What is Cefdinir?
Cefdinir is a third-generation cephalosporin antibiotic used to treat a wide range of mild-to-moderate bacterial infections. It works by inhibiting bacterial cell wall synthesis and is effective against bacteria causing infections of the ears, sinuses, throat, lungs, and skin. It is not effective against viral infections. The medication was formerly known as Omnicef and is now primarily available as a generic.
Understanding Adult Cefdinir Dosage
For most adults and adolescents aged 13 and older, a typical cefdinir dosage is often part of a standard total daily dose. This daily dose is usually administered in one of two ways, typically involving individual doses:
- Divided doses: Administering the total daily dose in multiple smaller amounts throughout the day is common for various infections, including some respiratory and skin infections.
- Single daily dose: Taking the entire daily prescribed amount at one time may be used for certain conditions such as acute exacerbations of chronic bronchitis, tonsillitis, and acute maxillary sinusitis.
Therefore, an individual dose is usually one part of a standard treatment plan and not considered excessive for adults, depending on the total daily amount prescribed by a healthcare professional.
Factors that Influence Cefdinir Dosage
A healthcare provider determines the appropriate cefdinir dose based on several factors:
Type and Severity of Infection
Dosage and duration depend on the specific infection. For instance, community-acquired pneumonia may require a specific regimen over a set number of days, while other infections might differ.
Patient Age and Weight
Pediatric dosage for children (6 months to 12 years) is typically weight-based and does not exceed a certain daily amount. This leads to smaller individual doses than for adults.
Kidney Function
Adults with significantly reduced kidney function require a dosage reduction, as cefdinir is cleared by the kidneys. Pediatric patients with kidney issues also need dose adjustments.
Medication Interactions
Certain antacids and iron supplements can reduce cefdinir absorption. They should be taken at least two hours before or after cefdinir.
Cefdinir Dosage Comparison Table
A comparison of common adult cefdinir dosages for various conditions includes community-acquired pneumonia, acute exacerbations of chronic bronchitis, acute maxillary sinusitis, pharyngitis/tonsillitis, and uncomplicated skin infections. These conditions may require regimens involving specific doses administered at intervals or once daily, with treatment durations typically ranging from 5 to 10 days. The dosing frequency can depend on the condition being treated. For a detailed table, consult {Link: MedCentral https://www.medcentral.com/drugs/monograph/5543-398001/cefdinir-oral}.
Potential Side Effects of Cefdinir
Common side effects are generally mild and can include diarrhea, nausea, stomach pain, headache, and vaginal yeast infections. More severe but less frequent effects needing medical attention include C. diff-associated diarrhea, allergic reactions, and kidney issues. Taking cefdinir with iron can cause reddish stools, which is harmless.
Safe and Effective Use of Cefdinir
Always follow your doctor's instructions precisely and complete the full course of cefdinir, even if symptoms improve. Early discontinuation can cause the infection to return and contribute to antibiotic resistance. Inform your doctor about any pre-existing conditions, especially kidney disease.

Conclusion
In conclusion, understanding what constitutes a standard dose of cefdinir is dependent on the individual prescription for a bacterial infection. Dosage is tailored based on infection type, patient age, and kidney function. Following your healthcare provider's specific guidance is essential for effective treatment and preventing resistance.
