Drug & supplement interaction

Inositol + Mitotane

Mitotane brand name: Lysodren.

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 Inositol and Mitotane 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 Mitotane states a food rule worth keeping to, and 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

Inositol and Mitotane

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 Mitotane and Inositol 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.

Inositol safety at a glance

Inositol overall Generally safe Generally well tolerated at common doses, with mostly mild digestive side effects.
Pregnancy Possibly Safe When used orally and appropriately, short-term. Myo-inositol has been used with apparent safety in amounts up to 4000 mg daily during pregnancy. Read the full pregnancy detail
Breastfeeding Use caution There is not enough reliable information, so use caution and check with your doctor.

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.

How we checked

Why No Interaction Is Listed for Mitotane

Interactions in our licensed database are recorded against drug classes, not just single drug names. Mitotane is filed under a single classification — oral drugs. Inositol has documented interactions with 1 drug class — the most serious being antidiabetes drugs (moderate) — and none of Mitotane’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.

Keep it in perspective

What to actually watch for

No Interaction Found — But Data Suggests Inositol and Mitotane May Share Several of the Same Side Effects

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.

How to take them

Some Mitotane Products Have a Food Rule — Inositol Should Not Break It

At least one FDA label for a product containing Mitotane says to take it with food. If you take Inositol on an empty stomach out of habit, keep them separate — and take Mitotane 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 Mitotane 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.

2 DOSAGE AND ADMINISTRATION The recommended initial dose of LYSODREN is 2000 mg to 6000 mg orally, in three or four divided doses per day with food.

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

Everything else you take

See Every Supplement That Interacts With Mitotane

This page covers Inositol only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Mitotane 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 Mitotane page

“Mitotane (Lysodren) is chemotherapy for adrenal cancer, and doses are adjusted based on blood levels, so a supplement list like this one deserves genuine attention rather than a shrug. All 17 entries work the same basic way, by changing how much mitotane your gut actually takes in.”

About Inositol

What is Inositol?

Inositol
  • Polycystic ovary syndrome (PCOS)
  • Anxiety and panic
  • Depression and mood
  • Insulin and blood sugar support
  • Fertility support
  • Metabolic syndrome

Inositol is a sugar alcohol made naturally in the body and found in many foods, and it is sold as a supplement (often myo-inositol) mainly for PCOS, mood, and metabolic concerns. The strongest evidence is for PCOS-related symptoms, while support for other uses is more limited. It is generally well tolerated, but talk with your pharmacist or doctor before starting it, especially if you are pregnant or have a health condition.

Not applicable (a sugar alcohol found in foods and made by the body) · Capsules, tablets, powder (often as myo-inositol or D-chiro-inositol)

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

Inositol: dosing

There is no single official or standardized dose of inositol for general health. Do not assume that higher doses are better or safer.

About Mitotane

What Is Mitotane Used For?

Brand name: Lysodren

Lysodren (mitotane) tablets are indicated for the treatment of inoperable adrenocortical carcinoma (ACC) — a rare cancer of the adrenal gland's outer layer (the cortex). It can be used whether or not the tumor is actively producing hormones (functional or nonfunctional).

Because the cancer cannot be removed surgically in these patients, Lysodren works to suppress and damage the adrenal tissue itself, helping to control the disease.

Taking Inositol and Mitotane Together: Common Questions

Is it safe to take Inositol with Mitotane?
We do not list a known interaction between Inositol and Mitotane. 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 Inositol and Mitotane have any of the same side effects?
Yes — our sources link each of them separately to 5 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.
Should I take Inositol and Mitotane at the same time of day?
At least one FDA label for a product containing Mitotane says to take it with food. If you take Inositol on an empty stomach out of habit, keep them separate and take Mitotane with a meal where the label says to. Food instructions belong to the product rather than the ingredient — two Mitotane products can differ — so check the directions on your own box. This is about absorption, not an interaction.
How was the Inositol and Mitotane combination checked?
Interactions in our licensed database are recorded against drug classes. Mitotane is filed under 1 classification, and Inositol has documented interactions with 1 drug class — none of Mitotane'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 Inositol interact with any other medications?
Yes. Inositol has 86 documented drug interactions in our database — Mitotane 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 Mitotane interact with any supplements?
Yes. Mitotane has documented interactions with 17 supplements in our database — Inositol is not one of them. The Mitotane interaction page linked on this page lists every one, ranked by severity.
