Griffonia Simplicifolia + Dalbavancin Hydrochloride

Dalbavancin Hydrochloride brand name: Dalvance.

No Known Interaction

Medically reviewed by Dr. Brian Staiger, PharmD, BCPS · Updated July 2026 · Pair last verified Sep 13, 2026

The bottom line No known interaction

We found no known interaction between Griffonia Simplicifolia 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

Griffonia Simplicifolia 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 Griffonia Simplicifolia 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.

Griffonia Simplicifolia safety at a glance

Griffonia Simplici... overall Use caution May be tolerated by some adults, but quality evidence is limited and side effects can occur.

Pregnancy Avoid Not enough safety data, so it is best avoided during pregnancy.

Breastfeeding Avoid Not enough safety data, so it is best avoided while breastfeeding.

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. Griffonia Simplicifolia has documented interactions with 8 drug classes — the most serious being antidepressant drugs (moderate), carbidopa (lodosyn) (moderate) and cns depressants (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 Griffonia Simplicifolia 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. One of them is worth acting on rather than waiting out — marked below.

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 Griffonia Simplicifolia

What is Griffonia Simplicifolia?

Low mood
Sleep problems
Anxiety
Appetite control
Headaches

Griffonia simplicifolia is a West African shrub whose seeds are a natural source of 5-HTP, a building block of the brain chemical serotonin. Some people use it for mood, sleep, and appetite, but high-quality human evidence is limited, and it should not replace prescribed treatment. Talk with your pharmacist or doctor before using it, especially if you take medicines that affect serotonin.

Griffonia simplicifolia · Fabaceae · Seeds · Capsules, tablets, powder, standardized 5-HTP extracts

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

Griffonia Simplicifolia: dosing

There is no official, well-established dose for Griffonia simplicifolia. Products are usually standardized to a certain amount of 5-HTP, and the strength can differ a lot from one brand to another.The safest approach is to follow the directions on the product label and not exceed the recommended amount.

Taking Griffonia Simplicifolia and Dalbavancin Hydrochloride Together: Common Questions

Is it safe to take Griffonia Simplicifolia with Dalbavancin Hydrochloride?

We do not list a known interaction between Griffonia Simplicifolia 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 Griffonia Simplicifolia and Dalbavancin Hydrochloride have any of the same side effects?

Yes — our sources link each of them separately to 7 of the same effects. That is not an interaction: neither changes how your body handles the other.

How was the Griffonia Simplicifolia and Dalbavancin Hydrochloride combination checked?

Interactions in our licensed database are recorded against drug classes. Dalbavancin Hydrochloride is filed under 1 classification, and Griffonia Simplicifolia has documented interactions with 8 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 Griffonia Simplicifolia interact with any other medications?

Yes. Griffonia Simplicifolia has 317 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.
