Drug & supplement interaction

Fermented Wheat Germ Extract + Cefaclor

Cefaclor brand names: Ceclor CD, Ceclor.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Oct 4, 2026
The bottom line No known interaction

We found no known interaction between Fermented Wheat Germ Extract and Cefaclor 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. Additionally, although there is no interaction, the label for Cefaclor states a food rule worth keeping to, and the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

Fermented Wheat Germ Extract and Cefaclor

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 Cefaclor and Fermented Wheat Germ Extract 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.

Fermented Wheat Germ Extract safety at a glance

Fermented Wheat Ge... overall Use caution Generally tolerated in short-term studies, but long-term safety is not well established and people with cancer should clear it with their care team.
Pregnancy Avoid There is not enough safety data, so it is best avoided during pregnancy.
Breastfeeding Avoid Safety has not been studied, so avoid while breastfeeding.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Cefaclor

Interactions in our licensed database are recorded against drug classes, not just single drug names. Cefaclor is filed under 6 classifications — including organic anion transporter 3 (oat3) substrates, organic anion transporter 1 (oat1) substrates, antibiotic drugs. Fermented Wheat Germ Extract has documented interactions with 2 drug classes — the most serious being immunosuppressants (moderate) and serotonergic drugs (moderate) — and none of Cefaclor’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.

What to actually watch for

No Interaction Found — But Data Suggests Fermented Wheat Germ Extract and Cefaclor May Share Several of the Same Side Effects

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do.

  • Bloating or gas / Constipation / Vomiting Additional detail

    “Orally, fermented wheat germ extract may cause diarrhea, nausea, flatulence, satiation, soft stools, and constipation. In one clinical study, diarrhea and nausea with or without vomiting were reported in 6% and 3% of patients, respectively.”

How to take them

Some Cefaclor Products Have a Food Rule — Fermented Wheat Germ Extract Should Not Break It

At least one FDA label for a product containing Cefaclor says to take it with food. If you take Fermented Wheat Germ Extract on an empty stomach out of habit, keep them separate — and take Cefaclor with a meal where the label says to.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Cefaclor products can carry different directions, and extended-release forms often differ from immediate-release ones. The label we read is quoted below — check the directions on your own box or bottle, or ask your pharmacist, for how to take the exact product you were given.

DOSAGE AND ADMINISTRATION The absorption of cefaclor extended-release tablets is enhanced when it is administered with food.

From the Dosage and Administration section of the FDA label we read for Cefaclor — where that label names a specific product, the instruction is that product's. Read the label on DailyMed ›

A food rule is not an interaction — it is about how much of the medicine you absorb. The directions that came with your own product, and your pharmacist, outrank anything on this page.

See Every Supplement That Interacts With Cefaclor

This page covers Fermented Wheat Germ Extract only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Cefaclor page lists 60 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Asarabacca (major), Siberian Cocklebur (major), African Wild Potato (moderate) and Aristolochia (moderate).

By severity: 3 major · 46 moderate · 11 minor.

From our pharmacist’s overview on the Cefaclor page

“The entries worth understanding before any others on this cefaclor (Ceclor) page are the kidney risks and charcoal. Cefaclor is a cephalosporin antibiotic, typically a short course for ear, sinus, throat, or skin infections, and two herbs here, Siberian cocklebur and asarabacca, can damage the kidneys on their own, so pairing either wi…”

About Fermented Wheat Germ Extract

What is Fermented Wheat Germ Extract?

  • Cancer supportive care (as a complementary product)
  • Immune support
  • General wellness during cancer treatment
  • Antioxidant support
  • Fatigue during illness

Fermented wheat germ extract is a supplement made by fermenting wheat germ with yeast, and it is most often marketed for people going through cancer treatment. While some early research and a few small studies are interesting, the overall evidence is limited and far from conclusive, so it should never replace standard medical care. Talk with your oncologist or pharmacist before using it, since it is a supplement and not an approved treatment.

Triticum aestivum · Poaceae · Wheat germ (fermented with baker's yeast, Saccharomyces cerevisiae) · Powder (to mix in water or juice), capsules, tablets

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

Fermented Wheat Germ Extract: dosing

There is no official, standardized dose for fermented wheat germ extract that applies to everyone. Do not assume that taking more will work better, and do not use it as a replacement for prescribed therapy.

About Cefaclor

What Is Cefaclor Used For?

Brand names: Ceclor CD, Ceclor

Cefaclor treats a range of bacterial infections. The capsule and oral suspension forms are used for ear infections (otitis media), lower respiratory tract infections including pneumonia, strep throat and tonsillitis, urinary tract infections (including kidney infections and bladder infections), and skin and skin structure infections.

The extended-release tablet form of Cefaclor is approved for a narrower set of uses: acute bacterial flare-ups of chronic bronchitis, strep throat and tonsillitis, and uncomplicated skin infections. Not all infections approved for the capsule or suspension are approved for the extended-release tablet — your prescriber will choose the right form for your infection.

Most-Reported Side Effects for Cefaclor

From FAERS, the FDA’s public side-effect reporting system (1,535 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Drug hypersensitivity 252 reports
Nausea 159 reports
Vomiting 159 reports

Taking Fermented Wheat Germ Extract and Cefaclor Together: Common Questions

Is it safe to take Fermented Wheat Germ Extract with Cefaclor?
We do not list a known interaction between Fermented Wheat Germ Extract and Cefaclor. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Do Fermented Wheat Germ Extract and Cefaclor have any of the same side effects?
Yes — our sources link each of them separately to 5 of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.
Should I take Fermented Wheat Germ Extract and Cefaclor at the same time of day?
At least one FDA label for a product containing Cefaclor says to take it with food. If you take Fermented Wheat Germ Extract on an empty stomach out of habit, keep them separate and take Cefaclor with a meal where the label says to. Food instructions belong to the product rather than the ingredient — two Cefaclor products can differ — so check the directions on your own box. This is about absorption, not an interaction.
How was the Fermented Wheat Germ Extract and Cefaclor combination checked?
Interactions in our licensed database are recorded against drug classes. Cefaclor is filed under 6 classifications, and Fermented Wheat Germ Extract has documented interactions with 2 drug classes — none of Cefaclor's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
Does Fermented Wheat Germ Extract interact with any other medications?
Yes. Fermented Wheat Germ Extract has 303 documented drug interactions in our database — Cefaclor is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Cefaclor interact with any supplements?
Yes. Cefaclor has documented interactions with 60 supplements in our database — Fermented Wheat Germ Extract is not one of them. The Cefaclor interaction page linked on this page lists every one, ranked by severity.
