Drug & supplement interaction

Squill + Apixaban

Apixaban brand name: Eliquis.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between Squill 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. Additionally, although there is no interaction, 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.

Squill 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 Squill 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 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. Squill has documented interactions with 7 drug classes — the most serious being digoxin (lanoxin) (major), corticosteroids (moderate) and diuretic drugs (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.

What to actually watch for

No Interaction Found — But Data Suggests Squill and Apixaban May Share a Side Effect

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. One of them is worth acting on rather than waiting out — marked below.

    “Orally, squill can cause irregular pulse (18,94852).

    Squill poisoning resembles digoxin poisoning. The cardiovascular symptoms of squill poisoning include cardiac arrest and life-threatening arrhythmias, including ventricular tachycardia, atrial tachycardia with atrioventricular block, and ventricular fibrillation (18,3488).”

See Every Supplement That Interacts With Apixaban

This page covers Squill 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 Squill

What is Squill?

Squill
  • Cough and chest congestion
  • Fluid retention (diuretic)
  • Heart conditions (traditional 'cardiac tonic')
  • Hair loss (topical use)
  • Rodenticide (red squill, non-medicinal)

Squill is a bulb plant that contains potent cardiac glycosides, which can affect the heart much like the drug digoxin. While it has a long history of use as a cough remedy and heart tonic, it can be dangerously toxic and there is little solid evidence for its modern use, so we do not recommend taking it without close medical supervision.

Drimia maritima · Asparagaceae · Dried inner bulb scales · Dried bulb, tinctures, liquid extracts, syrups, and some traditional cough preparations

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

Squill: dosing

There is no well-established, standardized safe dose of squill for general use. Because the active compounds are so potent and the toxic dose is close to any possibly effective dose, self-dosing is not recommended.If a product contains squill, follow the label exactly and do not take more than directed.

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.

Taking Squill and Apixaban Together: Common Questions

Is it safe to take Squill with Apixaban?
We do not list a known interaction between Squill and Apixaban. 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 Squill and Apixaban have any of the same side effects?
Yes — our sources link each of them separately to one 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.
How was the Squill and Apixaban combination checked?
Interactions in our licensed database are recorded against drug classes. Apixaban is filed under 4 classifications, and Squill has documented interactions with 7 drug classes — none of Apixaban'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 Squill interact with any other medications?
Yes. Squill has 156 documented drug interactions in our database — Apixaban 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 Apixaban interact with any supplements?
Yes. Apixaban has documented interactions with 285 supplements in our database — Squill is not one of them. The Apixaban interaction page linked on this page lists every one, ranked by severity.
