Drug & supplement interaction

Pleurisy Root + Naloxone

Naloxone brand names: Narcan, Zimhi, Rivive.

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 Pleurisy Root and Naloxone 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.

Pleurisy Root and Naloxone

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 Naloxone 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 Naloxone

Interactions in our licensed database are recorded against drug classes, not just single drug names. Naloxone is filed under a single classification. 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 Naloxone’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 Naloxone 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.

Everything else you take

See Every Supplement That Interacts With Naloxone

This page covers Pleurisy Root only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Naloxone page lists 3 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: 1,4-butanediol (moderate), Gamma Butyrolactone (gbl) (moderate) and Gamma-hydroxybutyrate (ghb) (moderate).

By severity: 3 moderate.

From our pharmacist’s overview on the Naloxone page

“The list of supplements that interact with naloxone, the emergency spray or injection (Narcan, Zimhi, Rivive) that reverses opioid overdoses, is short and unusual. All three entries are forms of the same substance: gamma-hydroxybutyrate (GHB) and two chemicals the body converts into it, GBL and 1,4-butanediol.”

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 Naloxone Injection

What Is Naloxone Injection Used For?

Brand names: Narcan, Zimhi, Rivive

Naloxone Hydrochloride injection is used for the emergency treatment of known or suspected opioid overdose — reversing dangerous slowing of breathing and loss of consciousness caused by opioids. It is also approved for use in pediatric patients of all ages.

Naloxone Hydrochloride injection is additionally indicated specifically for military personnel and chemical incident responders: for emergency treatment of patients 12 and older where high-potency opioids such as fentanyl analogues have been used as a chemical weapon, and for temporary protection against breathing and nervous system depression when entering an area contaminated with such opioids. Zimhi (naloxone HCl) is a pre-filled, single-dose injectable product approved for intramuscular or subcutaneous use in known or suspected opioid overdose.

Taking Pleurisy Root and Naloxone Together: Common Questions

Is it safe to take Pleurisy Root with Naloxone?
We do not list a known interaction between Pleurisy Root and Naloxone. 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 Naloxone have any of the same side effects?
Yes — our sources link each of them separately to 3 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 Naloxone combination checked?
Interactions in our licensed database are recorded against drug classes. Naloxone is filed under 1 classification, and Pleurisy Root has documented interactions with 3 drug classes — none of Naloxone'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 — Naloxone 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 Naloxone interact with any supplements?
Yes. Naloxone has documented interactions with 3 supplements in our database — Pleurisy Root is not one of them. The Naloxone interaction page linked on this page lists every one, ranked by severity.
