Synercid should be administered by intravenous infusion in 5% Dextrose in Water solution over a 60-minute period. (See WARNINGS.) An infusion pump or device may be used to control the rate of infusion. If necessary, central venous access (e.g., PICC) can be used to administer Synercid to decrease the incidence of venous irritation. The recommended dosage for the treatment of complicated skin and skin structure infections is 7.5 mg/kg q12h. The minimum recommended treatment duration for complicated skin and skin structure infections is seven days.

Special Populations


No dosage adjustment of Synercid is required for use in the elderly. (See CLINICAL PHARMACOLOGY: Pharmacokinetics and PRECAUTIONS: Geriatric Use.)

Renal Insufficiency

No dosage adjustment of Synercid is required for use in patients with renal impairment or patients undergoing peritoneal dialysis. (See CLINICAL PHARMACOLOGY: Pharmacokinetics.)

Hepatic Insufficiency

Data from clinical trials of Synercid suggest that the incidence of adverse effects in patients with chronic liver insufficiency or cirrhosis was comparable to that in patients with normal hepatic function. Pharmacokinetic data in patients with hepatic cirrhosis (Child Pugh A or B) suggest that dosage reduction may be necessary but exact recommendations cannot be made at this time. (See CLINICAL PHARMACOLOGY: Special Populations and PRECAUTIONS: General: Hepatic Insufficiency sections.)

Pediatric Patients

The recommended dose of Synercid for pediatric patients (12 to < 18 years of age) is 7.5 mg/kg q12h. No dosing recommendations are available in pediatric patients less than 12 years of age. (See PRECAUTIONS: Pediatric Use.)
