Drug & supplement interaction

Gluten-free Diet + 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 Gluten-free Diet 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.

Gluten-free Diet 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 Gluten-free Diet in our sources. This does not guarantee that the combination is completely free of risk — research on Gluten-free Diet alongside specific medications may be limited.

Worth understanding: our licensed dataset holds no drug-interaction record for Gluten-free Diet 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.

Gluten-free Diet is an eating pattern rather than something you take. Ask your pharmacist or doctor before changing how you eat while on a prescribed medicine: some medicines are dosed around meals, and a change in diet can change how they work. 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.

Gluten-free Diet safety at a glance

Gluten-free Diet overall Use caution Generally safe for those who need it, but can lower fiber and certain nutrients if not well planned.
Pregnancy Generally safe Appropriate and important during pregnancy for people with celiac disease, ideally with dietitian support.
Breastfeeding Generally safe A medically needed gluten-free diet is fine while breastfeeding; aim for balanced nutrition.

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

What to actually watch for

No Interaction Found — But Data Suggests Gluten-free Diet and Enzalutamide 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 following Gluten-free Diet while taking the medicine can make those effects more likely to turn up, and harder to pin on one or the other if they do.

  • Anxiety or restlessness Additional detail

    Gluten-free Diet

    “Some research reports iron deficiency (anemia), malnutrition, anxiety and depression in people using the gluten free diet; however causality of these symptoms is unclear.”

    Gluten-free Diet · Natural Medicines adverse-effect record, reported in anemia.

    Enzalutamide

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

Reported for Gluten-free Diet but not commonly for Enzalutamide: low mood and anemia.

Effects for Enzalutamide come from the ADVERSE REACTIONS section of its FDA label; effects for Gluten-free Diet 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.

Where does our data come from?
  • Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. Gluten-free Diet is not yet covered by that licensed database, so its write-up cites publicly available medical sources directly (see the references below).
  • Citation library: 103,510 references behind our interaction content, 65,311 of them resolved to verified PubMed/DOI sources. See every Gluten-free Diet reference on this page ↓
  • Freshness: we automatically re-check this combination every week — this pair was last verified September 20, 2026. The Gluten-free Diet and Enzalutamide records this page draws on were last updated July 10, 2026.
  • What “no known interaction” means: no documented interaction in the sources above — not a guarantee of safety. Supplements are studied far less than prescription drugs, so we say exactly what the evidence supports, and nothing more.

About Gluten-free Diet

What is Gluten-free Diet?

  • Celiac disease
  • Non-celiac gluten sensitivity
  • Wheat allergy
  • Dermatitis herpetiformis
  • Digestive symptoms like bloating or diarrhea

A gluten-free diet removes wheat, barley, rye, and related grains. It is the proven, necessary treatment for celiac disease and dermatitis herpetiformis, and it helps some people with wheat allergy or non-celiac gluten sensitivity. For people without these conditions, there is no strong evidence that going gluten-free improves health, so talk with your doctor before making big diet changes.

Whole-food eating pattern; gluten-free packaged foods, flours, and breads

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

Gluten-free Diet: dosing

A gluten-free diet is not a pill, so there is no "dose." Instead, the goal for people who need it is to completely avoid gluten from wheat, barley, rye, and related grains, including hidden sources in sauces, processed foods, and even some medicines and supplements.Look for products labeled certified gluten-free, and read ingredient lists carefully. Working with a registered dietitian is the best way to follow the diet correctly while keeping your nutrition balanced.

About Enzalutamide

What Is Enzalutamide Used For?

Brand name: Xtandi

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.

Most-Reported Side Effects for Enzalutamide

From FAERS, the FDA’s public side-effect reporting system (58,437 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Fatigue 10,267 reports
Malignant neoplasm progression 5,468 reports
Prostatic specific antigen increased 4,344 reports
Asthenia 4,171 reports
Hot flush 3,882 reports

Following Gluten-free Diet While Taking Enzalutamide: Common Questions

Is it safe to follow Gluten-free Diet while taking Enzalutamide?

Do Gluten-free Diet and Enzalutamide 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.

Does Enzalutamide interact with any supplements?
Yes. Enzalutamide has documented interactions with 49 supplements in our database — Gluten-free Diet is not one of them. The Enzalutamide interaction page linked on this page lists every one, ranked by severity.
