Key Clinical Message:
- Pericardial effusion leading to cardiac tamponade can occur due to a
multitude of etiologies, one of which is medication adverse effects
- In ET patients on anagrelide with pericardial effusion, a drug-induced
etiology should be considered as an adverse reaction
- In our case the decision to continue or to stop anagrelide while
managing the pericardial effusion should be tailored to each patient
individually through shared decision making.
