Drug & supplement interaction

Ostarine + Buspirone

Buspirone brand name: BuSpar.

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 Ostarine and Buspirone 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

Ostarine and Buspirone

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 Buspirone and Ostarine 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.

Ostarine overall Avoid Ostarine is an unapproved investigational drug with documented safety risks and no FDA approval.
Pregnancy Avoid It affects hormone pathways and must be avoided during pregnancy.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Buspirone

Interactions in our licensed database are recorded against drug classes, not just single drug names. Buspirone is filed under 5 classifications — including serotonergic drugs, serotonergic drugs, cytochrome p450 3a4 (cyp3a4) substrates. Ostarine has documented interactions with 6 drug classes — the most serious being cytochrome p450 3a4 (cyp3a4) inducers (moderate), hepatotoxic drugs (moderate) and probenecid (benemid) (moderate) — and none of Buspirone’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 Ostarine and Buspirone 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. 3 of them are worth acting on rather than waiting out — marked below.

    Ostarine

    “Orally, in a 12-week study of healthy elderly patients taking ostarine daily, high-density lipoprotein (HDL) cholesterol levels decreased by 9 mg/dL and 15 mg/dL with ostarine 1 mg and 3 mg, respectively, when compared with placebo. Theoretically, reductions in HDL reported with ostarine could potentially increase the risk for adverse cardiovascular effects. In fact, the U.S.”

About Ostarine

What is Ostarine?

  • Muscle building
  • Athletic performance
  • Fat loss / body recomposition
  • Bodybuilding cycles

Ostarine (also called MK-2866 or enobosarm) is an experimental, unapproved drug known as a SARM (selective androgen receptor modulator), not a true dietary supplement. It is not approved by the FDA, is banned in sports, and has been linked to liver injury and other serious harms, so it is not recommended for general use.

Synthetic compound (not from a plant) · Capsules, tablets, liquids, powders sold as research chemicals or 'sports supplements'

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

Ostarine: dosing

There is no established safe or approved dose of Ostarine, because it is not an approved medicine or a legitimate dietary supplement. Doses used in research studies were given under medical supervision and do not apply to over-the-counter use.We do not recommend using Ostarine. Products sold online may not contain the dose listed on the label and may include other hidden substances.

About Buspirone

What Is Buspirone Used For?

Brand name: BuSpar

Buspirone tablets and capsules are used to manage anxiety disorders or to relieve anxiety symptoms in the short term. Its effectiveness has been shown in clinical trials focused on Generalized Anxiety Disorder (GAD) — a condition marked by persistent, hard-to-control worry along with physical symptoms like muscle tension, restlessness, difficulty concentrating, and sleep problems.

Buspirone has also been shown to relieve anxiety in people who have mild depressive symptoms alongside their anxiety. Everyday stress and tension, on their own, generally do not require treatment with a medicine like buspirone.

Taking Ostarine and Buspirone Together: Common Questions

Is it safe to take Ostarine with Buspirone?
We do not list a known interaction between Ostarine and Buspirone. 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 Ostarine and Buspirone have any of the same side effects?
Yes — our sources link each of them separately to 10 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 Ostarine and Buspirone combination checked?
Interactions in our licensed database are recorded against drug classes. Buspirone is filed under 5 classifications, and Ostarine has documented interactions with 6 drug classes — none of Buspirone'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 Ostarine interact with any other medications?
Yes. Ostarine has 611 documented drug interactions in our database — Buspirone 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 Buspirone interact with any supplements?
Yes. Buspirone has documented interactions with 155 supplements in our database — Ostarine is not one of them. The Buspirone interaction page linked on this page lists every one, ranked by severity.
