Caller confirms no, she does not work as a healthcare professional, but states she takes care of her girl. She took another Tylenol again since the medication had already gone away. She clarifies she took another Tylenol and just a bit later, the swelling in her eyes started to go down. She confirms her eyes had been really swollen. Caller clarifies further that when she took the Tylenol, it helped her feel better. She confirms she is not still experiencing the swelling. She explains the day she took the pill before she went to get the Pfizer vaccine, when she came back, everything was okay. When the pill effects went away, and the injection started giving its reaction, she could see it. So, she took another Tylenol because she was afraid of the swelling at night when she was sleeping. Thankfully, nothing got swollen again. She took Tylenol every 3 hours, just to not get another reaction so her eyes wouldn't get swollen. On the second day, she didn't take anything and everything was okay. For example, she has taken Motrin. Before she could take any medicine and wouldn't get any allergy, but now, she gets a reaction and her eyes get swollen. Caller states she even had to go to Emergency room because her eyes got swollen and her throat got swollen as well. This is also when she took Benadryl. She clarifies this happened like a month ago. She was inside her house and went outside to the patio. Because the pollen was high that day, her eyes and nose started to be itchy and she started sneezing a lot. She was sneezing and sneezing. She went inside and she took Benadryl. Instead of the Benadryl lowering her symptoms, she started to get swollen and swollen. Her eyes were swollen and it felt like her lips were getting asleep/ numb. She ended up going to the Emergency Room because she felt like her whole face had gotten swollen. She states this was her first time taking Benadryl because she typically does not suffer from anything or get anything. She mentions she has taken Claritin but has never gotten any reaction with it, but Benadryl is what she had at hand. With the Benadryl, she never thought she was going to get swollen, but she did. Caller explains she doesn't have any NDC, Lot, or expiry date for the Benadryl. She states its the really small pills that the pharmacy sells, like the count is 4 or 5. The rest she threw away because she felt like it was best not to have them.
