Griffonia Simplicifolia and Maprotiline

Here is the interaction we found between these two, with the evidence behind it.

Moderate

ANTIDEPRESSANT DRUGS

Why this applies to Maprotiline

Maprotiline falls under ANTIDEPRESSANT DRUGS — the group Griffonia Simplicifolia interacts with.

Theoretically, taking Griffonia simplicifolia seed extract with antidepressant drugs might increase the risk of serotonergic adverse effects, such as serotonin syndrome and cerebral vasoconstrictive disorders such as Call-Fleming syndrome.
Griffonia simplicifolia seed extract contains 5-HTP. Taking 5-HTP with antidepressant drugs increases the risk of serotonergic adverse effects.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the thing to keep in mind with Griffonia and Maprotiline (Ludiomil). Griffonia seeds are a natural source of 5-HTP, which your body turns into serotonin. Maprotiline already raises serotonin and similar messengers in your brain, so stacking the two could push serotonin too high. That's what we mean by a serotonergic effect.

If serotonin climbs too far, you can get what we call serotonin syndrome: agitation, a racing heart, sweating, shivering, muscle twitching, or confusion. This concern is theoretical and based on how these two work, not on strong human studies, so I don't want to alarm you. Still, it's a real enough possibility that I'd ask you to check with your pharmacist or doctor before combining them, rather than starting Griffonia on your own.

From our pharmacist’s overview on the Maprotiline page

“The riskiest pairing on this page belongs to lithium. Taken alongside a serotonergic antidepressant like maprotiline (Ludiomil), it can both mask and raise the odds of serotonin syndrome, a dangerous buildup of serotonin activity, and it earns one of the list's two major ratings for that reason.”

Griffonia simplicifolia is a West African shrub whose seeds are a natural source of 5-HTP, a building block of the brain chemical serotonin.
