Drug & supplement interaction

Pleurisy Root + Dantrolene

Dantrolene brand names: Dantrium, Dantrium Intravenous.

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 Pleurisy Root and Dantrolene 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

Pleurisy Root and Dantrolene

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 Dantrolene and Pleurisy Root 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.

How we checked

Why No Interaction Is Listed for Dantrolene

Interactions in our licensed database are recorded against drug classes, not just single drug names. Dantrolene is filed under 4 classifications — including skeletal muscle relaxants, photosensitizing drugs, hepatotoxic drugs. Pleurisy Root has documented interactions with 3 drug classes — the most serious being digoxin (lanoxin) (major), diuretic drugs (moderate) and estrogens (moderate) — and none of Dantrolene’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

No Interaction Found — But Data Suggests Pleurisy Root and Dantrolene 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.

From our pharmacist’s overview on the Dantrolene page

“People take dantrolene (Dantrium) for muscle spasticity from multiple sclerosis or spinal cord injury, and the drug already carries a boxed warning for liver injury. That is why its supplement interactions deserve genuine respect.”

About Pleurisy Root

What is Pleurisy Root?

  • Respiratory congestion
  • Pleurisy and chest discomfort
  • Coughs and bronchitis
  • Promoting sweating during fevers
  • Loosening mucus

Pleurisy root is the dried root of Asclepias tuberosa (butterfly weed), a plant used in traditional North American and herbal medicine mainly for respiratory complaints. There is very little modern scientific evidence that it works for any condition, and it contains compounds that can be toxic, so caution is strongly advised. Pregnant and breastfeeding people should avoid it, and anyone considering it should check with a pharmacist or doctor first.

Asclepias tuberosa · Apocynaceae · Dried root · Tea, tincture, capsules, dried root

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

Pleurisy Root: dosing

There is no well-established or standardized dose for pleurisy root, and the strength of products can vary widely. Because of its potential toxicity, more is not better and self-dosing can be risky.If you choose to use a commercial product, follow the directions on the label and do not exceed them.

About Dantrolene

What Is Dantrolene Used For?

Brand names: Dantrium, Dantrium Intravenous

Dantrolene sodium capsules (Dantrium, Dantrolene Sodium) are used by mouth to control spasticity — painful or disabling muscle stiffness and spasms — caused by upper motor neuron disorders such as spinal cord injury, stroke, cerebral palsy, or multiple sclerosis. They are not used for muscle spasm from arthritis or other rheumatic conditions. Oral capsules are also used before and after surgery to prevent or reduce the risk of malignant hyperthermia in patients known to be susceptible.

For an active malignant hyperthermia crisis — a sudden, dangerous overheating of the muscles triggered by certain anesthetics — the intravenous (IV) forms are given in the hospital. Dantrium Intravenous, Revonto, Ryanodex, and Dantrolene injection are all indicated to treat a malignant hyperthermia crisis and may also be given before surgery to help prevent one in high-risk patients.

Taking Pleurisy Root and Dantrolene Together: Common Questions

Is it safe to take Pleurisy Root with Dantrolene?
We do not list a known interaction between Pleurisy Root and Dantrolene. 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 Pleurisy Root and Dantrolene have any of the same side effects?
Yes — our sources link each of them separately to 6 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 Pleurisy Root and Dantrolene combination checked?
Interactions in our licensed database are recorded against drug classes. Dantrolene is filed under 4 classifications, and Pleurisy Root has documented interactions with 3 drug classes — none of Dantrolene'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 Pleurisy Root interact with any other medications?
Yes. Pleurisy Root has 117 documented drug interactions in our database — Dantrolene 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 Dantrolene interact with any supplements?
Yes. Dantrolene has documented interactions with 77 supplements in our database — Pleurisy Root is not one of them. The Dantrolene interaction page linked on this page lists every one, ranked by severity.
