Drug & supplement interaction

Mullein + Cedazuridine, Decitabine

Cedazuridine, Decitabine brand name: Inqovi.

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 Mullein and Cedazuridine, Decitabine 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

Mullein and Cedazuridine, Decitabine

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 Cedazuridine, Decitabine 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 Cedazuridine, Decitabine

Interactions in our licensed database are recorded against drug classes, not just single drug names. Cedazuridine, Decitabine is filed under a single classification — oral drugs. Mullein has documented interactions with 1 drug class — the most serious being anticoagulant/antiplatelet drugs (minor) — and none of Cedazuridine, Decitabine’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.

No Interaction Found — But Data Suggests Mullein and Cedazuridine, Decitabine May Share a Side Effect

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.

From our pharmacist’s overview on the Cedazuridine, Decitabine page

“Inqovi pairs decitabine, an oral chemotherapy for certain blood cancers, with cedazuridine, whose whole job is helping the decitabine absorb properly. That is exactly why this list warrants genuine care, because every flagged supplement works the same way, by interfering with absorption in the gut.”

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.
