Medical history included bad hearing problem. This consumer called on behalf of her husband to ask about possible side effects he was having. She reported that these possible side effects could be from Pfizer COVID-19 Vaccine or his other medications: glimepiride; Vitamin D; acetylsalicylic acid; apixaban; simvastatin; metoprolol; celecoxib; Vitamin C; famotidine; Vitamin B12; magnesium; and Immuneti. She was concerned about the possible side effects and wanted to ask Pfizer if these possible side effects could be from the Pfizer COVID-19 Vaccine or his other medications. Caller's husband was administered the Pfizer COVID-19 Vaccine on 15Jan2021. Caller also got her Pfizer COVID-19 Vaccine on 15Jan2021. Neither patient or caller had any problems with the product initially. Then her husband had onset of possible side effects last night. Starting 17Jan2021 after patient took his usual night medications, which caller was unable to clearly define which of the other suspect products that included, patient began to feel real bad. He said he smelled some kind of chemical and caller said she did not smell anything. Patient got to feeling worse and worse and they stayed up fairly late to see if he got to feeling better. When he got up this morning: 18Jan2021, he was feeling some better. He came in the room and when he put his medications in his mouth, before he even got them swallowed, he began to feel bad again-caller was unable to clearly define which of the other suspect products that included. Patient had been on simvastatin a long time and one time they took him off of this and started it back; he had been back on this for about 1 year. Metoprolol was discarded after 10th and 9th of 2021, documented as provided by reporter. Patient started it maybe 2-3 years ago. Vitamin C was Over the counter product, start date was probably 6-8 months ago. Vitamin B12 was probably started about 6-8 months ago. Magnesium was Over the counter product and probably started about 6-8 months ago. Caller verified that there are no other relevant products/medical conditions to provide for this report. She mentioned separately that patient had a bad hearing problem so caller handled his calls for him. The action taken in response to the events for all drugs (except for bnt162b2) was dose not changed. Outcome of events were unknown.  Information about Lot/Batch has been requested.
