Requip (Ropinirole HCL) is used alone or with other medications to treat Parkinson's disease. It can improve your ability to move and decrease shakiness (tremor), stiffness, slowed movement, and unsteadiness. It may also decrease the number of episodes of not being able to move ("on-off syndrome").
Ropinirole is also used to treat restless legs syndrome (RLS). It may improve your sleep by decreasing the urge to move your legs and decreasing uncomfortable/unpleasant feelings in the legs. This medication works by helping to restore the balance of a certain natural substance (dopamine) in the brain.
