Drug & supplement interaction

Andarine + Etoposide

Etoposide brand names: VePesid, VP16, Etopophos.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 20, 2026
The bottom line No known interaction

We found no known interaction between Andarine and Etoposide 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

Andarine and Etoposide

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 Etoposide and Andarine 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 Etoposide

Interactions in our licensed database are recorded against drug classes, not just single drug names. Etoposide is filed under 7 classifications — including topoisomerase ii inhibitors, antineoplastics, organic anion-transporting polypeptide substrates (oatp). Andarine has documented interactions with 1 drug class — the most serious being androgens (moderate) — and none of Etoposide’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.

What to actually watch for

No Interaction Found — But Data Suggests Andarine and Etoposide 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. One of them is worth acting on rather than waiting out — marked below.

    Andarine

    “Orally, selective androgen receptor modulators, such as andarine, could potentially increase the risk of myocardial infarction, stroke, and liver toxicity. However, no thorough safety evaluations of andarine have been conducted.”

    Etoposide

    Listed in the ADVERSE REACTIONS section of the FDA label for Etoposide. Read the label on DailyMed ›

Reported for Andarine but not commonly for Etoposide: a heart attack.

Effects for Etoposide come from the ADVERSE REACTIONS section of its FDA label; effects for Andarine come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 74,570 voluntary FDA FAERS reports for Etoposide that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

Everything else you take

See Every Supplement That Interacts With Etoposide

This page covers Andarine only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Etoposide page lists 152 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Apple (major), Grapefruit (major), St. John's Wort (major) and Sweet Orange (major).

By severity: 5 major · 107 moderate · 40 minor.

From our pharmacist’s overview on the Etoposide page

“Chemotherapy is unforgiving of level swings, and swings are exactly what most of this list can cause for etoposide (VePesid, Etopophos). Of the 152 supplements and herbs on file, 121 can change how your liver clears etoposide through the CYP3A4 enzyme, meaning too little drug and an undertreated cancer, or too much and harsher toxicity.”

About Andarine

What is Andarine?

Andarine
  • Muscle building
  • Strength gains
  • Fat loss / body recomposition
  • Athletic performance enhancement
  • Bone density support

Andarine (S-4) is a synthetic selective androgen receptor modulator (SARM) that is not approved by the FDA for human use and is banned in sports. It is not a legal dietary supplement ingredient, its long-term safety in people is unknown, and reported side effects include vision changes and possible liver and hormone problems. Because of these risks and its illegal status, we do not recommend using it.

Not applicable (synthetic chemical compound) · Capsules, tablets, liquid solutions (sold as research chemicals)

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

Andarine: dosing

There is no established or approved dose for Andarine because it is not a recognized medicine or legal supplement. We cannot recommend a safe dose, and doses circulated online are not backed by proper human research.Given that it is unapproved, potentially unsafe, and illegal to sell as a supplement, the safest choice is not to use it at all.

About Etoposide

What Is Etoposide Used For?

Brand names: VePesid, VP16, Etopophos

Etoposide injection (available as Avopef, Etopophos, Toposar, and Etoposide) is used to treat refractory testicular tumors — cancers that have already been treated with surgery, radiation, and other chemotherapy — always in combination with other cancer drugs. It is also used for small cell lung cancer (SCLC) as a first-line treatment, given together with other chemotherapy and, in the case of Avopef, with immunotherapy as well.

Etoposide capsules (VePesid and Etoposide capsules) are approved for small cell lung cancer as first-line treatment in combination with other chemotherapy agents. Capsule forms are not approved for testicular cancer, as the label notes that adequate data on their use in that setting are not available.

Most-Reported Side Effects for Etoposide

From FAERS, the FDA’s public side-effect reporting system (74,570 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Febrile neutropenia 7,773 reports
Neutropenia 5,108 reports
Disease progression 4,642 reports

Taking Andarine and Etoposide Together: Common Questions

Is it safe to take Andarine with Etoposide?
We do not list a known interaction between Andarine and Etoposide. 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 Andarine and Etoposide 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 Andarine and Etoposide combination checked?
Interactions in our licensed database are recorded against drug classes. Etoposide is filed under 7 classifications, and Andarine has documented interactions with 1 drug class — none of Etoposide'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 Andarine interact with any other medications?
Yes. Andarine has 9 documented drug interactions in our database — Etoposide 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 Etoposide interact with any supplements?
Yes. Etoposide has documented interactions with 152 supplements in our database — Andarine is not one of them. The Etoposide interaction page linked on this page lists every one, ranked by severity.
