Propoxyphene brand names: Darvon, Prophene-65, Margesic, Davon.

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 Hydrangea and Propoxyphene 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

Hydrangea and Propoxyphene

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 Propoxyphene and Hydrangea 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.

Hydrangea safety at a glance

Hydrangea overall Use caution Human safety data are limited, and large or prolonged doses may cause unwanted effects.
Pregnancy Avoid Not enough safety information exists, so it is best avoided during pregnancy.
Breastfeeding Avoid There is no reliable safety data, so avoid use 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 Propoxyphene

Interactions in our licensed database are recorded against drug classes, not just single drug names. Propoxyphene is filed under 7 classifications — including narcotic drugs, cytochrome p450 2d6 (cyp2d6) inhibitors, cytochrome p450 2d6 (cyp2d6) substrates. Hydrangea has documented interactions with 1 drug class — the most serious being lithium (moderate) — and none of Propoxyphene’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 Hydrangea and Propoxyphene 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.

Everything else you take

See Every Supplement That Interacts With Propoxyphene

This page covers Hydrangea only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Propoxyphene page lists 172 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: 1,4-butanediol (major), Activated Charcoal (major), Beer (major), Gamma-hydroxybutyrate (ghb) (major) and Kava (major).

By severity: 8 major · 141 moderate · 23 minor.

From our pharmacist’s overview on the Propoxyphene page

“Propoxyphene (Darvon) is an opioid painkiller, and the biggest hazard among the 172 supplement interactions on file is anything else that slows the brain and breathing. Seventy-eight of these ingredients pile on that sedation, alcohol and kava among the worst rated, and with an opioid the combination can push breathing dangerously low.”

About Hydrangea

What is Hydrangea?

  • Kidney and bladder stones
  • Urinary tract complaints
  • Enlarged prostate symptoms
  • Mild diuretic (increasing urine)
  • Bladder infections (traditional use)

Hydrangea root has a long history in folk medicine, mainly for urinary and kidney stone complaints, but there is very little modern human research to confirm it works for any condition. Because safety data are limited and large amounts may be harmful, it is best to talk with a pharmacist or doctor before using it.

Hydrangea arborescens · Hydrangeaceae · Root and rhizome (underground stem) · Dried root, tincture, liquid extract, capsules, tea

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

Hydrangea: dosing

There is no well-established or standardized dose for hydrangea, because it has not been studied carefully in people. Traditional preparations used the dried root as a tea or tincture, but reliable, specific amounts are not available.If you choose to use a product, follow the directions on the label and do not exceed them.

About Acetaminophen, Butalbital, and Caffeine

What Is Acetaminophen, Butalbital, and Caffeine Used For?

Brand names: Darvon, Prophene-65, Margesic, Davon

This three-ingredient combination — butalbital, acetaminophen, and caffeine — is used to relieve the symptoms of tension headache (also called muscle contraction headache). All supported products, including tablets, capsules, and oral solution, share this same approved use.

It is worth knowing that evidence for using this combination to treat repeated, frequent tension headaches over time is limited. Because butalbital can be habit-forming, extended or repeated use is not recommended.

Taking Hydrangea and Propoxyphene Together: Common Questions

Is it safe to take Hydrangea with Propoxyphene?
We do not list a known interaction between Hydrangea and Propoxyphene. 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 Hydrangea and Propoxyphene have any of the same side effects?
Yes — our sources link each of them separately to one 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 Hydrangea and Propoxyphene combination checked?
Interactions in our licensed database are recorded against drug classes. Propoxyphene is filed under 7 classifications, and Hydrangea has documented interactions with 1 drug class — none of Propoxyphene'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 Hydrangea interact with any other medications?
Yes. Hydrangea has 1 documented drug interaction in our database — Propoxyphene 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 Propoxyphene interact with any supplements?
Yes. Propoxyphene has documented interactions with 172 supplements in our database — Hydrangea is not one of them. The Propoxyphene interaction page linked on this page lists every one, ranked by severity.
