Combination products containing ceftazidime
A combination is a different drug — different dosing, different warnings. It is listed here so you can find it, not so you can substitute it.
How long ceftazidime keeps
The date on a sealed pack is not the only one: some ceftazidime labels start a second clock once the product is opened or mixed, as short as 4 hours.

Full LactMed record for ceftazidime: levels in milk, effects in breastfed infants, and the drugs it would consider insteadLimited information indicates that ceftazidime produces low levels in milk that 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. Ceftazidime and is acceptable in nursing mothers.

What people report to the FDA about ceftazidime
The FDA Adverse Event Reporting System (FAERS) collects reports from patients and clinicians. It holds 10,378 reports naming ceftazidime, and the FDA flagged 96% 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:
- pyrexia684 reports
- septic shock460 reports
- acute kidney injury411 reports
- neutropenia394 reports
- pneumonia381 reports
- sepsis380 reports
- diarrhoea354 reports
- febrile neutropenia341 reports
Read these as a signal, not a rate. A report does not mean ceftazidime 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 ceftazidime 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 ceftazidime 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 ceftazidime sold under?
We track 3 ceftazidime-containing products in the U.S.: Ceptaz, Fortaz and Fortaz in Plastic Container. They are the same active ingredient; they differ in form, manufacturer, price and FDA recall record.
What forms does ceftazidime come in?
Across the brands we track, ceftazidime is currently marketed as injectable, 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 ceftazidime?
We do not currently list a generic-labelled ceftazidime product. That does not always mean none exists — it means none appears under a generic name in the FDA data we track. Ask your pharmacist.
