What is Austedo XR?
Austedo XR is used in adults to treat involuntary muscle movements (chorea) caused by Huntington's disease. This medicine is not a cure for Huntington's disease and will not treat other symptoms of this condition.
Austedo XR is also used in adults to treat symptoms of tardive dyskinesia, a nervous system disorder. Tardive dyskinesia causes repetitive uncontrolled muscle movements, usually in the face (chewing, lip smacking, frowning, tongue movement, blinking or eye movement).
Austedo XR is not a permanent cure for involuntary movement disorders.
Austedo XR may also be used for purposes not listed in this medication guide.

Before taking this medicine
You should not use Austedo XR if you are allergic to it, or if you have:
-
untreated or uncontrolled depression;
-
thoughts about suicide or hurting yourself;
-
if you have recently taken tetrabenazine or valbenazine; or
Do not use Austedo XR 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.
Tell your doctor if you have or have ever had:
-
depression, anxiety, nervousness, or agitation;

mental illness or psychosis;

suicidal thoughts or actions;
-
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 Austedo XR may further increase this risk. However, the benefits of taking Austedo XR (improvement in daily living) may outweigh any suicidal risks.
Taking Austedo XR 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 Austedo XR?
Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your dose. Use the medicine exactly as directed.

Austedo XR is usually taken 1 or 2 times per day with or without 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 XR for longer than 1 week, do not start taking it again without your doctor's advice.
