A 49-year-old female patient received bnt162b2 (PFIZER-BIONTECH COVID-19 VACCINE), dose 2 at the age of 49-years-old via an unspecified route of administration on 11May2021 (Batch/Lot Number: EW0173) as DOSE 2, SINGLE for covid-19 immunisation; pantoprazole via an unspecified route of administration from Feb2021 to 12May2021 taken for reflux in her stomach.  Medical history included gastritis and hernia from an unknown date. The patient's concomitant medications were not reported. The patient received the first dose of bnt162b2 (PFIZER-BIONTECH COVID-19 VACCINE) at the age of 49-years-old on 20Apr2021 (lot: EW0164) for covid-19 immunisation. The patient reported that she received the second dose of Pfizer Covid19 vaccine on 11May2021. The day after on 12May2021, little dots appeared on her hands, as if they were bites. Those dots grew and so she called the hospital, but they gave her an appointment five days later. Doctor told her that was an allergic reaction but it was not associated with the vaccine. Doctor gave her treatment, but she did not specify what the treatment was. The dots kept on growing and now they appear on her arms, shoulders, chest, and back. She mentioned the hives are small, but after that they got swollen, grew, and turned red. After that, they dried and turned brown. They seem like skin burns. She has gone twice to the emergency room and had treatment but it has not been successful. She already reported the reaction online on VAERS. A nurse in the hospital also was going to report the situation. The nurse told her it was a reaction to the vaccine. She has been with these symptoms for the last few months. The spots have been increasing. The patient further clarified that first of all, it wasn't days after. It was the next day after getting the Pfizer COVID19 Vaccine. Those spots during the day grow. The same day they appear they start growing and swell. It is very extensive. Two to three days later they dry up and then appear in other areas of the body. It is on her chest, shoulders, arms, and also in her legs. That has been gradually. The transfer agent didn't mention her legs and they are horrible and it is on her face. She has taken pictures of everything. She has been two times to urgent care, two times to emergency room, has had five appointments with her primary care doctor, and one appointment with her dermatologist. Her back is full of that. It is entirely full. She has been having pain since an unspecified date in 2021. Her heart has been racing on an unspecified date in 2021. She has also had an EKG done, electrocardiogram. The first time she went to the doctor they gave her Benadryl and it didn't do anything, absolutely nothing. Then she went to urgent care and they administered some injection and nothing else. When she went to Urgent Care the second time they administered injections. The doctor was going to prescribe Benadryl, but she told them the Benadryl didn't help so he gave her Loratadine. When she went to ER, they prescribed her Pepcid. When she went to another ER they prescribed her with Triamcinolone, no pills just ointment. The ointment was Triamcinolone Acetonide Cream UTC 0.1%. This thing is her entire body. It is not only itching it is causing her pain. Her skin is sensitive. She has a 2 year old to take care of and she is not able to take care of him. Her entire body. The dermatologist  wanted to do a biopsy when it is swollen and red. When she went unfortunately it was drying up. It has increased. It is even more. It is very depressing. No one gives her a solution. She has been on here and not been taking care of myself. He needs her help. Emotionally this has been hard. She doesn't see a solution. She has called the dermatologist so he can see how it is in now, but they said they won't have a dermatologist appointment until October. She has to keep bearing with this pain and it burns through her whole body. In Jun2021, she had an endoscopy done. She had asked the doctor because she had the spots and they said it was separate and she could do her endoscopy. They said the spots were completely separate. She was taking Pantoprazole for reflux for her stomach. She stopped that when she started the spots. She had been taking the medication since February. In May when the spots appeared she stopped it thinking it may be that. She stopped all chemicals and all that thinking it was allergies. The patient underwent lab tests and procedures which included EKG: unknown on an unspecified date and endoscopy: unknown in Jun2021. Therapeutic measures were taken as a result of urticaria generalized, allergic reaction and skin discoloration which included hydrocortisone, Pepcid, Benadryl, Loratadine and triamcinolone acetonide cream. The action taken in response to the events for pantoprazole was permanently withdrawn on 12May2021. The patient did not recover from urticaria generalized and pain while the outcome of the other events was unknown.  Pfizer is a marketing authorization holder of pantoprazole in the country of incidence or the country where the product was purchased (if different). This may be a duplicate report if another marketing authorization holder of pantoprazole has submitted the same report to the regulatory authorities.  Follow-up attempts are completed. No further information is expected.
