it was not around flu season if she was not mistaken. It was only that vaccine. No Family Medical History Relevant to Adverse Events.
