The bottom line No known interaction

Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first.

Red Sandalwood and Oxymorphone

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 Oxymorphone and Red Sandalwood 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 Oxymorphone

Interactions in our licensed database are recorded against drug classes, not just single drug names. Oxymorphone is filed under 4 classifications — including narcotic drugs, cns depressants, seizure threshold lowering drugs. Red Sandalwood has documented interactions with 2 drug classes — the most serious being antidiabetes drugs (moderate) and lithium (moderate) — and none of Oxymorphone’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.

About Red Sandalwood

What is Red Sandalwood?

  • Skin care and complexion
  • Acne and skin blemishes
  • Inflammation and minor wounds
  • Digestive complaints (traditional use)
  • Coloring and flavoring agent

Red Sandalwood (Pterocarpus santalinus) is a hardwood used in traditional medicine and in skin and cosmetic preparations, valued for its red pigment and astringent properties. Solid human evidence for its health benefits is very limited, and most claims come from traditional use or laboratory studies. If you want to try it, talk with your pharmacist or doctor first, especially before taking it internally.

Pterocarpus santalinus · Fabaceae · Heartwood (and wood powder/extract) · Wood powder, paste, decoctions, extracts, and as an ingredient in skin and cosmetic preparations

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

Red Sandalwood: dosing

There is no well-established standard dose for Red Sandalwood. Traditional preparations vary widely, and modern clinical dosing has not been defined.If you use a commercial product, follow the directions on the label and do not exceed the recommended amount.

About Oxymorphone

What Is Oxymorphone Used For?

Brand names: Numorphan, Opana, Opana ER, Opana Injection

Oxymorphone Hydrochloride Tablets (immediate-release) are used to treat acute pain severe enough to require an opioid when other pain treatments are not enough. Oxymorphone Hydrochloride Extended-Release Tablets are used to manage severe, persistent pain that needs to be treated with a daily opioid over an extended period and when other options are inadequate.

Both forms are reserved for situations where non-opioid medicines or other approaches have not worked well enough. Oxymorphone Hydrochloride Extended-Release Tablets are not meant to be taken on an as-needed basis — they are for ongoing, around-the-clock pain management only.
