Treatment with Cerdelga

  1. Is Cerdelga right for you?

    Before your doctor can determine if you are a candidate to take Cerdelga, he or she must determine your CYP2D6 metabolizer status. A genetic test (a simple blood test) can determine your CYP2D6 metabolizer status.

    Understanding whether treatment with Cerdelga is right for you starts by understanding your CYP2D6 metabolizer status. CYP2D6 metabolizer status describes your body’s ability to break down (metabolize) certain drugs, including Cerdelga.


  2. Getting access to Cerdelga

    Sanofi Genzyme Case Managers are available to assess your unique situation and help you understand your insurance options for Cerdelga.

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.

CERDELGA can affect the way other medicines work and other medicines can affect how CERDELGA works. Using CERDELGA with other medicines or herbal supplements (including St. John’s Wort) may cause an increased risk of side effects, including ECG changes and irregular heart beat. Especially tell your doctor if you take medicines for fungal infections, tuberculosis, seizures, heart rhythm and rate problems, high blood pressure, or depression or other mental health problems. 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.

Before taking CERDELGA, tell your doctor about all of your medical conditions, including kidney or liver problems, history of heart attacks, or heart rhythm problems (including long QT syndrome). If you are pregnant or plan to become pregnant or breastfeed, talk to your physician. It is not known if CERDELGA will harm your unborn baby.

It is not known if CERDELGA is safe and effective in children.

Swallow the capsule whole, preferably with water. If you miss a dose of CERDELGA, take the next dose at the usual time. Do not take two doses of CERDELGA at the same time. Avoid eating or drinking grapefruit products while taking CERDELGA. Grapefruit products can increase the amount of CERDELGA in your body.

The most common adverse reactions (≥10%) for CERDELGA are: fatigue, headache, nausea, diarrhea, back pain, pain in extremities, and upper abdominal pain. Call your doctor for medical advice about adverse effects.
