Symptoms reported following overdose of Azilect in doses ranging from 3-100 mg included dysphoria, hypomania, hypertensive crisis and serotonin syndrome.
Overdose can be associated with significant inhibition of both MAO-A and MAO-B. In a single-dose study, healthy volunteers received 20 mg/day and in a 10-day study, healthy volunteers received 10 mg/day. Adverse events were mild or moderate and not related to rasagiline treatment. In a dose escalation study in patients on chronic levodopa therapy treated with rasagiline 10 mg/day, there were reports of cardiovascular undesirable reactions (including hypertension and postural hypotension) which resolved following treatment discontinuation. These symptoms may resemble those observed with nonselective MAO inhibitors.
There is no specific antidote. In case of overdose, patients should be monitored and the appropriate symptomatic and supportive therapy instituted.
