The patient underwent the following laboratory tests and procedures: Blood pressure measurement: (26Dec2025) 138 (systolic, notes: or SBP, "top number"); (29Dec2025) her SBP was 220. Therapeutic measures were taken as a result of hypertension. Additional information: The consumer stated that she received a COVID-19 shot on December 26, the day after Christmas. At the time of vaccination, her blood pressure was reported as normal prior to receiving the shot, with the upper number noted as 38. On the following Monday, December 29, she visited another doctor's office, where her blood pressure was measured and found to be 220. She reported that her systolic blood pressure stayed elevated "all night and morning." The next morning, she contacted her primary care physician, who was described as "really concerned." The consumer stated that she has no history of hypertension or use of blood pressure medications but noted a prior history of "white coat" hypertension, with systolic blood pressure never exceeding 150-160. The healthcare provider advised against frequent blood pressure monitoring, as additional stress could contribute to elevated readings. On Tuesday morning, her systolic blood pressure was reported as 190. She brought her blood pressure machine to her healthcare provider to check its calibration. That night, she took her first blood pressure medication, although the specific medication could not be confirmed. She stated that she experienced a "metallic taste" in her mouth both prior to taking the blood pressure medication and after receiving the COVID-19 vaccine. She was informed that patient-specific factors may affect how individuals respond to medications and that her healthcare provider was in the best position to guide her care. She was referred back to her healthcare provider for further guidance. The consumer reported experiencing a metallic taste between receiving the Pfizer COVID-19 vaccine and taking the blood pressure medication.The consumer reported that the vaccine administered was the Pfizer COVID-19 vaccine for seniors, also referred to as Pfizer COVID-19 Plus (clarified as Pfizer COVID-19 Vaccine). She stated that she had never previously received the Pfizer COVID-19 vaccine and questioned whether the vaccination could have triggered elevated blood pressure, as she did not want to be treated for hypertension if she did not have a prior history. When the concern was paraphrased, the consumer stated that on the 26th in the afternoon she received the COVID-19 shot and that her blood pressure at that time was 38, which she considered normal for her age group. She further stated that on Monday morning, during a visit to another doctor's office, her blood pressure was recorded as 220, which she had never experienced before. She explained that during prior doctor visits her blood pressure might occasionally be around 58 due to situational factors, but it had never been as high as 220. The consumer wanted to know whether this could be a side effect of the COVID-19 vaccine and, if so, how long it might last. She mentioned that she had read online that the vaccine could cause high blood pressure but was unsure of the accuracy of that information. When clarified whether she received the Pfizer COVID-19 vaccine or a Moderna shot, the consumer stated that, according to her medical records and her doctor's report, she received the Pfizer COVID-19 vaccine, When clarified whether she took the Pfizer COVID-19 vaccine and experienced a blood pressure problem, the consumer stated yes and the consumer stated that she had many questions because she had to return to her doctor, as her blood pressure remained elevated and the doctor was concerned and initiated blood pressure medication, which she had never taken before. She expressed concern about potential side effects, specifically whether the vaccine could increase blood pressure. No follow-up attempts are possible.
