What cefaclor pills look like
Imprint codes, colour and shape from the FDA’s labelling data. Match the imprint on your pill — or search any imprint.
Can you crush or split cefaclor?
The cefaclor labels that address it permit crushing or splitting in the terms they state — quoted per product, because the instruction belongs to the form.
What each cefaclor label says about crushing, splitting and chewingHow long cefaclor keeps
The date on a sealed pack is not the only one: some cefaclor labels start a second clock once the product is opened or mixed, as short as 14 days.

Full LactMed record for cefaclor: levels in milk, effects in breastfed infants, and the drugs it would consider insteadCefaclor is no longer marketed in the United States. Limited information indicates that maternal cefaclor produces low levels in milk which are not expected to cause adverse effects in breastfed infants. Occasionally disruption of the infant's gastrointestinal flora, resulting in diarrhea or thrush have been reported with cephalosporins, but these effects have not been adequately evaluated. Cefaclor is acceptable in nursing mothers.

What people report to the FDA about cefaclor
The FDA Adverse Event Reporting System (FAERS) collects reports from patients and clinicians. It holds 1,646 reports naming cefaclor, and the FDA flagged 87% of those reports as serious. The effects reported most often — leaving out reports about overdose, misuse or the condition being treated, which dominate the raw list for common medicines:
- drug hypersensitivity253 reports
- nausea166 reports
- vomiting166 reports
- fatigue139 reports
- pyrexia128 reports
- dizziness114 reports
- diarrhoea108 reports
- infection107 reports
Read these as a signal, not a rate. A report does not mean cefaclor caused the effect — anyone can file one, and many describe people taking several medicines for several conditions. Crucially there is no denominator: FAERS does not record how many people took the drug, so these counts cannot be turned into “X% of patients” — a bigger number often just means a more widely used or more talked-about drug. Duplicates exist, and publicity drives reporting. For what is actually established, read the FDA label.

Frequently asked questions
Can you take cefaclor with other medicines?
It depends on the medicine. We check it against the FDA labels rather than guessing: our interaction checker searches each drug's own label for the other and quotes what it says, naming the section it came from. Run cefaclor against whatever else you take — and remember that a label not naming a drug is not the same as that combination being safe.
What brand names is cefaclor sold under?
We track 2 cefaclor-containing products in the U.S.: Cefaclor and Ceclor Cd. They are the same active ingredient; they differ in form, manufacturer, price and FDA recall record.
What forms does cefaclor come in?
Across the brands we track, cefaclor is currently marketed as capsule, suspension and tablet, extended release, per the FDA's National Drug Code Directory. Each form is dosed differently — follow the label for the exact product you were prescribed.
Is there a generic cefaclor?
Yes. Our catalog lists 1 generic cefaclor product alongside the brand versions. A generic has the same active ingredient and must meet the FDA's bioequivalence standard; it usually costs less. Ask your pharmacist which one your plan covers.
