Drug & supplement interaction

Raspberry Ketone + Lurbinectedin

Lurbinectedin brand name: Zepzelca.

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 Raspberry Ketone and Lurbinectedin 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.

Raspberry Ketone and Lurbinectedin

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 Lurbinectedin and Raspberry Ketone 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.

Raspberry Ketone safety at a glance

Raspberry Ketone overall Use caution Used in foods safely, but human safety data for high supplement doses is very limited.
Pregnancy Avoid Not enough safety information; avoid concentrated supplements during pregnancy.
Breastfeeding Avoid Not enough safety information; avoid supplement use while breastfeeding.

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

How we checked

Why No Interaction Is Listed for Lurbinectedin

Interactions in our licensed database are recorded against drug classes, not just single drug names. Lurbinectedin is filed under 3 classifications — alkylating agents, hepatotoxic drugs, cytochrome p450 3a4 (cyp3a4) substrates. Raspberry Ketone has documented interactions with 2 drug classes — the most serious being stimulant drugs (moderate) and warfarin (coumadin) (moderate) — and none of Lurbinectedin’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.

No Interaction Found — But Data Suggests Raspberry Ketone and Lurbinectedin 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.

  • Diarrhea Additional detail

    Raspberry Ketone

    “Structurally, raspberry ketone resembles synephrine, a known stimulant agent. Although not well studied in humans, stimulant-related side effects are possible. Two case reports describe symptoms of sweating, diarrhea, and feelings of shakiness after oral use of raspberry ketone.”

About Raspberry Ketone

What is Raspberry Ketone?

Raspberry Ketone
  • Weight loss
  • Fat burning
  • Boosting metabolism
  • Appetite support
  • General 'fat-burner' supplement

Raspberry ketone is a natural aroma compound found in red raspberries that is heavily marketed for weight loss, but there is no good human evidence that it helps people lose weight. Most claims come from lab and animal studies using doses far higher than what you could get from food or typical supplements. If you choose to try it, talk to your pharmacist or doctor first.

Fruit-derived aromatic compound (4-(4-hydroxyphenyl)butan-2-one) · Capsules, tablets, softgels, powders, often combined with other weight-loss ingredients

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

Raspberry Ketone: dosing

There is no established or proven effective dose of raspberry ketone for weight loss or any other use. The amounts found in supplements vary widely from product to product.If you decide to try it, follow the directions on the product label and do not take more than recommended. Because supplements are not tightly regulated, the actual amount in a product may differ from what is listed, and quality can vary between brands.Before starting, it is a good idea to review the full ingredient list with your pharmacist, especially since many products contain caffeine or other added stimulants.

About Lurbinectedin Injection

What Is Lurbinectedin Injection Used For?

Brand name: Zepzelca

Zepzelca (lurbinectedin) injection is approved for adults with small cell lung cancer (SCLC) in two settings. First, Zepzelca is used in combination with atezolizumab (or atezolizumab and hyaluronidase-tqjs) as maintenance treatment for extensive-stage small cell lung cancer (ES-SCLC) in patients whose disease did not progress after initial treatment with those same immunotherapy drugs plus carboplatin and etoposide.

Second, Zepzelca is approved as a single agent for adults with metastatic small cell lung cancer whose cancer has worsened during or after platinum-based chemotherapy. This second use was granted accelerated approval based on tumor response rates, and continued approval depends on results from confirmatory clinical trials.

Taking Raspberry Ketone and Lurbinectedin Together: Common Questions

Is it safe to take Raspberry Ketone with Lurbinectedin?
We do not list a known interaction between Raspberry Ketone and Lurbinectedin. 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 Raspberry Ketone and Lurbinectedin 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.
How was the Raspberry Ketone and Lurbinectedin combination checked?
Interactions in our licensed database are recorded against drug classes. Lurbinectedin is filed under 3 classifications, and Raspberry Ketone has documented interactions with 2 drug classes — none of Lurbinectedin'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 Raspberry Ketone interact with any other medications?
Yes. Raspberry Ketone has 174 documented drug interactions in our database — Lurbinectedin 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 Lurbinectedin interact with any supplements?
Yes. Lurbinectedin has documented interactions with 156 supplements in our database — Raspberry Ketone is not one of them. The Lurbinectedin interaction page linked on this page lists every one, ranked by severity.
