Renal Dosing
Renal Impairment:
Penicillin G is relatively nontoxic, and dosage adjustments are
generally required only in cases of severe renal impairment. The
recommended dosage regimens are as follows:
Creatinine clearance less than 10 mL/min/1.73m2; administer a full
loading dose (see recommended dosages in the tables above) followed by
one-half of the loading dose every 8-10 hours.
Uremic patients with a creatinine clearance greater than 10 mL/min/1.73m2;
administer a full loading dose (see recommended dosages in the tables
above) followed by one-half of the loading dose every 4-5 hours.
Additional dosage modifications should be made in patients with hepatic
disease and renal impairment.
