Musical hallucinations induced by drugs

Dipyridamole is an antiplatelet agent and a vasodilator which is increasingly being used for the secondary prevention of ischaemic stroke and transient ischemic attack, either alone or in combination with acetylsalicylic acid. We describe an 83-year-old woman who had developed musical hallucinations within days of initiating dipyridamole. Her psychiatric and neurological evaluation was otherwise, unremarkable. After the discontinuation of dipyridamole the hallucinations ceased within a couple of days. To the best of our knowledge this is the first case of auditory hallucinations associated with dipyridamole reported in the literature.
