What is deutetrabenazine?
Deutetrabenazine reduces the amount of certain chemicals in the body that are overly active in people with Huntington's disease.
Deutetrabenazine is used to treat involuntary muscle movements (chorea) caused by Huntington's disease. Deutetrabenazine is not a cure for Huntington's disease and will not treat other symptoms of this condition.
Deutetrabenazine is used to treat symptoms of tardive dyskinesia, a nervous system disorder. Tardive dyskinesia causes repetitive uncontrolled muscle movements, usually in the face (chewing, lip smacking, frowning, tongue movement, blinking or eye movement).
Deutetrabenazine is not a permanent cure for involuntary movement disorders.
Deutetrabenazine may also be used for purposes not listed in this medication guide.
What should I discuss with my healthcare provider before taking deutetrabenazine?
You should not use deutetrabenazine if you are allergic to it, or if you have:
- untreated or uncontrolled depression;
- thoughts about suicide or hurting yourself;
- liver disease; or
- if you have recently taken tetrabenazine (Xenazine) or valbenazine (Ingrezza).
Do not use deutetrabenazine if you have taken reserpine (Serpalan, Renese-R) in the past 20 days, or if you have used an MAO inhibitor in the past 14 days. A dangerous drug interaction could occur. MAO inhibitors include isocarboxazid, linezolid, methylene blue injection, phenelzine, rasagiline, selegiline, tranylcypromine, and others.
To make sure deutetrabenazine is safe for you, tell your doctor if you have ever had:
- depression, anxiety, nervousness, or agitation;
- a history of mental illness or psychosis;
- suicidal thoughts or actions;
- breast cancer;
- a heart rhythm disorder;
- a personal or family history of long QT syndrome; or
- an electrolyte imbalance (such as low levels of potassium or magnesium in your blood).
People with Huntington's disease may have a higher risk of depression and suicidal thoughts or behaviors. Taking deutetrabenazine may further increase this risk. However, the benefits of taking this medicine (improvement in daily living) may outweigh any suicidal risks.
Your doctor should check your progress at regular visits. Your family or other caregivers should also be alert to changes in your mood or symptoms.
