Homotaurine + Cefaclor
Cefaclor brand names: Ceclor CD, Ceclor.
We found no known interaction between Homotaurine 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.
Homotaurine 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 Homotaurine 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 Homotaurine at all — not against Cefaclor, 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.
Homotaurine safety at a glance
Safety guidance is general; always confirm with your pharmacist or doctor for your situation.
Some Cefaclor Products Have a Food Rule — Homotaurine Should Not Break It
At least one FDA label for a product containing Cefaclor says to take it with food. If you take Homotaurine 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 Homotaurine 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 Homotaurine
What is Homotaurine?
- Memory support
- Brain and cognitive health
- Alzheimer's disease (investigational)
- General neuroprotection
Homotaurine (also called tramiprosate) is a small amino acid-like molecule studied mainly for slowing memory loss and Alzheimer's disease. Large clinical trials did not clearly prove it works, and it is now sold as a dietary supplement rather than an approved drug. Talk to your pharmacist or doctor before using it, especially if you have a medical condition.
Synthesized compound (also found naturally in some seaweeds) · Capsules, tablets
An interaction check asks whether these two react with each other — it does not ask whether Homotaurine is a good idea for someone in your situation. Here is what our Homotaurine record says about it on its own.
Homotaurine: dosing
There is no officially established supplement dose for homotaurine. Doses used in research were chosen for studying Alzheimer's disease and may not match what is sold in stores.If you choose to use a homotaurine product, follow the directions on the label and do not exceed the recommended amount.

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.

Cefaclor Is Linked to Lower Levels of 7 Nutrients
Natural Medicines records Cefaclor as a medicine that can lower these. This is not an interaction with Homotaurine — it is a separate effect of the medicine, and it is a reason some people are advised to supplement rather than to avoid one:
