Back disorder; lower back issues; Feeling abnormal; felt fuzzy; Vaccination site pain; sore arm; Dizzy; Fatigue; Energy decreased; not feeling as much energy as before; Pain upon movement; walk about a block but then starts to hurt; This is a solicited report from a contactable consumer (patient) via a non-Pfizer sponsored program, based on the information received by Pfizer (Manufacturer Control No: 21K-163-3774842-00).   Solicited report from a consumer of a 60 year old female with events of heart/atrial flutter, atrial fibrillation, eye surgery and arm surgery and non-serious weight gain due to attempting to stop smoking, lower  back issues, felt fuzzy, got first dosage of covid-19 vaccine and experienced sore arm, fatigue and dizzy from  the blood thinners after surgery, still not feeling as much energy as before and walk about a block but then starts to hurt with humira 40mg/0.4ml (adalimumab). The patient had a relevant medical history of tobacco use/four cigarette sticks per day, seropositive high titer rheumatoid arthritis, fingers swelling, joint pain, joint swelling and lost of blood flow in hands and legs. On unknown dates, the patient experienced eye surgery, arm surgery, lower back issues, felt fuzzy, got first dosage of covid-19 vaccine and experienced sore arm, fatigue and dizzy from the blood thinners after surgery, still not feeling as much energy as before and walk about a block but then starts to hurt. In 2020, the patient experienced heart/atrial flutter and atrial fibrillation. In Sep2020, the patient experienced weight gain due to attempting to stop smoking. On 24Feb2021, the heart/atrial flutter and atrial fibrillation resolved. Covid-19 vaccine was also considered suspect. The patient had eye and arm surgery in the past. On 24Feb2021, she underwent pulmonary vein cryoballoon ablation surgery for the atrial fibrillation and atrial flutter. She had a procedure done and went into her heart and froze the nerve endings that were causing the atrial fibrillation, and also fixed the flutter in her heart. The causality as per reporter for this procedure was reported as no reasonable possibility. She still recovering. She discontinued the Humira two weeks before the surgery and took her last injection on 10Feb2021 and was paused it for four weeks, but she started back it on 10Mar2021. She follows up with her surgeon at the end of the month and she hopes this helps got her off of the blood thinners and other medicines, she been on for this. She stated that this was not related Humira. She was advised by her physician to increase the exercise to lose some weight. With her lower back issues, she was hoping that when she got off of the blood thinners, she could do pain shots again and start exercise. She could walk about a block but then she started to hurt. She had been careful with her diet also, cut out the salt also. This had nothing to do with Humira and she did not want to be contacted about this again for this also. She felt fuzzy, it took her most of the morning to get woken up. Her Doctor thinks once she would off of the blood thinners she would be back to normal. Other than that she feels fine. She does not wanted to be contacted about this. It was unknown if patient was enrolled in a COVID-19 Vaccine Trial. On unknown date, patient received first dose COVID-19 Vaccine manufactured by Pfizer, lot number unknown. She agreed to have physician contacted. Blood thinner was also considered as co-suspect.  Other medical history included abstains from alcohol, contrast dyes allergy manifested by scratch throat, allergy manifested by bowel movements (oral medications for rheumatoid arthritis; up to eight times a day and slept 15 hours per), prevent esophagus damage, heart, low thyroid, and attention-deficit/hyperactivity disorder. The patient's concomitant medications included pantoprazole to prevent esophagus damage, metoprolol for heart, levothyroxine for low thyroid, vortioxetine hydrobromide (TRINTELLIX) for depression, and dexamfetamine sulfate (DEXTROAMPHETAMINE) for attention-deficit/hyperactivity disorder. The patient underwent laboratory tests and procedures which included blood work: everything was fine in Jan2021; chemical stress test and treadmill stress test: confirmed atrial fibrillation and atrial flutter in Sep2020; body weight: gain in Sep2020; and X-ray: confirmed atrial fibrillation in Sep2020. The action taken in response to the events for adalimumab and apixaban was unknown. The patient recovered from atrial flutter and atrial fibrillation on 24Feb2021. Outcome of Feeling abnormal and Pain upon movement was unknown. The patient had not recovered from the remaining events.  Change History: On 05Mar2021, received updates to patient demographics, medical history, event information, reporter opinion of causality, suspect drug information, concomitant drug information, past drug information, laboratory/diagnostic procedures and narrative description. The events of "atrial flutter", "atrial fibrillation" and "weight gain due to attempting to stop smoking" were added. On 11Mar2021, received updates to patient demographics, medical history, event information, reporter opinion of causality, company opinion of causality, company alternative etiology, suspect drug information, laboratory/diagnostic procedures and narrative description. The events of "LOWER BACK ISSUES" and "WALK ABOUT A BLOCK BUT THEN STARTS TO HURT" were added. the event of "atrial flutter" was amended to "heart/atrial flutter".  On 08Apr2021, received updates to event information, reporter opinion of causality, company opinion of causality, company alternative etiology, suspect drug information and narrative description. The events of "felt fuzzy", "got first dosage of covid-19 vaccine and experienced sore arm", "fatigue and dizzy from the blood thinners after surgery" and "still not feeling as much energy as before" were added.   Causality for humira 40mg/0.4ml(adalimumab): The reporter's causality for the event(s) of heart/atrial flutter, atrial fibrillation, eye surgery, arm surgery, weight gain due to attempting to stop smoking, lower back issues, got first dosage of covid-19 vaccine and experienced sore arm, fatigue and dizzy from the blood THINNERS after surgery unknown onset and fatigue and dizzy from the blood thinners after surgery unknown onset with humira 40mg/0.4ml(adalimumab) was no reasonable possibility. The reporter's causality for the event(s) of felt fuzzy, still not feeling as much energy as before and walk about a block but then starts to hurt was not provided. Manufacturer opinion is that there is no reasonable possibility that the events of heart/atrial flutter, atrial fibrillation, eye surgery, arm surgery, weight gain due to attempting to stop smoking, lower back issues, felt fuzzy, got first dosage of covid-19 vaccine and experienced sore arm, fatigue and dizzy from the blood thinners after surgery unknown onset, fatigue and dizzy from the blood thinners after surgery unknown onset, still not feeling as much energy as before and walk about a block but then starts to hurt are related to humira 40mg/0.4ml(adalimumab).   The reporter's assessment of the causal relationship of the events with BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE) was not provided at the time of this report. Since no determination has been received, the case is managed based on the company causality assessment.  No follow-up attempts are possible; information about batch number cannot be obtained. No further information is expected.; Sender's Comments: Based on the current available information , the events of sore arm, fatigue and dizzy could be related to the suspected drug of BNT162B2. The other events are most likely related to an intercurrent or underlying condition which is not related to the suspected drug.  The impact of this report on the benefit/risk profile of the Pfizer product is evaluated as part of Pfizer procedures for safety evaluation, including the review and analysis of aggregate data for adverse events. Any safety concern identified as part of this review, as well as any appropriate action in response, will be promptly notified to Regulatory Authorities, Ethics Committees and Investigators, as appropriate.
