Drug

Deutetrabenazine

Pronounced

"DU-tet-ra-BEN-a-zeen"

Uses

Deutetrabenazine is used to decrease involuntary movements (chorea) caused by Huntington's disease. It is also used to treat involuntary movements of the face, tongue, or other body parts (tardive dyskinesia). However, it is not a cure for the Huntington's disease or tardive dyskinesia. Reducing involuntary movements will help you take part in more of your normal daily activities. This medication is thought to work by decreasing the amount of certain natural substances in the brain that affect how your nerves and muscles work (monoamines such as dopamine, serotonin, and norepinephrine).

Warning

If you have Huntington's disease, deutetrabenazine can sometimes increase the risk of depression and suicidal thoughts/attempts. People with Huntington's disease are already more likely to have depression and suicidal thoughts/attempts. Talk with your doctor about the risks and benefits of this medication. People with Huntington's disease and depression must not use deutetrabenazine if they are not being treated for depression or if they still have symptoms of depression with medication/treatment. Tell your doctor right away if you or your family/caregivers notice that you have new/worsening symptoms of depression, sadness, loss of interest in activities you used to enjoy, suicidal thoughts/attempts, or other mental/mood/behavior changes (such as new/worsening anxiety, panic attacks, trouble sleeping, irritability, hostile/angry feelings).
