Anatomical Location of Administration of Pfizer vaccine considered as suspect was Arm Left, shoulder. Caller stated he was calling regarding the Pfizer Covid-19 shot. He wanted to call and make sure. He actually had Covid in Mar2020. He believed it was a near experience, near hospitalization experience. After taking the first dosage, he had symptoms like fever and chills. He just took the second dose last Thursday and was feeling a little more fever and chills, things he thought were natural. Asked if it was normal to feel these symptoms. Fever and chills: They occurred in almost the same time frame with both the first and second shots. It was within 12 hours. With the first shot, it lasted about 12-16 hours. With the second shot, it lasted a little longer, about 24 hours. Treatment: He took Tylenol for both occurrences. There were no medical conditions that he was aware of. Actually, before the second dose, he had gotten an EKG on his heart because he wanted to make sure he was healthy. When he got the shot, it felt like the first shot, like his body was getting all of these symptoms again, which was fine. It was unexpected a little with the second shot. He had joint pain, muscle pain and aches, fever, chills and headaches. It was the same thing with the second dose. It was the same time frame as the fever and the chills. He always got them about 12 hours after the shot was administered. This was why on the second dose he went earlier in the day, so he could get the symptoms earlier and into the night and until the morning. Then, he would be good to go the next day. At the same time, the doctor had actually prescribed before the shot, some anxiety medication. He was anxious with the first dose. He took the medicine today, for the first time. What was odd, was that the medication did not help that feeling. Caller stated that he was prescribed 2 of them and he has only taken one, the Propranolol. Propranolol 10mg was prescribed to take regularly as needed when he does not get sleep and has really bad anxiety. He was also prescribed Escitalopram 10mg, to take regular, one daily. He has not taken it yet. He really has been weighing this shot out. He was not feeling this was as bad as he is now. Before he got the shot, his anxiety was kind of under control and he was able to sleep perfectly fine. There was a Product Complaint. Description of complaint: While reporting side effects from the Pfizer Covid-19 vaccine, caller mentioned he was prescribed Propranolol for anxiety and he took one today and stated it hasn't helped. He was also prescribed Escitalopram 10mg, to take regular, one daily. He has not taken it yet. He really has been weighing this shot out. He was not feeling this was as bad as he was now.
