The bottom line No known interaction

We found no known interaction between Monolaurin 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.

Monolaurin 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 Monolaurin 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 Monolaurin 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.

What Duvelisib’s Own FDA Label Lists

This is not an interaction — none of it involves Monolaurin. These are the most notable effects listed in the ADVERSE REACTIONS section of Duvelisib’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both. 10 of them are worth acting on rather than waiting out — marked below.

  • High potassium Worth acting on
  • Low sodium Worth acting on
  • Low potassium Worth acting on
  • A severe skin reaction Worth acting on
  • A low platelet count Worth acting on
  • Anemia Worth acting on
  • Shortness of breath Worth acting on
  • A low white blood cell count Worth acting on
  • Liver problems Worth acting on
  • A higher chance of infection Worth acting on mentioned in 5.4% of FDA reports for Duvelisib

Showing the 10 most notable of 25 label-listed effects — ranked by how unusual each one is across medicines generally, with serious effects weighted up.

From the ADVERSE REACTIONS section of the FDA label for Duvelisib. Read the label on DailyMed › 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. Monolaurin’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Monolaurin side to compare — that is a limit of the record, not a statement that Monolaurin has no side effects.

See Every Supplement That Interacts With Duvelisib

This page covers Monolaurin 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 Monolaurin

What is Monolaurin?

Monolaurin
  • Immune support
  • Viral infections (such as herpes or colds)
  • Antibacterial support
  • Yeast and fungal concerns
  • General antimicrobial use

Monolaurin is a compound made from lauric acid, a fatty acid found in coconut oil and breast milk, and it is marketed mostly for immune and antimicrobial support. While laboratory studies suggest it can disrupt certain bacteria, viruses, and fungi, strong human evidence is lacking, so its real-world benefits remain unproven. Talk with your pharmacist or doctor before using it, especially if you are pregnant, breastfeeding, or have a health condition.

Derived from lauric acid (a fatty acid from coconut oil and palm kernel oil) · Capsules, tablets, pellets/beads, powder

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

Monolaurin: dosing

There is no officially established or standardized dose for monolaurin. Studies have used different amounts, and there is no strong human evidence to recommend a specific dose for any condition.Because products vary widely in strength and form, the best approach is to follow the directions on the product label and not exceed the suggested amount. They can help you decide whether it is appropriate for you.

What Is Duvelisib Used For?

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.
