Camphor + Fenoprofen Calcium
Fenoprofen Calcium brand name: Nalfon.
We found no known interaction between Camphor and Fenoprofen Calcium 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 Fenoprofen Calcium 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.
Camphor and Fenoprofen Calcium
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 Fenoprofen Calcium 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.
Camphor safety at a glance
Pregnancy & breastfeeding ratings are from Natural Medicines (Therapeutic Research Center) — the full detail is in the Special populations card below. Safety guidance is general; always confirm with your pharmacist or doctor for your situation.
Why No Interaction Is Listed for Fenoprofen Calcium
Interactions in our licensed database are recorded against drug classes, not just single drug names. Fenoprofen Calcium is filed under 5 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 Fenoprofen Calcium’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.
Camphor Does Interact With Other Medications
Camphor has 370 moderate known drug interactions in our database — Fenoprofen Calcium isn’t one of them. If you take anything else, check it against the full list below.

Some Fenoprofen Calcium Products Have a Food Rule — Camphor Should Not Break It
At least one FDA label for a product containing Fenoprofen Calcium says to take it with food. If you take Camphor on an empty stomach out of habit, keep them separate — and take Fenoprofen Calcium 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 Fenoprofen Calcium 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.
Fenoprofen Calcium may be administered with meals or with milk.

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.
What Fenoprofen Calcium 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. Fenoprofen Calcium 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.
Fenoprofen Calcium is prescribed for: Fenoprofen is used to relieve mild to moderate pain in adults. It is also used to reduce the pain, swelling, and stiffness caused by rheumatoid arthritis and osteoarthritis. These uses are supported by products including Fenoprofen Calcium, Fenopron, and Nalfon capsules. Nalfon is also available as a tablet.
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 Fenoprofen Calcium 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.
See Every Supplement That Interacts With Fenoprofen Calcium
This page covers Camphor only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Fenoprofen Calcium page lists 32 supplements it has a documented interaction with, worst first, each one explained.
The most serious there right now: Activated Charcoal (major), Asarabacca (major), Beer (major), Siberian Cocklebur (major) and Wine (major).
By severity: 5 major · 16 moderate · 11 minor.
From our pharmacist’s overview on the Fenoprofen Calcium page
“The kidneys and the stomach lining take the brunt of any NSAID, and fenoprofen calcium (Nalfon), prescribed for arthritis and other pain, is no exception. This list of 32 interacting supplements deserves real caution; five carry a major rating, and understanding those five comes first.”

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.
