Drug & supplement interaction

Tomato + Enzalutamide

Enzalutamide brand name: Xtandi.

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 Tomato and Enzalutamide 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.

Tomato and Enzalutamide

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 Enzalutamide and Tomato 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 Tomato at all — not against Enzalutamide, 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 to actually watch for

No Interaction Found — But Data Suggests Tomato and Enzalutamide 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.

  • Dizziness / Headache Additional detail

    “Orally, the glycoalkaloid tomatine in tomato leaf or green tomatoes can cause dizziness, stupor, headache, and mild spasms when consumed in excessive amounts (18,102957).”

    Listed in the ADVERSE REACTIONS section of the FDA label for Enzalutamide. Read the label on DailyMed ›

Reported for Tomato but not commonly for Enzalutamide: a slow heartbeat.

Effects for Enzalutamide come from the ADVERSE REACTIONS section of its FDA label; effects for Tomato come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 58,437 voluntary FDA FAERS reports for Enzalutamide 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.

Overlapping uses

What Enzalutamide Is Prescribed For, and What Tomato Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Enzalutamide is a prescription medicine with approved uses on its FDA label. Tomato is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Enzalutamide is prescribed for: Xtandi (enzalutamide) is used to treat prostate cancer in three specific situations: castration-resistant prostate cancer (CRPC), metastatic castration-sensitive prostate cancer (mCSPC), and non-metastatic castration-sensitive prostate cancer with biochemical recurrence at high risk for metastasis (high-risk BCR). Castration-resistant means the cancer has continued to grow despite low testosterone levels. Castration-sensitive means the cancer still responds to testosterone-lowering therapy. In most of these cases, Xtandi is used alongside a GnRH analog (a hormone-lowering injection) or after surgical removal of the testicles — except in the high-risk BCR setting, where it may be used with or without a GnRH analog.

Tomato has been studied for:

  • Prostate cancer studied, not established Tomato has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Tomato for prostate cancer

    Consuming tomatoes or tomato-based products may slightly lower the risk of prostate cancer; however, observational research is mixed and high-quality clinical trials addressing tomato intake and prostate cancer risk are lacking.

Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Enzalutamide on your own; if you are taking Tomato for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

About Tomato

What is Tomato?

  • Heart health support
  • Prostate health
  • Antioxidant support
  • Skin protection from sun damage
  • General nutrition

Tomato is a common food rich in vitamins, potassium, and the antioxidant lycopene, and eating it as part of a balanced diet is healthy for most people. Concentrated tomato or lycopene supplements are marketed for heart and prostate health, but the evidence is mixed and far from proven. Talk to your pharmacist or doctor before using high-dose supplements, especially if you are pregnant or have a medical condition.

Solanum lycopersicum · Solanaceae · Fruit (and extracts such as lycopene from the fruit and skin) · Whole fruit, juice, paste, tomato extract capsules, lycopene supplements

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

Tomato: dosing

There is no official standardized dose of tomato or lycopene supplements, and a proven effective amount has not been established. Tomatoes are best enjoyed simply as part of a balanced diet.If you choose to use a tomato extract or lycopene supplement, follow the directions on the product label and do not exceed the recommended amount.

Taking Tomato and Enzalutamide Together: Common Questions

Is it safe to take Tomato with Enzalutamide?
We do not list a known interaction between Tomato and Enzalutamide. 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 Tomato and Enzalutamide 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.
Are Tomato and Enzalutamide used for the same thing?
They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together. This page lists the shared uses and how strong the evidence is for Tomato in each. That is a conversation for your prescriber, especially if Enzalutamide is being adjusted to a target.
Does Enzalutamide interact with any supplements?
Yes. Enzalutamide has documented interactions with 49 supplements in our database — Tomato is not one of them. The Enzalutamide interaction page linked on this page lists every one, ranked by severity.
