The most significant difficulty in dopamine agonist (DA) treatment is its adverse effects which may outweigh its efficacy or even be disabling leading to discontinuation. Limited data is available to provide a head-to-head comparison of the discontinuation rates for DAs. We aimed to investigate the prevalence and characteristics of the discontinuation of pramipexole and ropinirole treatments and to determine the risk factors related to their discontinuation in patients with Parkinson’s disease (PD). The data of 329 patients that underwent DA treatment (pramipexole or ropinirole) were retrospectively determined. Demographics, disease duration, levodopa equivalent dose, dopamine agonist dosage, related adverse effects, duration of DA treatment, and the Hoehn and Yahr (HY) scale scores were compared between the two DA groups. The rate of discontinuation of the DAs due to adverse effects was 51.6%. Psychiatric side effects (14.3%) were the most common reason for discontinuation, and impulse control disorders (ICD) and pedal edema were the other prominent reasons. The discontinuation rate was higher among the patients with HY stage 2 and 3 in the pramipexole group, increased age at onset, and increased disease duration. In the ropinirole group, ICD had higher prevalence. The odds ratio of the ICD risk was found to be 2.58 times higher in the ropinirole group. Common side effects such as daytime sleepiness, constipation, and headache were not found to be reasons for the discontinuation of DAs; rather, the patients mostly discontinued these treatments due to psychosis, impulse control disorder, and pedal edema. It is noteworthy that adverse effects led to the discontinuation of treatment in over half of the patients. Further prospective randomized controlled studies on the reasons for DA discontinuation and related risk factors will be beneficial.
