Drug & supplement interaction

Aspartic Acid + Cefaclor

Cefaclor brand names: Ceclor CD, Ceclor.

No Known Interaction
The bottom line No known interaction

We found no known interaction between Aspartic Acid 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.

Aspartic Acid 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 Aspartic Acid 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 Aspartic Acid 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.

What to actually watch for

What Cefaclor’s Own FDA Label Lists

This is not an interaction — none of it involves Aspartic Acid. These are the most notable effects listed in the ADVERSE REACTIONS section of Cefaclor’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both. 10 of them are worth acting on rather than waiting out — marked below.

  • Pain or burning when passing urine Worth acting on
  • Heart failure Worth acting on
  • Fainting Worth acting on
  • Wheezing Worth acting on
  • Confusion Worth acting on
  • A severe skin reaction Worth acting on
  • Chest pain Worth acting on
  • A low platelet count Worth acting on
  • Kidney problems Worth acting on
  • Anemia Worth acting on

From the ADVERSE REACTIONS section of the FDA label for Cefaclor. Read the label on DailyMed › Aspartic Acid’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Aspartic Acid side to compare — that is a limit of the record, not a statement that Aspartic Acid has no side effects.

Special populations

Aspartic Acid in Pregnancy & Breastfeeding

Pregnancy And Lactation Likely Safe

When used orally in amounts found in foods.

Pregnancy And Lactation Possibly Unsafe

When aspartic acid is used orally. In rodents, aspartic acid given orally within a few days of birth caused neuronal necrosis in the hypothalamus. This adverse effect was not seen in nonhuman newborn primates and has not been assessed in humans. Until more data is available, the Institute of Medicine (IOM) and the Food and Nutrition Board advise that pregnant or breast-feeding women avoid the use of aspartic acid.

How to take them

Some Cefaclor Products Have a Food Rule — Aspartic Acid Should Not Break It

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

What is Aspartic Acid?

Aspartic Acid
  • Testosterone support
  • Athletic performance and muscle building
  • Energy and endurance
  • General amino acid supplementation

Aspartic acid is a common amino acid your body makes on its own and gets from protein-rich foods, so a true deficiency is rare. D-aspartic acid is heavily marketed for boosting testosterone and athletic performance, but the evidence is mixed and many studies show little or no lasting benefit. Talk with your pharmacist or doctor before using high-dose supplements.

Amino acid (made in the body and found in protein-rich foods) · Capsules, tablets, powders (D-aspartic acid and L-aspartic acid), found in protein supplements

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

Aspartic Acid: dosing

There is no official or standardized dose of aspartic acid for any health purpose. Doses used in studies of D-aspartic acid have varied, and the best amount (if any) is not established.Because dosing is uncertain, the safest approach is to follow the directions on the product label and not exceed them. More is not necessarily better, and very high doses may not help and could even work against you.

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.

Nausea 159 reports

Taking Aspartic Acid and Cefaclor Together: Common Questions

Should I take Aspartic Acid 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 Aspartic Acid 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.
Does Cefaclor interact with any supplements?
Yes. Cefaclor has documented interactions with 60 supplements in our database — Aspartic Acid is not one of them. The Cefaclor interaction page linked on this page lists every one, ranked by severity.
