Drug & supplement interaction

English Ivy + Lanthanum Carbonate

Lanthanum Carbonate brand name: Fosrenol.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 27, 2026
The bottom line No known interaction

We found no known interaction between English Ivy 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, and 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

English Ivy 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 English Ivy 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.

English Ivy safety at a glance

English Ivy overall Use caution Standardized leaf-extract products are generally well tolerated, but the raw plant is toxic and can cause poisoning or skin reactions.
Pregnancy Avoid There is not enough reliable safety information, so it is best avoided during pregnancy.
Breastfeeding Avoid Safety while breastfeeding is unknown, so avoid use unless directed by your doctor.

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

How we checked

Why No Interaction Is Listed for Lanthanum Carbonate

Interactions in our licensed database are recorded against drug classes, not just single drug names. Lanthanum Carbonate is filed under a single classification — oral drugs. English Ivy has documented interactions with 3 drug classes — the most serious being cytochrome p450 2c19 (cyp2c19) substrates (moderate), cytochrome p450 2c8 (cyp2c8) substrates (moderate) and cytochrome p450 2d6 (cyp2d6) substrates (moderate) — and none of Lanthanum Carbonate’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 English Ivy and Lanthanum Carbonate 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.

  • Stomach pain / Diarrhea / Vomiting / Nausea Additional detail

    English Ivy

    “Orally, English ivy can cause abdominal pain, diarrhea, nausea, and vomiting. The saponin constituents of English ivy can produce an acrid and/or bitter taste (7).”

    Lanthanum Carbonate

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

Reported for English Ivy but not commonly for Lanthanum Carbonate: an allergic reaction, a change in taste and a skin rash.

Effects for Lanthanum Carbonate come from the ADVERSE REACTIONS section of its FDA label; effects for English Ivy come from the Natural Medicines adverse-effect record, quoted above. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

How to take them

Some Lanthanum Carbonate Products Have a Food Rule — English Ivy Should Not Break It

At least one FDA label for a product containing Lanthanum Carbonate says to take it with food. If you take English Ivy 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 English Ivy

What is English Ivy?

English Ivy
  • Cough and chest congestion
  • Bronchitis
  • Asthma symptoms
  • Sore throat
  • Skin irritation

English ivy leaf extract is most commonly used in cough and cold syrups to help loosen mucus and ease coughing, and it is a popular ingredient in many European herbal products. Some research suggests it may help with certain coughs, but the evidence is still limited and mixed. The raw plant is poisonous if eaten and can irritate skin, so only use properly prepared commercial products and check with your pharmacist first.

Hedera helix · Araliaceae · Leaves (dried leaf extract) · Syrups, cough drops, oral drops, capsules, tea, topical preparations

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

English Ivy: dosing

There is no single official standardized dose of English ivy for everyone. The right amount depends on the specific product, its strength, and the form (syrup, drops, or capsules).The best approach is to follow the directions on the product label and use only products made for human use.

About Lanthanum

What Is Lanthanum Used For?

Brand name: Fosrenol

Lanthanum carbonate — available as lanthanum carbonate chewable tablets and as Fosrenol in both chewable tablet and oral powder forms — is used to lower elevated serum phosphate (too much phosphate in the blood) in people with end-stage renal disease (ESRD), the most advanced stage of chronic kidney disease.

Managing high phosphate in ESRD typically involves eating less phosphate-rich food, removing phosphate through dialysis, and using a phosphate binder like lanthanum carbonate to reduce how much phosphate is absorbed from meals.

Most-Reported Side Effects for Lanthanum Carbonate

From FAERS, the FDA’s public side-effect reporting system (0 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Nausea 493 reports
Vomiting 480 reports
Constipation 376 reports
Sepsis 368 reports
Abdominal pain 365 reports

Taking English Ivy and Lanthanum Carbonate Together: Common Questions

Is it safe to take English Ivy with Lanthanum Carbonate?
We do not list a known interaction between English Ivy and Lanthanum Carbonate. 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 English Ivy and Lanthanum Carbonate have any of the same side effects?
Yes — our sources link each of them separately to 4 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.
Should I take English Ivy and Lanthanum Carbonate at the same time of day?
At least one FDA label for a product containing Lanthanum Carbonate says to take it with food. If you take English Ivy on an empty stomach out of habit, keep them separate and take Lanthanum Carbonate with a meal where the label says to. Food instructions belong to the product rather than the ingredient — two Lanthanum Carbonate products can differ — so check the directions on your own box. This is about absorption, not an interaction.
How was the English Ivy and Lanthanum Carbonate combination checked?
Interactions in our licensed database are recorded against drug classes. Lanthanum Carbonate is filed under 1 classification, and English Ivy has documented interactions with 3 drug classes — none of Lanthanum Carbonate'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 English Ivy interact with any other medications?
Yes. English Ivy has 280 documented drug interactions in our database — Lanthanum Carbonate 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 Lanthanum Carbonate interact with any supplements?
Yes. Lanthanum Carbonate has documented interactions with 17 supplements in our database — English Ivy is not one of them. The Lanthanum Carbonate interaction page linked on this page lists every one, ranked by severity.
