Austedo is a prescription medication approved by the US Food and Drug Administration for the treatment of involuntary movement disorders, specifically chorea associated with Huntington’s disease and tardive dyskinesia. These conditions can significantly affect daily functioning, emotional well being, and quality of life. Austedo helps manage symptoms by targeting specific pathways in the brain that control movement, though it does not cure the underlying neurological diseases.
In this comprehensive guide, we will explore what Austedo is, how it works, who it is for, possible side effects, dosing instructions, safety warnings, drug interactions, and cost considerations. This article is designed for patients, caregivers, and anyone seeking reliable, easy to understand information about Austedo.
Austedo is the brand name for deutetrabenazine, a medication that belongs to a drug class called VMAT2 inhibitors. VMAT2 stands for vesicular monoamine transporter 2, a protein that helps regulate how neurotransmitters such as dopamine are stored and released in nerve cells.
By inhibiting VMAT2, Austedo reduces excessive dopamine signaling in parts of the brain responsible for involuntary movements. This leads to fewer uncontrolled muscle contractions, jerking, twitching, and facial movements.
Austedo is available in two formulations:
Both forms are prescription only medications.
Tardive dyskinesia, often abbreviated as TD, is a neurological condition that causes repetitive, involuntary movements. These movements commonly affect the face, mouth, tongue, and eyes, but can also involve the arms, legs, and torso.
TD is usually caused by long term use of certain medications, especially antipsychotic drugs used to treat mental health conditions. Symptoms may include lip smacking, chewing motions, blinking, tongue thrusting, or grimacing.
Austedo helps reduce the severity and frequency of these movements, allowing many patients to regain confidence and function in daily activities.
Huntington’s disease is a genetic neurodegenerative disorder that leads to progressive damage of nerve cells in the brain. One of its hallmark symptoms is chorea, which refers to sudden, unpredictable, involuntary movements of the arms, legs, face, and tongue.
Austedo is approved to treat chorea related to Huntington’s disease. It does not slow disease progression or treat cognitive or psychiatric symptoms. Its role is strictly to manage involuntary movements.
The brain relies on chemical messengers called neurotransmitters to send signals between nerve cells. Dopamine is one of these messengers and plays a major role in movement control.
VMAT2 is a protein that packages dopamine into storage vesicles inside nerve cells. Austedo blocks VMAT2, which reduces the amount of dopamine released into synapses. Lower dopamine activity in certain brain regions leads to improved control of involuntary movements.
Because this mechanism affects brain chemistry, careful dosing and monitoring are essential.
Austedo dosing is individualized based on the condition being treated, patient response, and tolerability. Doctors typically start with a low dose and gradually increase it.
When switching between the immediate release and extended release versions, patients should remain on the same total daily dose unless instructed otherwise by a healthcare provider.
Many patients tolerate Austedo well, but side effects may occur, especially during dose adjustments.
Common side effects include:
These effects are often mild and may improve as the body adjusts.
Some side effects require immediate medical attention.
Seek urgent care if you experience:
Patients with Huntington’s disease are at increased risk for depression and suicidal thoughts. Close monitoring by caregivers and healthcare providers is critical.
Austedo is not suitable for everyone. It should not be used in patients with untreated or uncontrolled depression or active suicidal thoughts.
Important safety warnings include:
Patients should inform their doctor of all medical conditions, including heart rhythm disorders, liver disease, electrolyte imbalances, or mental health history.
Austedo can interact with many prescription and over the counter medications.
Notable interactions include:
Always provide a complete medication list to your healthcare provider before starting Austedo.
The cost of Austedo varies depending on insurance coverage and pharmacy pricing. Without insurance, Austedo can be expensive.
Teva Pharmaceuticals offers a copay card for eligible patients with commercial or private insurance. Patients enrolled in government funded programs such as Medicare or Medicaid are generally not eligible.
Patients are encouraged to check official pricing guides and speak with their pharmacist or healthcare provider about financial assistance options.
| Medication Name | Active Ingredient | Approved Uses | Dosing Frequency |
|---|---|---|---|
| Austedo | Deutetrabenazine | TD and Huntington’s chorea | Once or twice daily |
| Ingrezza | Valbenazine | Tardive dyskinesia | Once daily |
| Xenazine | Tetrabenazine | Huntington’s chorea | Multiple daily doses |
Each medication has unique benefits and risks. The best choice depends on individual patient needs and medical history.
Caregivers should monitor behavior closely, especially during the first few months of treatment.
Some patients notice improvement within a few weeks, but full benefits may take longer as the dose is gradually adjusted.
Weight gain is not a common side effect, but individual responses may vary.
No. Austedo only treats involuntary movements and does not cure or slow the progression of Huntington’s disease.
Austedo is an important treatment option for people living with tardive dyskinesia or chorea associated with Huntington’s disease. By targeting VMAT2, it helps reduce involuntary movements and improve quality of life for many patients. However, it requires careful monitoring due to potential side effects, mental health risks, and drug interactions.
Patients considering Austedo should work closely with their healthcare provider to determine if it is the right option for their specific condition.
