Drug & supplement interaction

Avocado + Duvelisib

Duvelisib brand name: Copiktra.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 20, 2026
The bottom line No known interaction

We found no known interaction between Avocado and Duvelisib in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first. Additionally, although there is no interaction, the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

Avocado and Duvelisib

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Duvelisib and Avocado in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

How we checked

Why No Interaction Is Listed for Duvelisib

Interactions in our licensed database are recorded against drug classes, not just single drug names. Duvelisib is filed under 3 classifications — cytochrome p450 3a4 (cyp3a4) inhibitors, cytochrome p450 3a4 (cyp3a4) substrates, oral drugs. Avocado has documented interactions with 1 drug class — the most serious being warfarin (coumadin) (moderate) — and none of Duvelisib’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

What to actually watch for

No Interaction Found — But Data Suggests Avocado and Duvelisib May Share Several of the Same Side Effects

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do. One of them is worth acting on rather than waiting out — marked below.

  • A higher chance of infection Worth acting on reported in 5.4% of FDA reports for Duvelisib Additional detail

    Avocado

    “Orally, avocado can cause acute food protein-induced enterocolitis syndrome (FPIES). This is a rare, delayed, non-IgE-mediated gastrointestinal food hypersensitivity reaction most often reported in infants and young children. Symptoms of FPIES include excessive vomiting within 1-4 hours of avocado consumption and diarrhea.”

Reported for Avocado but not commonly for Duvelisib: an allergic reaction, stomach upset, bloating or gas and itching.

Effects for Duvelisib come from the ADVERSE REACTIONS section of its FDA label; effects for Avocado come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 765 voluntary FDA FAERS reports for Duvelisib that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

See Every Supplement That Interacts With Duvelisib

This page covers Avocado only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Duvelisib page lists 143 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 · 100 moderate · 40 minor.

From our pharmacist’s overview on the Duvelisib page

“Duvelisib (Copiktra) treats certain blood cancers, and its supplement list deserves genuine care because the body clears it through a single enzyme, CYP3A4. Most of the 143 ingredients either block or speed up that enzyme, which can push duvelisib levels high enough to worsen side effects or low enough to weaken its grip on the cancer.”

About Avocado

What is Avocado?

Avocado
  • Heart and cholesterol health
  • Osteoarthritis (as ASU)
  • General nutrition and healthy fats
  • Skin and hair care
  • Blood sugar support

Avocado is a nutritious fruit rich in healthy monounsaturated fats, fiber, and potassium, and eating it as part of a balanced diet may support heart health. A specific extract called avocado/soybean unsaponifiables (ASU) has been studied for osteoarthritis, but evidence is mixed. As a food it is very safe for most people; talk to your pharmacist or doctor before using concentrated supplements.

Persea americana · Lauraceae · Fruit pulp, oil, seed, and leaves · Whole fruit, avocado oil, capsules (avocado/soybean unsaponifiables or ASU), powders

An interaction check asks whether these two react with each other — it does not ask whether Avocado is a good idea for someone in your situation. Here is what our Avocado record says about it on its own.

Avocado: dosing

There is no official standardized dose of avocado, since it is mainly eaten as a food. A common serving is part of a whole fruit, eaten as part of a balanced diet.For supplements such as ASU, the right amount depends on the specific product, so it is best to follow the directions on the label.

Copiktra (duvelisib) is used in adults with relapsed or refractory chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) — meaning the cancer has returned or stopped responding to treatment — after at least two prior therapies.

Copiktra is also used for relapsed or refractory follicular lymphoma (FL) after at least two prior systemic therapies. The follicular lymphoma approval is based on overall response rate and is considered an accelerated approval; continued approval may depend on results from confirmatory trials. Copiktra is not intended for use as a first- or second-line treatment for any of these cancers.

Taking Avocado and Duvelisib Together: Common Questions

Is it safe to take Avocado with Duvelisib?
We do not list a known interaction between Avocado and Duvelisib. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Do Avocado and Duvelisib have any of the same side effects?
Yes — our sources link each of them separately to 4 of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.
How was the Avocado and Duvelisib combination checked?
Interactions in our licensed database are recorded against drug classes. Duvelisib is filed under 3 classifications, and Avocado has documented interactions with 1 drug class — none of Duvelisib's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
Does Avocado interact with any other medications?
Yes. Avocado has 2 documented drug interactions in our database — Duvelisib is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Duvelisib interact with any supplements?
Yes. Duvelisib has documented interactions with 143 supplements in our database — Avocado is not one of them. The Duvelisib interaction page linked on this page lists every one, ranked by severity.
