Arimistane + Misoprostol
Misoprostol brand name: Cytotec.
We found no known interaction between Arimistane and Misoprostol 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 Misoprostol states a food rule worth keeping to.
Arimistane and Misoprostol
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 Misoprostol 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 Misoprostol
Interactions in our licensed database are recorded against drug classes, not just single drug names. Misoprostol is filed under a single classification — oral drugs. Arimistane has documented interactions with 1 drug class — the most serious being aromatase inhibitors (moderate) — and none of Misoprostol’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 — Misoprostol isn’t one of them. If you take anything else, check it against the full list below.

Some Misoprostol Products Have a Food Rule — Arimistane Should Not Break It
At least one FDA label for a product containing Misoprostol says to take it with food. If you take Arimistane on an empty stomach out of habit, keep them separate — and take Misoprostol with a meal where the label says to.
This may not be true of your version. Food instructions belong to the product, not the ingredient: two Misoprostol 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.
DOSAGE AND ADMINISTRATION The recommended adult oral dose of Cytotec for reducing the risk of NSAID-induced gastric ulcers is 200 mcg four times daily with food.
From the Dosage and Administration section of the FDA label we read for Misoprostol — 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.
See Every Supplement That Interacts With Misoprostol
This page covers Arimistane only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Misoprostol page lists 17 supplements it has a documented interaction with, worst first, each one explained.
The most serious there right now: Activated Charcoal (major), Coffee Charcoal (moderate), European Mandrake (moderate), Glucomannan (moderate) and Guar Gum (moderate).
By severity: 1 major · 7 moderate · 9 minor.
From our pharmacist’s overview on the Misoprostol page
“Misoprostol (Cytotec) is taken by mouth to protect the stomach lining from ulcers caused by NSAID pain relievers, and all 17 of its recorded supplement interactions come down to the same problem, something in the gut keeping the pill from being absorbed properly. That deserves genuine wariness, because misoprostol that never reaches th…”

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 Misoprostol
What Is Misoprostol Used For?
Brand name: Cytotec
Cytotec (misoprostol) tablets and misoprostol tablets are approved to reduce the risk of gastric ulcers (stomach ulcers) in patients who take NSAIDs — nonsteroidal anti-inflammatory drugs such as aspirin, ibuprofen, or diclofenac — and who are at high risk of ulcer complications. High-risk patients include older adults, people with serious ongoing illnesses, and those with a history of stomach ulcers.
It is important to note that misoprostol has not been shown to reduce the risk of duodenal ulcers (ulcers in the first part of the small intestine) in people taking NSAIDs. It also does not relieve the stomach pain or discomfort that NSAIDs can cause.
Most-Reported Side Effects for Misoprostol
From FAERS, the FDA’s public side-effect reporting system (16,478 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.
