Austedo Uses: What Patients Need to Know

Austedo is the brand name for deutetrabenazine, a prescription medicine used in adults to treat tardive dyskinesia and chorea associated with Huntington’s disease. It reduces involuntary movements for some people, but it requires individualized prescribing and ongoing medical review because it can cause important side effects and interactions.

What Is Austedo Used For?

Austedo is a prescription medicine containing deutetrabenazine. The main Austedo uses are treating tardive dyskinesia and treating chorea associated with Huntington’s disease in adults. Tardive dyskinesia involves repetitive, unwanted movements that can affect the face, tongue, jaw, trunk, or limbs. Chorea refers to brief, irregular, involuntary movements that may occur in Huntington’s disease.

The medicine is not a cure for either condition. Instead, it is intended to reduce the severity or frequency of movements that interfere with comfort, communication, eating, walking, social activities, or daily independence. The degree of benefit varies, and a clinician will assess whether improvement outweighs possible side effects for each individual.

Austedo is generally prescribed by a clinician familiar with movement disorders, neurology, or the psychiatric medicines that can contribute to tardive dyskinesia. It should be taken only as prescribed and should not be shared with another person, even if their symptoms appear similar.

How Austedo Works in the Nervous System

Deutetrabenazine belongs to a group of medicines called vesicular monoamine transporter 2, or VMAT2, inhibitors. It changes how certain chemical messengers, including dopamine, are handled within nerve cells. This can lessen the abnormal movement signals involved in tardive dyskinesia and Huntington’s disease chorea.

Because brain chemical pathways are complex, the effect is carefully monitored over time. A clinician may start with a lower amount and adjust it gradually according to symptom control and tolerability. The appropriate regimen depends on the condition being treated, other medicines being used, and the person’s overall health.

Improvement may be noticed gradually rather than immediately. Follow-up appointments allow the care team to ask about movement symptoms, mood, sleep, alertness, balance, and any difficulties with day-to-day activities.

Conditions Treated With Austedo

For tardive dyskinesia, Austedo may be considered when involuntary movements develop after exposure to medicines that block dopamine receptors, most often certain antipsychotic medicines. These movements can persist even after the original medicine is reduced or stopped, although treatment changes should always be led by the prescribing clinician. Learn more about tardive dyskinesia and the importance of a specialist assessment.

For Huntington’s disease, Austedo is used specifically for chorea. Huntington’s disease is an inherited neurological condition that can affect movement, thinking, and emotional health. Reducing chorea may improve function or safety for some people, but other Huntington’s disease symptoms may need separate support and treatment.

Austedo is not suitable for every involuntary movement. Tremor, tics, dystonia, restless legs symptoms, seizures, and medication-related restlessness can have different causes and may require different approaches. A clear diagnosis is therefore an essential step before treatment begins.

Before Starting Austedo: Important Safety Review

Before prescribing Austedo, the clinician should review the person’s medical history, current symptoms, and complete list of prescription medicines, non-prescription products, vitamins, and herbal supplements. This is particularly important because some medicines can raise deutetrabenazine levels or increase side effects. Patients should not start or stop another medicine without checking with their care team.

Mental health history deserves careful attention. Austedo can increase the risk of depression and suicidal thoughts or actions in people with Huntington’s disease. It is contraindicated in people with Huntington’s disease who are suicidal or who have untreated or inadequately treated depression. A clinician can help determine whether another option, closer monitoring, or mental health support is needed.

The care team may also ask about liver disease, irregular heartbeat, fainting, Parkinson’s disease or parkinsonism, falls, pregnancy, breastfeeding, and past reactions to VMAT2 inhibitors. Austedo has important restrictions with some medicines, including reserpine and monoamine oxidase inhibitors, and it should not be used at the same time as certain other VMAT2 inhibitors.

• Bring an up-to-date medication list to every appointment.
• Tell the clinician about new low mood, anxiety, unusual behavior, or thoughts of self-harm.
• Report any history of heart rhythm problems or unexplained fainting.
• Ask whether driving, alcohol use, or operating machinery is safe while learning how the medicine affects alertness.

