Greater Burnet and Lorlatinib

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 Lorlatinib and Greater Burnet 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 Greater Burnet at all — not against Lorlatinib, 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 Lorlatinib’s Own FDA Label Lists

This is not an interaction — none of it involves Greater Burnet. These are the most notable effects listed in the ADVERSE REACTIONS section of Lorlatinib’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. 10 of them are worth acting on rather than waiting out — marked below.

  • Mania or an unusually elevated mood Worth acting on
  • Loss of vision Worth acting on
  • Low magnesium Worth acting on
  • Thoughts of self-harm Worth acting on
  • Muscle weakness Worth acting on
  • Memory problems Worth acting on
  • High potassium Worth acting on
  • Unsteadiness Worth acting on
  • A heart attack Worth acting on
  • Blood clots Worth acting on

Showing the 10 most notable of 48 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 Lorlatinib. Read the label on DailyMed › Where a percentage is shown, it is the share of 6,977 voluntary FDA FAERS reports for Lorlatinib that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Greater Burnet’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Greater Burnet side to compare — that is a limit of the record, not a statement that Greater Burnet has no side effects.

About Greater Burnet

What is Greater Burnet?

  • Diarrhea and digestive upset
  • Minor bleeding and wounds
  • Burns and skin irritation (topical)
  • Sore throat and mouth inflammation
  • Hemorrhoids

Greater Burnet (Sanguisorba officinalis) is a traditional herb whose tannin-rich root has long been used for diarrhea, minor bleeding, and skin problems. Modern human evidence for these uses is very limited, so it should not replace proven treatments. Talk with your pharmacist or doctor before using it, especially if you are pregnant, breastfeeding, or taking other medicines.

Sanguisorba officinalis · Rosaceae · Root and rhizome (sometimes the leaves and aerial parts) · Dried root, tea/decoction, tincture, powder, topical preparations

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

Greater Burnet: dosing

There is no well-established standardized dose for Greater Burnet. Traditional use varies widely depending on the form (tea, tincture, powder, or topical) and the part of the plant.Because reliable dosing studies are lacking, the safest approach is to follow the directions on the product label and not exceed the recommended amount. They can help you decide whether it is appropriate and what amount, if any, is reasonable.
