The bottom line No known interaction

We found no known interaction between Mullein and Esketamine 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.

Mullein and Esketamine

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 Esketamine and Mullein 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.

Mullein safety at a glance

Mullein overall Use caution Generally well tolerated for short-term use, but human safety data are limited.
Pregnancy Avoid Not enough safety information, so it is best avoided during pregnancy.
Breastfeeding Avoid There is not enough data to consider it safe 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 Esketamine

Interactions in our licensed database are recorded against drug classes, not just single drug names. Esketamine is filed under 2 classifications — tricyclic antidepressants (tcas), antidepressant drugs. Mullein has documented interactions with 1 drug class — the most serious being anticoagulant/antiplatelet drugs (minor) — and none of Esketamine’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

What Mullein Itself Has Been Linked To

This is not an interaction — nothing below involves Esketamine. It is the side-effect record for Mullein on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Mullein, this list is the first place to look.

  • A skin rash Additional detail

    “Two case reports have described dermatitis, with positive patch tests, after topical exposure to the whole plant, or by occupational inhalation of plant dust. In the case of topical exposure, the patient also had positive patch tests to other plants.”

Everything above comes from the Natural Medicines adverse-effect record for Mullein — expand a row for the licensed statement it rests on. We read the ADVERSE REACTIONS section of Esketamine’s FDA label too, and the two lists don’t meaningfully overlap — which is why no Esketamine column appears here.

The most serious there right now: Scopolia (major), Cowhage (moderate), Dhea (moderate), Griffonia Simplicifolia (moderate) and Indian Snakeroot (moderate).

By severity: 1 major · 6 moderate · 4 minor.

From our pharmacist’s overview on the Esketamine page

“Esketamine (Spravato) is the nasal spray for depression that hasn't responded to standard treatment, and its supplement list deserves genuine respect. Scopolia carries the only major rating and is the entry to understand before any other; pairing it with the medication can raise the risk of anticholinergic effects, meaning dry mouth, b…”

About Mullein

What is Mullein?

Mullein
  • Cough and chest congestion
  • Sore throat
  • Bronchitis and respiratory irritation
  • Earache (traditional ear oil)
  • Mild inflammation

Mullein is a traditional herbal remedy most often used as a tea or syrup to soothe coughs, sore throats, and respiratory irritation. High-quality human studies are lacking, so its benefits are not well proven, but it is generally considered low-risk for short-term use in healthy adults. Talk to your pharmacist or doctor before using it, especially if you are pregnant, breastfeeding, or have a medical condition.

Verbascum thapsus · Scrophulariaceae · Leaves and flowers (sometimes roots) · Tea (infusion), tincture, capsules, syrups, lozenges, and ear oil drops

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

Mullein: dosing

There is no official or standardized dose for mullein. The amount used varies widely between products and traditional recipes, such as teas, tinctures, capsules, and syrups.The safest approach is to follow the directions on the product label and not exceed the recommended amount. A well-made tea is typically prepared by steeping the dried leaves or flowers in hot water and straining well to remove the irritating plant hairs.

About Esketamine Nasal Spray

What Is Esketamine Nasal Spray Used For?

Brand name: Spravato

Spravato nasal spray is approved for two uses in adults. First, it treats treatment-resistant depression (TRD) — depression that has not responded to other antidepressants — either on its own or alongside an oral antidepressant. Second, it treats depressive symptoms in adults with major depressive disorder (MDD) who have acute suicidal ideation or behavior, always used together with an oral antidepressant in this case.

Important limits: Spravato has not been shown to prevent suicide or reduce suicidal thoughts or behavior on its own. It is not a replacement for hospitalization if that is clinically needed, and it is not approved as an anesthetic.

Most-Reported Side Effects for Esketamine

From FAERS, the FDA’s public side-effect reporting system (17,728 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Dissociation 3,733 reports
Sedation 2,706 reports
Suicidal ideation 1,351 reports