Possible Side Effects and Monitoring

Side effects can occur with any medicine, and many are manageable when identified early. Commonly reported effects may include sleepiness, tiredness, diarrhea, dry mouth, insomnia, anxiety, or fatigue, depending on the condition being treated. Sleepiness can affect driving, work, and fall risk, especially when combined with alcohol or other sedating medicines.

Some people may develop or experience worsening parkinsonism, such as stiffness, slowed movement, tremor, problems with balance, or difficulty walking. Restlessness, agitation, and changes in mood should also be discussed promptly. The clinician may adjust treatment or investigate other possible causes of these symptoms.

Austedo may affect the heart’s electrical rhythm in susceptible individuals, including by prolonging the QT interval. The relevance of this risk depends on personal and family history, electrolyte balance, heart disease, and interacting medicines. The prescriber may recommend additional assessment when appropriate.

Patients and caregivers can support safe monitoring by noting changes in movements, mood, sleep, alertness, walking, and daily function. Keeping a brief symptom record between appointments can make follow-up discussions more useful.

Taking Austedo Safely and Supporting Daily Life

Austedo should be taken exactly according to the directions on its prescription label. It is commonly taken with food, and tablets should be swallowed whole rather than chewed, crushed, or split. The clinician will explain what to do if a dose is missed and how to handle interruptions in treatment.

People should not change the dose on their own, even if movements seem worse or side effects occur. If treatment has been interrupted for more than a short period, the prescriber may need to advise on restarting rather than simply resuming the previous regimen. This helps reduce avoidable side effects and supports safe symptom control.

Medication is only one part of care. Depending on the condition, support may include reviewing the medicines that may contribute to movement symptoms, physiotherapy, occupational therapy, speech and swallowing assessment, mental health care, and practical fall-prevention measures. A specialist-led neurology evaluation can help coordinate these needs.

For people with Huntington’s disease, family support and advance planning can be valuable alongside medical management. For tardive dyskinesia, it is especially important not to discontinue psychiatric medication abruptly; the original prescriber and movement-disorder clinician can work together to balance mental health and movement-related needs.

When to Seek Medical Care

Contact the prescribing clinician soon if involuntary movements worsen, new stiffness or shaking develops, excessive sleepiness affects safety, or there are new concerns about mood, anxiety, agitation, or behavior. Family members and caregivers should also report changes, as the person taking the medicine may not always recognize them.

Urgent medical help is needed for suicidal thoughts, plans to self-harm, severe confusion, fainting, a fast or irregular heartbeat, severe trouble breathing, or a serious allergic reaction such as swelling of the face or throat. These symptoms need prompt assessment rather than waiting for a routine appointment.

People experiencing new involuntary movements should arrange a medical evaluation rather than assuming the cause. Accurate diagnosis can identify treatable contributors and guide the most appropriate care. Acibadem International’s multidisciplinary specialists and JCI-accredited hospitals evaluate and treat movement disorders for international patients.

Frequently asked questions

What are the main Austedo uses?

Austedo is used in adults to treat tardive dyskinesia and chorea associated with Huntington’s disease. It is intended to reduce involuntary movements, not to cure the underlying condition.

Is Austedo the same as a treatment for Parkinson’s disease?

No. Austedo is not generally used to treat Parkinson’s disease. In some people, it can cause or worsen parkinsonism-like symptoms, so new stiffness, slowed movement, tremor, or balance problems should be reported to a clinician.

How quickly does Austedo begin to work?

The timing and degree of benefit vary between individuals. The dose is usually adjusted gradually, and clinicians assess movement symptoms and side effects during follow-up visits.

Can Austedo cause depression?

Austedo can increase the risk of depression and suicidal thoughts or actions in people with Huntington’s disease. Anyone with new or worsening low mood, hopelessness, unusual behavior, or thoughts of self-harm should contact a healthcare professional promptly.

Can a person stop taking Austedo suddenly?

A person should not stop, restart, or change Austedo without advice from the prescribing clinician. If treatment is interrupted, the clinician may need to provide specific instructions for restarting safely.

What medicines can interact with Austedo?

Several medicines can interact with Austedo, including certain antidepressants, medicines that affect heart rhythm, monoamine oxidase inhibitors, reserpine, and other VMAT2 inhibitors. A pharmacist or clinician should review all prescription medicines, over-the-counter products, and supplements before treatment starts and whenever they change.
