The bottom line No known interaction

We found no known interaction between Cereus and Apixaban 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.

Cereus and Apixaban

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 Apixaban and Cereus 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.

Cereus safety at a glance

Cereus overall Use caution Limited safety data and possible effects on the heart make professional guidance important.
Pregnancy Avoid Not enough safety information; avoid during pregnancy.
Breastfeeding Avoid No reliable safety data, so avoid while breastfeeding.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Apixaban

Interactions in our licensed database are recorded against drug classes, not just single drug names. Apixaban is filed under 4 classifications — including anticoagulant/antiplatelet drugs, p-glycoprotein substrates, cytochrome p450 3a4 (cyp3a4) substrates. Cereus has documented interactions with 2 drug classes — the most serious being digoxin (lanoxin) (moderate) and monoamine oxidase inhibitors (maois) (moderate) — and none of Apixaban’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.

Keep it in perspective

What to actually watch for

What Cereus Itself Has Been Linked To

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

  • Itching / Diarrhea / Vomiting / Nausea Additional detail

    “Orally, fresh cereus juice may cause burning of the mouth, queasiness, nausea, vomiting, and diarrhea (4,18).

    Topically, it may cause itching and skin pustules (18).”

    Cereus · Natural Medicines adverse-effect record, reported in diarrhea.

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

See Every Supplement That Interacts With Apixaban

This page covers Cereus only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Apixaban page lists 285 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Danshen (major), Grapefruit (major), Piracetam (major) and St. John's Wort (major).

By severity: 5 major · 240 moderate · 40 minor.

From our pharmacist’s overview on the Apixaban page

“St. John's wort can weaken apixaban (Eliquis), speeding how the body clears this blood thinner and leaving you less protected from the strokes and clots it is prescribed to prevent.”

About Cereus

What is Cereus?

  • Heart palpitations
  • Mild heart symptoms
  • Anxiety and nervous tension
  • Shortness of breath
  • Fluid retention

Cereus (often called night-blooming cereus) is a cactus traditionally used in folk and homeopathic medicine for heart-related complaints like palpitations. High-quality human evidence supporting these uses is lacking, and because it may affect the heart, it should be used only under medical guidance. Pregnant and breastfeeding people should avoid it.

Selenicereus grandiflorus · Cactaceae · Flowers and young stems · Tincture, liquid extract, capsules, homeopathic preparations

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

Cereus: dosing

There is no established standard dose of Cereus. Products vary widely in strength, and homeopathic preparations are very different from herbal tinctures.If you choose to use a Cereus product, follow the directions on the label and do not exceed them.

From our Cereus monograph — the full record covers uses, side effects and every documented interaction.

About Apixaban

What Is Apixaban Used For?

Brand name: Eliquis

Apixaban is used to reduce the risk of stroke and dangerous clots traveling through the body in adults with nonvalvular atrial fibrillation (an irregular heart rhythm not caused by a heart valve problem). It is also used to prevent deep vein thrombosis (DVT — a blood clot in the leg) in adults after hip or knee replacement surgery, and to treat DVT and pulmonary embolism (PE — a blood clot in the lungs) in adults, including reducing the risk of those clots coming back.

Eliquis (the brand-name tablet and kit) is additionally approved to treat venous thromboembolism (VTE — blood clots in the veins) and reduce the risk of recurrent VTE in pediatric patients from birth and older, after at least 5 days of initial anticoagulant treatment. The generic apixaban tablet carries the adult indications only.
