Black Pepper and Aripiprazole

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

Why Are There 2 Interactions?

Black Pepper interacts with whole categories of medication. Aripiprazole falls into 2 of those categories, so it can interact with Black Pepper 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 Aripiprazole

Aripiprazole falls under CYTOCHROME P450 2D6 (CYP2D6) SUBSTRATES — the group Black Pepper interacts with.

Theoretically, black pepper might increase levels of drugs metabolized by CYP2D6.
In vitro research suggests that some constituents of black pepper inhibit CYP2D6. This 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 aripiprazole (Abilify) and black pepper. Your body uses an enzyme called CYP2D6 to help clear aripiprazole. Lab studies hint that piperine, the active compound in black pepper, might slow that enzyme down a bit. If that happened in real life, more aripiprazole could linger in your system, which can mean stronger effects or more side effects like drowsiness, restlessness, dizziness, or feeling shaky.

The good news: this is theoretical, based only on test-tube research and not seen in actual people. Normal cooking amounts of pepper on your food almost certainly won't matter. Concentrated piperine supplements (often paired with turmeric) are where I'd pause. If you're using one of those, just run it by your pharmacist or doctor first.

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

2 of 2

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

Theoretically, black pepper might increase levels of drugs metabolized by CYP3A4.
In vitro research and pharmacokinetic simulation data suggest that piperine, a constituent of black pepper, as well as the pepper fruit seem to inhibit CYP3A4. This 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 explains PharmD, Clinical Pharmacist

Here's the gist with aripiprazole (Abilify): your liver uses an enzyme called CYP3A4 to help clear it out. Piperine, the active part of black pepper, may slow that enzyme down in lab studies. In theory, that could let more aripiprazole linger in your body, which might nudge up side effects like sleepiness, dizziness, restlessness, or feeling unusually drowsy.

I want to be honest about the strength here: this comes from test-tube and computer-modeling work, not real people, so it's pretty theoretical. The pinch of pepper on your dinner is very unlikely to matter. Concentrated piperine supplements (often paired with turmeric) are where I'd pause. Before adding one, just run it by your pharmacist or doctor so they can keep an eye on how you're feeling.

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.

About Black Pepper

What is Black Pepper?

Black Pepper
  • Flavoring and culinary use
  • Digestive complaints like bloating and indigestion
  • Boosting absorption of other supplements
  • Antioxidant and anti-inflammatory support
  • Cold and congestion remedies

Black pepper is a common kitchen spice that is generally safe in the amounts used in food. Its extract, piperine, is mostly added to supplements to help the body absorb other ingredients (like curcumin from turmeric). Strong human evidence for black pepper treating specific health conditions is limited, so use supplement-strength products with care and check with your pharmacist.
