Uva Ursi and Atogepant

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

Why Are There 2 Interactions?

Uva Ursi interacts with whole categories of medication. Atogepant falls into 2 of those categories, so it can interact with Uva Ursi 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 Atogepant

Atogepant falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES — the group Uva Ursi interacts with.

Theoretically, uva ursi may decrease the metabolism of CYP3A4 substrates.
In vitro, uva ursi appears to inhibit CYP3A4. 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: your migraine medicine atogepant (Qulipta) is cleared from your body mainly by a liver enzyme called CYP3A4. In lab dishes, uva ursi seems to slow that same enzyme down. If that held true in real people, your body might break down atogepant more slowly, letting more of it build up. That could mean stronger effects and a better chance of side effects like nausea, constipation, tiredness, or sleepiness.

The reassuring part is that this is only a test-tube finding and hasn't been seen in actual patients, so it's theoretical. Still, since uva ursi is meant for short-term use anyway and can stress the liver, it's worth a quick chat with your pharmacist or doctor before combining the two.

P-GLYCOPROTEIN SUBSTRATES

2 of 2

Atogepant also falls under P-GLYCOPROTEIN SUBSTRATES.

Theoretically, uva ursi may alter the levels of drugs transported by P-glycoprotein.
In vitro, uva ursi appears to inhibit the multi-drug transporter protein, P-glycoprotein. This effect has not been reported in humans.
Severity Minor 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 atogepant (Qulipta), your migraine prevention medicine. Atogepant rides through the gut on a transporter called P-glycoprotein, which acts like a doorman controlling how much gets absorbed. In test-tube studies, uva ursi seems to slow that doorman down. If that happened in real life, slightly more atogepant could get into your bloodstream, which might bump up its usual side effects like nausea, constipation, tiredness, or low appetite.

The important part: this is only seen in lab studies, not in actual people, and it's rated as a minor, theoretical concern. So I wouldn't lose sleep over it. Still, since uva ursi is meant for short-term use only, it's worth a quick chat with your pharmacist or doctor before combining them.

  • 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.

By severity: 3 major · 103 moderate · 38 minor.

From our pharmacist’s overview on the Atogepant page

“Grapefruit is the single interaction I would want every Qulipta user to know first. Atogepant, a preventive migraine medicine, is cleared by a liver enzyme called CYP3A4, and grapefruit juice blocks that enzyme, so the drug can build up and side effects become more likely.”

About Uva Ursi

What is Uva Ursi?

Uva Ursi
  • Urinary tract infections
  • Urinary discomfort
  • Mild diuretic
  • Kidney stones
  • Skin conditions

Uva ursi is a traditional herb used mainly for urinary tract infections, and its leaves contain a compound called arbutin that may have antimicrobial effects in the urine. Evidence in people is limited, and because high doses or long-term use may be harmful to the liver and could be toxic, it should only be used short-term and with guidance from a healthcare professional. Avoid it during pregnancy and breastfeeding.

About Atogepant

What Is Atogepant Used For?

Brand name: Qulipta

Qulipta (atogepant) is used to prevent migraines in adults — both episodic migraine (fewer monthly migraine days) and chronic migraine (15 or more headache days a month). It is a preventive treatment, meaning you take it regularly to reduce how often migraines happen, not to stop a migraine that has already started.
