Brewer's Yeast + Dalbavancin Hydrochloride

Dalbavancin Hydrochloride brand name: Dalvance.

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 Brewer's Yeast and Dalbavancin Hydrochloride 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

Brewer's Yeast and Dalbavancin Hydrochloride

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 Dalbavancin Hydrochloride and Brewer's Yeast 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.

Brewer's Yeast safety at a glance

Brewer's Yeast overall Use caution Generally well tolerated in food amounts, but it can cause gas and may not be safe for people with weakened immune systems or certain conditions.
Pregnancy Use caution Likely fine in normal food amounts, but the safety of concentrated supplements during pregnancy is not well studied, so check with your provider.
Breastfeeding Use caution Food amounts are likely fine, but there is not enough information on supplement doses, so use caution and ask your provider.

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

How we checked

Why No Interaction Is Listed for Dalbavancin Hydrochloride

Interactions in our licensed database are recorded against drug classes, not just single drug names. Dalbavancin Hydrochloride is filed under a single classification — antibiotic drugs. Brewer's Yeast has documented interactions with 4 drug classes — the most serious being monoamine oxidase inhibitors (maois) (major), antidiabetes drugs (moderate) and lithium (moderate) — and none of Dalbavancin Hydrochloride’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 Brewer's Yeast and Dalbavancin Hydrochloride 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. 3 of them are worth acting on rather than waiting out — marked below.

  • A severe allergic reaction Worth acting on Additional detail

    Brewer's Yeast

    “Allergic reactions to brewer's yeast can occur in hypersensitive individuals. Symptoms include itching, urticaria, local or general exanthemas, and Quincke's edema (2). Rarely, anaphylaxis may occur. In one case, a 33-year-old male experienced dyspnea, chest tightness, and throat tightness shortly after ingesting a few sips of craft beer brewed using brewer's yeast.”

See Every Supplement That Interacts With Dalbavancin Hydrochloride

This page covers Brewer's Yeast only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Dalbavancin Hydrochloride page lists 27 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Bacillus Coagulans (moderate), Bacillus Subtilis (moderate), Bifidobacterium Animalis Subsp. Lactis (moderate), Bifidobacterium Bifidum (moderate) and Bifidobacterium Breve (moderate).

From our pharmacist’s overview on the Dalbavancin Hydrochloride page

“Everything on the dalbavancin (Dalvance) interaction list points in one direction. No supplement on file makes this IV skin-infection antibiotic dangerous or weaker; instead, dalbavancin can kill the live organisms in probiotic products, so the supplement is the one that loses.”

About Brewer's Yeast

What is Brewer's Yeast?

Brewer's Yeast
  • Source of B vitamins
  • Diarrhea (certain types)
  • Cold and flu support
  • Digestive health
  • Acne and skin health
  • Blood sugar support

Brewer's yeast is a nutrient-rich fungus that provides B vitamins, protein, and minerals, and a related yeast product (S. boulardii) is used for some types of diarrhea. Most other health claims have limited or weak evidence. It is generally well tolerated as a food or supplement, but talk to your pharmacist or doctor before using it regularly, especially if you have a weakened immune system.

Saccharomyces cerevisiae · Saccharomycetaceae · Whole dried yeast cells (and their fermentation products) · Tablets, capsules, powder, flakes, liquid

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

Brewer's Yeast: dosing

There is no single official or proven dose for brewer's yeast. Products vary widely in their form (tablets, powder, flakes) and in how much yeast they contain.The best approach is to follow the directions on the product label and start with a lower amount to see how your stomach handles it. They can help you decide whether it is appropriate and whether a different, better-studied product (such as a specific probiotic) might be a better fit.

About Dalbavancin Injection

What Is Dalbavancin Injection Used For?

Brand name: Dalvance

Dalvance (dalbavancin) injection is approved to treat acute bacterial skin and skin structure infections (ABSSSI) in adults and children from birth through age 17. These are serious bacterial skin infections that require treatment with an antibacterial given by IV.

It works against specific Gram-positive bacteria, including Staphylococcus aureus (both methicillin-susceptible and methicillin-resistant strains, known as MRSA), several Streptococcus species, and vancomycin-susceptible Enterococcus faecalis. It should only be used when one of these susceptible bacteria is proven or strongly suspected to be causing the infection.

Taking Brewer's Yeast and Dalbavancin Hydrochloride Together: Common Questions

Is it safe to take Brewer's Yeast with Dalbavancin Hydrochloride?
We do not list a known interaction between Brewer's Yeast and Dalbavancin Hydrochloride. 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 Brewer's Yeast and Dalbavancin Hydrochloride have any of the same side effects?
Yes — our sources link each of them separately to 6 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 Brewer's Yeast and Dalbavancin Hydrochloride combination checked?
Interactions in our licensed database are recorded against drug classes. Dalbavancin Hydrochloride is filed under 1 classification, and Brewer's Yeast has documented interactions with 4 drug classes — none of Dalbavancin Hydrochloride'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 Brewer's Yeast interact with any other medications?
Yes. Brewer's Yeast has 136 documented drug interactions in our database — Dalbavancin Hydrochloride 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 Dalbavancin Hydrochloride interact with any supplements?
Yes. Dalbavancin Hydrochloride has documented interactions with 27 supplements in our database — Brewer's Yeast is not one of them. The Dalbavancin Hydrochloride interaction page linked on this page lists every one, ranked by severity.
