How does this medication work? What will it do for me?
Eliglustat belongs to the class of medications called alimentary tract and metabolism products. It is used to treat a genetic disorder called Type 1 Gaucher Disease.
In Gaucher Disease Type 1 (GD1), the body is not able to break down a fat called glucosylceramide, which is produced by the body. This fat then builds up in the liver, spleen and bone. Eliglustat blocks the fat from being produced, reducing its build-up on organs and helping them to work better.
This medication may be available under multiple brand names and/or in several different forms. Any specific brand name of this medication may not be available in all of the forms or approved for all of the conditions discussed here. As well, some forms of this medication may not be used for all of the conditions discussed here.
Your doctor may have suggested this medication for conditions other than those listed in these drug information articles. If you have not discussed this with your doctor or are not sure why you are taking this medication, speak to your doctor. Do not stop taking this medication without consulting your doctor.
Do not give this medication to anyone else, even if they have the same symptoms as you do. It can be harmful for people to take this medication if their doctor has not prescribed it.
What form(s) does this medication come in?
Each hard gelatin capsule, with a blue-green opaque cap and white opaque body, imprinted with "GZ02C" in black, contains 84 mg of eliglustat as eliglustat tartrate (hemitartrate salt). Nonmedicinal ingredients: glyceryl behenate/glycerol dibehenate, hypromellose, lactose monohydrate, microcrystalline cellulose; capsule shell: gelatin, titanium dioxide (E171), yellow iron oxide (E172) and indigotine (E132); printing ink: shellac glaze, black iron oxide (E172), propylene glycol and ammonium hydroxide 28%.
How should I use this medication?
The recommended dose depends on liver function, specifically how well the CYP2D6 enzyme works to metabolize (break down) medications. This will be determined by a blood test that will be done before you start treatment.
The recommended dose for intermediate and extensive CYP2D6 metabolizers is 84 mg taken by mouth 2 times a day.
The recommended dose of poor CYP2D6 metabolizers is 1 capsule taken by mouth, once daily.
This medication works best if it is taken at the same time each day.
Swallow the capsules whole with water. Do not crush, dissolve or chew the capsules. This medication may be taken with food or on an empty stomach. Do not drink grapefruit juice while taking this medication as it can cause increased blood levels of eliglustat.
Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are taking the medication without consulting your doctor.

If you miss a dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed one. If you are not sure what to do after missing a dose, contact your doctor or pharmacist for advice.

Certain medications (e.g., sotalol, quinidine, thioridazine, chlorpromazine, pimozide, moxifloxacin, mefloquine, pentamidine, arsenic trioxide, probucol, tacrolimus) can increase the risk of several types of abnormal heart rhythm including QT prolongation, and should not be used in combination with eliglustat. You are more at risk for this type of abnormal heart rhythm and its complications if you:
- are female
- are older than 65 years of age
- have a family history of sudden cardiac death
- have a history of heart disease or abnormal heart rhythms
- have a slow heart rate
- have congenital prolongation of the QT interval
- have diabetes

If you have heart disease and abnormal heart rhythms, or are taking certain medications (e.g., verapamil, atazanavir), discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Kidney Function: Eliglustat is not recommended for people with moderate to severe kidney disease or decreased kidney function. This medication has not been studied for use by people with decreased kidney function.
Liver function: The safety and effectiveness of having decreased liver function and using eliglustat have not been determined. This medication is not recommended for people with liver disease or decreased liver function.
Pregnancy: This medication should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking this medication, contact your doctor immediately.
