What is Austedo?

Austedo (deutetrabenazine) is a prescription medicine used to treat chorea associated with Huntington's disease and tardive dyskinesia (TD), which are involuntary movement disorders. Austedo helps reduce uncontrolled movements and improve the quality of life for patients; however, it does not cure the underlying condition causing the movement disorder. 

Austedo works by regulating the storage and release of natural chemical messengers (neurotransmitters) from nerves, to help control symptoms such as twitching, jerking, or facial tics. It does this by targeting and blocking a protein in the brain called VMAT2, which is responsible for moving neurotransmitters (chemical messengers) into nerve cell storage areas.

Austedo's drug class is a VMAT2 inhibitor (vesicular monoamine transporter 2 inhibitor).

Austedo tablets are taken twice daily, and the Austedo XR (extended-release) tablets are taken once daily.

What is Tardive dyskinesia (TD) and chorea associated with Huntington’s disease 

Tardive dyskinesia (TD) is a nervous system disorder that causes repetitive, uncontrolled muscle movements, usually in the face (chewing, lip smacking, frowning, tongue movement, blinking, or eye movement). Tardive dyskinesia can develop due to using certain medicines.

Chorea associated with Huntington's disease is sudden, involuntary movements usually of the arms, legs, face, and tongue. It is an inherited disease that causes the progressive breakdown of nerve cells in the brain. Austedo is not a cure for Huntington's disease and will only treat the symptom of chorea; it does not treat other symptoms of this condition.

Austedo side effects

Common Austedo side effects may include:

• drowsiness;
• tiredness;
• dry mouth;
• runny or stuffy nose, sore throat;
• sleep problems (insomnia); or
• diarrhea.

Serious Austedo side effects

Get emergency medical help if you have signs of an allergic reaction to Austedo: hives; difficult breathing; swelling of your face, lips, tongue, or throat.

Some people have thoughts about suicide while taking Austedo for Huntington's disease. Stay alert to changes in your mood or symptoms. Your family or caregivers should also watch for sudden changes in your behavior.

Some side effects may actually be signs that your Huntington's disease is progressing. Your doctor will need to check your progress on a regular basis.

Deutetrabenazine may cause other serious side effects. Call your doctor at once if you have:

• fast or pounding heartbeats, fluttering in your chest, shortness of breath, and sudden dizziness (like you might pass out);
• severe restlessness or agitation;
• tremors, shaking;
• muscle stiffness;
• problems with balance or coordination; or
• severe nervous system reaction - very stiff (rigid) muscles, high fever, sweating, confusion, fast or uneven heartbeats, tremors, feeling like you might pass out.

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.

Warnings 

QTc Prolongation. This medicine may prolong the QT interval, but the degree of QT prolongation is not clinically significant when administered within the recommended dosage range.  Austedo tablets and XR tablets should be avoided in patients with congenital long QT syndrome and in patients with a history of cardiac arrhythmias associated with a prolonged QT interval. 

Certain circumstances may increase the risk of the occurrence of torsade de pointes and/or sudden death in association with the use of drugs that prolong the QTc interval, including: 

• slow heart rate (bradycardia),
• low potassium levels (hypokalemia), 
• low magnesium blood levels (hypomagnesemia), 
• having a congenital prolongation of the QT interval, and
• concomitant use of other drugs that prolong the QTc interval.

Depression and Suicide. Some people have thoughts about suicide while taking Austedo tablets and extended-release tablets; stay alert to changes in your mood, feelings, thoughts, or behaviors. Tell your doctor right away if you have any sudden changes in mood or behavior or thoughts about suicide.

You should not use this medicine if you have Huntington’s disease and you have untreated or uncontrolled depression, or if you have thoughts about suicide.

Other medicines. Do not use this medicine if you have taken reserpine (Serpalan, Renese-R) in the past 20 days, or if you have used an MAO inhibitor (isocarboxazid, linezolid, rasagiline, selegiline, and others) in the past 14 days. See the Interactions section for more interactions with this medicine.

Before taking this medicine

You should not use Austedo if you are allergic to the active ingredient, deutetrabenazine, inactive ingredients, or if you have:

• untreated or uncontrolled depression;
• thoughts about suicide or hurting yourself;
• if you have recently taken tetrabenazine or valbenazine; or
• liver impairment.

Do not use this medicine if you have taken reserpine 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, and tranylcypromine.

To make sure this medicine is safe for you, tell your doctor if you have ever had:

• depression, anxiety, nervousness, or agitation;
• mental illness or psychosis;
• suicidal thoughts or actions;
• breast cancer;
• a heart rhythm disorder;
• long QT syndrome (in you or a family member);
• an electrolyte imbalance (such as low blood levels of potassium or magnesium); or
• liver disease.

People with Huntington's disease may have a higher risk of depression and suicidal thoughts or behaviors. Taking this medicine may further increase this risk. However, the benefits of taking this medicine (improvement in daily living) may outweigh any suicidal risks.

Taking this medicine may cause symptoms similar to Parkinson's disease (resting tremor, stiff muscles, slow movements, difficulty maintaining balance, and walking). Ask your doctor about your risk.

Your doctor will need to check your progress on a regular basis. Your family or caregivers should also watch for sudden changes in your behavior.

Tell your doctor if you are pregnant or breastfeeding.

How should I take this medicine?

Take Austedo as prescribed by your doctor. Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your dose.

If you are switching from a similar medicine called tetrabenazine, take your first dose of Austedo one day after your last dose of tetrabenazine.

Austedo tablets are usually taken twice daily with food and a whole glass of water. Swallow the tablet whole and do not crush, chew, or break it. Tell your doctor if you have trouble swallowing the tablet whole.

You may need medical tests to check your heart function using an electrocardiograph or ECG (sometimes called an EKG).

Do not stop the medicine without your doctor's advice. If you stop taking Austedo for longer than 1 week, do not start taking it again without your doctor's advice.

Store at room temperature away from moisture and heat. Keep the medicine in the original container, along with the packet or canister of moisture-absorbing preservative.
