Drug & supplement interaction

Sodium Tetrachloroaurate + Methylene Blue

Methylene Blue brand names: Urolene Blue, Provayblue.

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 Sodium Tetrachloroaurate and Methylene Blue 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.

Sodium Tetrachloroaurate and Methylene Blue

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 Methylene Blue and Sodium Tetrachloroaurate 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 Sodium Tetrachloroaurate at all — not against Methylene Blue, 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 Sodium Tetrachloroaurate and Methylene Blue 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.

  • Anemia Worth acting on Additional detail

    Sodium Tetrachloroaurate

    “No adverse effects have been reported; however, a thorough evaluation of safety outcomes has not been conducted. Sodium tetrachloroaurate contains gold and might cause adverse effects similar to other gold salts. Orally, gold salts have been reported to cause gastrointestinal side effects, including diarrhea, loose stools, nausea, vomiting, and abdominal cramps.”

    “Orally, gold salts can cause stomatitis, which may be preceded by a metallic taste. Other adverse events including diarrhea, loose stools, nausea, vomiting, and abdominal cramps may also occur. Ulcerative enterocolitis has also been reported, but this is rare. Sodium tetrachloroaurate is a gold salt and may theoretically cause similar adverse effects.”

Special populations

Sodium Tetrachloroaurate in Pregnancy & Breastfeeding

Pregnancy Possibly Unsafe

When used orally or parenterally. Sodium tetrachloroaurate is a gold salt. Evidence from animal models shows that the administration of other gold salts increases the risk of miscarriage and congenital abnormalities in the offspring. Theoretically, sodium tetrachloroaurate may have similar adverse effects; avoid using.

See Every Supplement That Interacts With Methylene Blue

This page covers Sodium Tetrachloroaurate only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Methylene Blue page lists 38 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Lithium (major), 5-htp (moderate), Acetyl-l-carnitine (moderate) and Ayahuasca (moderate).

By severity: 2 major · 25 moderate · 11 minor.

From our pharmacist’s overview on the Methylene Blue page

“The pairing I would worry about first with methylene blue (Urolene Blue, Provayblue) is anything that raises serotonin, and lithium heads that group with a major rating. Methylene blue inhibits monoamine oxidase A, the enzyme that breaks serotonin down, so combining it with serotonin-boosting supplements can tip someone into serotonin…”

About Sodium Tetrachloroaurate

What is Sodium Tetrachloroaurate?

  • Used in chemistry as a source of gold
  • Gold nanoparticle synthesis (research)
  • Electroplating and gold chemistry
  • Marketed by some sellers as a 'colloidal gold' precursor

Sodium tetrachloroaurate is a gold(III) chemical compound used in laboratories and industry, not a dietary supplement or herb. It is not approved or recommended for human use, and ingesting it can be harmful. Do not take it as a supplement.

Not a plant; this is a chemical gold(III) compound · Laboratory reagent solution; not sold as a dietary supplement

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

Is it safe to take Sodium Tetrachloroaurate with Methylene Blue?
