Drug & supplement interaction

Phosphatidylserine + Diclofenac epolamine

Diclofenac epolamine brand names: Flector, Licart.

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 Phosphatidylserine and Diclofenac epolamine 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.

Interaction report

Phosphatidylserine and Diclofenac epolamine

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 Diclofenac epolamine and Phosphatidylserine 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.

Phosphatidylserine safety at a glance

Phosphatidylserine overall Use caution Generally well tolerated in studies, but long-term safety is not fully established.
Pregnancy Avoid There is not enough safety information, so it is best to avoid use during pregnancy.
Breastfeeding Avoid Safety while breastfeeding is unknown, so avoidance is recommended.

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

How we checked

Why No Interaction Is Listed for Diclofenac epolamine

Interactions in our licensed database are recorded against drug classes, not just single drug names. Diclofenac epolamine is filed under 10 classifications — including nonsteroidal anti-inflammatory drugs (nsaids), cytochrome p450 2c9 (cyp2c9) substrates, anticoagulant/antiplatelet drugs. Phosphatidylserine has documented interactions with 2 drug classes — the most serious being anticholinergic drugs (moderate) and cholinergic drugs (moderate) — and none of Diclofenac epolamine’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 Phosphatidylserine and Diclofenac epolamine May Share Several of the Same Side Effects

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.

    “Orally, phosphatidylserine can cause insomnia. Insomnia is more likely to occur with a higher dose of 600 mg. Headache has also been reported.”

Reported for Phosphatidylserine but not commonly for Diclofenac epolamine: stomach upset, bloating or gas and trouble sleeping.

Effects for Diclofenac epolamine come from the ADVERSE REACTIONS section of its FDA label; effects for Phosphatidylserine come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 4,258 voluntary FDA FAERS reports for Diclofenac epolamine that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

From our pharmacist’s overview on the Diclofenac epolamine page

“Even as a patch, diclofenac epolamine (Flector, Licart) is still an NSAID that reaches the bloodstream, and its 292 supplement interactions call for genuine care, six of them rated major. The bulk of the list, 202 ingredients, thins the blood or slows clotting, which stacks onto an NSAID's built-in bleeding risk.”

About Phosphatidylserine

What is Phosphatidylserine?

Phosphatidylserine
  • Memory and cognitive support
  • Age-related cognitive decline
  • Attention and focus (ADHD)
  • Mental performance under stress
  • Exercise recovery

Phosphatidylserine is a natural fat-like compound found in cell membranes, especially in the brain, and it is sold mainly to support memory and thinking. Some research suggests possible benefits for age-related memory problems, but the evidence is limited and far from conclusive. It is generally well tolerated, but check with your pharmacist or doctor before using it, especially during pregnancy or breastfeeding.

Phospholipid derived from soy lecithin, sunflower lecithin, or (historically) bovine brain · Capsules, softgels, tablets, powders

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

Phosphatidylserine: dosing

There is no official standardized dose for phosphatidylserine. Amounts used in studies have varied, and the right amount for any individual is not well established.The safest approach is to follow the dose printed on the product label and not exceed it. Taking it earlier in the day may help reduce the chance of sleep problems.

Taking Phosphatidylserine and Diclofenac epolamine Together: Common Questions

Is it safe to take Phosphatidylserine with Diclofenac epolamine?
We do not list a known interaction between Phosphatidylserine and Diclofenac epolamine. 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 Phosphatidylserine and Diclofenac epolamine have any of the same side effects?
Yes — our sources link each of them separately to 2 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 Phosphatidylserine and Diclofenac epolamine combination checked?
Interactions in our licensed database are recorded against drug classes. Diclofenac epolamine is filed under 10 classifications, and Phosphatidylserine has documented interactions with 2 drug classes — none of Diclofenac epolamine'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 Phosphatidylserine interact with any other medications?
Yes. Phosphatidylserine has 219 documented drug interactions in our database — Diclofenac epolamine 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 Diclofenac epolamine interact with any supplements?
Yes. Diclofenac epolamine has documented interactions with 292 supplements in our database — Phosphatidylserine is not one of them. The Diclofenac epolamine interaction page linked on this page lists every one, ranked by severity.
