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

Fadogia Agrestis and Valrubicin

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 Valrubicin and Fadogia Agrestis 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 Fadogia Agrestis at all — not against Valrubicin, 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

What Valrubicin’s Own FDA Label Lists

This is not an interaction — none of it involves Fadogia Agrestis. These are the most notable effects listed in the ADVERSE REACTIONS section of Valrubicin’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. 6 of them are worth acting on rather than waiting out — marked below.

  • Pain or burning when passing urine Worth acting on
  • Trouble passing urine Worth acting on
  • High blood sugar Worth acting on
  • Chest pain Worth acting on
  • Anemia Worth acting on
  • A higher chance of infection Worth acting on
  • Loss of bladder control
  • Passing urine more often
  • Bloating or gas
  • Back pain

Showing the 10 most notable of 22 label-listed effects — ranked by how unusual each one is across medicines generally, with serious effects weighted up.

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

Everything else you take

See Every Supplement That Interacts With Valrubicin

This page covers Fadogia Agrestis only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Valrubicin page lists 24 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Acerola (moderate), Alpha-lipoic Acid (moderate), Coffee Charcoal (moderate) and European Mandrake (moderate).

By severity: 1 major · 14 moderate · 9 minor.

From our pharmacist’s overview on the Valrubicin page

“Activated charcoal is the supplement I would flag hardest for anyone receiving valrubicin (Valstar), a chemotherapy instilled directly into the bladder for cancer. It carries the only major rating among the 24 ingredients on this page, since charcoal can bind and clear many drugs from the body even when they are not swallowed.”

Where does our data come from?

About Fadogia Agrestis

What is Fadogia Agrestis?

  • Boosting testosterone
  • Improving libido and sexual function
  • Athletic performance and muscle building
  • Traditional African remedy for various ailments

Fadogia agrestis is a West African shrub marketed as a testosterone booster, but human evidence is essentially nonexistent and what we know comes mostly from a few small rat studies. Animal data raise real concerns about organ toxicity, so the safety of long-term use in people is unknown. Talk with your pharmacist or doctor before trying it, and avoid it if you are pregnant, breastfeeding, or have any underlying health conditions.

Fadogia agrestis · Rubiaceae · Stem (and sometimes leaves and roots) · Capsules, powders, and tinctures (often sold as a standardized extract)

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

Fadogia Agrestis: dosing

There is no established or proven safe dose of Fadogia agrestis for humans. The doses used in supplements are based on animal studies and manufacturer choices, not on human research.If you choose to use a product, follow the directions on the label and do not exceed them.

About Valrubicin Intravesical

What Is Valrubicin Intravesical Used For?

Brand name: Valstar

Valrubicin Intravesical Solution is used to treat BCG-refractory carcinoma in situ (CIS) of the urinary bladder — meaning bladder cancer that has not responded to BCG immunotherapy. It is given directly into the bladder (intravesically) rather than taken by mouth or injected into the bloodstream.

This treatment is specifically for patients whose cancer has not responded to BCG and for whom having the bladder surgically removed (cystectomy) right away would carry unacceptable health risks.

Most-Reported Side Effects for Valrubicin

From FAERS, the FDA’s public side-effect reporting system (177 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Underdose 26 reports
Bladder instillation procedure 24 reports
Urge incontinence 20 reports
Bladder spasm 13 reports
Urinary incontinence 11 reports
