Before initiating treatment with INBRIJA, advise patients about the potential to develop drowsiness and ask about factors that may increase the risk for somnolence with INBRIJA such as the concomitant use of sedating medications and the presence of sleep disorders

ROPINIROLE

5 WARNINGS AND PRECAUTIONS Sudden onset of sleep and somnolence may occur ( 5
Although many of these patients reported somnolence while on ropinirole, some perceived that they had no warning signs, such as excessive drowsiness, and believed that they were alert immediately prior to the event
Before initiating treatment with ropinirole, patients should be advised of the potential to develop drowsiness and specifically asked about factors that may increase the risk with ropinirole such as concomitant sedating medications or alcohol, the presence of sleep disorders (other than RLS), and concomitant medications that increase ropinirole plasma levels (e
Patients on ropinirole should be monitored for signs and symptoms of orthostatic hypotension, especially during dose escalation, and should be informed of the risk for syncope and hypotension [ see Patient Counseling Information ( 17 )]
