Rooibos and Atogepant

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

Moderate

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

Why this applies to Atogepant

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

Theoretically, taking rooibos with CYP3A4 substrates may increase the effects of CYP3A4 substrates.
In vitro research shows that the methanol extract of rooibos leaves and stems strongly inhibits CYP3A4 enzyme activity.
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 relies on a liver enzyme called CYP3A4 to clear atogepant (Qulipta) out of your system. Rooibos showed signs of blocking that enzyme, but only in lab dish experiments, not in real people. If that effect did carry over, your atogepant could clear a little slower and build up, which might mean more of its usual side effects like nausea, constipation, tiredness, or low appetite.

Here's my honest take: a normal cup or two of rooibos tea is very unlikely to cause a problem, since this concern comes from concentrated lab extracts. The bigger question is concentrated rooibos supplements or capsules. If you're using those, just run it by your pharmacist or doctor first to be safe.

See Every Supplement That Interacts With Atogepant

This page covers Rooibos only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Atogepant page lists 144 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Grapefruit (major), St. John's Wort (major), Acacia Rigidula (moderate) and Adrafinil (moderate).

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 Rooibos

What is Rooibos?

Rooibos
  • Caffeine-free beverage
  • Antioxidant support
  • Heart health
  • Blood sugar support
  • Digestive upset
  • General wellness

Rooibos is a caffeine-free herbal tea from South Africa that is rich in antioxidants and generally considered safe as a beverage. While lab and early studies suggest possible benefits for heart health, blood sugar, and inflammation, strong human evidence is lacking for most medical uses. Enjoy it as a tea, but talk to your pharmacist or doctor before using concentrated extracts for health reasons.

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.
