Lemongrass and Amisulpride

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 Amisulpride and Lemongrass 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.

Breastfeeding Use caution Not enough reliable data; avoid medicinal amounts and stick to occasional food use.

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 Amisulpride

Interactions in our licensed database are recorded against drug classes, not just single drug names. Amisulpride is filed under a single classification — qt interval-prolonging drugs. Lemongrass has documented interactions with 3 drug classes — the most serious being cytochrome p450 3a4 (cyp3a4) substrates (moderate), glucuronidated drugs (moderate) and pentobarbital (nembutal) (moderate) — and none of Amisulpride’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.

  • Low potassium Worth acting on
  • A slow heartbeat Worth acting on
  • An irregular heartbeat Worth acting on
  • Confusion Worth acting on
  • Seizures Worth acting on
  • A severe allergic reaction Worth acting on
  • Hives Worth acting on
  • A low white blood cell count Worth acting on

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

Overlapping uses

What Amisulpride Is Prescribed For, and What Lemongrass Has Been Studied For

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

Amisulpride is prescribed for: Barhemsys (amisulpride injection) is approved for adults to prevent postoperative nausea and vomiting (PONV) — nausea and vomiting that can occur after surgery and anesthesia. It can be used alone or alongside another anti-nausea medicine from a different drug class. Barhemsys is also used to treat PONV when it occurs after surgery, either in patients who already received a different anti-nausea medicine as prevention, or in patients who received no preventive anti-nausea treatment at all.

Lemongrass has been studied for:

  • Nausea and vomiting studied, not established Lemongrass has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Lemongrass for nausea and vomiting

    Although there has been interest in using oral lemongrass for nausea and vomiting, there is insufficient reliable information about the clinical effects of lemongrass for this purpose.

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 Amisulpride on your own; if you are taking Lemongrass for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

From our pharmacist’s overview on the Amisulpride page

“Amisulpride (Barhemsys), given to prevent or treat nausea and vomiting after surgery, already carries its own warning about the heart's electrical rhythm. Every one of the 13 supplements and herbs on this list pushes the same way, lengthening the QT interval and raising the chance of a dangerous heart rhythm, so this is a list that des…”

About Lemongrass

What is Lemongrass?

Lemongrass
  • Digestive upset
  • Anxiety and stress
  • Antimicrobial/antifungal
  • Insect repellent
  • Flavoring in food and drinks

Lemongrass is a fragrant tropical grass widely used as a cooking herb, a tea, and an aromatherapy oil. It is generally considered safe in the small amounts used in food, but most of its claimed health benefits come from laboratory or animal studies rather than strong human research. Talk with your pharmacist or doctor before using concentrated supplements or the essential oil, especially if you are pregnant or breastfeeding.

Cymbopogon citratus · Poaceae · Leaves, stalks, and essential oil · Tea, fresh or dried herb, capsules, essential oil, topical preparations

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

Lemongrass: dosing

There is no official standardized dose for lemongrass. The amount used depends on the form, such as tea, capsule, or essential oil.For tea, people commonly steep a small amount of dried or fresh leaves in hot water. For supplements, follow the directions on the product label, since strength varies from brand to brand.

They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together.

Interactions in our licensed database are recorded against drug classes. Amisulpride is filed under 1 classification, and Lemongrass has documented interactions with 3 drug classes — none of Amisulpride'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.
