Drug & supplement interaction

Spearmint + Galantamine

Galantamine brand names: Reminyl, Razadyne.

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 Spearmint and Galantamine 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 Galantamine 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

Spearmint and Galantamine

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 Galantamine and Spearmint 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 Galantamine

Interactions in our licensed database are recorded against drug classes, not just single drug names. Galantamine is filed under 5 classifications — including acetylcholinesterase (ache) inhibitors, cholinergic drugs, cytochrome p450 2d6 (cyp2d6) substrates. Spearmint has documented interactions with 2 drug classes — the most serious being cns depressants (moderate) and hepatotoxic drugs (moderate) — and none of Galantamine’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

No Interaction Found — But Data Suggests Spearmint and Galantamine 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.

  • Stomach upset / Diarrhea Additional detail

    Spearmint

    “Orally, taking spearmint extract 600 mg daily has been associated with dyspepsia in one clinical trial. Taking a higher dose of 900 mg daily has been associated with diarrhea and belching. Drinking 2 cups of spearmint tea with normal amounts of rosmarinic acid has been associated with one report of dry mouth in clinical research.”

Reported for Spearmint but not commonly for Galantamine: increased appetite, constipation, a fast or pounding heartbeat and weight gain.

Effects for Galantamine come from the ADVERSE REACTIONS section of its FDA label; effects for Spearmint come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 3,188 voluntary FDA FAERS reports for Galantamine that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

Special populations

Spearmint in Pregnancy & Breastfeeding

Pregnancy Likely Safe

When used in the amounts commonly found in foods.

Pregnancy Possibly Unsafe

When used orally during pregnancy in excessive amounts. Animal research suggests that spearmint tea may cause uterine damage. Avoid using in amounts greater than those typically found in foods during pregnancy.

Lactation Likely Safe

When used in the amounts commonly found in foods. There is insufficient reliable information available about the safety of spearmint during lactation. Avoid using in amounts greater than those typically found in foods.

How to take them

Some Galantamine Products Have a Food Rule — Spearmint Should Not Break It

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

( 2.1 ) Take with food; ensure adequate fluid intake during treatment (2.1) Hepatic impairment: should not exceed 16 mg/day for moderate hepatic impairment; do not use in patients with severe hepatic impairment ( 2.2 ) Renal impairment: should not exceed 16 mg/day for creatinine clearance 9 to 59 mL/min; do not use in patients with creatinine clearance less than 9 mL/min.

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

Overlapping uses

What Galantamine Is Prescribed For, and What Spearmint Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Galantamine is a prescription medicine with approved uses on its FDA label. Spearmint is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Galantamine is prescribed for: Galantamine — available as extended-release capsules, tablets, and an oral solution — is used to treat mild to moderate dementia caused by Alzheimer's disease. All supported formulations share this indication. It does not cure or slow the underlying disease, but it can help support cognitive function in people with early to moderate-stage Alzheimer's. Its benefits may lessen as the disease progresses and more brain cells are lost.

Spearmint has been studied for:

  • Cognitive function studied, not established Spearmint has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Spearmint for cognitive function

    Small clinical studies suggest that oral spearmint extract or spearmint-flavored gum may not improve most measures of cognitive function.

Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Galantamine on your own; if you are taking Spearmint for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

Everything else you take

See Every Supplement That Interacts With Galantamine

This page covers Spearmint only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Galantamine page lists 170 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Grapefruit (major), St. John's Wort (major), 1,3-dmaa (moderate) and Acacia Rigidula (moderate).

By severity: 3 major · 126 moderate · 41 minor.

From our pharmacist’s overview on the Galantamine page

“Galantamine (Razadyne) treats Alzheimer's disease, so it is often a caregiver filling the pill organizer alongside memory supplements and morning juice. That pairing deserves genuine care, because three of the 170 supplement ingredients on file are rated major and two of them are everyday items.”

About Spearmint

What is Spearmint?

Spearmint
  • Digestive upset and indigestion
  • Nausea
  • Hormonal acne and unwanted hair (PCOS-related)
  • Memory and focus
  • Mild stress and anxiety
  • Joint discomfort

Spearmint is a common culinary mint that is generally safe in food and tea amounts. Early research suggests possible benefits for digestion, mild hormone-related issues (such as excess facial hair in women), and memory, but the evidence is still limited. Talk to your pharmacist or doctor before using concentrated supplements, especially if you are pregnant or have a health condition.

Mentha spicata · Lamiaceae · Leaves and essential oil · Tea, capsules, dried leaf, essential oil, extract

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

Spearmint: dosing

There is no official standard dose for spearmint. In research, people have used it as a cup of tea once or twice a day, or as standardized extracts in capsules. Because products vary widely in strength, it is best to follow the directions on the product label.Spearmint supplements are sometimes standardized to a certain amount of rosmarinic acid. Start low and watch how your body responds.

Taking Spearmint and Galantamine Together: Common Questions

Is it safe to take Spearmint with Galantamine?
We do not list a known interaction between Spearmint and Galantamine. 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 Spearmint and Galantamine have any of the same side effects?
Yes — our sources link each of them separately to 3 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 Spearmint and Galantamine at the same time of day?
At least one FDA label for a product containing Galantamine says to take it with food. If you take Spearmint on an empty stomach out of habit, keep them separate and take Galantamine with a meal where the label says to. Food instructions belong to the product rather than the ingredient — two Galantamine products can differ — so check the directions on your own box. This is about absorption, not an interaction.
Are Spearmint and Galantamine used for the same thing?
They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together. This page lists the shared uses and how strong the evidence is for Spearmint in each. That is a conversation for your prescriber, especially if Galantamine is being adjusted to a target.
How was the Spearmint and Galantamine combination checked?
Interactions in our licensed database are recorded against drug classes. Galantamine is filed under 5 classifications, and Spearmint has documented interactions with 2 drug classes — none of Galantamine'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 Spearmint interact with any other medications?
Yes. Spearmint has 579 documented drug interactions in our database — Galantamine 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 Galantamine interact with any supplements?
Yes. Galantamine has documented interactions with 170 supplements in our database — Spearmint is not one of them. The Galantamine interaction page linked on this page lists every one, ranked by severity.
