GENERIC AVAILABLE: Yes
PREPARATIONS: Capsules: 300 mg. Oral suspension: 125 and 250 mg/5 mL
STORAGE: Cefdinir should be stored at room temperature, between 59 F to 86 F (15 C to 30 C). The suspension may be stored at room temperature for up to 10 days after mixing.
PRESCRIBED FOR: Cefdinir is effective against susceptible bacteria causing infections of the middle ear (otitis media), tonsils (tonsillitis), throat, larynx (laryngitis), sinuses (sinusitis), bronchi (bronchitis), lungs (pneumonia), skin and other soft tissues.
DOSING: Cefdinir is taken once or twice daily, depending on the type and severity of the infection. The capsules or suspension can be taken with or without food. Patients with advanced kidney disease may need to take lower doses to prevent accumulation of cefdinir since it is eliminated from the body by the kidneys.
For adult infections the usual dose is 300 mg every 12 hours or 600 mg per day for 5-10 days depending on the nature and severity of the infection.
The recommended dose for children 6 months to 12 years of age is 7 mg/kg every 12 hours or 14 mg/kg per day for 5-10 days depending on the type of infection.
For most infections, once daily dosing is as effective as twice daily dosing, although once daily dosing has not been evaluated for the treatment of skin infections or pneumonia.
DRUG INTERACTIONS: Aluminum or magnesium containing antacids reduce the absorption of cefdinir from the intestine. Separating the administration of cefdinir and such antacids by two hours prevents this interaction.
Iron supplements also reduce the absorption of cefdinir. Separating the administration of cefdinir and iron supplements by two hours prevents this interaction. There have been reports of reddish stool in patients who have received cefdinir. This could be due to the formation of a chemical complex between cefdinir and iron in the stomach.
PREGNANCY: There are no adequate studies of cefdinir in pregnant women; however, studies in animals suggest no important effects on the fetus.
