A Case of Drug-Induced Immune Thrombocytopenia Caused by Haloperidol.

Drug-induced immune thrombocytopenia (DITP) is a rare but potentially fatal condition caused by immune responses to certain drugs, leading to platelet destruction or impaired production. Commonly implicated drugs include quinine, sulfamethoxazole, penicillin, and linezolid. Haloperidol is an extremely rare causative agent, with only two previous cases reported. This case highlights a rapid onset of DITP following haloperidol administration. Clinicians should remain aware that haloperidol may be a potential cause of drug-induced thrombocytopenia, including rare thrombotic thrombocytopenia. Prompt recognition and timely intervention are critical for ensuring positive clinical outcomes in affected patients.
