A 78-year-old female patient received BNT162B2 via an unspecified route of administration on 08Oct2021 about 10:30-11am (at 78-year-old) (Lot Number: 3011358A; Expiration Date: 30Nov2021) as dose 3 (booster), single in arm right for COVID-19 immunisation. Other suspect drugs included ongoing diltazem (Product dispensed in pharmacy vial) at 180mg, 1 capsule by mouth once daily in the evening for cardiac issues/problems; ongoing losartan (does not have with her at time of report, in pharmacy bottle) for heart issues/problems; unspecified other heart medicines (Product dispensed in pharmacy vial) and unspecified heart monitor for heart issues/problems; ongoing rivaroxaban (XARELTO, Product dispensed in pharmacy vial) at 20mg, 1 tablet by mouth in the evening as blood thinner. Medical history included heart problems, atrial fibrillation (afib). Concomitant vaccine (within 4 weeks) included flu shot back in Sep2021 the one she gets every year. The patient previously received BNT162B2 on 17Feb2021 (Lot Number: EN6201; Expiration Date: 31Jun2021 (as reported)) as first single dose, and on 10Mar2021 (Lot Number: EN6201; Expiration Date: 30Jun2021 (as reported)) as second single dose; all at age of 77-year-old. She got pneumonia shot about 2 years ago. Because she is 78, heart doctor told her to wait 21 days after flu shot, heart, afib, lots of things. The patient had a lot of pain and still had pain in the arm where she got the shot. Then, on "Saturday" (09Oct2021) she had such terrible shooting pains in her leg and was weak and was in church and fell over and they couldn't get her up. She did get up and they kept her in a chair. Had jumpers, stabbing shooting pains and they ended up bringing communion to her and didn't let her move, but she still got the stabbing pains in her leg, arm, and neck. Is not really certain because she does have heart problems. Then went home and that was kind of bad because she had things to do. She did record some on her heart monitor and had this pretty much all day the rest of "Saturday", all of "Sunday" (10Oct2021) and then on "Monday" (11Oct2021) morning to about 10am she didn't have pain anymore. She didn't know if it was because of her heart issues. Still has aches in arm where she got the shot and has never had this in all of her life. Has gotten shots over the years and has never had pain from a shot. When she got them she doesn't even blink, but this one was kind of amazing with the pain. She was feeling better, but the lady that helped her at church talked to her this morning and asked if she had reported this and she didn't know if she should or not because she does already have history of heart problems, but she didn't have this consistent issue. She has other heart issues because of that she took diltiazem and other heart medicines, but she felt better "today" (12Oct2021), but felt she did need to report this. Unable to provide the NDC, Lot or expiry for Diltiazem or other heart medicines from their local pharmacy bottle. She took losartan and rivaroxaban which are also in pharmacy bottles. She has to get a magnifying glass because the little vaccine card was so tiny. She had a running heart monitor that has been on since "Wednesday" for the past 2 weeks, but unable to provide any further details about the monitor. She also had loss weight. The action taken in response to the event for diltazem and losartan was dose not changed; for other suspect drugs except BNT162B2 was unknown. The outcome of events heart disorder, weight loss was unknown; of events leg pain, vaccination site pain, pain, neck pain was not resolved; of event weakness, falling down was resolving.
