Drug & supplement interaction

Andrographis + 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 Andrographis 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.

Interaction report

Andrographis 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 Andrographis 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.

Andrographis safety at a glance

Andrographis overall Use caution Often well tolerated short-term, but quality of products and long-term safety are not well established.
Pregnancy Possibly Unsafe When used orally. Andrographis is thought to have abortifacient effects; avoid using. Read the full pregnancy detail
Breastfeeding Avoid Not enough safety information, so avoid use while breastfeeding.

Pregnancy & breastfeeding ratings are from Natural Medicines (Therapeutic Research Center) — the full detail is in the Special populations card below. Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Methylene Blue

Interactions in our licensed database are recorded against drug classes, not just single drug names. Methylene Blue is filed under 3 classifications — serotonergic drugs, serotonergic drugs, oral drugs. Andrographis has documented interactions with 6 drug classes — the most serious being anticoagulant/antiplatelet drugs (moderate), antihypertensive drugs (moderate) and immunosuppressants (moderate) — and none of Methylene Blue’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.

Keep it in perspective

Andrographis Does Interact With Other Medications

Andrographis has 408 moderate, 5 minor known drug interactions in our database — Methylene Blue isn’t one of them. If you take anything else, check it against the full list below.

What to actually watch for

No Interaction Found — But Data Suggests Andrographis 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.

Reported for Andrographis but not commonly for Methylene Blue: a severe skin reaction, stomach upset, sweating and an allergic reaction.

Effects for Methylene Blue come from the ADVERSE REACTIONS section of its FDA label; effects for Andrographis come from the Natural Medicines adverse-effect record, quoted above. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

Everything else you take

See Every Supplement That Interacts With Methylene Blue

This page covers Andrographis 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 Andrographis

What is Andrographis?

Andrographis
  • Common cold and flu symptoms
  • Upper respiratory infections
  • Sore throat
  • Fever
  • Immune support
  • Digestive complaints

Andrographis is a bitter Asian herb traditionally used for colds, flu, and infections, and some studies suggest it may ease cold symptoms and shorten how long they last. The evidence is limited and the quality of studies varies, so it should not replace standard care. Talk to your pharmacist or doctor before using it, and avoid it during pregnancy.

Andrographis paniculata · Acanthaceae · Leaves and above-ground (aerial) parts · Capsules, tablets, tinctures, teas, and standardized extracts

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

Andrographis: dosing

There is no single official or standardized dose of Andrographis. Products differ in how they are made and in how much andrographolide they contain, which makes general dosing recommendations difficult.Many cold-related products are standardized to a specific amount of andrographolide and are usually taken for a short period at the start of symptoms.

Taking Andrographis and Methylene Blue Together: Common Questions

Is it safe to take Andrographis with Methylene Blue?
We do not list a known interaction between Andrographis and Methylene Blue. 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 Andrographis and Methylene Blue have any of the same side effects?
Yes — our sources link each of them separately to 4 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 Andrographis and Methylene Blue combination checked?
Interactions in our licensed database are recorded against drug classes. Methylene Blue is filed under 3 classifications, and Andrographis has documented interactions with 6 drug classes — none of Methylene Blue'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 Andrographis interact with any other medications?
Yes. Andrographis has 413 documented drug interactions in our database — Methylene Blue 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 Methylene Blue interact with any supplements?
Yes. Methylene Blue has documented interactions with 38 supplements in our database — Andrographis is not one of them. The Methylene Blue interaction page linked on this page lists every one, ranked by severity.
