Drug & supplement interaction

Phosphatidylcholine + 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 Phosphatidylcholine 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.

Phosphatidylcholine 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 Phosphatidylcholine 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.

Worth understanding: our licensed dataset holds no drug-interaction record for Phosphatidylcholine at all — not against Apixaban, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

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.

Phosphatidylcholine safety at a glance

Phosphatidylcholin... overall Use caution Generally well tolerated in food and supplement amounts, but high doses may cause digestive upset.
Pregnancy Use caution Choline is needed in pregnancy, but supplement safety beyond food sources is not well studied; check with your doctor.
Breastfeeding Use caution Not enough reliable data on supplement use while breastfeeding; speak with your healthcare provider first.

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

What to actually watch for

No Interaction Found — But Data Suggests Phosphatidylcholine 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.

  • Bleeding or bruising Worth acting on Additional detail

    Phosphatidylcholine

    “When taken orally, phosphatidylcholine may increase sweating and itching. When given subcutaneously, phosphatidylcholine can cause pain, burning, itching, tenderness to touch, bruising, edema, and erythema at the injection site. The pain, itching and erythema usually resolve within 2 days of treatment; however localized tenderness can last longer. Edema and bruising usually resolve within 10 days of treatment.”

See Every Supplement That Interacts With Apixaban

This page covers Phosphatidylcholine 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 Phosphatidylcholine

What is Phosphatidylcholine?

Phosphatidylcholine
  • Liver health
  • Memory and brain support
  • Ulcerative colitis
  • Source of choline
  • High cholesterol

Phosphatidylcholine is a phospholipid that is part of every cell membrane and a source of choline. People take it for liver, brain, and gut health, but solid human evidence is limited for most uses. It is generally well tolerated, but talk to your pharmacist or doctor before starting it.

Phospholipid derived from sources such as soybeans, sunflower, and egg yolk · Capsules, softgels, tablets, granules, liquid, and powder (sometimes as part of lecithin)

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

Phosphatidylcholine: dosing

There is no single official or standardized dose of phosphatidylcholine for supplement use. The amount in products varies widely depending on the source and form, and the studied amounts differ from one condition to another.The best approach is to follow the dosing directions on your specific product's label. Higher doses are more likely to cause stomach upset and other side effects.

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 Phosphatidylcholine and Apixaban Together: Common Questions

Is it safe to take Phosphatidylcholine with Apixaban?
We do not list a known interaction between Phosphatidylcholine 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 Phosphatidylcholine 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.
Does Apixaban interact with any supplements?
Yes. Apixaban has documented interactions with 285 supplements in our database — Phosphatidylcholine is not one of them. The Apixaban interaction page linked on this page lists every one, ranked by severity.
