Abstract
Platelets are one of the important cells in the human blood that regulate the coagulation system. Abnormalities in platelets may lead to thrombosis or bleeding. Acute thrombocytopaenia carries a wide differential in a hospitalised patient, and drug-induced thrombocytopaenia is one of the uncommon findings. This case report describes teicoplanin-induced thrombocytopaenia in a patient who was being treated with this antibiotic and then developed thrombocytopaenia to a critically low level. This low level of platelets predisposes to bleeding, either minor or major. However, prompt recognition and stopping the offending drug reverse the process of ongoing thrombocytopaenia.
