Generic Cefdinir Information

Introduction

Cefdinir is an oral third‑generation cephalosporin antibiotic used to treat a range of bacterial infections. In Hong Kong it is prescribed by doctors and dispensed through licensed pharmacies, including online services that comply with local regulations. The active compound is Cefdinir; the medication belongs to the Antibiotics group. It is indicated for respiratory, sinus, skin, and ear infections caused by susceptible organisms.

What is Cefdinir?

Cefdinir is a synthetic β‑lactam antibiotic that belongs to the third‑generation cephalosporins. It was first approved by the U.S. Food and Drug Administration (FDA) in 1991 and is now produced by several multinational pharmaceutical companies.

Cefdinir is the generic version of Omnicef, containing the same active compound Cefdinir. Our online pharmacy provides this generic alternative as a cost‑effective treatment option for patients in Hong Kong who need an approved oral cephalosporin.

How Cefdinir Works

Cefdinir inhibits bacterial cell‑wall synthesis by binding to penicillin‑binding proteins (PBPs) on the inner surface of the bacterial membrane. This binding blocks the cross‑linking of peptidoglycan strands, a critical step in cell‑wall formation. Without a functional wall, bacteria become osmotically unstable and lyse, leading to bacterial death.

The drug’s bactericidal activity begins shortly after oral absorption, with peak plasma concentrations reached in 2–4 hours. Cefdinir is primarily excreted unchanged by the kidneys; its half‑life in adults with normal renal function is approximately 1.7 hours, supporting once‑or twice‑daily dosing for most infections.

Conditions Treated with Cefdinir

• Acute bacterial sinusitis – targets Streptococcus pneumoniae and Haemophilus influenzae, common pathogens in Hong Kong’s humid climate.
• Community‑acquired pneumonia (CAP) – effective against atypical and typical organisms, useful when first‑line macrolides are contraindicated.
• Acute bacterial otitis media – covers Streptococcus and Haemophilus species responsible for middle‑ear infections.
• Uncomplicated skin and soft‑tissue infections (SSTIs) – treats Staphylococcus aureus (methicillin‑susceptible) and Streptococcus pyogenes.
• Pharyngitis/tonsillitis – indicated when rapid strep testing confirms susceptible streptococcal infection.

These indications are supported by clinical guidelines from the Hong Kong Hospital Authority and international infectious disease societies.

Patient Groups Most Likely to Benefit

• Adults with mild‑to‑moderate respiratory infections where β‑lactam therapy is appropriate.
• Patients allergic to penicillins (non‑cross‑reactive) who require a cephalosporin alternative.
• Individuals with renal function ≥ 30 mL/min who can tolerate standard dosing.
• Outpatient settings where intravenous therapy is unnecessary or unavailable.

Cefdinir is not recommended for patients with severe renal impairment (creatinine clearance < 30 mL/min without dose adjustment, or for infections caused by known β‑lactam‑producing resistant organisms (e.g., ESBL‑producing Enterobacteriaceae).

Risks, Side Effects, and Interactions

Common

• Gastrointestinal upset – nausea, diarrhea, abdominal pain.
• Transient rash – mild maculopapular eruptions that resolve after discontinuation.
• Headache – usually mild and self‑limiting.

Rare

• Clostridioides difficile‑associated diarrhea – may develop weeks after therapy.
• Hepatic enzyme elevations – transient rise in ALT/AST without clinical hepatitis.
• Peripheral eosinophilia – asymptomatic laboratory finding.

Serious

• Severe hypersensitivity reactions – Stevens‑Johnson syndrome, anaphylaxis, or serum sickness‑like reactions.
• Serum creatinine rise – indicating potential renal toxicity, especially in patients with pre‑existing kidney disease.
• Seizures – rare, usually in patients with high plasma concentrations due to renal failure.

Drug–Drug Interactions

• Antacids containing aluminum or magnesium – decrease Cefdinir absorption; take on an empty stomach or separate by at least 2 hours.
• Warfarin – may potentiate anticoagulant effect; monitor INR closely.
• Probenecid – reduces renal excretion, increasing Cefdinir plasma levels; dose adjustment may be required.
• Live bacterial vaccines – concurrent use may reduce vaccine efficacy; postpone vaccination for at least 2 weeks after completing therapy.

Patients should disclose all medicines, supplements, and herbal products to their prescriber.

Practical Use: Dosing, Missed Dose, Overdose

• Standard adult dosing: 300 mg orally every 12 hours for sinusitis, pneumonia, or otitis media; 600 mg once daily for uncomplicated SSTIs. Adjust dose to 150 mg twice daily if creatinine clearance is 30‑50 mL/min.
• Administration: Swallow capsules whole with a full glass of water. Do not crush or chew, as this may affect drug release.
• Missed dose: Take the missed dose as soon as remembered unless the next scheduled dose is due within 2 hours; in that case skip the missed dose and continue the regular schedule. Do not double‑dose.
• Overdose: Symptoms may include nausea, vomiting, and abdominal cramps. Seek immediate medical attention; supportive care and gastric lavage are the primary measures. Cefdinir has low toxicity in overdose, but renal monitoring is advised.
• Food and alcohol: Food does not markedly affect absorption, but high‑fat meals may delay peak levels slightly. Moderate alcohol consumption does not interact directly, but excessive intake can exacerbate gastrointestinal side effects.
