California Poppy 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 California Poppy 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 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. California Poppy has documented interactions with 1 drug class — the most serious being cns depressants (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.

What to actually watch for

What California Poppy Itself Has Been Linked To

This is not an interaction — nothing below involves Amisulpride. It is the side-effect record for California Poppy on its own, from the licensed Natural Medicines monograph. If something new turns up after you add California Poppy, this list is the first place to look.

  • Joint or muscle stiffness Additional detail

    “There is currently a limited amount of information available about the adverse effects of California poppy.

    Most Common Adverse Effects:

    Orally: When used in combination with hawthorn and magnesium, California poppy has been reported to cause muscular stiffness, morning fatigue, and nausea. It is not clear if these effects are from California poppy, the other ingredients, or the combination.”

Everything above comes from the Natural Medicines adverse-effect record for California Poppy — expand a row for the licensed statement it rests on. We read the ADVERSE REACTIONS section of Amisulpride’s FDA label too, and the two lists don’t meaningfully overlap — which is why no Amisulpride column appears here.

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 California Poppy

What is California Poppy?

California Poppy
  • Anxiety and stress
  • Trouble sleeping (insomnia)
  • Mild aches and pains
  • Restlessness or nervous tension
  • Bedwetting in children (traditional use)

California poppy is a traditional herbal remedy used mainly for anxiety and sleep problems, often combined with other calming herbs. Human research is very limited, so its true benefits are not well proven. It is generally considered mild, but should be avoided during pregnancy and breastfeeding and used with caution by anyone taking sedating medicines.

Eschscholzia californica · Papaveraceae · Above-ground parts (flowers, leaves, stems) and roots · Tea, tincture, liquid extract, capsules, dried herb

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

California Poppy: dosing

There is no official, standardized dose for California poppy. Products vary widely in strength, and it is often part of herbal blends. The best approach is to follow the directions on the product label and not exceed the recommended amount.It is commonly taken in the evening when used for sleep, but timing and amount should be guided by the product and your own response.

About Amisulpride Injection

What Is Amisulpride Injection Used 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.
