Dosage Regimens for Mycobacterial Infections
For the treatment of disseminated infection due to Mycobacterium avium complex (MAC), BIAXIN Filmtab and BIAXIN Granules are recommended as the primary agents. BIAXIN Filmtab and BIAXIN Granules should be used in combination with other antimycobacterial drugs (e.g. ethambutol) that have shown in vitro activity against MAC or clinical benefit in MAC treatment [see Clinical Studies (14.1)].
For treatment and prophylaxis of mycobacterial infections in pediatric patients, the recommended dose is 7.5 mg/kg every 12 hours up to 500 mg every 12 hours. [See Use in Specific Populations (8.4) and Clinical Studies (14.1)].
Dosage Adjustment in Patients with Renal Impairment
See Table 2 for dosage adjustment in patients with moderate or severe renal impairment with or without concomitant atazanavir or ritonavir-containing regimens [see Drug Interactions (7)].
|Recommended BIAXIN Dosage Reduction|
|Patients with severe renal impairment (CLcr of <30 mL/min)||Reduce the dosage of BIAXIN by 50%|
|Patients with moderate renal impairment (CLcr of 30 to 60 mL/min) taking concomitant atazanavir or ritonavir-containing regimens||Reduce the dosage of BIAXIN by 50%|
|Patients with severe renal impairment (CLcr of <30 mL/min) taking concomitant atazanavir or ritonavir-containing regimens||Reduce the dosage of BIAXIN by 75%|
