Time lag between Linezolid and Thrombocytopenia


Thrombocytopenia could be multifactorial in ICU. One of the relative new cause is Linezolid (Zyvox). But thrombocytopenia with Zyvox usually doesn't occur upto 2 weeks with the initiation of treatment and could help in ruling out atleast one reason. Relatively overall its mild, reversible and due to myelosuppression. there is no evidence for anti-platelet or interference with platelet function.
