Kurin M, et al. - This systematic review is performed to determine whether the non-ergoline dopamine agonist ropinirole is correlated with nausea and vomiting in adults with restless legs syndrome (RLS). In individuals who used ropinirole for RLS, nausea and vomiting are quite common side effects. The prevalence of ropinirole-induced nausea and vomiting can grow substantially, as RLS is more widely recognized and treated. Findings reveal that ropinirole use should be considered as a cause of chronic nausea and vomiting.
