The bottom line No known interaction

We found no known interaction between Diatomaceous Earth and Interferon Beta-1a 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.

Interaction report

Diatomaceous Earth and Interferon Beta-1a

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 Interferon Beta-1a and Diatomaceous Earth 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 Diatomaceous Earth at all — not against Interferon Beta-1a, 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.

See Every Supplement That Interacts With Interferon Beta-1a

This page covers Diatomaceous Earth only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Interferon Beta-1a page lists 57 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Beer (major), Siberian Cocklebur (major), Wine (major), Alfalfa (moderate) and Angelica Archangelica (moderate).

By severity: 3 major · 53 moderate · 1 minor.

From our pharmacist’s overview on the Interferon Beta-1a page

“Siberian cocklebur, an herb tied to documented cases of liver failure, is the first name to know for anyone injecting interferon beta-1a (Rebif, Avonex) for multiple sclerosis. Interferon beta-1a can strain the liver on its own, which is why prescribers order routine liver blood tests, and 38 of the 57 supplements on file carry that sa…”

About Diatomaceous Earth

What is Diatomaceous Earth?

  • Digestive cleansing or 'detox'
  • Intestinal parasite support
  • Skin, hair, and nail health (silica)
  • Cholesterol support
  • Toxin or heavy metal binding

Diatomaceous earth is a fine powder made from the fossilized shells of tiny algae called diatoms. Only food-grade diatomaceous earth should ever be swallowed, and human evidence for its health claims (detox, parasites, cholesterol) is very limited. Never inhale the dust, and talk to a pharmacist or doctor before taking it.

Fossilized remains of diatoms (a type of algae) · Food-grade powder, capsules, mixed into water or smoothies

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

Diatomaceous Earth: dosing

There is no official, standardized dose of diatomaceous earth, and it is not approved as a medicine. Amounts vary widely between products and brands.If you choose to use it, follow the directions on a clearly labeled food-grade product, start low, and drink plenty of water.

About Interferon Beta-1a Intramuscular Injection

What Is Interferon Beta-1a Intramuscular Injection Used For?

Brand names: Rebif, Avonex

  • Interferon beta-1a intramuscular injection is used to treat adults with various forms of multiple sclerosis (MS; a disease in which the nerves do not function properly and people may experience weakness, numbness, loss of muscle coordination, and problems with vision, speech, and bladder control) including:

    • clinically isolated syndrome (CIS; nerve symptom episodes that last at least 24 hours),

    • relapsing-remitting forms (course of disease where symptoms flare up from time to time), or

    • secondary progressive forms (course of disease where relapses occur more often).

  • Interferon beta-1a is in a class of medications called immunomodulators. It works by decreasing inflammation and preventing nerve damage that may cause symptoms of multiple sclerosis.

Most-Reported Side Effects for Interferon Beta-1a

From FAERS, the FDA’s public side-effect reporting system (192,069 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.
