The bottom line No known interaction

Heather 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 Heather 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.

Worth understanding: our licensed dataset holds no drug-interaction record for Heather at all — not against Ketorolac Tromethamine, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

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.

What Ketorolac Tromethamine’s Own FDA Label Lists

This is not an interaction — none of it involves Heather. These are the most notable effects listed in the ADVERSE REACTIONS section of Ketorolac Tromethamine’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both. 8 of them are worth acting on rather than waiting out — marked below.

  • Bleeding in the gut Worth acting on
  • High potassium Worth acting on
  • A slow heartbeat Worth acting on
  • Heart failure Worth acting on
  • Kidney problems Worth acting on

  • Liver problems Worth acting on

Showing the 10 most notable of 13 label-listed effects — ranked by how unusual each one is across medicines generally, with serious effects weighted up.

From the ADVERSE REACTIONS section of the FDA label for Ketorolac Tromethamine. Read the label on DailyMed › 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. Heather’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Heather side to compare — that is a limit of the record, not a statement that Heather has no side effects.

About Heather

What is Heather?

  • Urinary tract complaints
  • Mild fluid retention
  • Joint and rheumatic discomfort
  • Sleep and relaxation
  • Skin and wound care (topical)

Heather (Calluna vulgaris) is a traditional European herb used mainly as a tea for urinary and minor inflammatory complaints, but high-quality human studies are lacking. It is generally considered gentle when used as a tea, though its effectiveness is largely unproven, so check with a pharmacist or doctor before relying on it.

Calluna vulgaris · Ericaceae · Flowering tops and aerial parts · Tea (dried flowers), tincture, liquid extract, capsules

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

Heather: dosing

There is no established standardized dose for heather. Traditional use is mostly as a tea made from the dried flowering tops, but exact amounts vary widely between products and sources.The safest approach is to follow the directions on the product label and not exceed them.

Most-Reported Side Effects for Ketorolac Tromethamine
