Drug & supplement interaction

Naproxen brand names: Naprosyn, Naprelan, Anaprox, Anaprox DS, Naproxyn, and others.

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 Glutathione and Naproxen 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.

Glutathione and Naproxen

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 Naproxen and Glutathione 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 Glutathione at all — not against Naproxen, 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.

Glutathione safety at a glance

Glutathione overall Use caution Oral forms appear generally well tolerated short-term, but long-term safety and the safety of IV and inhaled forms are less clear.
Pregnancy Avoid There is not enough reliable safety information, so it is best avoided during pregnancy unless your doctor advises otherwise.
Breastfeeding Avoid There is not enough reliable safety information during breastfeeding, so caution and avoidance are advised.

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 Glutathione and Naproxen 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. 2 of them are worth acting on rather than waiting out — marked below.

Effects for Naproxen come from the ADVERSE REACTIONS section of its FDA label; effects for Glutathione come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 165,062 voluntary FDA FAERS reports for Naproxen 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.

Overlapping uses

What Naproxen Is Prescribed For, and What Glutathione Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Naproxen is a prescription medicine with approved uses on its FDA label. Glutathione is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Naproxen is prescribed for: Naproxen tablets, naproxen sodium tablets, and naproxen oral suspension are used to relieve the signs and symptoms of rheumatoid arthritis, osteoarthritis, ankylosing spondylitis, and polyarticular juvenile idiopathic arthritis. They are also used for tendonitis, bursitis, and acute gout, and for managing pain and primary dysmenorrhea (menstrual cramps). Naproxen Sodium Controlled-Release Tablets are indicated for the same conditions plus the relief of mild to moderate pain. Several over-the-counter naproxen sodium products are indicated for the temporary relief of minor aches and pains from headache, backache, muscular aches, toothache, menstrual cramps, minor arthritis pain, and the common cold, and to temporarily reduce fever.

Glutathione has been studied for:

  • Osteoarthritis studied, not established Glutathione has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Glutathione for osteoarthritis

    Although there is interest in using oral glutathione for osteoarthritis, there is insufficient reliable information about the clinical effects of glutathione for this condition.

Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Naproxen on your own; if you are taking Glutathione for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

About Glutathione

What is Glutathione?

Glutathione
  • Antioxidant support
  • Skin lightening or brightening
  • Detoxification support
  • Immune support
  • Liver health
  • Anti-aging

Glutathione is a powerful antioxidant your body makes naturally, and many people take it as a supplement hoping for skin, detox, or anti-aging benefits. However, strong human evidence is limited for most uses, and oral glutathione is poorly absorbed. Talk to your pharmacist or doctor before starting, especially if you are considering IV or inhaled forms.

Not applicable (a compound made of three amino acids: cysteine, glutamic acid, and glycine) · Oral capsules and tablets, liposomal liquid, lozenges, intravenous (IV) injections, nebulized (inhaled) forms, topical creams

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

Glutathione: dosing

There is no official, standardized dose of glutathione for any health condition. Supplement products vary widely in their form and amount.The best advice is to follow the directions on the product label and not exceed them. Because oral glutathione is poorly absorbed, taking more does not necessarily mean more benefit.IV and inhaled forms should only be used under the care of a healthcare provider.

Taking Glutathione and Naproxen Together: Common Questions

Is it safe to take Glutathione with Naproxen?
We do not list a known interaction between Glutathione and Naproxen. 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 Glutathione and Naproxen have any of the same side effects?
Yes — our sources link each of them separately to 3 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.
Are Glutathione and Naproxen used for the same thing?
They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together. This page lists the shared uses and how strong the evidence is for Glutathione in each. That is a conversation for your prescriber, especially if Naproxen is being adjusted to a target.
Does Naproxen interact with any supplements?
Yes. Naproxen has documented interactions with 311 supplements in our database — Glutathione is not one of them. The Naproxen interaction page linked on this page lists every one, ranked by severity.
