Deutivacaftor/tezacaftor/vanzacaftor Disease Interactions

Elexacaftor (available only in combination with ivacaftor and tezacaftor) should not be used in patients with severe hepatic impairment and its use in patients with moderate hepatic impairment should be limited to those patients for which there is a clear medical need and the benefit exceeds the risks. If elexacaftor is used in patients with moderate hepatic impairment, the dose should be reduced and liver function tests should be closely monitored.

Elexacaftor (available only in combination with ivacaftor and tezacaftor), has not been studied in patients with severe renal impairment or end-stage renal disease. No dosage adjustment is recommended in patients with mild (eGFR 60 to <90 mL/min/1.73 m2) or moderate (eGFR 30 to <60 mL/min/1.73 m2) renal impairment. Use with caution in patients with severe (eGFR <30 mL/min/1.73 m2) renal impairment or end-stage renal disease.
