    Orkambi Warnings/Precautions

    Warnings/Precautions

    If genotype is unknown, use an FDA cleared CF mutation test to detect the presence of the F508del mutation on both alleles of the CFTR gene. Advanced liver disease: monitor closely after initiation and reduce dose. Assess ALT/AST and bilirubin levels prior to initiating therapy, every 3 months during the first year of treatment, and annually thereafter. If ALT/AST or bilirubin levels increased, monitor closely until resolved. Interrupt dosing if ALT/AST is >5XULN or if ALT/AST is >3XULN with bilirubin elevations >2XULN; after resolution, consider restarting. Monitor BP periodically and for respiratory events during treatment initiation in patients with ppFEV1 <40. Perform baseline and follow-up eye exams. Transplanted patients: not recommended. Severe renal impairment (CrCl ≤30mL/min) or ESRD. Pregnancy. Nursing mothers.
