Drug & supplement interaction

Musk + Ospemifene

Ospemifene brand name: Osphena.

No Known Interaction
The bottom line No known interaction

We found no known interaction between Musk and Ospemifene 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 label for Ospemifene states a food rule worth keeping to.

Musk and Ospemifene

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 Ospemifene and Musk 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 Musk at all — not against Ospemifene, 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 Ospemifene’s Own FDA Label Lists

This is not an interaction — none of it involves Musk. These are the most notable effects listed in the ADVERSE REACTIONS section of Ospemifene’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. 6 of them are worth acting on rather than waiting out — marked below.

  • A stroke or mini-stroke Worth acting on
  • Blood clots Worth acting on
  • Bleeding or bruising Worth acting on mentioned in 5.8% of FDA reports for Ospemifene
  • A severe allergic reaction Worth acting on
  • Hives Worth acting on
  • An allergic reaction Worth acting on
  • Flushing mentioned in 14.3% of FDA reports for Ospemifene
  • Muscle pain mentioned in 7.5% of FDA reports for Ospemifene
  • Sweating
  • Itching

Showing the 10 most notable of 12 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 Ospemifene. Read the label on DailyMed › Where a percentage is shown, it is the share of 2,601 voluntary FDA FAERS reports for Ospemifene that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Musk’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Musk side to compare — that is a limit of the record, not a statement that Musk has no side effects.

How to take them

Some Ospemifene Products Have a Food Rule — Musk Should Not Break It

At least one FDA label for a product containing Ospemifene says to take it with food. If you take Musk on an empty stomach out of habit, keep them separate — and take Ospemifene with a meal where the label says to.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Ospemifene products can carry different directions, and extended-release forms often differ from immediate-release ones. The label we read is quoted below — check the directions on your own box or bottle, or ask your pharmacist, for how to take the exact product you were given.

One tablet taken orally once daily with food.

From the Dosage and Administration section of the FDA label we read for Ospemifene — where that label names a specific product, the instruction is that product's. Read the label on DailyMed ›

A food rule is not an interaction — it is about how much of the medicine you absorb. The directions that came with your own product, and your pharmacist, outrank anything on this page.

Everything else you take

See Every Supplement That Interacts With Ospemifene

This page covers Musk only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Ospemifene page lists 155 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Grapefruit (major), St. John's Wort (major), Tiratricol (major) and Acacia Rigidula (moderate).

By severity: 4 major · 112 moderate · 39 minor.

From our pharmacist’s overview on the Ospemifene page

“Women prescribed ospemifene (Osphena) for painful intercourse after menopause are often the same women reaching for St. John's wort for mood or grapefruit juice at breakfast, and both sit among the four major-rated interactions on this page, so the list deserves genuine care.”

Where does our data come from?
  • Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. Musk 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 Musk reference on this page ↓
  • Freshness: we automatically re-check this combination every week — this pair was last verified September 20, 2026. The Musk and Ospemifene records this page draws on were last updated June 22, 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 Musk

What is Musk?

  • Traditional remedy for fainting or loss of consciousness
  • Circulatory and heart-related complaints in folk medicine
  • Pain and swelling (topical traditional use)
  • Perceived aphrodisiac or sexual tonic
  • Fragrance in perfumes and cosmetics

Musk is an animal-derived secretion from the male musk deer that has been used in traditional medicine and perfumery for centuries, but there is very little reliable human evidence to support any health benefit. Because the deer is endangered and trade is heavily restricted, most modern 'musk' products are synthetic or plant-based, and we cannot recommend genuine musk as a supplement. Talk with a pharmacist or doctor before using any product labeled musk.

Glandular secretion from the male musk deer; also synthetic and plant-derived 'musk' substitutes · Traditional medicine pills and powders, perfumes/fragrances, topical preparations

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

Musk: dosing

There is no established or standardized dose for musk as a dietary supplement. Keep in mind that authentic musk is heavily regulated, so a product's true contents may be uncertain.
