cold sweats; Dizziness; blood pressure was higher than normal; was ashen; Diarrhea; Vomiting; arm pain; This is a spontaneous report from a contactable consumer (patient). A 66-year-old female patient received bnt162b2 (PFIZER BIONTECH COVID-19 MRNA VACCINE Solution for injection Lot Number: FL9264) via an unspecified route of administration in arm left on 11Feb2021 11:30 as dose 1, single for (age at vaccination: 66 years) COVID-19 immunisation. Medical history included ear virus, asthma, both from an unknown date and unknown if ongoing. Concomitant medications were not reported. History of all previous immunization with the Pfizer vaccine considered as suspect (or patient age at first and subsequent immunizations if dates of birth or immunizations are not available) as this is the patient's first dose. Additional vaccines administered on same date of the pfizer suspect was none. Prior Vaccinations (within 4 weeks) was none. On 12Feb2021, had arm pain. On 14Feb2021, had cold sweats, dizziness, blood pressure was higher than normal, was ashen, vomiting, diarrhea. The day after she had just normal arm pain and that's pretty much it. Then, she had something happen 2.5 days later, although she does not know if it was related to the vaccine or not, but she thought it was important enough to let the company know. She was a little nervous about taking the second vaccine. On 14Feb2021, Sunday she woke up at 2:30 a.m. had cold sweats. She was very dizzy. Her temperature was at 95 degrees and at one point, her temperature was below 95 degrees. She was ashen. Her blood pressure was higher than normal and usually her blood pressure was low. Her husband called the hospital, and she did a teleconference with a doctor. The doctor advised her to come into the hospital. She ended up starting to vomit and get diarrhea, so she did not ever get out of the house to go to the hospital. The next day, she started improving. She was almost normal now. She still had some dizziness. She does not know if it had anything to do with the vaccine or not. The adverse event did not result in emergency room or physician office. She stated that in her 20's, which was 40 years ago, she had an ear virus that caused dizziness like what she experienced now at the age 66. She does not know if the COVID-19 triggered the virus in her body to whatever, but the dizziness she experienced was very similar to the dizziness she experienced when she had the ear virus in her 20's. The caller explains the dizziness was tied to the position of her head. If she puts her head a certain way, she was still getting dizzy, so she does have a little dizziness when she lays her head down on a pillow. However, most of the dizziness was gone. The caller states it the same dizziness she experienced when she had the ear virus. At that point in time, the dizziness lasted 3 weeks and was severe. This dizziness had lasted for a couple of days. She does have asthma, but it was treated and was under control. She had no issues with it. She was prescribed Striverdi Respimat, 2 puffs daily, but she does not even take that. One puff daily control it, also prescribed Singulair. She forgets what the pill size was, but its one a day. She did not had these medications with her to provide any type of NDC, Lot number or expiry date from.
