No Known Interaction
The bottom line No known interaction

We found no known interaction between Krebiozen and Levetiracetam 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 Levetiracetam

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 Levetiracetam 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 Levetiracetam, 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.

From our pharmacist’s overview on the Levetiracetam page

“I would read this page carefully rather than casually. Levetiracetam (Keppra, Spritam) controls seizures, and both hazards on this list run through that fact.”

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 Levetiracetam

What Is Levetiracetam Used For?

Brand names: Keppra, Elepsia XR, Spritam

Levetiracetam is used to treat several types of seizures. It treats partial-onset seizures (seizures that start in one area of the brain) and is used as add-on therapy for myoclonic seizures (sudden, brief muscle jerks) in people with juvenile myoclonic epilepsy aged 12 and older, and for primary generalized tonic-clonic seizures (grand mal seizures) in people with idiopathic generalized epilepsy aged 6 and older.

Age eligibility varies by product. Keppra oral and Roweepra tablets treat partial-onset seizures in patients as young as 1 month. Spritam and levetiracetam tablets for oral suspension treat partial-onset seizures in patients 4 years and older weighing more than 20 kg. Extended-release products — including Elepsia XR, Keppra XR, and Levetiracetam ER — are approved only for partial-onset seizures in patients 12 years and older. Injectable forms are used intravenously when a patient temporarily cannot take oral medication.
