Cannabis and Atogepant

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

Why Are There 2 Interactions?

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

Theoretically, cannabis may increase the levels and adverse effects of CYP3A4 substrates.
In vitro research shows that cannabis can inhibit the activity of CYP3A4 enzymes, which might decrease the metabolism of CYP3A4 substrates. In vitro research also shows that cannabis extracts modestly inhibit the CYP3A4 metabolism of testosterone; extracts providing the specific cannabinoids CBD and cannabigerol (CBG) had stronger inhibitory effects than extracts containing THC and CBD.
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 for Qulipta (atogepant): your body relies on a liver enzyme called CYP3A4 to clear it. Lab studies suggest some cannabis compounds (especially CBD and CBG) can slow that enzyme down. If atogepant is cleared more slowly, more of it can hang around, which could nudge up its usual side effects like nausea, constipation, tiredness, or low appetite.

I want to be honest about how strong this is though. This is based only on test-tube research, not real people taking both together, so it's mostly theoretical. Atogepant is not a prodrug, so the worry is buildup, not lost benefit. Before mixing them, just check in with your pharmacist or doctor so they can keep an eye on how you feel.

P-GLYCOPROTEIN SUBSTRATES

2 of 2

Atogepant also falls under P-GLYCOPROTEIN SUBSTRATES.

Theoretically, cannabis might alter levels of drugs that are substrates of P-glycoprotein (P-gp).
Most in vitro research suggests that constituents of cannabis, including cannabidiol (CBD) and delta-9-tetrahydrocannabinol (THC), can inhibit P-gp and increase the accumulation of probe compounds by reducing P-gp mediated drug efflux. In vitro studies in kidney cell lines show that a 1-hour exposure to CBD and THC inhibits P-gp. Cannabis may also alter the expression of P-gp, although this effect appears to vary based on duration of exposure. Some in vitro research in lymphoblastoid leukemia cell lines indicates that a 1-hour exposure to cannabinoids does not affect P-gp expression, while a prolonged 72-hour exposure decreases P-gp expression. Other in vitro research in these cell lines shows that a 4-hour exposure to THC and CBD induces P-gp gene expression, while exposure for longer than 4 hours and up to 48 hours does not induce P-gp gene expression.
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 situation with Qulipta (atogepant) and cannabis. Atogepant is moved out of your cells by a kind of pump called P-glycoprotein (P-gp). Lab studies suggest cannabis compounds like THC and CBD can slow that pump down. If the pump works slower, a bit more atogepant could stay in your body, which in theory might bump up its usual side effects, things like nausea, constipation, tiredness, or feeling worn out.

I want to be honest about how soft this evidence is. It comes only from cells in a dish, not from people taking both together, so we really don't know if it matters in real life. Atogepant isn't a prodrug, so it still works normally. Still, it's worth a quick mention to your doctor or pharmacist, especially if you notice new drowsiness or stomach upset.

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.

This page covers Cannabis 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 Cannabis

What is Cannabis?

Cannabis
  • Chronic pain
  • Nausea and vomiting from chemotherapy
  • Muscle spasticity (e.g., multiple sclerosis)
  • Anxiety and stress
  • Sleep problems
  • Appetite stimulation

Cannabis contains many active compounds, mainly THC (which causes a 'high') and CBD (which does not). Some uses, such as chemotherapy-related nausea, certain seizure disorders, and muscle spasticity, have meaningful evidence, while many other popular uses are not well proven. It can cause real side effects and impairment, so talk to your doctor or pharmacist and follow your local laws before using it.

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.
