Requip (ropinirole) has some of the same effects as a chemical called dopamine, which occurs naturally in your body. Low levels of dopamine in the brain are associated with Parkinson’s disease.
Requip is used to treat symptoms of Parkinson’s disease (stiffness, tremors, muscle spasms, and poor muscle control). This medicine is also used to treat restless legs syndrome (RLS). Only immediate-release Requip is approved to treat both Parkinson symptoms and RLS. Extended-release Requip XL is only approved to treat Parkinson symptoms.
