Moxifloxacin

Renal Impairment The pharmacokinetic parameters of moxifloxacin are not significantly altered in mild, moderate, severe, or end-stage renal disease. No dosage adjustment is necessary in patients with renal impairment, including those patients requiring hemodialysis (HD) or continuous ambulatory peritoneal dialysis (CAPD). [See Dosage and Administration , and Clinical Pharmacology .]

Hepatic Impairment No dosage adjustment is recommended for mild, moderate, or severe hepatic insufficiency (Child-Pugh Classes A, B, or C). However, due to metabolic disturbances associated with hepatic insufficiency, which may lead to QT prolongation, moxifloxacin hydrochloride should be used with caution in these patients [see Warnings and Precautions, and Clinical Pharmacology ] .

Important Administration Instructions With Multivalent Cations Administer moxifloxacin tablets at least 4 hours before or 8 hours after products containing magnesium, aluminum, iron or zinc, including antacids, sucralfate, multivitamins and didanosine buffered tablets for oral suspension or the pediatric powder for oral solution [see Drug Interactions and Clinical Pharmacology].

With Food Moxifloxacin tablets can be taken with or without food, drink fluids liberally. Missed Doses If a dose is missed, it should be taken anytime but not later than 8 hours prior to the next scheduled dose. If less than 8 hours remain before the next dose, the missed dose should not be taken and treatment should be continued as prescribed with the next scheduled dose.

Double doses should not be taken to compensate for a missed dose.
