We report a severe case of drug-induced parkinsonism (DIP) after allog
eneic BMT successfully treated with levodopa. BMT patients typically r
eceive numerous medications which can cause DIP, and mild cases of DIP
may remain unrecognized or be misdiagnosed. Physicians should be awar
e of DIP as a potential neurological complication after BMT to avoid f
urther administration of drugs that could aggravate symptoms.
