IMPORTANT SAFETY INFORMATION FOR XADAGO

WARNINGS AND PRECAUTIONS

XADAGO may cause or exacerbate hypertension. In clinical trials, the incidence of hypertension was 7%, 5%, and 4% for XADAGO 50mg, 100mg, and placebo respectively. Patients should be monitored after starting XADAGO for newonset hypertension or hypertension that is not adequately controlled. Dietary tyramine restriction is not required during treatment with recommended doses of XADAGO. However, patients should be advised to avoid foods containing a very high amount of tyramine because of the potential for severe increases in blood pressure, also referred to as hypertensive urgency, crisis, or emergency.
Patients treated with dopaminergic medications have reported falling asleep while engaged in activities of daily living. If a patient develops daytime sleepiness or episodes of falling asleep during activities that require full attention (e.g., driving a motor vehicle, conversations, eating), XADAGO should ordinarily be discontinued, or the patient should be advised to avoid driving and other potentially dangerous activities.
May cause dyskinesia (or exacerbate dyskinesia).
Patients with a major psychotic disorder should ordinarily not be treated with XADAGO because of the risk of exacerbating psychosis with an increase in central dopaminergic tone. Consider dosage reduction or discontinuation if hallucinations or psychotic-like behavior develop.
Patients can experience impulse control/compulsive behaviors while taking XADAGO. Because patients may not recognize these behaviors as abnormal, it is important for prescribers to specifically ask patients or their caregivers about new or increased abnormal behaviors.
Withdrawal-emergent hyperpyrexia and confusion, a symptom complex resembling neuroleptic malignant syndrome (characterized by elevated temperature, muscular rigidity, altered consciousness, and autonomic instability), with no other obvious etiology, has been reported in association with rapid dose reduction, withdrawal of, or changes in drugs that increase central dopaminergic tone.
Monitor periodically for visual changes in patients with a history of retinal/macular degeneration, uveitis, inherited retinal conditions, family history of hereditary retinal disease, albinism, retinitis pigmentosa, or any active retinopathy (e.g., diabetic retinopathy).

DOSING GUIDELINES & CONSIDERATIONS

The maximum recommended dosage of XADAGO in patients with moderate hepatic impairment is 50 mg once daily. Discontinue XADAGO if patient progresses from moderate to severe hepatic impairment. XADAGO is contraindicated in patients with severe hepatic impairment.

ADVERSE REACTIONS

In placebo-controlled studies, the most common adverse reactions associated with XADAGO treatment in which the incidence for XADAGO 100mg/day was at least 2% greater than the incidence for placebo were dyskinesia, fall, nausea, and insomnia.
