Drug & supplement interaction

New Zealand Green-lipped Mussel + Oxycodone

Oxycodone brand names: OxyContin, Roxicodone, OxyIR, Percolone, Oxecta, and others.

No Known Interaction
The bottom line No known interaction

We found no known interaction between New Zealand Green-lipped Mussel and Oxycodone 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 label for Oxycodone states a food rule worth keeping to, and 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.

New Zealand Green-lipped Mussel and Oxycodone

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 Oxycodone and New Zealand Green-lipped Mussel 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 New Zealand Green-lipped Mussel at all — not against Oxycodone, 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.

What to actually watch for

No Interaction Found — But Data Suggests New Zealand Green-lipped Mussel and Oxycodone 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. One of them is worth acting on rather than waiting out — marked below.

How to take them

Some Oxycodone Products Have a Food Rule — New Zealand Green-lipped Mussel Should Not Break It

At least one FDA label for a product containing Oxycodone says to take it with food. If you take New Zealand Green-lipped Mussel on an empty stomach out of habit, keep them separate — and take Oxycodone with a meal where the label says to.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Oxycodone products can carry different directions, and extended-release forms often differ from immediate-release ones. The label we read is quoted below — check the directions on your own box or bottle, or ask your pharmacist, for how to take the exact product you were given.

( 2.2 , 5.1 , 5.2 , 5.3 ) XTAMPZA ER is administered, twice daily, every 12 hours, and must be taken with food .

From the Dosage and Administration section of the FDA label we read for Oxycodone — where that label names a specific product, the instruction is that product's. Read the label on DailyMed ›

A food rule is not an interaction — it is about how much of the medicine you absorb. The directions that came with your own product, and your pharmacist, outrank anything on this page.

See Every Supplement That Interacts With Oxycodone

This page covers New Zealand Green-lipped Mussel only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Oxycodone page lists 145 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: 1,4-butanediol (major), Activated Charcoal (major), Beer (major), Gamma-hydroxybutyrate (ghb) (major) and Kava (major).

By severity: 8 major · 114 moderate · 23 minor.

From our pharmacist’s overview on the Oxycodone page

“Oxycodone is a potent opioid painkiller, and anything that deepens its sedation can slow breathing itself, which is why this list deserves genuine respect. Of the 145 supplement and herbal ingredients on record, eight rate major, and the biggest cluster by far, 78 ingredients, adds extra drowsiness on top of the opioid's own.”

About New Zealand Green-lipped Mussel

What is New Zealand Green-lipped Mussel?

  • Osteoarthritis joint pain
  • Rheumatoid arthritis symptoms
  • Joint stiffness and mobility
  • General anti-inflammatory support
  • Mild asthma support

New Zealand green-lipped mussel is a shellfish-derived supplement rich in omega-3 fats that is mostly used for joint pain and arthritis. Some studies suggest a modest benefit for osteoarthritis, but the evidence is mixed and not strong. It is generally well tolerated in healthy adults, but people with shellfish allergy should avoid it, and pregnant or breastfeeding people should not use it without medical advice.

Perna canaliculus · Mytilidae · Edible mussel flesh (often as a freeze-dried powder or lipid/oil extract) · Capsules, softgels (lipid extract), powder, tablets

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

New Zealand Green-lipped Mussel: dosing

There is no official or standardized dose for green-lipped mussel, and products vary widely in strength and form (powder versus lipid extract). Because of this, the best approach is to follow the directions on the product label.Dosing depends on whether you are using a whole-mussel powder or a concentrated oil extract, so the amounts are not interchangeable.

About Oxycodone

What Is Oxycodone Used For?

Brand names: OxyContin, Roxicodone, OxyIR, Percolone, Oxecta, OxyNeo

Oxycodone treats pain that is severe enough to need an opioid pain medicine, when other treatments are not enough. Other options include non-opioid pain relievers or opioid combination products.

Some products are for specific situations. Extended-release products (OxyContin, Xtampza ER, and oxycodone extended-release tablets) are for severe, persistent pain that needs daily, around-the-clock treatment. They are not for as-needed use. The 100 mg per 5 mL (20 mg/mL) oral solution is only for opioid-tolerant patients. Oxaydo is labeled for acute and chronic pain.

Taking New Zealand Green-lipped Mussel and Oxycodone Together: Common Questions

Is it safe to take New Zealand Green-lipped Mussel with Oxycodone?
We do not list a known interaction between New Zealand Green-lipped Mussel and Oxycodone. 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 New Zealand Green-lipped Mussel and Oxycodone have any of the same side effects?
Yes — our sources link each of them separately to 7 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.
Should I take New Zealand Green-lipped Mussel and Oxycodone at the same time of day?
At least one FDA label for a product containing Oxycodone says to take it with food. If you take New Zealand Green-lipped Mussel on an empty stomach out of habit, keep them separate and take Oxycodone with a meal where the label says to. Food instructions belong to the product rather than the ingredient — two Oxycodone products can differ — so check the directions on your own box. This is about absorption, not an interaction.
Does Oxycodone interact with any supplements?
Yes. Oxycodone has documented interactions with 145 supplements in our database — New Zealand Green-lipped Mussel is not one of them. The Oxycodone interaction page linked on this page lists every one, ranked by severity.
