Boswellia Serrata and Risperidone

These two interact in 2 distinct ways. Each one is explained separately below.

Why Are There 2 Interactions?

Boswellia Serrata interacts with whole categories of medication. Risperidone falls into 2 of those categories, so it can interact with Boswellia Serrata in 2 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Moderate).

Moderate

CYTOCHROME P450 2D6 (CYP2D6) SUBSTRATES

1 of 2

Why this applies to Risperidone

Risperidone falls under CYTOCHROME P450 2D6 (CYP2D6) SUBSTRATES — the group Boswellia Serrata interacts with.

Theoretically, Boswellia serrata might increase the levels of CYP2D6 substrates.
In vitro research shows that Boswellia serrata gum resin inhibits CYP2D6 enzymes.
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 for risperidone: your body relies on a liver enzyme called CYP2D6 to help break it down. In test-tube studies, boswellia appears to slow that enzyme down a bit. If that effect carried over into real life, risperidone could clear a little more slowly and build up, which might mean stronger effects and more side effects like drowsiness, dizziness, low blood pressure when you stand, or restlessness and muscle stiffness.

I want to be honest, though: this is theoretical, based on lab data only, not real patient cases, so the actual risk is likely small. Risperidone isn't a prodrug, so more enzyme blocking means more drug, not less. Still, before adding boswellia, run it by your pharmacist or doctor so they can keep an eye on how you're feeling.

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

2 of 2

Risperidone also falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES.

Theoretically, Boswellia serrata might increase or decrease the levels and clinical effects of CYP3A4 substrates.
In vitro research shows that Boswellia serrata gum resin inhibits CYP3A4 enzymes. Other in vitro research shows that Boswellia serrata extract inhibits CYP3A4 enzymes at most concentrations, although it may modestly induce enzyme activity at low concentrations.
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

Your body clears risperidone partly through a liver enzyme called CYP3A4. In test tube studies, boswellic acids (the active part of Boswellia) seem to slow this enzyme down at most doses, though they may speed it up slightly at very low ones. If Boswellia blocks CYP3A4, risperidone could build up a bit more than usual, which might mean stronger side effects like drowsiness, dizziness, low blood pressure when standing, or stiffness and restlessness.

Here's the honest part: this is theoretical, based only on lab work, not on real people taking both together. So I wouldn't panic. Just don't start a Boswellia supplement without giving your pharmacist or doctor a heads-up, and let them know if you feel unusually sluggish or off.

What These Ratings Mean

Every interaction above is graded three ways — here’s the key to each label.

Severity how clinically significant the interaction is
Major

Clinically significant. Avoid the combination, or use only under close professional supervision.

Moderate

Usually worth avoiding or managing — may need monitoring, a dose change, or timing apart.

Minor

Generally not serious. Be aware of it and mention it to your pharmacist.

Likelihood how strong the evidence is that the interaction actually happens in people
  • LikelyWell-controlled human studies have demonstrated the likely existence of this interaction.
  • ProbableInteraction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports.
  • PossibleInteraction 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.
  • UnlikelyInteraction has been demonstrated in animal or in lab research but has been shown not to occur in humans.
Evidence the quality of the studies behind the rating (graded A–D)
  • AHigh-quality meta-analysis (quantitative systematic review).
  • BCase-control study.
  • CConsensus.
  • DAnecdotal evidence.

These ratings are for information only. Never start, stop, or otherwise change your therapy before speaking with your provider.
