What is Austedo Xr Patient Titration Kit?

Deutetrabenazine is used in adults to treat involuntary muscle movements (chorea) caused by Huntington's disease. Deutetrabenazine is not a cure for Huntington's disease and will not treat other symptoms of this condition.

Deutetrabenazine 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).

Deutetrabenazine may also be used for purposes not listed in this medication guide.

Warnings

You should not use deutetrabenazine 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
  • liver disease.

Do not use deutetrabenazine 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, anger, 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 deutetrabenazine may further increase this risk. However, the benefits of taking this medicine (improvement in daily living) may outweigh any suicidal risks.

Taking deutetrabenazine 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 use Austedo Xr Patient Titration Kit

Use Austedo Xr Patient Titration Kit (Oral) exactly as directed on the label, or as prescribed by your doctor. Do not use in larger or smaller amounts or for longer than recommended.

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.

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

Deutetrabenazine 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).

Some tablets are made with a shell that is not absorbed or melted in the body. Part of this shell may appear in your stool. This is normal and will not make the medicine less effective.

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

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

What should I do if I missed a dose of Austedo Xr Patient Titration Kit (Oral)?

Take the medicine as soon as you can, but skip the missed dose if it is almost time for your next dose. Do not take two doses at one time.
