Drug & supplement interaction

Black Walnut + Dalbavancin Hydrochloride

Dalbavancin Hydrochloride brand name: Dalvance.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 27, 2026
The bottom line No known interaction

We found no known interaction between Black Walnut 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.

Black Walnut 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 Black Walnut 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 Black Walnut at all — not against Dalbavancin Hydrochloride, 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 Black Walnut 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. 2 of them are worth acting on rather than waiting out — marked below.

  • A severe allergic reaction Worth acting on Additional detail

    Black Walnut

    “Orally, black walnut fruit (nut) is well tolerated. However, the leaf, bark, and hull of black walnut contain high quantities of tannins, which may cause adverse effects when used orally or topically.

    Most Common Adverse Effects:

    Orally: The leaf, bark, and hull can cause gastrointestinal upset.

    Topically: Hull preparations may cause a temporary yellow or brown discoloration at the site of application.”

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 Black Walnut

What is Black Walnut?

  • Intestinal parasites and worms
  • Digestive complaints
  • Antimicrobial and antifungal support
  • Skin and topical washes
  • Laxative or 'cleanse' products

Black walnut is a tree whose green hulls are traditionally used as a natural antiparasitic and digestive remedy, but solid human evidence for these uses is lacking. It contains a compound called juglone that may be irritating, so use it cautiously, avoid long-term use, and check with your pharmacist or doctor first.

Juglans nigra · Juglandaceae · Hulls (the green outer covering of the nut), bark, leaves, and nut · Capsules, tinctures, liquid extracts, powders, and teas

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

Black Walnut: dosing

There is no well-established, standardized dose for black walnut. The amount of active compounds varies a lot between products and forms (capsule, tincture, or tea), which makes consistent dosing difficult.If you choose to use it, follow the directions on the product label and do not exceed them.
