Autumn Crocus + Ibuprofen

Ibuprofen brand names: Motrin, Children's Motrin, Advil, Children's Advil, Fenbid Forte Gel, and others.

No Known Interaction
The bottom line No known interaction

We found no known interaction between Autumn Crocus and Ibuprofen 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.

Autumn Crocus and Ibuprofen

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 Ibuprofen and Autumn Crocus 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 Ibuprofen

Interactions in our licensed database are recorded against drug classes, not just single drug names. Ibuprofen is filed under 10 classifications — including nonsteroidal anti-inflammatory drugs (nsaids), cytochrome p450 2c9 (cyp2c9) substrates, anticoagulant/antiplatelet drugs. Autumn Crocus has documented interactions with 1 drug class — the most serious being colchicine (major) — and none of Ibuprofen’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.

No Interaction Found — But Data Suggests Autumn Crocus and Ibuprofen 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.

    Ibuprofen

    Listed in the ADVERSE REACTIONS section of the FDA label for Ibuprofen, and in voluntary FDA adverse-event reports. Read the label on DailyMed ›

Reported for Autumn Crocus but not commonly for Ibuprofen: numbness or tingling, shortness of breath, a low platelet count and a low white blood cell count.

Effects for Ibuprofen come from the ADVERSE REACTIONS section of its FDA label; effects for Autumn Crocus come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 283,500 voluntary FDA FAERS reports for Ibuprofen 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 Ibuprofen page

“Most people treat ibuprofen (Advil, Motrin) as an everyday pain reliever, which is exactly why this list of 286 interacting supplements deserves real attention rather than a shrug. The dominant pattern by far is bleeding: 202 of these ingredients can add to the bleeding and stomach irritation ibuprofen already causes, and the seven maj…”

About Autumn Crocus

What is Autumn Crocus?

Autumn Crocus
  • Gout
  • Familial Mediterranean fever
  • Joint pain and inflammation
  • Rheumatoid arthritis (traditional use)

Autumn Crocus is a highly poisonous plant that contains colchicine, a compound that has real medical value but is dangerous in its raw form. You should never eat the plant or take homemade preparations from it. If you need colchicine for gout or familial Mediterranean fever, use the standardized, FDA-approved prescription product under a doctor's supervision.

Colchicum autumnale · Colchicaceae · Corm (bulb-like underground stem), seeds, and flowers · Rarely used as a raw plant or crude extract; the purified active compound (colchicine) is available only as an FDA-approved prescription medicine

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

Autumn Crocus: dosing

There is no safe established dose of the Autumn Crocus plant as a supplement, and it should not be taken in any homemade form. The colchicine content of the plant cannot be reliably measured, so even small amounts can cause serious harm.The only appropriate way to use colchicine is through an FDA-approved prescription product, which has a precise, controlled dose set by your healthcare provider.

About Ibuprofen

What Is Ibuprofen Used For?

Brand names: Motrin, Children's Motrin, Advil, Children's Advil, Fenbid Forte Gel, Ibugel Forte, Arthrofen, Ebufac, Rimafen, Calprofen, Fenpaed, Galprofen, Nurofen for Children, Orbifen for Children, Brufen, Brufen Retard, Fenbid, Tab-Profen, Ibuprofen, Calodor

Oral ibuprofen products (tablets, coated tablets, and liquid-filled capsules) are used to temporarily relieve minor aches and pains from headache, backache, toothache, muscular aches, menstrual cramps, minor arthritis pain, and the common cold, and to temporarily reduce fever. The oral prescription tablet (Ibu) is also indicated for the signs and symptoms of rheumatoid arthritis and osteoarthritis, mild to moderate pain, and primary dysmenorrhea (painful periods).

Caldolor, an intravenous (IV) form, is approved for adults and children 3 months and older to manage mild to moderate pain, to manage moderate to severe pain alongside opioid pain medicines, and to reduce fever. A separate intravenous solution, Ibuprofen Lysine, is used specifically in premature infants to close a patent ductus arteriosus (PDA) — an abnormal blood vessel connection near the heart — when standard medical management has not worked.

Taking Autumn Crocus and Ibuprofen Together: Common Questions

Is it safe to take Autumn Crocus with Ibuprofen?
We do not list a known interaction between Autumn Crocus and Ibuprofen. 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 Autumn Crocus and Ibuprofen have any of the same side effects?
Yes — our sources link each of them separately to 4 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 Autumn Crocus and Ibuprofen combination checked?
Interactions in our licensed database are recorded against drug classes. Ibuprofen is filed under 10 classifications, and Autumn Crocus has documented interactions with 1 drug class — none of Ibuprofen'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 Autumn Crocus interact with any other medications?
Yes. Autumn Crocus has 2 documented drug interactions in our database — Ibuprofen 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 Ibuprofen interact with any supplements?
Yes. Ibuprofen has documented interactions with 286 supplements in our database — Autumn Crocus is not one of them. The Ibuprofen interaction page linked on this page lists every one, ranked by severity.
