Thrombocytopaenia Associated with Loxoprofen Sodium

Loxoprofen sodium is a phenyl propionic acid non-steroidal anti-inflammatory drug with a very good safety record. An unusual case of thrombocytopaenia most likely induced by loxoprofen sodium is reported. An 82-year-old woman developed thrombocytopaenia after taking loxoprofen sodium (180 mg/day) during treatment for trigeminal neuralgia and hip bone contusion. The patient's platelet count fell to 24,000/mm3, but her condition improved after discontinuing loxoprofen sodium.
