Tracking of Changes: 25-Feb-2022: Initial information was received. Follow up received on 14-Mar-2022 with the following updates:  Eliquis is under agreement with Agency.  Causality Assessment:  Drug: ELIQUIS,  Event: Pulmonary embolism, Dizziness, Balanced difficulty, Pleural effusion, Musculoskeletal pain, Fever, Prescribed underdose Per Reporter: No Information   Per Agency: Not Related    Causality Assessment:  Drug: BNT162B2 Event: Pulmonary embolism, Dizziness, Balanced difficulty, Pleural effusion, Musculoskeletal pain, Fever, Prescribed underdose Per Reporter: No Information   Per Agency: Related  Agency Comment: This patient developed multiple events after receiving apixaban. Based on limited information regarding definitive diagnosis and relevant medical history, the reported events off balance and dizziness are considered not related to apixaban. Past history of pulmonary embolism  and underlying thromboembolic risk are significant risk factors for another episode of pulmonary embolism, hence considered not related to apixaban.; Sender's Comments: Agency Comment: This patient developed multiple events after receiving apixaban.
