Avocado Sugar Extract and Amantadine

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 Amantadine 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 Amantadine

Interactions in our licensed database are recorded against drug classes, not just single drug names. Amantadine is filed under 2 classifications — anticholinergic drugs, oral drugs. Avocado Sugar Extract has documented interactions with 1 drug class — the most serious being antidiabetes drugs (moderate) — and none of Amantadine’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 Amantadine’s Own FDA Label Lists

These are the most notable effects listed in the ADVERSE REACTIONS section of Amantadine’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. 8 of them are worth acting on rather than waiting out — marked below.

  • Unsteadiness Worth acting on mentioned in 5.9% of FDA reports for Amantadine
  • Hallucinations Worth acting on mentioned in 7.7% of FDA reports for Amantadine
  • Trouble swallowing Worth acting on

Showing the 10 most notable of 26 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 Amantadine. Read the label on DailyMed › Where a percentage is shown, it is the share of 20,186 voluntary FDA FAERS reports for Amantadine that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. 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.

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.

Most-Reported Side Effects for Amantadine
