Drug & supplement interaction

Herb Paris + Naloxone

Naloxone brand names: Narcan, Zimhi, Rivive.

No Known Interaction
The bottom line No known interaction

We found no known interaction between Herb Paris 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.

Herb Paris 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 Herb Paris 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 Herb Paris at all — not against Naloxone, 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 Herb Paris 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.

Everything else you take

See Every Supplement That Interacts With Naloxone

This page covers Herb Paris 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 Herb Paris

What is Herb Paris?

  • Headache and migraine (traditional/homeopathic use)
  • Nerve pain and neuralgia
  • Eye complaints (folk use)
  • Cough and bronchitis (folk use)
  • Inflammation and swelling (traditional use)

Herb Paris (Paris quadrifolia) is a poisonous woodland plant that has been used historically in folk medicine and is sold mainly in highly diluted homeopathic forms. There is no reliable scientific evidence that it treats any health condition, and the raw plant is toxic, so it should not be self-prescribed. Talk to a pharmacist or doctor before using any product containing it.

Paris quadrifolia · Melanthiaceae · Whole herb, rhizome (root), berries, and leaves · Homeopathic preparations (pellets, dilutions); rarely as dried herb

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

Herb Paris: dosing

There is no established safe or effective dose of Herb Paris. The raw plant is toxic, so it should not be self-dosed at all. Homeopathic products come in standardized dilution labels (such as different "C" or "X" potencies), but these reflect homeopathic convention rather than proven dosing.If you choose to use a commercial product, follow the directions on the label exactly 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 Herb Paris and Naloxone Together: Common Questions

Do Herb Paris 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.
