Drug & supplement interaction

Lauric Acid + 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 Lauric Acid 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.

Interaction report

Lauric Acid 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 Lauric Acid 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.

Worth understanding: our licensed dataset holds no drug-interaction record for Lauric Acid at all — not against Duvelisib, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

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.

No Interaction Found — But Data Suggests Lauric Acid and Duvelisib May Share a Side Effect

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.

  • Nausea reported in 6.4% of FDA reports for Duvelisib Additional detail

    Lauric Acid

    “Orally, nausea appears to be fairly common when lauric acid is infused into the duodenum at a rate of 0.4 kcal/minute or faster. The rate of nausea with oral administration is unknown.”

Effects for Duvelisib come from the ADVERSE REACTIONS section of its FDA label; effects for Lauric Acid 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.

Lauric Acid in Pregnancy & Breastfeeding

Pregnancy And Lactation Likely Safe

When used orally in amounts commonly found in foods. There is insufficient reliable information available about the safety of lauric acid when used in medicinal amounts during pregnancy or lactation. Dietary lauric acid is excreted into breast milk.

See Every Supplement That Interacts With Duvelisib

This page covers Lauric Acid 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 Lauric Acid

What is Lauric Acid?

  • Antimicrobial support
  • Skin care and acne
  • Heart and cholesterol concerns
  • Immune support
  • Energy and weight management

Lauric acid is a medium-to-long-chain saturated fatty acid found in coconut oil, palm kernel oil, and breast milk. It is studied for possible antimicrobial and skin benefits, but solid human evidence for most supplement uses is limited. As part of a normal diet it is generally fine; talk to your pharmacist or doctor before using high-dose supplements.

Fatty acid found mainly in coconut oil and palm kernel oil; also present in human breast milk · Coconut oil, MCT products, capsules, monolaurin supplements, topical products, soaps

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

Lauric Acid: dosing

There is no official or standardized dose of lauric acid as a supplement. Amounts vary widely between products, including coconut oil, MCT blends, and monolaurin capsules.If you choose to use a lauric acid or monolaurin product, follow the directions on the label and do not assume more is better.

What Is Duvelisib Used For?

Brand name: Copiktra

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.

Most-Reported Side Effects for Duvelisib

From FAERS, the FDA’s public side-effect reporting system (765 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Taking Lauric Acid and Duvelisib Together: Common Questions

Is it safe to take Lauric Acid with Duvelisib?
We do not list a known interaction between Lauric Acid 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 Lauric Acid and Duvelisib have any of the same side effects?
Yes — our sources link each of them separately to one 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.
Does Duvelisib interact with any supplements?
Yes. Duvelisib has documented interactions with 143 supplements in our database — Lauric Acid is not one of them. The Duvelisib interaction page linked on this page lists every one, ranked by severity.
