Drug & supplement interaction

Camphor + Oxaprozin

Oxaprozin brand name: Daypro.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 20, 2026
The bottom line No known interaction

We found no known interaction between Camphor and Oxaprozin 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

Camphor and Oxaprozin

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 Oxaprozin and Camphor 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 Oxaprozin

Interactions in our licensed database are recorded against drug classes, not just single drug names. Oxaprozin is filed under 6 classifications — including nonsteroidal anti-inflammatory drugs (nsaids), organic anion transporter 3 (oat3) substrates, organic anion transporter 1 (oat1) substrates. Camphor has documented interactions with 1 drug class — the most serious being hepatotoxic drugs (moderate) — and none of Oxaprozin’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 Camphor and Oxaprozin 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. 7 of them are worth acting on rather than waiting out — marked below.

  • Wheezing / Shortness of breath Worth acting on Additional detail

    Camphor

    “When inhaled in large enough concentrations, camphor can irritate the nose and sinuses. However, it is difficult to determine a safe concentration of inhaled camphor.

    A 54-year-old females with a history of asthma developed shortness of breath, hypoxemia, and respiratory acidosis after oral ingestion of Vicks VapoRub, containing 4.8% camphor.”

Showing the 10 most notable of 11 shared effects — ranked by how unusual each one is, not just whether both lists mention it.

Reported for Camphor but not commonly for Oxaprozin: mood changes or irritability.

Effects for Oxaprozin come from the ADVERSE REACTIONS section of its FDA label; effects for Camphor come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 883 voluntary FDA FAERS reports for Oxaprozin 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 Oxaprozin Is Prescribed For, and What Camphor Has Been Studied For

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

Oxaprozin is prescribed for: Oxaprozin treats the signs and symptoms of osteoarthritis, rheumatoid arthritis, and juvenile rheumatoid arthritis — reducing joint pain, swelling, and stiffness. These uses are shared across available oral formulations, including Coxanto capsules, Oxaprozin capsules, and Oxaprozin tablets (including Daypro). Juvenile rheumatoid arthritis dosing for children ages 6 to 16 is weight-based and has been studied with both the capsule and tablet formulations.

Camphor has been studied for:

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

    Camphor for osteoarthritis

    Although topical camphor is approved for use in the management of acute pain due to its counterirritant effects, it is unclear if it is beneficial for knee osteoarthritis.

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 Oxaprozin on your own; if you are taking Camphor for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

From our pharmacist’s overview on the Oxaprozin page

“I would put oxaprozin (Daypro), a long-acting NSAID prescribed for arthritis pain, in the read-carefully category. The interactions that concern me most pile onto the drug's own weak spots: alcohol, meaning the beer and wine entries below, raises the odds of stomach bleeding on any NSAID, and several kidney-stressing herbs can deepen t…”

About Camphor

What is Camphor?

  • Muscle and joint aches
  • Cough and chest congestion
  • Itching and skin irritation
  • Cold sores or minor wounds
  • Counterirritant for pain

Camphor is a strong-smelling compound from the camphor tree (or made synthetically) that is used in many topical rub-on products for muscle aches, itching, and chest congestion. It can be helpful for these uses when applied to the skin in small, regulated amounts, but it is toxic and potentially deadly if swallowed, so it should never be taken by mouth. Keep camphor products away from children and check with a pharmacist before use.

Cinnamomum camphora · Lauraceae · Wood, bark, and essential oil (camphor is also made synthetically) · Topical creams, ointments, balms, salves, vapor rubs, oils, inhalants, and liniments

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

Camphor: dosing

There is no established 'supplement' dose for camphor because it should not be taken by mouth. For skin products, the amount of camphor is regulated and listed on the label. Over-the-counter topical products typically contain camphor at low percentages.Always follow the directions on the product label, and do not apply more often or in larger amounts than directed. Use only finished products meant for skin use — never raw or homemade camphor preparations.

Taking Camphor and Oxaprozin Together: Common Questions

Is it safe to take Camphor with Oxaprozin?
We do not list a known interaction between Camphor and Oxaprozin. 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 Camphor and Oxaprozin have any of the same side effects?
Yes — our sources link each of them separately to 10 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 Camphor and Oxaprozin 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 Camphor in each. That is a conversation for your prescriber, especially if Oxaprozin is being adjusted to a target.
How was the Camphor and Oxaprozin combination checked?
Interactions in our licensed database are recorded against drug classes. Oxaprozin is filed under 6 classifications, and Camphor has documented interactions with 1 drug class — none of Oxaprozin'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 Camphor interact with any other medications?
Yes. Camphor has 370 documented drug interactions in our database — Oxaprozin 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 Oxaprozin interact with any supplements?
Yes. Oxaprozin has documented interactions with 52 supplements in our database — Camphor is not one of them. The Oxaprozin interaction page linked on this page lists every one, ranked by severity.
