The bottom line No known interaction

We found no known interaction between Arimistane and Apixaban 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 Apixaban

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 Apixaban 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.

How we checked

Why No Interaction Is Listed for Apixaban

Interactions in our licensed database are recorded against drug classes, not just single drug names. Apixaban is filed under 4 classifications — including anticoagulant/antiplatelet drugs, p-glycoprotein substrates, cytochrome p450 3a4 (cyp3a4) substrates. Arimistane has documented interactions with 1 drug class — the most serious being aromatase inhibitors (moderate) — and none of Apixaban’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

What Apixaban’s Own FDA Label Lists

This is not an interaction — none of it involves Arimistane. These are the most notable effects listed in the ADVERSE REACTIONS section of Apixaban’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. 3 of them are worth acting on rather than waiting out — marked below.

  • Blood clots Worth acting on mentioned in 4.3% of FDA reports for Apixaban
  • An irregular heartbeat Worth acting on mentioned in 6.1% of FDA reports for Apixaban
  • Bleeding or bruising Worth acting on

From the ADVERSE REACTIONS section of the FDA label for Apixaban. Read the label on DailyMed › Where a percentage is shown, it is the share of 66,522 voluntary FDA FAERS reports for Apixaban that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Arimistane’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Arimistane side to compare — that is a limit of the record, not a statement that Arimistane has no side effects.

Arimistane in Pregnancy & Breastfeeding

Pregnancy And Lactation Possibly Unsafe

About Arimistane

What is Arimistane?

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 Apixaban

What Is Apixaban Used For?

Brand name: Eliquis

Apixaban tablets (sold as Eliquis and under the generic name apixaban) are used to reduce the risk of stroke and systemic embolism (clots traveling to other parts of the body) in adults with nonvalvular atrial fibrillation (an irregular heart rhythm not caused by a heart valve problem). They are also used to prevent deep vein thrombosis (DVT — a blood clot in the leg) after hip or knee replacement surgery, and to treat DVT and pulmonary embolism (PE — a blood clot in the lungs), as well as to lower the risk of those clots coming back.

Eliquis is additionally approved to treat venous thromboembolism (VTE — blood clots in the veins) and reduce the risk of recurrent VTE in pediatric patients from birth and older, following at least 5 days of initial anticoagulant treatment.

Most-Reported Side Effects for Apixaban
