- Patients with the medical history of allergy to ropinirole HCl in the past.
- Patients with the medical history of Augmentation to ropinirole HCl or other dopamine agonists in the past and those who have experienced early morning RLS symptoms. Augmentation is defined as below: RLS appear 2 hours earlier than the pre-treatment. Symptoms become severer than the pre-treatment. Symptoms which start after less time at rest than they did before treatment. The RLS extend to other sites (e.g. arm and trunk).
