Indication & Usage

CERDELGA (eliglustat) capsules is a glucosylceramide synthase inhibitor indicated for the long-term treatment of adult patients with Gaucher disease type 1 who are CYP2D6 extensive metabolizers (EMs), intermediate metabolizers (IMs), or poor metabolizers (PMs) as detected by an FDA-cleared test.

Limitations of Use:

Important Safety Information

CERDELGA is contraindicated in EMs or IMs taking a strong or moderate CYP2D6 inhibitor concomitantly with a strong or moderate CYP3A inhibitor, and in IMs or PMs taking a strong CYP3A inhibitor due to the risk of significantly increased eliglustat blood concentration, which may result in prolongation of cardiac intervals that could result in cardiac arrhythmias.

Your doctor will perform a test to help determine if CERDELGA is right for you.

Your doctor may need to prescribe a different medicine, change your dose of other medicines, or change your dose of CERDELGA. Tell your doctor about any new medicines before you start taking them.
