The bottom line No known interaction

We found no known interaction between Greater Burnet and Lanthanum Carbonate 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 label for Lanthanum Carbonate states a food rule worth keeping to.

Greater Burnet and Lanthanum Carbonate

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 Lanthanum Carbonate 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 Lanthanum Carbonate, 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 to actually watch for

What Lanthanum Carbonate’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 Lanthanum Carbonate’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. One of them is worth acting on rather than waiting out — marked below.

  • A bowel blockage Worth acting on
  • Stomach upset
  • Constipation
  • Stomach pain
  • Diarrhea
  • Vomiting
  • Nausea

From the ADVERSE REACTIONS section of the FDA label for Lanthanum Carbonate. Read the label on DailyMed › 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.

How to take them

Some Lanthanum Carbonate Products Have a Food Rule — Greater Burnet Should Not Break It

At least one FDA label for a product containing Lanthanum Carbonate says to take it with food. If you take Greater Burnet on an empty stomach out of habit, keep them separate — and take Lanthanum Carbonate with a meal where the label says to.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Lanthanum Carbonate products can carry different directions, and extended-release forms often differ from immediate-release ones. The label we read is quoted below — check the directions on your own box or bottle, or ask your pharmacist, for how to take the exact product you were given.

Do not store FOSRENOL Oral Powder for future use once mixed with food.

From the Dosage and Administration section of the FDA label we read for Lanthanum Carbonate — where that label names a specific product, the instruction is that product's. Read the label on DailyMed ›

A food rule is not an interaction — it is about how much of the medicine you absorb. The directions that came with your own product, and your pharmacist, outrank anything on this page.

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.

About Lanthanum

What Is Lanthanum Used For?

Brand name: Fosrenol

Lanthanum is used to lower phosphate in the blood of people with end-stage renal disease (ESRD). Both Fosrenol and generic lanthanum carbonate chewable tablets carry this use.

Managing high phosphorus in ESRD usually involves three things: eating less phosphate, removing phosphate with dialysis, and using a phosphate binder to reduce how much phosphate the gut absorbs. Lanthanum is the binder part of that plan.
