Rasagiline Disease Interactions

Rasagiline should not be used in patients with moderate to severe hepatic impairment. Patients with mild hepatic impairment should not exceed a dose of 0.5 mg daily.

Dopamine agonists may impair the systemic regulation of blood pressure, with resultant orthostatic hypotension at any time, but especially during dose escalation. Additionally, patients with Parkinson's disease may have an impaired capacity to respond to an orthostatic challenge. For these reasons, patients with Parkinson's disease (or restless legs syndrome) who are being treated with dopaminergic agonists typically require careful monitoring for signs/symptoms of orthostatic hypotension, especially during dose escalation, and should be advised of this risk.

Ordinarily, patients with major psychotic disorder should not be treated with dopaminergic antiparkinsonian agents, because of the risk of exacerbating psychosis. Hallucinations and psychotic-like behavior have been reported with dopaminergic medications. In addition, certain medications used to treat psychosis may exacerbate the symptoms of Parkinson's disease and may decrease the effectiveness of these drugs. The use of bromocriptine in patients with severe psychotic disorders is not recommended.

Exacerbation of hypertension may occur during treatment with rasagiline. Dosage adjustment may be necessary if the elevation is sustained. Patients should be monitored for new onset hypertension or hypertension that is not well controlled after starting treatment.

Dose adjustment of rasagiline is not required for patients with mild or moderate renal impairment. However, rasagiline has not been studied in patients with severe renal impairment. Caution is advised if used.
