Dexmethylphenidate and Tranylcypromine should not be taken together without medical supervision.
Why these two interactSources for why these two interact: Jumps to this entry in the sources and references list at the end of the page.
MAOI blocks catecholamine breakdown; combining with sympathomimetics can trigger hypertensive crisis.
Inferred from a shared mechanism, not documented for this specific pair. The same explanation is applied to other combinations that work the same way.

Separating the doses does not solve this one. The concern is the combined effect in the body, not absorption timing, so spacing them out is not a workaround.
