Acute Thrombocytosis in a Patient Treated with Ertapenem.

Ertapenem, a carbapenem-type beta-lactam antibiotic, demonstrates broad-spectrum efficacy against a wide range of Gram-positive and Gram-negative bacteria, including aerobes and anaerobes. Importantly, it demonstrates resistance to virtually all beta-lactamases, including the extended spectrum beta-lactamases (ESBLs). Haematologic complications such as thrombocytosis, haemolysis, anaemia, and neutropenia are infrequent side effects associated with this drug. In this report, we present a rare case of ertapenem-induced thrombocytosis in a 62-year-old female patient who was admitted for a complicated urinary tract infection caused by Ertapenem was identified as the most likely cause of thrombocytosis.Discontinuing ertapenem normalised the platelet count.It is crucial for physicians to identify and address causes of thrombocytosis, particularly when related to medications, to avoid inadvertent complications and to ensure effective patient care.
