Drug & supplement interaction

Ackee + 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 Ackee 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.

Ackee 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 Ackee 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 Ackee 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

No Interaction Found — But Data Suggests Ackee 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 Additional detail

    Ackee

    “Chronic oral ingestion of canned ackee fruit has been associated with cholestatic liver disease. In a case report, chronic ackee consumption resulted in cholestatic jaundice in a 27-year-old male. The patient presented with symptoms of steatosis, jaundice, pruritis, diarrhea and abdominal pain. Toxic hypoglycemic syndrome (THS) associated with consumption of unripe ackee can ultimately result in liver damage.”

How to take them

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

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

What is Ackee?

Ackee
  • Food source (cooked ripe fruit)
  • Traditional digestive remedies
  • Folk treatment for fever
  • Traditional wound and skin care
  • Folk use for aches and pains

Ackee is best known as a food — the national fruit of Jamaica — but only the fully ripe, properly prepared aril is safe to eat. Unripe ackee and its seeds contain natural toxins that can cause severe, sometimes fatal poisoning, so there is no good evidence supporting it as a medicinal supplement. If you eat ackee, use only ripe, commercially canned or properly prepared fruit.

Blighia sapida · Sapindaceae · Ripe fruit (aril); seeds, leaves, and bark used traditionally · Fresh ripe fruit, canned fruit, traditional decoctions of leaves or bark

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

Ackee: dosing

There is no established medicinal dose for ackee, and it is not recommended as a supplement. When eaten as a food, only the fully ripe, properly cleaned and cooked aril should be consumed, and seeds should never be eaten.Because there is no standardized or proven medicinal dose, and because of the real risk of poisoning, do not use ackee as a remedy.

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.

Taking Ackee and Lanthanum Carbonate Together: Common Questions

Is it safe to take Ackee with Lanthanum Carbonate?
We do not list a known interaction between Ackee 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 Ackee and Lanthanum Carbonate have any of the same side effects?
Yes — our sources link each of them separately to 3 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 Ackee 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 Ackee 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.
Does Lanthanum Carbonate interact with any supplements?
Yes. Lanthanum Carbonate has documented interactions with 17 supplements in our database — Ackee is not one of them. The Lanthanum Carbonate interaction page linked on this page lists every one, ranked by severity.
