The bottom line No known interaction

We found no known interaction between Calcium D-glucarate and Allopurinol in our sources.

Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first.

Calcium D-glucarate and Allopurinol

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 Allopurinol and Calcium D-glucarate 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 Allopurinol

Interactions in our licensed database are recorded against drug classes, not just single drug names. Allopurinol is filed under 5 classifications — including antigout drugs, nephrotoxic drugs, hepatotoxic drugs. Calcium D-glucarate has documented interactions with 3 drug classes — the most serious being alcohol (ethanol) (moderate), glucuronidated drugs (moderate) and kanamycin (minor) — and none of Allopurinol’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.

From our pharmacist’s overview on the Allopurinol page

“Allopurinol (Zyloprim) prevents gout attacks by lowering uric acid, and I would give this list real weight, because 5 of the 60 supplements and herbs on file carry a major rating. The largest cluster, 38 ingredients, is products that can stress the liver on their own, and regular beer or wine sits in that major group, since alcohol on…”

About Calcium D-glucarate

What is Calcium D-glucarate?

Calcium D-glucarate
  • Detoxification support
  • Hormone balance
  • Estrogen metabolism
  • Liver support
  • General wellness

Calcium D-glucarate is a supplement form of a natural compound found in fruits and vegetables that is promoted for 'detoxification' and helping the body clear excess hormones. Human evidence for these benefits is very limited, and most research comes from laboratory or animal studies. Talk to your pharmacist or doctor before using it, especially if you have a hormone-related condition.

Not applicable (a calcium salt of D-glucaric acid) · Tablets, capsules

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

Calcium D-glucarate: dosing

There is no official or standardized dose for calcium D-glucarate, and the best dose for any health goal has not been established in humans.

About Allopurinol

What Is Allopurinol Used For?

Brand names: Zyloprim, Caplenal, Cosuric, Rimapurinol, Zyloric

Allopurinol tablets (including Zyloprim) are used in adults to treat the signs and symptoms of gout — including gout attacks, tophi (uric acid deposits), joint damage, and kidney problems caused by uric acid. Allopurinol tablets are also used in adults to reduce recurrent calcium oxalate kidney stones when uric acid in the urine is too high, even after lifestyle changes.

For adults and children with leukemia, lymphoma, or solid tumor cancers, allopurinol is used to control uric acid levels that rise during cancer treatment. The injectable forms — Allopurinol sodium for injection and Aloprim — are specifically for patients who cannot take medicine by mouth and are given intravenously (through a vein) in a hospital or clinical setting. Note: allopurinol tablets are not recommended for people who have high uric acid levels but no symptoms.
