Arimistane + Abiraterone Acetate
Abiraterone Acetate brand names: Zytiga, Yonsa.
We found no known interaction between Arimistane and Abiraterone Acetate 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.
Arimistane and Abiraterone Acetate
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 Abiraterone Acetate and Arimistane 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.
Arimistane safety at a glance
Pregnancy & breastfeeding ratings are from Natural Medicines (Therapeutic Research Center) — the full detail is in the Special populations card below. Safety guidance is general; always confirm with your pharmacist or doctor for your situation.
Why No Interaction Is Listed for Abiraterone Acetate
Interactions in our licensed database are recorded against drug classes, not just single drug names. Abiraterone Acetate is filed under 5 classifications — including cytochrome p450 2d6 (cyp2d6) inhibitors, hepatotoxic drugs, cytochrome p450 3a4 (cyp3a4) substrates. Arimistane has documented interactions with 1 drug class — the most serious being aromatase inhibitors (moderate) — and none of Abiraterone Acetate’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.
Arimistane Does Interact With Other Medications
Arimistane has 4 moderate known drug interactions in our database — Abiraterone Acetate isn’t one of them. If you take anything else, check it against the full list below.

About Arimistane
What is Arimistane?
- Lowering estrogen levels
- Post-cycle therapy after steroid or prohormone use
- Reducing gynecomastia ('gyno')
- Boosting testosterone
- Bodybuilding and physique support
Arimistane (sometimes sold as Estrovade) is a synthetic aromatase inhibitor marketed as a dietary supplement to lower estrogen and raise testosterone, often during or after steroid or prohormone cycles. It is not a true dietary ingredient, has very little human safety data, and U.S. regulators have warned against products containing aromatase inhibitors. Talk to a pharmacist or doctor before using it.
Not applicable (synthetic compound) · Capsules, tablets, powders
An interaction check asks whether these two react with each other — it does not ask whether Arimistane is a good idea for someone in your situation. Here is what our Arimistane record says about it on its own.
Arimistane: dosing
There is no officially established or proven safe dose for Arimistane. It has not gone through the testing that approved medicines undergo, so reliable dosing guidance does not exist.Product labels vary widely, and the actual amount in a given product may not match what is claimed. Honestly, for most people the safest choice is to avoid it.

About Abiraterone
What Is Abiraterone Used For?
Brand names: Zytiga, Yonsa
Abiraterone acetate tablets are used to treat two types of advanced prostate cancer: metastatic castration-resistant prostate cancer (CRPC — cancer that has spread and keeps growing despite low testosterone levels) and metastatic high-risk castration-sensitive prostate cancer (CSPC — cancer that has spread but still responds to hormone-lowering treatment). It is always taken together with a corticosteroid — most products pair with prednisone, while Yonsa is specifically indicated with methylprednisolone.
All products — including Abiraterone, Abiraterone Acetate, Abirtega, Yonsa, and Zytiga — are taken by mouth as a tablet. Yonsa is approved only for metastatic CRPC, while the other products (Abiraterone, Abiraterone Acetate, Abirtega, and Zytiga) are approved for both metastatic CRPC and metastatic high-risk CSPC.
