Pressure ulcer induced by discontinuation of levodopa: Case report of an older patient with Parkinson's disease.

We report the case of a pressure ulcer that developed consequent to the discontinuation of levodopa (L-3,4-dihydroxyphenylalanine) administration. The 86-year-old female patient had a 5-year history of Parkinson's disease treated with levodopa. She developed a sacral pressure ulcer due to unanticipated immobilization induced by the discontinuation of levodopa. Discontinuation of mandatory drugs is therefore a risk factor for the development of pressure ulcers in patients with Parkinson's disease.
