This is a spontaneous report from a contactable consumer reporting for himself. An 81-year-old male consumer received first dose of bnt162b2 (PFIZER-BIONTECH COVID-19 VACCINE, Solution for injection, Lot number: EN6201, Expiry date: unknown) via an unspecified route of administration and administered on an unspecified anatomical location on 15Feb2021 (at the age of 81 years) as a single dose for COVID-19 immunization. Medical history included problem with his heart for 40 years it would beat rapidly. Concomitant medication included Sotalol  HCl taken to keep his heart from beating fast, amlodipine for blood pressure and finasteride for an unknown indication all from an unknown date and unknown if ongoing. The patient reported he was calling Pfizer and wanted to tell someone he got on 15Feb, the Pfizer COVID 19 shot and the next day he had a little itching, there was no rash he shouldn't tell where it was, it would start on the left front of his body and go to the right side in spots. he has been trying to get through, there was 39 ahead of him and he just gave up but today he got lucky. He called his doctor, and the practitioner told him to use Benadryl and he put it in one spot but it was not like a straight line but he put it in one spot and it took it right away but it came back a day later and now it was not working. There are no signs he thinks it was internal there was not a rash. He was concerned he wanted to tell this he was thinking maybe he should take some Aspirin or like some kind of pill because he thinks it was internal, he was concerned because the 08Mar was to get the second shot, he didn't have symptoms other than 3 days ago he got real cold and had chills and he said it was warm outside, he turned his heater on and the chills only lasted 2-3 minutes. He says he was okay everything was okay, he does not know if he will get a double reaction of that or if he should take something to keep it from getting real bad. He wants to get the other shot, he does not care about what happens but he wants to be prepared in case it doubles. He wants the shot, he wants to be with everybody, these people that don't want to get the shot, he thinks it was ridiculous. He got tested for the virus last May and he was negative but he told the people in his state they said they don't have symptoms but from what he understands someone might not have symptoms but still have the virus, it took 4 days but it was negative and he was happy about that. He got the first shot and it went well he had no problems, they were well organized at the medical center, they gave him an appointment and he doesn't have to wait he can come at any hour of the day with that card. He confirmed the first dose was given the 15Feb and the next will be the 8th of next month. The itching started the second or day something like that and it was in only one spot and he put the gel on and that took it away. it took him 5 days to get the gel because his car was broken down. He put the gel on it and it disappeared but the next day it came back in a different spot. It happens if his t-shirt touches it, like right now he doesn't feel it but if his t-shirt touches it he cannot take, he has to take it off and if he has no t-shirt on and he puts his hand over it, it stops itching. It was like he can electrify it or something. He was okay with it if he could take something that will help him get some sleep, it gave him trouble sleeping but if he could find something to take maybe it would not double on him if he can take something, like something internal to take. He does not know if this Benadryl comes in a pill or something. He was not too concerned about it, he knows people might get reactions.  He says he really thought about that. He took his mediation and this one was really strong it was Sotalol 80 mg HCl. His heart specialist gave him that and he took that at night. He says the Sotalol was to keep his heart from beating fast. He had a problem with his heart for 40 years it would  beat rapidly and no heart specialist could find out what was wrong until he moved from another city and his son works for a hospital in surgery and they recommended him to see a heart specialist and he drew a picture and said his heart was the shape of pear and blood circulates all around and he has this vein that was not normal that he was born with and it interferes and doesn't let the blood go up and the heart starts pumping and he said well lets take it off and he took it off and he has not had problems with that in a long time, its just gone. That doctor have him 40 more years back on his life. He reported when the Sotalol touches was tongue it was like acid like he thinks that could be why he reacted like that he takes it once in the morning. The Sotalol was in a blue, it was white on the bottle but there was a blue sticker that says Teva it was 100 tablets. NDC #. The lot, he needs a magnifying glass it was so small, the medicine says refill 16Feb2021. Expiration 20Jun2022 and lot 100018147. He also reported the Benadryl gel was not working and he will call heart specialist about this Sotalol he thinks it could be making him itch with the vaccine. He will have to make sure it was okay if he stops it for a couple days to see if it was gone or if he can stop using it until a waiting period and when it was gone he can start on that again. If they say its okay, he will call his doctor and Nurse Practitioner that was the one who answers the phone was the NP. They told him to take the Benadryl but they didn't tell him what kind so he did the gel he did not know if there was a pill form so he was going to check into that. Treatment include for the reported adverse events with benadryl. The patient underwent lab tests and procedures which included covid- 19: negative on an unknown date in May2020. The outcome of itching and it would start on the left front of his body and go to the right side in spots was not resolved/not recovered and for he got real cold and chills was resolved/ recovered on 22Feb2021. No follow up attempts are possible. No further information is expected.
