Prenatal Vitamins + Cefaclor
Cefaclor brand names: Ceclor CD, Ceclor.
We found no known interaction between Prenatal Vitamins 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.
Prenatal Vitamins 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 Prenatal Vitamins 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 Prenatal Vitamins 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.
Prenatal Vitamins safety at a glance
Pregnancy & breastfeeding ratings are from Natural Medicines (Therapeutic Research Center) — the full detail is in the Special populations card below. Safety guidance is general; always confirm with your pharmacist or doctor for your situation.
Prenatal Vitamins in Pregnancy & Breastfeeding
When used orally. Prenatal vitamins contain many different minerals, vitamins, and sometimes other dietary supplement ingredients. Each individual ingredient has a unique safety profile. Clinical studies evaluating prenatal vitamins show that prenatal vitamins are safe when used appropriately during pregnancy.
When used orally. Prenatal vitamins usually do not contain ingredients in amounts that exceed the tolerable upper intake level (UL). The UL is the highest level of nutrient intake that is unlikely to have a risk of adverse effects for most people, as determined by the Food and Nutrition Board and the National Academies of Science. Therefore, prenatal vitamins have apparent safety during lactation. However, high quality research assessing the safety of prenatal vitamins during lactation is lacking.

Some Cefaclor Products Have a Food Rule — Prenatal Vitamins Should Not Break It
At least one FDA label for a product containing Cefaclor says to take it with food. If you take Prenatal Vitamins 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 Prenatal Vitamins
What is Prenatal Vitamins?
- Nutritional support before and during pregnancy
- Preventing neural tube defects (folic acid)
- Supporting healthy fetal development
- Preventing iron-deficiency anemia in pregnancy
- Support during breastfeeding
Prenatal vitamins are multivitamin-mineral supplements designed to fill nutritional gaps before and during pregnancy and while breastfeeding, with folic acid and iron being especially important. They are widely recommended by doctors, but they do not replace a healthy diet, and you should choose a product and dose with guidance from your pharmacist or doctor.
Tablets, capsules, soft gels, chewables, gummies, liquids
An interaction check asks whether these two react with each other — it does not ask whether Prenatal Vitamins is a good idea for someone in your situation. Here is what our Prenatal Vitamins record says about it on its own.
Prenatal Vitamins: dosing
There is no single "correct" prenatal vitamin, since products differ in their ingredients and amounts. Most are taken once daily, but some require more than one tablet or a separate DHA softgel.

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 Prenatal Vitamins — it is a separate effect of the medicine, and it is a reason some people are advised to supplement rather than to avoid one:
