Black Pepper and Ubrogepant

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. Ubrogepant 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 3A4 (CYP3A4) SUBSTRATES

1 of 2

Why this applies to Ubrogepant

Ubrogepant falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES — the group Black Pepper interacts with.

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

Here's the gist for Ubrelvy (ubrogepant): your body relies on a liver enzyme called CYP3A4 to break it down and clear it out. Piperine, the active part of black pepper, may slow that enzyme down a bit. In theory, that could let more ubrogepant linger in your system, which might mean stronger effects and a higher chance of side effects like nausea, sleepiness, or dry mouth.

I want to be honest about the evidence, though: this is based only on lab and computer-model studies, and it hasn't actually been seen in real people. The sprinkle of pepper on your dinner won't be an issue. Concentrated piperine supplements (often paired with turmeric) are the ones worth mentioning to your pharmacist before you combine them.

P-GLYCOPROTEIN SUBSTRATES

2 of 2

Ubrogepant also falls under P-GLYCOPROTEIN SUBSTRATES.

Theoretically, black pepper might increase levels of P-glycoprotein substrates.
In vitro research shows that piperine, a constituent of black pepper, seems to inhibit P-glycoprotein.
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 Ubrelvy (ubrogepant). Your body uses a pump called P-glycoprotein to help move this drug out of your system. Piperine, the active part of black pepper, can slow that pump down a bit. In theory, that means a little more ubrogepant could hang around in your blood, which might make side effects like nausea, sleepiness, or dry mouth a touch more noticeable.

But the key word is theoretical. This concern comes only from lab studies, not from real people, so the actual risk is likely small. Sprinkling pepper on your food is nothing to worry about. Concentrated piperine supplements (often paired with turmeric) are where I'd pause. If you take those regularly, just run it by your pharmacist or doctor first.

  • 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).

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.
