All FDA black box warnings are at the end of this fact sheet. Please review before taking this medication.
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.
Symptoms of TD include:
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.
Deutetrabenazine may cause drowsiness. Avoid activities that require alertness, such as driving a car or operating machinery until you learn how your body respond to it.
If you experience any sudden changes in mood, behaviors, thoughts, or feelings, consult with your doctor immediately.
Only your health care provider can determine the length of deutetrabenazine treatment that is right for you. Do not stop taking deutetrabenazine or change your dose without talking to your health care provider first.
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 when a closely related drug was administered 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.
Deutetrabenazine is usually taken twice daily, with food. Tablets should be swallowed whole; do not chew, crush or break.
Typically patients begin at 6 mg twice a day and dose may be increased weekly in increments of 6 mg per day to a maximum of 48 mg per day (given in 2 divided doses). If you are taking deutetrabenazine for Huntington’s disease, you may start at an even lower dose. Only your healthcare provider can determine the correct dose for you.
Use a calendar, pillbox, alarm clock, or cell phone alert to help you remember to take your medication. You may also ask a family member or a friend to remind you or check in with you to be sure you are taking your medication.
If you miss a dose of deutetrabenazine, take it as soon as you remember, unless it is closer to the time of your next dose. Discuss this with your healthcare provider. Do not double your next dose or take more than what is prescribed.
Avoid drinking alcohol or using illegal drugs while you are taking deutetrabenazine. They may decrease the benefits (e.g. worsen your condition) and increase adverse effects (e.g. sedation) of the medication. When taking deutetrabenazine for the first time, do not drive or operate dangerous machinery until you know how the medication affects you.
If an overdose occurs call your doctor or 911. You may need urgent medical care. You may also contact the poison control center at 1-800-222-1222.
A specific treatment to reverse the effects of deutetrabenazine does not exist.
Common side effects
The most common side effects of taking deutetrabenazine are inflammation of the nose and throat, fatigue, drowsiness (in Huntington’s disease patients), insomnia (in TD patients), diarrhea, and dry mouth.
Rare/serious side effects
Rare side effects may include slight shaking, stiffness, trouble moving, anxiety, depression, agitation, restlessness, constipation, urinary tract infection, and irregular heart rhythm.
To date, there are no known problems associated with long term use of deutetrabenazine. It is a safe and effective medication when used as directed.
Deutetrabenazine should not be taken with or within 2 weeks of taking monoamine oxidase inhibitors (MAOIs) or within 20 days of taking reserpine, as these medications can increase side effects and decrease the effectiveness of deutetrabenazine. MAOIs include phenelzine (Nardil®), tranylcypromine (Parnate®), isocarboxazid (Marplan®), and selegiline (Emsam®).
Deutetrabenazine should not be taken with tetrabenazine (Xenazine®) or yalbenazine (Ingrezza®).
The following medications may increase the levels and effects of deutetrabenazine:
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.
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.
Depression and suicidal thoughts in patients with Huntington's disease
Deutetrabenazine can increase the risk of depression and suicidal thoughts in patients with Huntington’s disease. You should consider balancing the risks of depression and suicidality with the clinical need for treatment. You are encouraged to report behaviors of concern to your health care provider. Caution is advised in treating patients with a history of depression or prior suicide attempts, which are increased in frequency in Huntington’s disease. Deutetrabenazine is contraindicated in patients with Huntington’s disease who are suicidal, and in patients with untreated or inadequately treated depression.
