Two Cases of Deep Vein Thrombosis Associated with a Combined Paroxetine and Zotepine Therapy

Abstract

Thromboembolic events arising as a side-effect of neuroleptic and thymoleptic therapy, although rare, represent serious complications. We report on two patients suffering from an acute deep vein thrombosis after administration of a combined therapy with paroxetine and zotepine. The absence of common risk factors for the development of venous thrombosis in both patients led us to reconsider the potential impact that the drugs administered may have on thrombogenesis. Possible influences of the neuroleptic and thymoleptic therapy on the coagulation system are discussed. Although the clinical observations do not necessarily imply a strict causal relationship between drug administration and thrombosis, there are features of these two cases that should enhance our awareness of the possibility of thrombotic events occurring as a consequence of neuroleptic and thymoleptic therapy.
