Drug & supplement interaction

Superoxide Dismutase (sod) + 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 Superoxide Dismutase (sod) 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.

Superoxide Dismutase (sod) 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 Superoxide Dismutase (sod) 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 Superoxide Dismutase (sod) 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.

Superoxide Dismutase (sod) safety at a glance

Superoxide Dismuta... overall Use caution Generally considered low-risk in short-term use, but long-term safety and effectiveness of supplements are not well established.
Pregnancy Avoid There is not enough reliable safety information, so it is best to avoid during pregnancy.
Breastfeeding Avoid Safety while breastfeeding is unknown, so avoiding it is the safer choice.

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

What to actually watch for

No Interaction Found — But Data Suggests Superoxide Dismutase (sod) and Cefaclor May Share a Side Effect

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. One of them is worth acting on rather than waiting out — marked below.

  • A severe allergic reaction Worth acting on Additional detail

    Superoxide Dismutase (sod)

    “Orally and parenterally, superoxide dismutase seems to be well tolerated.

    Most Common Adverse Effects:

    Parenterally: Pain and injection site reactions.

    Serious Adverse Effects (Rare):

    Listed in the ADVERSE REACTIONS section of the FDA label for Cefaclor. Read the label on DailyMed ›

Effects for Cefaclor come from the ADVERSE REACTIONS section of its FDA label; effects for Superoxide Dismutase (sod) come from the Natural Medicines adverse-effect record, quoted above. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

How to take them

Some Cefaclor Products Have a Food Rule — Superoxide Dismutase (sod) Should Not Break It

At least one FDA label for a product containing Cefaclor says to take it with food. If you take Superoxide Dismutase (sod) 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.

Overlapping uses

What Cefaclor Is Prescribed For, and What Superoxide Dismutase (sod) Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Cefaclor is a prescription medicine with approved uses on its FDA label. Superoxide Dismutase (sod) is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Cefaclor is prescribed for: 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.

Superoxide Dismutase (sod) has been studied for:

  • Pneumonia studied, not established Superoxide Dismutase (sod) has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Superoxide Dismutase (sod) for pneumonia

    It is unclear if intravenous superoxide dismutase is beneficial in patients with pneumonia.

Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Cefaclor on your own; if you are taking Superoxide Dismutase (sod) for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

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 Superoxide Dismutase (sod)

What is Superoxide Dismutase (sod)?

  • Antioxidant support
  • Anti-aging and skin health
  • Joint pain and arthritis
  • Exercise recovery and oxidative stress
  • General inflammation

Superoxide dismutase (SOD) is a natural antioxidant enzyme your body makes to help neutralize harmful free radicals. While it has clear biological importance, oral supplements may be broken down during digestion, and strong human evidence that taking SOD supplements improves health is limited. Talk to your pharmacist or doctor before using it, especially if you are pregnant or have a health condition.

Enzyme sourced from plants (such as cantaloupe melon), bovine liver, or made by microbes; also produced naturally in the body · Capsules, tablets, topical creams, injectable forms (used in some research settings)

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

Superoxide Dismutase (sod): dosing

There is no well-established standard dose for superoxide dismutase supplements. Doses vary widely between products and forms.The best advice is to follow the directions on the product label and not exceed the recommended amount.

Taking Superoxide Dismutase (sod) and Cefaclor Together: Common Questions

Is it safe to take Superoxide Dismutase (sod) with Cefaclor?
We do not list a known interaction between Superoxide Dismutase (sod) 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 Superoxide Dismutase (sod) and Cefaclor have any of the same side effects?
Yes — our sources link each of them separately to one 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 Superoxide Dismutase (sod) 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 Superoxide Dismutase (sod) 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.
Are Superoxide Dismutase (sod) and Cefaclor used for the same thing?
They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together. This page lists the shared uses and how strong the evidence is for Superoxide Dismutase (sod) in each. That is a conversation for your prescriber, especially if Cefaclor is being adjusted to a target.
Does Cefaclor interact with any supplements?
Yes. Cefaclor has documented interactions with 60 supplements in our database — Superoxide Dismutase (sod) is not one of them. The Cefaclor interaction page linked on this page lists every one, ranked by severity.
