The bottom line No known interaction

We found no known interaction between Fig 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.

Fig 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 Fig 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.

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. Fig has documented interactions with 3 drug classes — the most serious being antidiabetes drugs (moderate), insulin (moderate) and photosensitizing drugs (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

What Fig Itself Has Been Linked To

This is not an interaction — nothing below involves Lanthanum Carbonate. It is the side-effect record for Fig on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Fig, this list is the first place to look. 2 entries are worth acting on rather than waiting out — marked below.

  • Anemia / A higher chance of infection Worth acting on Additional detail

    “Topically, fig leaf might cause photodermatitis. The leaf contains psoralens. Many cases of photodermatitis from fig leaf have been reported. In at least two cases, the burns were serious enough to require hospitalization. Severe anemia and sepsis developed in one patient,.”

We read the ADVERSE REACTIONS section of Lanthanum Carbonate’s FDA label too, and the two lists don’t meaningfully overlap — which is why no Lanthanum Carbonate column appears here.

How to take them

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

At least one FDA label for a product containing Lanthanum Carbonate says to take it with food. If you take Fig 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. See the Lanthanum Carbonate drug page ›

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 Fig

What is Fig?

  • Constipation and digestive health
  • Blood sugar support
  • Cough and sore throat
  • Skin conditions (topical sap)
  • Source of fiber and minerals

Fig (Ficus carica) is a common fruit that has long been used as a gentle food remedy for constipation, and its leaves are used traditionally for blood sugar and coughs. The fruit is a safe and nutritious food, but evidence for fig leaf supplements treating specific health conditions is limited. Talk to your pharmacist or doctor before using concentrated fig leaf products, especially if you have diabetes.

Ficus carica · Moraceae · Fruit, leaves, and latex (sap) · Fresh or dried fruit, leaf tea, leaf extract, syrup, capsules

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

Fig: dosing

There is no official standardized dose for fig as a medicine. As a food, people commonly eat a few dried or fresh figs for fiber and to help with constipation.For fig leaf teas, extracts, or capsules, no well-established medicinal dose exists. If you choose to use a product, follow the directions on the label and do not exceed the recommended amount.

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

Taking Fig and Lanthanum Carbonate Together: Common Questions

Is it safe to take Fig with Lanthanum Carbonate?
We do not list a known interaction between Fig 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.
Should I take Fig 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 Fig 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 Fig and Lanthanum Carbonate combination checked?
Interactions in our licensed database are recorded against drug classes. Lanthanum Carbonate is filed under 1 classification, and Fig 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 Fig interact with any other medications?
Yes. Fig has 410 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 — Fig is not one of them. The Lanthanum Carbonate interaction page linked on this page lists every one, ranked by severity.
