What is Austedo (deutetrabenazine) and how is it used?
Austedo is a prescription medicine that is used to treat:
- the involuntary movements (chorea) of Huntington's disease. Austedo does not cure the cause of the involuntary movements, and it does not treat other symptoms of Huntington's disease, such as problems with thinking or emotions.
- movements in the face, tongue, or other body parts that cannot be controlled (tardive dyskinesia).

DEPRESSION AND SUICIDALITY IN PATIENTS WITH HUNTINGTON’S DISEASE
Austedo can increase the risk of depression and suicidal thoughts and behavior (suicidality) in patients with Huntington’s disease. Anyone considering the use of Austedo must balance the risks of depression and suicidality with the clinical need for treatment of chorea. Closely monitor patients for the emergence or worsening of depression, suicidality, or unusual changes in behavior. Patients, their caregivers, and families should be informed of the risk of depression and suicidality and should be instructed to report behaviors of concern promptly to the treating physician.
Particular caution should be exercised in treating patients with a history of depression or prior suicide attempts or ideation, which are increased in frequency in Huntington’s disease. Austedo is contraindicated in patients who are suicidal, and in patients with untreated or inadequately treated depression.
Sleepiness (sedation) is a common side effect of Austedo. While taking Austedo, do not drive a car or operate dangerous machinery until you know how Austedo affects you. Drinking alcohol and taking other drugs that may also cause sleepiness while you are taking Austedo may increase any sleepiness caused by Austedo.
Austedo can cause serious side effects in people with Huntington’s disease, including:
- suicidal thoughts
- suicidal actions
Do not start taking Austedo if you have Huntington's disease and are depressed (have untreated depression or depression that is not well controlled by medicine) or have suicidal thoughts.
Pay close attention to any changes, especially sudden changes, in mood, behaviors, thoughts, or feelings. This is especially important when Austedo is started and when the dose is changed.
Call your healthcare provider right away if you become depressed or have any of the following symptoms, especially if they are new, worse, or worry you:
- feel sad or have crying spells
- lose interest in seeing your friends or doing things you used to enjoy
- sleep a lot more or a lot less than usual
- feel unimportant
- feel guilty
- feel hopeless or helpless
- feel more irritable, angry, or aggressive than usual
- feel more or less hungry than usual or notice a big change in your body weight
- have trouble paying attention
- feel tired or sleepy all the time
- have thoughts about hurting yourself or ending your life
Other side effects of Austedo (deutetrabenazine)
Austedo can cause serious side effects, including:
- Depression and suicidal thoughts or actions in people with Huntington’s disease.
- Irregular heartbeat (QT prolongation). Austedo increases your chance of having certain changes in the electrical activity in your heart. These changes can lead to a dangerous abnormal heartbeat. Taking Austedo with certain medicines may increase this chance.
- If you are at risk of QT prolongation, your healthcare provider should check your heart before and after increasing your Austedo dose above 24 mg a day.
- Neuroleptic Malignant Syndrome (NMS). Call your healthcare provider right away and go to the nearest emergency room if you develop these signs and symptoms that do not have another obvious cause:
- high fever
- stiff muscles
- problems thinking
- very fast or uneven heartbeat
- increased sweating
- Restlessness. You may get a condition where you feel a strong urge to move. This is called akathisia.
- Parkinsonism in people with Huntington’s disease. Symptoms of parkinsonism include: slight shaking, body stiffness, trouble moving, or keeping your balance.
The most common side effects of Austedo in people with Huntington’s disease include:
- inflammation of the nose and throat (nasopharyngitis)
- problems sleeping (insomnia)
These are not all the possible side effects of Austedo. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.
What is the dosage for Austedo (deutetrabenazine)?
- Take Austedo exactly as your healthcare provider tells you to take it.
- Take Austedo by mouth and with food.
- Swallow Austedo tablets whole with water. Do not chew, crush, or break Austedo tablets before swallowing. If you cannot swallow Austedo tablets whole, tell your healthcare provider. You may need a different medicine.

- Your healthcare provider will increase your dose of Austedo each week for several weeks, until you and your healthcare provider find the right dose for you.

Who should not take Austedo?
Do not take Austedo if you:

Genetic Diseases (Disorder Definition, Types, and Examples)
The definition of a genetic disease is a disorder or condition caused by abnormalities in a person's genome. Some types of genetic inheritance include single inheritance, including cystic fibrosis, sickle cell anemia, Marfan syndrome, and hemochromatosis. Other types of genetic diseases include multifactorial inheritance. Still other types of genetic diseases include chromosome abnormalities (for example, Turner syndrome, and Klinefelter syndrome), and mitochondrial inheritance (for example, epilepsy and dementia).
Huntington's disease is the result of degeneration of neurons in areas of the brain. Huntington's disease is an inherited disorder. Early symptoms include mood swings, apathy, depression, and anger uncharacteristic of the individual. Judgement, memory, and other cognitive functions may become impaired. Presymptomatic testing is available for individuals who have a family history of Huntington's disease. Treatment includes medication and therapy for symptoms.
Your health care provider may refer you to a genetic professional. Universities and medical centers also often have affiliated genetic professionals, or can provide referrals to a genetic professional or genetics clinic. Genetic counseling provides patients and family members the tools to make the right choice in regard to test for a disease or condition.
Genetic Testing: Families With Breast Cancer
Breast cancer can be a killer and the decision to get tested to see if a patient is prone to the disease should be discussed with a doctor -- particularly if the woman has a history of breast cancer in her family. Genetic testing can only tell so much about breast cancer risk, however.
