Is Phenelzine safe with Synephrine?
No — not without a prescriber's sign-off. Phenelzine and Synephrine are flagged "Avoid" in DoseRoutine because MAOI blocks catecholamine breakdown; combining with sympathomimetics can trigger hypertensive crisis.
The short version
- Verdict
- Not together — this combination should be avoided.
- Timing
- 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.
- What to do
- Do not combine.
