Cefdinir

Cefdinir for oral suspension may be administered without regard to meals. [See table below.] Patients With Renal Insufficiency For adult patients with creatinine clearance < 30 mL/min, the dose of cefdinir should be 300 mg given once daily. Creatinine clearance is difficult to measure in outpatients. However, the following formula may be used to estimate creatinine clearance (CL cr ) in adult patients.

For estimates to be valid, serum creatinine levels should reflect steady-state levels of renal function. [See table below.] where creatinine clearance is in mL/min, age is in years, weight is in kilograms, and serum creatinine is in mg/dL. 1 The following formula may be used to estimate creatinine clearance in pediatric patients: CL cr = K × body length or height serum creatinine where K = 0.55 for pediatric patients older than 1 year 2 and 0.45 for infants (up to 1 year). 3 In the above equation, creatinine clearance is in mL/min/1.73 m 2 , body length or height is in centimeters, and serum creatinine is in mg/dL.

For pediatric patients with a creatinine clearance of < 30 mL/min/1.73 m 2 , the dose of cefdinir should be 7 mg/kg (up to 300 mg) given once daily. Patients on Hemodialysis Hemodialysis removes cefdinir from the body. In patients maintained on chronic hemodialysis, the recommended initial dosage regimen is a 300 mg or 7 mg/kg dose every other day.

At the conclusion of each hemodialysis session, 300 mg (or 7 mg/kg) should be given. Subsequent doses (300 mg or 7 mg/kg) are then administered every other day.
