Interaction report

Calcium D-glucarate and Rucaparib Camsylate

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 Rucaparib Camsylate 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 Rucaparib Camsylate

Interactions in our licensed database are recorded against drug classes, not just single drug names. Rucaparib Camsylate is filed under 3 classifications — cytochrome p450 2d6 (cyp2d6) substrates, p-glycoprotein substrates, oral 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 Rucaparib Camsylate’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.

These are the most notable effects listed in the ADVERSE REACTIONS section of Rucaparib Camsylate’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both. 10 of them are worth acting on rather than waiting out — marked below.

Blood clots Worth acting on
Heart failure Worth acting on
Low mood Worth acting on
A low platelet count Worth acting on
Kidney problems Worth acting on
Anemia Worth acting on
Shortness of breath Worth acting on
A low white blood cell count Worth acting on

From the ADVERSE REACTIONS section of the FDA label for Rucaparib Camsylate. Read the label on DailyMed › Calcium D-glucarate’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Calcium D-glucarate side to compare — that is a limit of the record, not a statement that Calcium D-glucarate has no side effects.

Overlapping uses

What Rucaparib Camsylate Is Prescribed For, and What Calcium D-glucarate Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Rucaparib Camsylate is a prescription medicine with approved uses on its FDA label. Calcium D-glucarate is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Rucaparib Camsylate is prescribed for: Rubraca (rucaparib) is used for two types of cancer in adults who carry a harmful BRCA gene mutation (either inherited or found in the tumor). First, it is used as maintenance treatment — meaning ongoing treatment to keep cancer from coming back — in people with recurrent epithelial ovarian cancer, fallopian tube cancer, or primary peritoneal cancer who responded (fully or partially) to platinum-based chemotherapy. Second, Rubraca treats metastatic castration-resistant prostate cancer (advanced prostate cancer that has stopped responding to hormone-lowering treatment) in adults who have already received androgen receptor-directed therapy. Patients must be tested with an FDA-approved companion diagnostic to confirm the BRCA mutation before starting Rubraca for prostate cancer.

Calcium D-glucarate has been studied for:

Prostate cancer studied, not established Calcium D-glucarate has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

Calcium D-glucarate for prostate cancer

Although there has been interest in using oral calcium D-glucarate for preventing prostate cancer, there is insufficient reliable information about the clinical effects of calcium D-glucarate for this purpose.

Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Rucaparib Camsylate on your own; if you are taking Calcium D-glucarate for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

About Calcium D-glucarate

What is 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.
