Avocado Sugar Extract and Isocarboxazid

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 Isocarboxazid and Avocado Sugar Extract 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 Isocarboxazid

Interactions in our licensed database are recorded against drug classes, not just single drug names. Isocarboxazid is filed under 5 classifications — including monoamine oxidase inhibitors (maois), antidepressant drugs, serotonergic drugs. Avocado Sugar Extract has documented interactions with 1 drug class — the most serious being antidiabetes drugs (moderate) — and none of Isocarboxazid’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 Isocarboxazid’s Own FDA Label Lists

This is not an interaction — none of it involves Avocado Sugar Extract. These are the most notable effects listed in the ADVERSE REACTIONS section of Isocarboxazid’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.

  • Dry mouth
  • Dizziness
  • Nausea

From the ADVERSE REACTIONS section of the FDA label for Isocarboxazid. Read the label on DailyMed › Avocado Sugar Extract’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Avocado Sugar Extract side to compare — that is a limit of the record, not a statement that Avocado Sugar Extract has no side effects.

Everything else you take

See Every Supplement That Interacts With Isocarboxazid

This page covers Avocado Sugar Extract only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Isocarboxazid page lists 81 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Beer (major), Bitter Orange (major), Brewer's Yeast (major) and Cowhage (major).

By severity: 14 major · 55 moderate · 12 minor.

From our pharmacist’s overview on the Isocarboxazid page

“Isocarboxazid (Marplan) is an MAOI antidepressant, and that drug class carries some of the sharpest supplement and food hazards in the pharmacy, so read this list closely rather than skimming it. Fourteen of the 81 entries rate major, and most of the danger runs through tyramine.”

About Avocado Sugar Extract

What is Avocado Sugar Extract?

  • Blood sugar support
  • Weight management
  • Healthy aging/longevity interest
  • Metabolic support
  • Athletic/animal supplement formulas

Avocado sugar extract is a source of D-mannoheptulose, an unusual sugar studied mainly in laboratory and animal research for its possible effects on glucose metabolism. Human evidence is very limited, so it should not be relied on to treat diabetes or any condition. Talk with your pharmacist or doctor before using it, especially if you have blood sugar concerns.

Persea americana · Lauraceae · Fruit (avocado pulp) · Capsules, powders, and standardized extracts; sometimes included in supplement blends

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

Avocado Sugar Extract: dosing

There is no established standardized dose for avocado sugar extract or D-mannoheptulose in humans. Products vary widely in how much extract they contain and how it is standardized.If you choose to use it, follow the directions on the product label and do not exceed them.

About Isocarboxazid

What Is Isocarboxazid Used For?

Brand name: Marplan

Marplan (isocarboxazid) is indicated for the treatment of depression — specifically, major depressive disorder. Because it carries serious risks, it is not a first-choice antidepressant. Marplan is generally reserved for patients who have not responded adequately to other antidepressants.

Clinical trials showed Marplan to be effective in adult outpatients with major depressive disorder, including those whose depression was accompanied by anxiety symptoms such as panic or phobias. Marplan is not approved for use in children or adolescents.
