Eliglustat is approved for adults with Gaucher disease and compatible CYP2D6 metaboliser genotypes. Distinctive characteristics of eliglustat require additional investigation and monitoring. Recommendations for all other aspects of Gaucher disease remain unchanged. Eliglustat dose is determined by predicted CYP2D6 metaboliser phenotype. Concomitant use of drugs metabolised by CYP2D6 and CYP3A requires eliglustat dose adjustment.
