Drug & supplement interaction

Cucumber + Flutamide

Flutamide brand names: Eulexin, Euflex.

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 Cucumber and Flutamide 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

Cucumber and Flutamide

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 Flutamide and Cucumber 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.

Cucumber safety at a glance

Cucumber overall Generally safe Cucumber is widely eaten as a food and is generally well tolerated by most people.
Pregnancy Use caution Cucumber as a food is fine, but concentrated supplements or extracts have not been studied in pregnancy.
Breastfeeding Use caution Eating cucumber is considered fine; safety of concentrated extracts while breastfeeding is unknown.

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

How we checked

Why No Interaction Is Listed for Flutamide

Interactions in our licensed database are recorded against drug classes, not just single drug names. Flutamide is filed under 7 classifications — including cytochrome p450 1a2 (cyp1a2) substrates, cytochrome p450 1a2 (cyp1a2) substrates, photosensitizing drugs. Cucumber has documented interactions with 1 drug class — the most serious being antidiabetes drugs (moderate) — and none of Flutamide’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 Cucumber and Flutamide 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.

  • Vomiting Additional detail

    Cucumber

    “Orally, anaphylaxis with dizziness, vomiting, trouble breathing, and itching, occurring 5 minutes after eating a partially peeled cucumber, has been reported in a 76-year-old woman.

    Topically, allergic eczema related to exposure to cucumber leaves and stems has been reported in a greenhouse worker.”

    Flutamide

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

Reported for Cucumber but not commonly for Flutamide: shortness of breath, a severe allergic reaction, dizziness and itching.

Effects for Flutamide come from the ADVERSE REACTIONS section of its FDA label; effects for Cucumber come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 984 voluntary FDA FAERS reports for Flutamide 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 Flutamide

This page covers Cucumber only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Flutamide page lists 189 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 · 143 moderate · 43 minor.

From our pharmacist’s overview on the Flutamide page

“A man taking flutamide (Eulexin) to block testosterone during prostate cancer treatment cannot afford big swings in the drug's level, and most of the 189 supplements on this page are capable of causing exactly that. The bulk of them work through the liver enzyme CYP3A4, which breaks flutamide down.”

About Cucumber

What is Cucumber?

  • Hydration and skin care
  • Cooling and soothing puffy eyes
  • Mild diuretic effect
  • Antioxidant support
  • Digestive comfort

Cucumber is a common food vegetable that is mostly water and is generally safe to eat. As a supplement or skincare ingredient it is popular for hydration and soothing the skin, but solid human research showing health benefits beyond basic nutrition is limited.

Cucumis sativus · Cucurbitaceae · Fruit, seeds, and seed extract · Fresh fruit, juice, seed extract capsules, topical creams and slices, water infusions

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

Cucumber: dosing

There is no established or standardized supplement dose for cucumber. As a food, you can simply enjoy it in normal amounts as part of a balanced diet.If you choose a cucumber supplement, extract, or skincare product, follow the directions on the product label.

About Flutamide

What Is Flutamide Used For?

Brand names: Eulexin, Euflex

Eulexin (flutamide) capsules are used to treat prostate cancer in men. They are always used together with an LHRH agonist (a hormone-lowering injection), never alone.

Eulexin is indicated for two stages of prostate cancer: locally confined Stage B2-C prostate cancer (used alongside goserelin acetate and radiation therapy, starting eight weeks before radiation begins) and Stage D2 metastatic prostate cancer (cancer that has spread beyond the prostate, taken with an LHRH agonist until the disease progresses).

Most-Reported Side Effects for Flutamide

From FAERS, the FDA’s public side-effect reporting system (984 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Prostate cancer 70 reports
Anemia 65 reports
Fatigue 63 reports
Prostatic specific antigen increased 60 reports
Asthenia 46 reports

Taking Cucumber and Flutamide Together: Common Questions

Is it safe to take Cucumber with Flutamide?
We do not list a known interaction between Cucumber and Flutamide. 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 Cucumber and Flutamide 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 Cucumber and Flutamide combination checked?
Interactions in our licensed database are recorded against drug classes. Flutamide is filed under 7 classifications, and Cucumber has documented interactions with 1 drug class — none of Flutamide'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 Cucumber interact with any other medications?
Yes. Cucumber has 86 documented drug interactions in our database — Flutamide 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 Flutamide interact with any supplements?
Yes. Flutamide has documented interactions with 189 supplements in our database — Cucumber is not one of them. The Flutamide interaction page linked on this page lists every one, ranked by severity.
