Dopamine Agonist-Associated Hiccup in Parkinson’s Disease: A Case Report

Hiccup is described as the sudden involuntary contraction of the diaphragm, and the intercostal muscles followed by the immediate closure of the glottis. Corticosteroids, benzodiazepines, and antibiotics may cause drug-induced hiccups. Dopamine agonist-induced hiccups were reported in patients diagnosed with Parkinson’s Disease (PD) in small number of cases. Here we report a patient diagnosed with PD who had severe hiccups with the use of two dopamine agonists in treatment, however hiccup was not reported with the use of Levodopa. This information may help to manage the treatment of PD, and avoid the unnecessary diagnostic procedures.
