Deutetrabenazine is a medication that is used to decrease the frequency and severity of involuntary, uncontrollable muscle movements that are related to a condition known as Tardive Dyskinesia (TD). TD is associated with chronic use of certain medications, such as antipsychotics. Deutetrabenazine may also be used to treat abnormal involuntary movements associated with Huntington Disease.
Deutetrabenazine may help improve some or all of these symptoms.
For deutetrabenazine to work properly, it should be taken every day as prescribed by your healthcare provider. Missing doses of deutetrabenazine may increase your risk for a relapse in your symptoms.
With input from you, your health care provider will assess how long you will need to take the medicine. Do not stop taking deutetrabenazine or change your dose without talking to your healthcare provider first.
Are there specific concerns about deutetrabenazine and pregnancy?
If you are planning on becoming pregnant, notify your healthcare provider to best manage your medications. People living with TD who wish to become pregnant face important decisions. Currently, there are no well-controlled human studies of deutetrabenazine in pregnancy. However, increased rates of stillbirths and postnatal mortality were seen in animal studies. It is important to discuss the risk and benefits of treatment with your doctor and caregivers.
Caution is advised with breast-feeding since it is not known if deutetrabenazine passes into your breast milk. Talk to your doctor about the best way to feed your baby during treatment with deutetrabenazine.
What should I discuss with my healthcare provider before taking deutetrabenazine?
- Symptoms of your condition that bother you the most

- Medications you have taken in the past for your condition, whether they were effective or caused any adverse effects

The following medications may decrease the levels and effects of deutetrabenazine:
Using deutetrabenazine with antipsychotics, tricyclic antidepressants, certain heart medications, and antibiotics may increase the risk of developing irregular heart rhythms.
The risk of parkinsonism, neuroleptic malignant syndrome, and akathisia may be increased by concomitant use of deutetrabenazine and antipscyhotics.
How long does it take for deutetrabenazine to work?
It is very important to tell your doctor how you feel things are going during the first few weeks after you start taking deutetrabenazine. It may take several weeks to see big enough changes in your symptoms to decide if deutetrabenazine is the right medication for you.
