Drug & supplement interaction

Lactobacillus Delbrueckii + Enzalutamide

Enzalutamide brand name: Xtandi.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between Lactobacillus Delbrueckii 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.

Interaction report

Lactobacillus Delbrueckii 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 Lactobacillus Delbrueckii 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.

Lactobacillus Delbrueckii safety at a glance

Lactobacillus Delb... overall Use caution Generally well tolerated in healthy people, but people who are very ill or immunocompromised should be cautious.
Pregnancy Use caution Probiotics in food are likely fine, but supplement safety in pregnancy is not well studied, so check with your doctor.
Breastfeeding Use caution Limited specific data, so use only with guidance from your healthcare provider.

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

How we checked

Why No Interaction Is Listed for Enzalutamide

Interactions in our licensed database are recorded against drug classes, not just single drug names. Enzalutamide is filed under 6 classifications — including cytochrome p450 2c9 (cyp2c9) inducers, cytochrome p450 2c19 (cyp2c19) inducers, cytochrome p450 3a4 (cyp3a4) inducers. Lactobacillus Delbrueckii has documented interactions with 1 drug class — the most serious being antibiotic drugs (moderate) — and none of Enzalutamide’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 Lactobacillus Delbrueckii 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 taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do. One of them is worth acting on rather than waiting out — marked below.

  • A higher chance of infection Worth acting on Additional detail

    Lactobacillus Delbrueckii

    “Since Lactobacillus delbrueckii preparations contain live and active microorganisms, there is some concern that they might cause pathogenic infection in some patients. Some lactobacilli species have been isolated in cases of bacteremia, sepsis, splenic abscess, endocarditis, necrotizing fasciitis, pancreatic necrosis, and meningoencephalitis.”

    Enzalutamide

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

Reported for Lactobacillus Delbrueckii but not commonly for Enzalutamide: trouble passing urine.

Effects for Enzalutamide come from the ADVERSE REACTIONS section of its FDA label; effects for Lactobacillus Delbrueckii 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.

About Lactobacillus Delbrueckii

What is Lactobacillus Delbrueckii?

  • Digestive health
  • Lactose digestion support
  • Diarrhea
  • Gut microbiome balance
  • Immune support

Lactobacillus delbrueckii is a 'friendly' bacterium used in food fermentation and sold as a probiotic, often as part of multi-strain products. It is generally considered safe for healthy people, but solid human evidence for most specific health claims is limited. Talk to a pharmacist or doctor before using it, especially if you have a weakened immune system or serious illness.

Lactobacillus delbrueckii · Lactobacillaceae · Live bacterial cultures (the whole microorganism) · Capsules, tablets, powders, fermented dairy products (yogurt, cheese), and multi-strain probiotic blends

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

Lactobacillus Delbrueckii: dosing

There is no standardized, official dose of Lactobacillus delbrueckii. Probiotic products are usually measured in colony-forming units (CFU), and the amount varies widely between products.The best approach is to follow the directions on the product label and not exceed the recommended amount. Storing the product as directed (some need refrigeration) helps keep the bacteria alive and effective.

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

Taking Lactobacillus Delbrueckii and Enzalutamide Together: Common Questions

Is it safe to take Lactobacillus Delbrueckii with Enzalutamide?
We do not list a known interaction between Lactobacillus Delbrueckii 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 Lactobacillus Delbrueckii 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. 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 Lactobacillus Delbrueckii and Enzalutamide combination checked?
Interactions in our licensed database are recorded against drug classes. Enzalutamide is filed under 6 classifications, and Lactobacillus Delbrueckii has documented interactions with 1 drug class — none of Enzalutamide'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 Lactobacillus Delbrueckii interact with any other medications?
Yes. Lactobacillus Delbrueckii has 182 documented drug interactions in our database — Enzalutamide 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 Enzalutamide interact with any supplements?
Yes. Enzalutamide has documented interactions with 49 supplements in our database — Lactobacillus Delbrueckii is not one of them. The Enzalutamide interaction page linked on this page lists every one, ranked by severity.
