Allergic reaction; He said the floor doesn't look steady to me which meant he was a little weak or dizzy; He said the floor doesn't look steady to me which meant he was a little weak or dizzy; Forehead was dripping and it was cold, so the cold sweat coming from the forehead; His feet bothered him after that shot, he couldn't really describe what it was, but he told me it went right down to his feet and that's probably why he didn't feel right; Excessive tired to the point that he didn't want to go to work; Saliva for a week and a half, it's just saliva in his mouth that kept on foaming up; Didn't feel well; He didn't feel like he was standing on solid ground. It was him that wasn't solid; Headache; This is a spontaneous case received from a contactable consumer reported behalf of her husband. A 73 years old patient received 1st dose of BNT162B2 (lot/Batch: EN6206) on 13Mar2021 at single dose on left arm for covid-19 immunization. Medical history was High blood pressure (Treatment of high blood pressure: "Lisinopril dose one a day and dose is 12.5 according to it, it says here is HCTZ 10-12.5 mg it's oral tablet takes one at breakfast time); And then something else he takes because we had a storm earlier in summer, he was working where he works and wind just blew him face down into concrete side wall, but he put his arm up to resist it off, so he has been back and forth with his neurologist on this." There is another one that he does take because of hitting the side walk when I told him the wind blew him the side walk, he put his arm up but he gets a little dizzy once in a while because of that. It's Meclizine 25 mg, tablet, afternoon and evening 2 times a day." Concomitant drugs included Lisinopril, HCTZ and Meclizine. This past three weeks ago, 'my husband and I' (not clear) had our first injection for the Pfizer and within 4 minutes he was showing all kinds of reaction to it and he know he does not have reactions to very much of anything. I have no idea like it was something within the Pfizer medication that he was allergic to, allergic reaction. He stood on the floor I didn't figure out why he was standing up, he said the floor doesn't look steady to me which meant he was a little weak or dizzy whatever I don't know, so I reached over and I looked at his forehead and I said his forehead was dripping and I touched his forehead and it was cold, so the cold sweat coming from the forehead." He was excessively tired for almost 2 weeks. Like I said he kept on standing up the couple of times and I said what's the matter and he said I don't feel like I am standing on a solid ground and I said yes you are, then he told me a few days later that his feet bothered him after that shot, he couldn't really describe what it was, but he told me it went right down to his feet and that's probably why he didn't feel right. So, anyway I end up calling over an RN and she and another RN had to take him over to take his blood pressure, his blood pressure went down and now only he had high blood pressure, he took his medication (Unspecified Medication) that morning like he always does and it went down to 107/70 and when they gave him a small bottle of water to drink and they said just stand up and take it. Took the medication stood up and it was 132/80, it was probably more than his normal. So, I mean I couldn't understand what was happening that he was tired through, excessive tired to the point that he didn't want to go to work, so I mean I didn't question what's wrong specially when I looked over and his forehead just dripping, for approximate 4 minutes after the injection. So, I mean I really don't know to have been that way. Then often had, he told me he had 'more' (not clear) saliva for a week and a half, it's just saliva in his mouth that kept on foaming up. I had noted to if this was anything that was never him, he has never had lot of saliva in his mouth anyway. But, this side of him of course it showed it was working and that lasted almost 2 weeks as well, 2 week I think 2 weeks. And now he is starting to feel better but he didn't feel well but better than 2 weeks after the first injection. I had taken that was on 13th, 13th took him to his doctor and he recommended to not take a second one. He felt very weak, I mean this took 2 weeks to go away. He did mention that when he stood up he didn't feel like he was standing on solid ground and I know this as I have been there probably for more than 50 years, so of course he was. He received them, his blood pressure dropped to a 107/70 went that down, changing back to 132/80, actually they gave him a bottle of water in between and he did drink water for it so. And his forehead was dripping cold sweat and he told me later that he felt something strange in feet and that's why he was standing up I couldn't figure that part out in fact he was on solid floor or solid ground, so I am thinking the weakness set in him very quickly. So, that he was really dizzy, I don't know and that's why I said I called over the RN and she grabbed another RN and they helped him over to take his blood pressure they took it down it was almost 107/70. Now if he has got high blood pressure, it just the blood pressure going to be really in morning and this is at 5:30 at night, doesn't mean like and he is a lot to me. And he had excess saliva in his mouth seem to be foaming in his mouth. I don't know if you had any of these reactions or unless it's just him I really don't know. When probed for the start date of the events (event not specified), reporter stated, "Approximate 5:39, maybe 5:39, 5:40 in the evening which was last month, that on the 13th." Reporter confirmed that patient would not go for second dose of vaccine and that reporter is due for second dose on this Saturday. And according to what I understand and what I was told 107/70 wasn't trending down, to me it was, but I am not a doctor nor a nurse or any other professional to have said not in medical field but when his forehead started dripping cold sweat and he was acting little strange and standing up and what is wrong because I was right next to him, I said what is wrong, he said I feel like I am falling down. The biggest one that bothers him beside being also retired for 2 weeks. He keeps on getting this foam in his mouth from saliva, excess saliva foam and that has no idea what's close to. High blood pressure, he had taken that tablet (Unspecified Medication) that morning. Actually the tiredness is gone away, the blood pressure is back to normal, like I said he was absolutely tired for 2 weeks and I think it coincide with Pfizer's 1 to 2 days. He is also having a headache and he just take Tylenol for that. Outcome of the event was unknown.  No follow up attempts needed. Information about lot/ batch number not requested.
