The bottom line No known interaction

We found no known interaction between Arimistane and Esomeprazole 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 Esomeprazole states a food rule worth keeping to.

Arimistane and Esomeprazole

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 Esomeprazole 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 Esomeprazole

Interactions in our licensed database are recorded against drug classes, not just single drug names. Esomeprazole is filed under 6 classifications — including proton pump inhibitors (ppis), cytochrome p450 2c19 (cyp2c19) inhibitors, cytochrome p450 1a2 (cyp1a2) inducers. Arimistane has documented interactions with 1 drug class — the most serious being aromatase inhibitors (moderate) — and none of Esomeprazole’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 Esomeprazole’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 Esomeprazole’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. 10 of them are worth acting on rather than waiting out — marked below.

  • Kidney problems Worth acting on mentioned in 30.8% of FDA reports for Esomeprazole
  • Loss of vision Worth acting on
  • Low magnesium Worth acting on
  • Bone thinning Worth acting on
  • Pain or burning when passing urine Worth acting on
  • Muscle weakness Worth acting on
  • Trouble swallowing Worth acting on
  • Bleeding in the gut Worth acting on
  • Low sodium Worth acting on
  • Low potassium Worth acting on

Showing the 10 most notable of 73 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 Esomeprazole. Read the label on DailyMed › Where a percentage is shown, it is the share of 235,235 voluntary FDA FAERS reports for Esomeprazole 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.

How to take them

Some Esomeprazole Products Have a Food Rule — Arimistane Should Not Break It

At least one FDA label for a product containing Esomeprazole says to take it on an empty stomach. Most supplements — Arimistane included — are taken with a meal, so the easy mistake is swallowing both together at breakfast. Where that rule applies, keep Esomeprazole on its own and move Arimistane to a meal later in the day.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Esomeprazole 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.

Table 2: Recommended Dosage of Esomeprazole Magnesium Delayed-Release Capsules in Pediatric Patients by Indication Indication Patient Age Recommended Dosage Duration Healing of EE 12 years to 17 years Esomeprazole magnesium delayed-release capsules: 20 mg or 40 mg once daily 4 to 8 Weeks Treatment of Symptomatic GERD 12 years to 17 years Esomeprazole magnesium delayed-release capsules: 20 mg once

From the Dosage and Administration section of the FDA label we read for Esomeprazole — 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.

From our pharmacist’s overview on the Esomeprazole page

“St. John's wort can lower the amount of esomeprazole (Nexium) in your blood by speeding up how the liver clears it, which can leave heartburn or ulcer treatment falling short.”

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 Esomeprazole

What Is Esomeprazole Used For?

Brand name: Nexium

Esomeprazole treats problems caused by excess stomach acid. It's used to heal erosive esophagitis (damage to the esophagus from acid), control GERD (gastroesophageal reflux disease) symptoms like heartburn, and protect the stomach lining in people at risk for ulcers caused by NSAIDs (anti-inflammatory pain relievers like ibuprofen).

It's also used as part of a three-drug combination to wipe out H. pylori — a stomach bacteria linked to ulcers — and for people with rare conditions that cause the stomach to overproduce acid, such as Zollinger-Ellison syndrome.

Most-Reported Side Effects for Esomeprazole

From FAERS, the FDA’s public side-effect reporting system (235,235 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Chronic kidney disease 35,589 reports
Acute kidney injury 20,510 reports
Renal failure 16,295 reports

Taking Arimistane and Esomeprazole Together: Common Questions

Is it safe to take Arimistane with Esomeprazole?
We do not list a known interaction between Arimistane and Esomeprazole. 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.
Should I take Arimistane and Esomeprazole at the same time of day?
At least one FDA label for a product containing Esomeprazole says to take it on an empty stomach, and supplements are usually taken with a meal — so taking them together at breakfast is the easy mistake. Where that applies, keep Esomeprazole on its own and move Arimistane to a meal later in the day. Food instructions belong to the product rather than the ingredient, so check the directions on your own box. This is about absorption, not an interaction.
How was the Arimistane and Esomeprazole combination checked?
Interactions in our licensed database are recorded against drug classes. Esomeprazole is filed under 6 classifications, and Arimistane has documented interactions with 1 drug class — none of Esomeprazole'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 Arimistane interact with any other medications?
Yes. Arimistane has 4 documented drug interactions in our database — Esomeprazole 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 Esomeprazole interact with any supplements?
Yes. Esomeprazole has documented interactions with 154 supplements in our database — Arimistane is not one of them. The Esomeprazole interaction page linked on this page lists every one, ranked by severity.
