Catnip + 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 Catnip 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.

Catnip 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 Catnip 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.

Catnip safety at a glance

Catnip overall Use caution Likely fine for most adults in tea amounts, but human safety data are limited.
Pregnancy Avoid Avoid during pregnancy, as it may stimulate the uterus and safety is not established.
Breastfeeding Avoid Not enough safety information is available, so it is best avoided.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

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. Catnip has documented interactions with 2 drug classes — the most serious being cns depressants (moderate) and lithium (moderate) — 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 Catnip 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.

Reported for Catnip but not commonly for Ibuprofen: mood changes or irritability and tiredness.

Effects for Ibuprofen come from the ADVERSE REACTIONS section of its FDA label; effects for Catnip 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.

Overlapping uses

What Ibuprofen Is Prescribed For, and What Catnip Has Been Studied For

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

Ibuprofen is prescribed for: 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.

Catnip has been studied for:

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

    Catnip for osteoarthritis

    Although there has been interest in using topical catnip for osteoarthritis, there is insufficient reliable information about the clinical effects of catnip for this purpose.

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

    Catnip for common cold

    Although there has been interest in using oral catnip for common cold, there is insufficient reliable information about the clinical effects of catnip for this purpose.

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 Ibuprofen on your own; if you are taking Catnip 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 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.

About Catnip

What is Catnip?

Catnip
  • Sleep and insomnia
  • Anxiety and stress
  • Digestive upset
  • Cold and flu symptoms
  • Insect repellent

Catnip is a mint-family herb most often used as a calming tea for sleep, anxiety, and minor digestive upset, but solid human research supporting these uses is lacking. It is generally considered fairly safe in small culinary or tea amounts for most adults, but it should be avoided during pregnancy and used cautiously otherwise. Talk to your pharmacist or doctor before using it, especially if you take medications or have a health condition.

Nepeta cataria · Lamiaceae · Leaves, flowers, and essential oil · Tea, capsules, tincture, dried herb, essential oil

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

Catnip: dosing

There is no well-established standard dose for catnip. Amounts used in traditional practice vary widely, and reliable dosing guidelines from clinical studies are not available.The safest approach is to follow the directions on the product label and not exceed the recommended amount.

Taking Catnip and Ibuprofen Together: Common Questions

Is it safe to take Catnip with Ibuprofen?
We do not list a known interaction between Catnip 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 Catnip and Ibuprofen have any of the same side effects?
Yes — our sources link each of them separately to 2 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 Catnip and Ibuprofen 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 Catnip in each. That is a conversation for your prescriber, especially if Ibuprofen is being adjusted to a target.
How was the Catnip and Ibuprofen combination checked?
Interactions in our licensed database are recorded against drug classes. Ibuprofen is filed under 10 classifications, and Catnip has documented interactions with 2 drug classes — 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 Catnip interact with any other medications?
Yes. Catnip has 248 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 — Catnip is not one of them. The Ibuprofen interaction page linked on this page lists every one, ranked by severity.
