Duricef (cefadroxil) is a first-generation cephalosporin antibiotic designed to combat a wide spectrum of bacterial infections. As an oral medication, it offers a convenient and potent therapeutic option for both community and clinical settings. Its bactericidal action works by inhibiting bacterial cell wall synthesis, making it a reliable choice for treating susceptible pathogens. Prescribed globally, Duricef remains a cornerstone in empirical and targeted antibiotic therapy, trusted for its established efficacy and favorable safety profile.

Common use
Duricef is commonly prescribed for the treatment of bacterial infections including:
- Pharyngitis and tonsillitis caused by Streptococcus pyogenes
- Skin and soft tissue infections
- Urinary tract infections (uncomplicated)
- Prophylaxis in certain surgical procedures
Always use under medical supervision. Not effective against viral infections.
Dosage and direction
Dosage must be individualized based on infection severity, pathogen susceptibility, and patient condition.
Adults:
- Usual dose: 1–2 g per day, administered once daily or in divided doses (12-hour intervals)
- For skin and soft tissue infections: 1 g daily or 500 mg twice daily
- For urinary tract infections: 1–2 g daily in single or divided doses
Pediatric patients:
- 30 mg/kg/day in divided doses every 12 hours
- Maximum daily dose should not exceed adult recommendations
Take with or without food. Complete the full prescribed course even if symptoms improve.
Precautions
- Use with caution in patients with renal impairment; dosage adjustment may be necessary.
- Prolonged use may result in overgrowth of nonsusceptible organisms.
- Monitor for signs of superinfection.
- Not recommended during pregnancy unless clearly needed; consult healthcare provider.
- May cause diarrhea; advise patients to report severe or persistent cases.
Contraindications
- Known hypersensitivity to cefadroxil or other cephalosporins.
- Patients with a history of severe allergic reactions (e.g., anaphylaxis) to penicillins or other beta-lactam antibiotics.
Possible side effect
Common side effects may include:
- Nausea, vomiting, diarrhea
- Abdominal pain
- Dizziness, headache
- Skin rash or itching
Rare but serious side effects:
- Severe allergic reactions (swelling, difficulty breathing)
- Clostridium difficile-associated diarrhea
- Blood disorders (e.g., neutropenia, thrombocytopenia)
- Liver enzyme elevations
Discontinue and seek medical attention if severe reactions occur.
Drug interaction
- Probenecid may increase cefadroxil blood levels.
- Concurrent use with nephrotoxic drugs (e.g., aminoglycosides) may increase risk of renal toxicity.
- May affect intestinal flora, reducing efficacy of oral contraceptives; advise backup contraception.
- Interaction with warfarin may enhance anticoagulant effect; monitor INR.
Missed dose
Take the missed dose as soon as remembered. If it is almost time for the next dose, skip the missed dose and resume the regular schedule. Do not double the dose.
Overdose
Symptoms may include nausea, vomiting, epigastric distress, and diarrhea. Treatment is supportive; hemodialysis may aid removal. Contact a poison control center or seek emergency medical attention.
