Summary
Methylphenidate increases catecholamine release and blocks reuptake, while safinamide inhibits MAO-B. Together they may produce marked blood pressure elevation and hypertensive crisis. Methylphenidate labeling contraindicates use with MAO inhibitors.
What this interaction means in plain words
Methylphenidate transdermal and Safinamide are not normally used together. Taking them at the same time is expected to cause harm or make one of them unsafe, so a different medicine is usually chosen for one of the two.
Why it happens
Reduced catecholamine metabolism from MAO inhibition adds to stimulant-induced catecholamine release, causing additive sympathomimetic effects.
What to do
Do not co-administer, and avoid methylphenidate for at least 14 days after stopping an MAO inhibitor. Monitor blood pressure if inadvertent exposure occurs.
