Drug & supplement interaction

Mugwort + Benzonatate

Benzonatate brand names: Tessalon, Tessalon Perles.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 20, 2026
The bottom line No known interaction

We found no known interaction between Mugwort and Benzonatate 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

Mugwort and Benzonatate

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 Benzonatate and Mugwort 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 Mugwort at all — not against Benzonatate, 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 Mugwort and Benzonatate 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.

  • Wheezing Worth acting on Additional detail

About Mugwort

What is Mugwort?

Mugwort
  • Digestive upset and poor appetite
  • Menstrual discomfort
  • Sleep support and vivid dreaming
  • Used in moxibustion (traditional Chinese medicine)
  • Mild anxiety or relaxation

Mugwort is a traditional herb used for digestion, menstrual issues, and sleep, but there is very little high-quality human research to confirm these uses. It is closely related to ragweed and can trigger allergic reactions, and it should be avoided in pregnancy. Talk with your pharmacist or doctor before using it.

Artemisia vulgaris · Asteraceae · Leaves, flowering tops, and root; sometimes essential oil · Tea, capsules, tincture, dried herb, essential oil, and moxa (used in moxibustion)

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

Mugwort: dosing

There is no well-established, standardized dose for mugwort. The amount in teas, capsules, and tinctures varies a lot between products.If you choose to use mugwort, follow the directions on the product label and do not exceed them. Avoid swallowing the concentrated essential oil.

Taking Mugwort and Benzonatate Together: Common Questions

Do Mugwort and Benzonatate have any of the same side effects?
Yes — our sources link each of them separately to 2 of the same effects. That is not an interaction: neither changes how your body handles the other.
