A 73-year-old female patient received first dose of bnt162b2 (PFIZER-BIONTECH COVID-19 VACCINE, Solution for Injection, Batch/Lot Number: EN6202), via an unspecified route of administration, administered in deltoid left on 26Feb2021 at 18:45 (6:45 PM) (at the age of 73-year-old) as dose 1, single for COVID-19 immunization. Medical history included allergy to sulfa drugs, anxiety, cholesterol, blood pressure, ADHD, throat looks red.

The patient previously took flu shot (Patient had a flu shot in September or October), first shingles shot; macrodantin and experienced allergy. On an unspecified date in 2021, the patient experienced uvula was itching like crazy. The patient stated received the first dose of the vaccine on Friday. She has a history of an allergy to sulfa drugs and Macrodantin and that was a slow anaphylactic reaction and it did not happen immediately. Yesterday she had raspberry sherbet and her uvula was itchy. She had some more sherbet in the evening and had more itching. She went to bed and in the middle of night she sucked on two honey lemon lozenges and it made the roof of her mouth a little bumpy. This morning her throat is red and she has had to take Benadryl. She is prone to anxiety attacks and took 7.5 mg Tranxene and gargled with salt water. She stated she may be anxious. She is thinking she needs to take another Tranxene and Benadryl and gargle with salt water and just relax. She asked could this be an allergic reaction 3 to 4 days later. What should she look for with an allergic reaction before she would call doctor. She asked if I recommended, she take these medications prior to calling her doctor. Patient got the Pfizer vaccine on Friday at 6:45PM. She has read what to expect and she downloaded Pfizer's sheet. She had to stay after because she is allergic to Sulfa and Macrodantin. Yesterday she ate something she hasn't had in 3 or 4 years, raspberry sherbet. She has undiagnosed food allergies. Her uvula was itching like crazy. She has had that before but didn't know what caused it. Later she had double the raspberry sherbet and started itching again. She had no difficulty breathing. She took a 50mg Benadryl when she woke up this morning. She is prone to anxiety attacks. She took 7.5mg of Tranxene. She hasn't eaten. She gargled with salt water and had coffee, but she hasn't eaten anything. Could this be an allergy thing from sherbet or can she have a reaction three or four days after receiving the vaccine. Patient ate the raspberry sherbet and her uvula started itching about 3:00PM. When she ate the sherbet again she had more like a whole cup and that was between 7:30PM and 8:00PM. She had itching. She went to bed and fell asleep. There wasn't anything else but itching. Her house is dry. In the morning she had mucus in the back of her throat. That is why she gargled. Her throat looks red. Patient is very self-aware. Her family had medical problems. When she gets upset her chest gets tight. That is why she took the Tranxene. She took Benadryl this morning around three or four, she only took one and it was 50mg. She took the Tranxene at 6:00 AM. Patient does not have NDC, lot, and expiry for Sulfa Drug and Macrodantin she was allergic to. She is 73 years old, and this happened when she was 5 years old, and 20 years old, and 34 years old. She hasn't had any since then. She had hives and a slow anaphylactic reaction. Tranxene and Benadryl lot numbers was not provided. Patient doesn't feel unhealthy, but when you have had anaphylactic shock and get an itchy throat you want to rule out since the sulfa and Macrodantin reaction was slow.
