The bottom line No known interaction

We found no known interaction between Krebiozen and Diclofenac 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.

Krebiozen and Diclofenac

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 Diclofenac and Krebiozen 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 Krebiozen at all — not against Diclofenac, 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 Diclofenac’s Own FDA Label Lists

This is not an interaction — none of it involves Krebiozen. These are the most notable effects listed in the ADVERSE REACTIONS section of Diclofenac’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.

  • Loss of vision Worth acting on
  • Hearing loss Worth acting on
  • Bleeding in the gut Worth acting on
  • High potassium Worth acting on
  • Unsteadiness Worth acting on
  • Low blood sugar Worth acting on
  • A heart attack Worth acting on
  • Pancreatitis Worth acting on
  • Yellowing of the skin or eyes Worth acting on
  • Heart failure Worth acting on

Showing the 10 most notable of 73 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 Diclofenac. Read the label on DailyMed › Where a percentage is shown, it is the share of 164,880 voluntary FDA FAERS reports for Diclofenac that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Krebiozen’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Krebiozen side to compare — that is a limit of the record, not a statement that Krebiozen has no side effects.

See Every Supplement That Interacts With Diclofenac

This page covers Krebiozen only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Diclofenac page lists 306 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Asarabacca (major), Beer (major), Danshen (major) and Piracetam (major).

By severity: 7 major · 265 moderate · 34 minor.

From our pharmacist’s overview on the Diclofenac page

“Diclofenac (Zorvolex) is an NSAID pain reliever that already stresses the stomach lining and kidneys on its own, so treat this list as a real safety issue, not fine print. Two thirds of the 306 supplements on file can thin the blood or slow clotting, and stacked on an NSAID that raises the odds of stomach bleeding.”

About Krebiozen

What is Krebiozen?

  • Promoted as a cancer treatment (unproven)

Krebiozen was a so-called "cancer cure" promoted in the 1950s and 1960s that was never proven to work and was discredited by U.S. government investigations. It is not a dietary supplement or herb, it is not available legally, and you should not seek it out as a treatment for any condition.

Originally claimed to be derived from horse blood serum (not a plant) · Historically sold as an injectable liquid

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

Krebiozen: dosing

There is no legitimate, established dose for Krebiozen because it is not an approved or recommended treatment. It is not a product you should obtain or use.If you come across something being sold today under the name Krebiozen or marketed as a similar "secret" cancer cure, do not use it.

About Diclofenac

What Is Diclofenac Used For?

Brand name: Zorvolex

Diclofenac sodium topical gel is used to treat actinic keratoses (AK) — rough, scaly skin patches that form after years of sun exposure. These patches are considered precancerous, meaning they can develop into skin cancer if left untreated.

This is a topical gel, meaning it is applied directly to the skin over the affected area rather than taken by mouth. It belongs to the NSAID (nonsteroidal anti-inflammatory drug) family.

Most-Reported Side Effects for Diclofenac

From FAERS, the FDA’s public side-effect reporting system (164,880 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Fatigue 14,336 reports
Arthralgia 11,682 reports
Rash 11,262 reports
