Drug & supplement interaction

Elecampane + Ketorolac Tromethamine

Ketorolac Tromethamine brand names: Toradol, Acuvail.

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 Elecampane and Ketorolac Tromethamine 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

Elecampane and Ketorolac Tromethamine

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 Ketorolac Tromethamine and Elecampane 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 Ketorolac Tromethamine

Interactions in our licensed database are recorded against drug classes, not just single drug names. Ketorolac Tromethamine is filed under 6 classifications — including nonsteroidal anti-inflammatory drugs (nsaids), organic anion transporter 3 (oat3) substrates, organic anion transporter 1 (oat1) substrates. Elecampane has documented interactions with 1 drug class — the most serious being cns depressants (moderate) — and none of Ketorolac Tromethamine’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 Elecampane and Ketorolac Tromethamine May Share a Side Effect

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.

    “Topically, elecampane can cause allergic contact dermatitis, especially in individuals sensitive to the Asteraceae/Compositae family. Members of this family include ragweed, chrysanthemums, marigolds, daisies, and many other herbs.”

    Ketorolac Tromethamine

    Listed in the ADVERSE REACTIONS section of the FDA label for Ketorolac Tromethamine. Read the label on DailyMed ›

Reported for Elecampane but not commonly for Ketorolac Tromethamine: vomiting and diarrhea.

Effects for Ketorolac Tromethamine come from the ADVERSE REACTIONS section of its FDA label; effects for Elecampane come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 5,598 voluntary FDA FAERS reports for Ketorolac Tromethamine 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.

About Elecampane

What is Elecampane?

Elecampane
  • Cough and bronchitis
  • Asthma symptoms
  • Loosening mucus (expectorant)
  • Digestive upset
  • Intestinal worms (traditional)

Elecampane is a traditional herb used mainly for coughs and other respiratory complaints, and as a bitter for digestion. Modern human evidence is very limited, so it should be seen as a folk remedy rather than a proven treatment. Talk to your pharmacist or doctor before using it, and avoid it during pregnancy and breastfeeding.

Inula helenium · Asteraceae · Roots and rhizomes · Tea, tincture, dried root, capsules, lozenges, syrup

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

Elecampane: dosing

There is no standardized, well-established dose for elecampane. It is commonly taken as a tea made from the dried root, as a tincture, or in syrups and lozenges, with the amount varying by product and tradition.Because the strength of products varies and reliable dosing studies are lacking, the safest approach is to follow the directions on the product label and start with a small amount.

About Ketorolac

What Is Ketorolac Used For?

Brand names: Toradol, Acuvail

Ketorolac is used for short-term management of moderately severe acute pain — the kind that would otherwise require an opioid-level painkiller. It is most commonly used in a postoperative (after surgery) setting.

Treatment is always started with an injection (IV or IM), and oral tablets are only used as a follow-up if needed. The total treatment time — shots plus pills combined — must never exceed 5 days. It is not meant for minor aches or long-term pain conditions.

Most-Reported Side Effects for Ketorolac Tromethamine

From FAERS, the FDA’s public side-effect reporting system (5,598 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Is it safe to take Elecampane with Ketorolac Tromethamine?

Yes — our sources link each of them separately to one of the same effects. That is not an interaction: neither changes how your body handles the other.

How was the Elecampane and Ketorolac Tromethamine combination checked?
Interactions in our licensed database are recorded against drug classes. Ketorolac Tromethamine is filed under 6 classifications, and Elecampane has documented interactions with 1 drug class — none of Ketorolac Tromethamine'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 Elecampane interact with any other medications?
Yes. Elecampane has 248 documented drug interactions in our database — Ketorolac Tromethamine is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
