Drug & supplement interaction

Durian + Lapatinib

Lapatinib brand name: Tykerb.

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 Durian and Lapatinib 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.

Durian and Lapatinib

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 Lapatinib and Durian 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.

Durian safety at a glance

Durian overall Use caution Generally safe as a food in moderation, but high in sugar and calories.

Breastfeeding Use caution Likely fine in normal food amounts, but data on supplements is lacking.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Lapatinib

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

  • Diarrhea / Vomiting reported in 27.1% of FDA reports for Lapatinib Additional detail

    Durian

    “A case report describes a patient who experienced abdominal discomfort and flatulence after eating durian fruit along with alcohol. There has also been a case report of a patient experiencing diarrhea and vomiting after eating durian.”

    Lapatinib

    Listed in the ADVERSE REACTIONS section of the FDA label for Lapatinib, and in voluntary FDA adverse-event reports. Read the label on DailyMed ›

Reported for Durian but not commonly for Lapatinib: stomach upset, an allergic reaction, a stuffy or runny nose and bloating or gas.

Effects for Lapatinib come from the ADVERSE REACTIONS section of its FDA label; effects for Durian come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 15,427 voluntary FDA FAERS reports for Lapatinib 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.

Everything else you take

See Every Supplement That Interacts With Lapatinib

This page covers Durian only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Lapatinib 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 Lapatinib page

“Of the 143 supplements on file for lapatinib (Tykerb), nearly all press on the same point, the CYP3A4 enzyme that clears this HER2-targeted breast cancer drug. That deserves real caution, since lapatinib only works when its blood level stays in range.”

About Durian

What is Durian?

  • General nutrition and energy
  • Traditional tonic or aphrodisiac
  • Digestive support
  • Source of antioxidants
  • Fever and traditional folk remedies

Durian is a popular tropical fruit valued mainly as a nutritious food rich in carbohydrates, fiber, vitamins, and antioxidants. While it has many traditional medicinal uses, there is little solid human research to support health claims beyond basic nutrition, and it is very high in calories. Enjoy it as a food in moderation, and check with your doctor or pharmacist if you have diabetes or other health concerns.

Durio zibethinus · Malvaceae · Fruit (pulp and seeds); rind, leaves, and roots in traditional medicine · Fresh fruit, frozen pulp, dried snacks, powder, capsules, candy, and flavorings

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

Durian: dosing

There is no established medicinal dose for durian. As a food, a small serving of the pulp is typical, and because it is high in calories and sugar, moderation is wise.For any durian supplement, powder, or extract product, follow the directions on the label.

Taking Durian and Lapatinib Together: Common Questions

Is it safe to take Durian with Lapatinib?
We do not list a known interaction between Durian and Lapatinib. 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 Durian and Lapatinib have any of the same side effects?
Yes — our sources link each of them separately to 2 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 Durian and Lapatinib combination checked?
Interactions in our licensed database are recorded against drug classes. Lapatinib is filed under 3 classifications, and Durian has documented interactions with 1 drug class — none of Lapatinib'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 Durian interact with any other medications?
Yes. Durian has 1 documented drug interaction in our database — Lapatinib 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 Lapatinib interact with any supplements?
Yes. Lapatinib has documented interactions with 143 supplements in our database — Durian is not one of them. The Lapatinib interaction page linked on this page lists every one, ranked by severity.
