Androstenedione + Lanthanum Carbonate

Lanthanum Carbonate brand name: Fosrenol.

No Known Interaction
The bottom line No known interaction

We found no known interaction between Androstenedione 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.

Androstenedione 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 Androstenedione 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. Androstenedione has documented interactions with 1 drug class — the most serious being estrogens (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 Androstenedione Itself Has Been Linked To

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

  • Low mood Worth acting on Additional detail

    “There is some concern that androstenedione might cause or worsen depression in women. Some women with severe major depression seem to have increased endogenous androstenedione concentrations; however, it is not known if supplements can actually cause this adverse effect.”

  • A change in sex drive / Breast tenderness / Erection problems Additional detail

    “Orally, androstenedione possibly alters levels of estrogen and testosterone in men. Theoretically, this might cause decreased spermatogenesis, gynecomastia, testicular atrophy, and prostate hypertrophy. There is one case report of two episodes of priapism associated with androstenedione use in a 30-year-old man.”

Everything above comes from the Natural Medicines adverse-effect record for Androstenedione — expand a row for the licensed statement it rests on. 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 — Androstenedione Should Not Break It

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

What is Androstenedione?

Androstenedione
  • Muscle building
  • Athletic performance
  • Boosting testosterone
  • Anti-aging
  • Increasing libido

Androstenedione is a prohormone that the body can convert into testosterone and estrogen, but studies have not shown that taking it reliably builds muscle or improves athletic performance. It carries real risks, is a controlled substance in the United States, and is banned in nearly all sports, so most people should avoid it.

Not a plant; a hormone precursor made synthetically or in the body · Capsules, tablets, sublingual sprays, powders (where legally available)

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

Androstenedione: dosing

There is no established safe or effective dose for androstenedione. Past products varied widely, and because it is now a controlled substance, it is not appropriate to recommend any amount.If you encounter a product containing it, do not assume the label dose is safe or accurate. The safest choice is to avoid it.

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

Taking Androstenedione and Lanthanum Carbonate Together: Common Questions

Is it safe to take Androstenedione with Lanthanum Carbonate?
We do not list a known interaction between Androstenedione 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 Androstenedione 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 Androstenedione 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 Androstenedione and Lanthanum Carbonate combination checked?
Interactions in our licensed database are recorded against drug classes. Lanthanum Carbonate is filed under 1 classification, and Androstenedione has documented interactions with 1 drug class — 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 Androstenedione interact with any other medications?
Yes. Androstenedione has 41 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 — Androstenedione is not one of them. The Lanthanum Carbonate interaction page linked on this page lists every one, ranked by severity.
