getting lightheaded and dizzy all the time; Seizure; This is a spontaneous report from a contactable consumer (patient) and a consumer (patient's ex-wife/ roommate) A 47-year-old male patient received the first dose of BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE, lot number: ER2613 and expiration date not provided), via an unspecified route of administration, on 01May2021 (at the age of 47-year-old), at single dose, for COVID-19 immunization. Medical history included blood cholesterol, high blood pressure, ongoing seizures from 1991; patient was being hit in the head with a steel baseball bat 13 times, and had a lot of brain damage; and ongoing sleep. Prior Vaccinations (within 4 weeks) provided as no. Concomitant medications included ongoing topiramate (TROKENDI XR) for seizure, ongoing allopurinol (ELAVIL) for sleep, and medication for cholesterol and one for high blood pressure. Patient had been on topiramate a couple of months. They were working with him to get him better than he was because he was having a lot of the little ones. He got the pill packs. He tried the little compartment things and they weren't working. Roommate suggested they try the pill packs to make it easier. There was the time on the packs. The patient experienced seizures on 13May2021; getting lightheaded and dizzy all the time on unknown date. Patient's second dose was scheduled 22May2021. Due to symptoms that he experienced he was afraid to take second dose. Patient had petite mal seizure last night on 13May2021, he got ahold of the doctor and got an appointment with his family doctor. They don't know about the seizure yet. Patient was feeling ok until he got the shot. Now, he was back to getting lightheaded and dizzy all the time. Patient got social security and had a hard time remembering his phone number. Patient's ex-wife clarified that patient called the doctor and got an appointment. He had upcoming appointment. The doctor wanted him to go to the emergency room. She had known him since 2005. When he had a mild seizure the ER doesn't do anything for him. They just leave him in the bed and wait until he comes to his senses. She just told patient to go in his room and lay down and offered him paracetamol (TYLENOL) and all that stuff. She couldn't move him when he was having one of the worse seizures because he turns into a board. She tried to get him aware. They didn't last long. Patient had grand-mal seizures since the age of 18 after being hit in the head with a steel baseball bat 13 times. He had a lot of brain damage. The brain can't fix itself. She was the only one that knows how to handle him. Patient's ex-wife listed at the doctor office because patient had a hard time explaining things and stutters a lot, he can't answer right away. The seizure patient had yesterday was a petite mal seizure. It wasn't a full blown grand mal seizure. He had three different phases of seizures. He had the staring one where he was looking out in space. Then he had the next one that happened in the car. He sat down and put his head back to relax. She thought he was taking a break, but it was a seizure. She touches him to focus and get him back. At night was when he has the worst ones where he looses control of his bladder, foams at the mouth, and turns into a board. He can't bend. He has only had 3 of those in the time she had known him. The other ones he had quite often. The quicker he comes out of it the less headache he has after it. If they let it run its course he has a bad headache and nausea. She tries to open his eyes because he comes out better. One time when he had grand mal seizure she couldn't get him rolled over and had to get help. Even though it was saliva and he was foaming at the mouth she was afraid he would choke on it. He had one starring seizure shortly before the COVID vaccine. He had them a lot. If they take blood or run scan it won't show patient had a seizure. For a little while patient and his roommate weren't together. If he did have seizure during that time he got himself out of it. He has only had 3 bad ones since 2005. Patient told his doctor that he thought it was related to the COVID shot. Patient's ex-wife didn't believe that was what caused the seizure (She thought if it was related it would have happened within 20 minutes of getting the vaccine). She thought he just had one. It played in his mind that he had the shot. Patient's brain stopped growing when he was 18 due to damage. The outcome of the events was unknown.; Sender's Comments: Based on known drug safety profile, there is reasonable possibility of causal association between the events Seizures, Dizziness and the suspect BNT162B2.
