The bottom line No known interaction

We found no known interaction between Feng Shui 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.

Feng Shui 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 Feng Shui 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 Feng Shui at all — not against Propoxyphene, 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

What Propoxyphene’s Own FDA Label Lists

This is not an interaction — none of it involves Feng Shui. These are the most notable effects listed in the ADVERSE REACTIONS section of Propoxyphene’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both. 10 of them are worth acting on rather than waiting out — marked below.

  • Trouble swallowing Worth acting on
  • High blood sugar Worth acting on
  • Fainting Worth acting on
  • Confusion Worth acting on
  • A severe skin reaction Worth acting on
  • Seizures Worth acting on
  • Low mood Worth acting on
  • A low platelet count Worth acting on
  • Kidney problems Worth acting on
  • Shortness of breath Worth acting on

Showing the 10 most notable of 36 label-listed effects — ranked by how unusual each one is across medicines generally, with serious effects weighted up.

From the ADVERSE REACTIONS section of the FDA label for Propoxyphene. Read the label on DailyMed › Feng Shui’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Feng Shui side to compare — that is a limit of the record, not a statement that Feng Shui has no side effects.

Everything else you take

See Every Supplement That Interacts With Propoxyphene

This page covers Feng Shui 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.”

Where does our data come from?
  • Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. Feng Shui is not yet covered by that licensed database, so its write-up cites publicly available medical sources directly (see the references below).
  • Citation library: 103,510 references behind our interaction content, 65,311 of them resolved to verified PubMed/DOI sources. See every Feng Shui reference on this page ↓
  • Freshness: we automatically re-check this combination every week — this pair was last verified September 13, 2026. The Feng Shui and Propoxyphene records this page draws on were last updated June 20, 2026.
  • What “no known interaction” means: no documented interaction in the sources above — not a guarantee of safety. Supplements are studied far less than prescription drugs, so we say exactly what the evidence supports, and nothing more.

About Feng Shui

What is Feng Shui?

"Feng Shui" is not a dietary supplement or medicinal herb. It is a traditional Chinese practice of arranging living and working spaces to promote harmony and balance, so there is nothing to take or dose. If you saw "Feng Shui" listed as a supplement product, the name is being used as branding, and you should check the actual ingredients on the label and ask a pharmacist before using it.

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

Feng Shui: dosing

There is no dose for Feng Shui because it is not a supplement or herb.

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.
