Maritime Pine and Inebilizumab-Cdon

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

Moderate

In vitro and animal research suggests that maritime pine bark extract has immunostimulant activity. This effect has not been reported in humans.
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 gist with Uplizna (inebilizumab). It's an infused medicine that calms down part of your immune system by lowering certain B cells, and it's used for conditions like neuromyelitis optica. Maritime pine bark, on the other hand, has shown immune-stimulating activity in lab dishes and animals. The concern is that, in theory, a supplement that nudges the immune system up could work against a drug whose whole job is to quiet it down, possibly making it a little less effective.

I want to be honest, though: this has only been seen in lab and animal studies, never in people, so it's more of a caution than a proven problem. Before adding Pycnogenol, just run it by your neurologist or pharmacist so they can keep an eye on things.
