Cefdinir, commonly known by its brand name Omnicef, is a third-generation cephalosporin antibiotic that has been widely prescribed for various bacterial infections since its approval by the FDA in 1997. As a member of the cephalosporin class, cefdinir works by inhibiting the synthesis of the bacterial cell wall, ultimately leading to the death of the bacterial cells. This article aims to provide an in-depth look at cefdinir, covering its uses, dosage, side effects, and other essential information that patients and healthcare professionals need to know.
What is Cefdinir Used For?
Cefdinir is primarily used to treat bacterial infections, including pneumonia, bronchitis, and sinusitis. It is also effective against skin infections, such as cellulitis, and urinary tract infections (UTIs). The antibiotic is particularly useful in treating infections caused by susceptible strains of bacteria, including Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis.
Dosage and Administration
The recommended dosage of cefdinir varies depending on the age and weight of the patient, as well as the type and severity of the infection. For adults and adolescents (13 years and older), the typical dosage is 300 mg twice daily or 600 mg once daily for 5-10 days. For children (6 months to 12 years), the dosage is based on their weight, with a usual dose of 7 mg/kg twice daily or 14 mg/kg once daily. It is essential to complete the full course of treatment, even if symptoms improve before finishing the medication.
| Dosage Form | Strength |
|---|---|
| Capsules | 300 mg |
| Oral Suspension | 125 mg/5 mL, 250 mg/5 mL |
Potential Side Effects and Interactions
Like all medications, cefdinir can cause side effects, some of which can be serious. Common side effects include diarrhea, nausea, and abdominal pain. More severe reactions, such as allergic responses, anaphylaxis, and Clostridioides difficile-associated diarrhea, can occur but are rare. Cefdinir may also interact with other medications, including antacids, iron supplements, and certain antibiotics. Patients should inform their healthcare provider about all medications and supplements they are taking.
Precautions and Contraindications
Cefdinir is contraindicated in patients with a known allergy to cephalosporins or any component of the medication. It should be used with caution in patients with a history of allergic reactions to penicillins or other beta-lactam antibiotics. Additionally, cefdinir should be used with caution in patients with renal impairment, as dosage adjustments may be necessary.
