How long does Cefdinir stay in your body?

The elimination half-life of cefdinir is about 1.7 hours — the time it takes the body to clear about half of it. As a rule of thumb, a medicine is mostly gone after roughly 4 to 5 half-lives, though this varies from person to person with age and kidney or liver function. First-order (linear) elimination, principally renal. Cefdinir is not appreciably metabolized and activity is due to the parent drug, so there is no active metabolite and it is not a prodrug. Half-life is prolonged in kidney impairment (roughly 2-fold at CLcr 30–60 mL/min and about 5-fold at CLcr under 30 mL/min); in the elderly the half-life is essentially unchanged (2.2 vs 1.8 hours) with higher exposure driven by reduced clearance rather than a longer half-life.

Frequently asked questions

What does Omnicef treat?

Omnicef (Cefdinir) may be used to treat bronchitis, escherichia coli infections, haemophilus infections, klebsiella infections, otitis media, proteus infections, based on NIH RxClass drug-classification data (conditions a drug may treat — not a verbatim copy of the FDA-approved label). This is general reference, not medical advice.

How does Omnicef work?

Omnicef is a cephalosporin antibacterial. Cephalosporins kill bacteria by blocking the proteins they use to build their cell walls. Without an intact wall, the bacterium cannot hold its shape and dies, which clears the infection.

How is Omnicef rated?

pharmaranks gives Omnicef a composite score of 3.6 out of 5, currently based on 1 weighted source (FDA regulatory recall-safety data weighted highest). See our methodology at /how-we-rate.

How much does Omnicef cost?

Nobody can tell you what you will pay — your price is set by your insurer's formulary, your deductible and the pharmacy's markup, and none of those are published. What IS published is what the pharmacy paid to acquire it: about $0.12 per ml, per the CMS NADAC survey. Treat that as the floor, not the quote — ask the pharmacist for the cash price as well as your copay, because for cheap generics the cash price often wins.

Is there a coupon or discount for Omnicef?

pharmaranks is an independent ratings site, not a pharmacy — we don't issue coupons or sell Omnicef. To pay less, ask your prescriber or pharmacist whether a generic equivalent exists, check the manufacturer's copay/savings card and patient-assistance program, and compare a pharmacy discount card against your insurance copay. Prices vary by pharmacy, insurance, and location, so always confirm at the counter. This is general reference, not medical or financial advice.
