Drug & supplement interaction

Padang Cassia + Cefaclor

Cefaclor brand names: Ceclor CD, Ceclor.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between Padang Cassia 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.

Interaction report

Padang Cassia 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 Padang Cassia 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.

Padang Cassia safety at a glance

Padang Cassia overall Use caution Generally safe as a food spice, but cassia cinnamons contain coumarin that may harm the liver in large or long-term supplement doses.
Pregnancy Use caution Food amounts are likely fine, but avoid concentrated supplement doses during pregnancy without medical advice.
Breastfeeding Use caution Food amounts are likely fine, but there is little safety data on supplement-level doses 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. Padang Cassia has documented interactions with 3 drug classes — the most serious being antidiabetes drugs (moderate), cytochrome p450 3a4 (cyp3a4) substrates (moderate) and hepatotoxic 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 Padang Cassia 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.

  • Tremor or shakiness / Dizziness / Headache Additional detail

    Padang Cassia

    “Orally, Padang cassia appears to be well tolerated. No adverse effects have been reported in clinical trials when Padang cassia is used alone. When Padang cassia extract is used with banaba leaf extract in a specific combination product (Inlacin, Dexa Medica), adverse effects reported in clinical trials have included dizziness, headache, tremor, palpitations, weakness, diaphoresis, and stomach upset.”

How to take them

Some Cefaclor Products Have a Food Rule — Padang Cassia Should Not Break It

At least one FDA label for a product containing Cefaclor says to take it with food. If you take Padang Cassia 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.

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 Padang Cassia

What is Padang Cassia?

  • Adding flavor to food
  • Digestive upset
  • Blood sugar support
  • Antimicrobial purposes
  • Antioxidant support

Padang Cassia is a type of cinnamon (Indonesian or Korintje cinnamon) grown mainly in Indonesia and used widely as a kitchen spice. As a supplement, evidence for health benefits like blood sugar control is limited and mixed, and like other cassia cinnamons it naturally contains coumarin, which can be harmful to the liver in large amounts. Use food amounts freely, but talk to a pharmacist or doctor before taking concentrated cinnamon supplements.

Cinnamomum burmannii · Lauraceae · Inner bark (and bark-derived essential oil) · Ground spice, dried bark sticks (quills), capsules, powder, extract, essential oil, tea

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

Padang Cassia: dosing

There is no official, standardized dose of Padang Cassia for any health condition. Amounts used in studies vary widely and are not specific to this species.If you choose to use a cinnamon supplement, follow the directions on the product label and do not exceed the recommended amount. Because cassia cinnamons are higher in coumarin, it is wise to keep concentrated supplement doses low and to avoid taking them every day for long periods.Using Padang Cassia as a normal cooking spice is a low-risk way to enjoy it.

About Cefaclor

What Is Cefaclor Used For?

Brand names: Ceclor CD, Ceclor

Cefaclor treats a range of bacterial infections. Cefaclor capsules and oral suspension 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.

Cefaclor extended-release tablets are approved for a narrower set of uses in adults: acute bacterial flare-ups of chronic bronchitis, strep throat and tonsillitis, and uncomplicated skin and skin structure infections. Not all formulations are approved for the same conditions, so the form matters.

Taking Padang Cassia and Cefaclor Together: Common Questions

Is it safe to take Padang Cassia with Cefaclor?
We do not list a known interaction between Padang Cassia 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 Padang Cassia 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 Padang Cassia 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 Padang Cassia 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 Padang Cassia and Cefaclor combination checked?
Interactions in our licensed database are recorded against drug classes. Cefaclor is filed under 6 classifications, and Padang Cassia has documented interactions with 3 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 Padang Cassia interact with any other medications?
Yes. Padang Cassia has 934 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 — Padang Cassia is not one of them. The Cefaclor interaction page linked on this page lists every one, ranked by severity.
