Depression and Suicidality in Patients with Huntington's DiseaseDeutetrabenazine can increase the risk of depression and suicidal thoughts and behavior (suicidality) in patients with Huntington disease. Anyone considering the use of deutetrabenazine must balance the risks of depression and suicidality with the clinical need for treatment of chorea. Closely monitor patients for the emergence or worsening of depression, suicidality, or unusual changes in behavior. Patients, their caregivers, and families should be informed of the risk of depression and suicidality and should be instructed to report behaviors of concern promptly to the treating physician.Particular caution should be exercised in treating patients with a history of depression or prior suicide attempts or ideation, which are increased in frequency in Huntington’s disease. Deutetrabenazine is contraindicated in patients who are suicidal, and in patients with untreated or inadequately treated depression .

Precautions while using deutetrabenazine
It is very important that your doctor check your progress at regular visits to see if the medicine is working properly and to allow for changes in the dose.
Deutetrabenazine may cause some people to be agitated, irritable, or display other abnormal behaviors. It may also cause some people to have suicidal thoughts and tendencies or to become more depressed, especially if they have a condition called Huntington's disease. If you or your caregiver notice any of these side effects, tell your doctor right away.
Do not take deutetrabenazine if you are also taking a monoamine oxidase (MAO) inhibitor such as isocarboxazid (Marplan®), phenelzine (Nardil®), selegiline (Eldepryl®), or tranylcypromine (Parnate®) within 14 days of each other. If you have questions, check with your doctor.
Do not take deutetrabenazine if you are also taking reserpine (Serpalan® or Renese®-R). Wait at least 20 days after stopping reserpine before starting deutetrabenazine. If you have questions, check with your doctor.
Do not take deutetrabenazine if you are also taking tetrabenazine (Xenazine®) or valbenazine (Ingrezza®). Take deutetrabenazine one day after stopping tetrabenazine. If you have questions, check with your doctor.
Contact your doctor right away if you have any changes to your heart rhythm. You might feel dizzy or faint, or you might have a fast, pounding, or uneven heartbeat. Make sure your doctor knows if you had a heart rhythm problem, such as QT prolongation.
Check with your doctor right away if you have any of the following symptoms while using deutetrabenazine: convulsions (seizures), difficulty with breathing, a fast heartbeat, a high fever, high or low blood pressure, increased sweating, loss of bladder control, severe muscle stiffness, unusually pale skin, or tiredness. These could be symptoms of a serious condition called neuroleptic malignant syndrome (NMS).
Check with your doctor right away if you have an inability to sit still, need to keep moving, or restlessness. These could be symptoms of a movement disorder called akathisia.
Deutetrabenazine may cause parkinsonism (a movement disorder). Check with your doctor right away if you have difficulty swallowing, loss of balance control, mask-like face, shuffling walk, slowed movements, slurred speech, stiffness of the arms and legs, tic-like or jerky movements of the head, face, mouth, and neck, or trembling and shaking of the fingers and hands.
Deutetrabenazine may cause drowsiness, trouble with thinking, or trouble with controlling movements. Do not drive or do anything else that could be dangerous until you know how deutetrabenazine affects you.
Make sure your doctor knows if you are using amiodarone (Cordarone®), chlorpromazine (Thorazine®), moxifloxacin (Avelox®), procainamide (Pronestyl®), quinidine, sotalol (Betapase®), thioridazine (Mellaril®), or ziprasidone (Geodon®). Using any of these medicines together with deutetrabenazine may cause serious side effects.
Dizziness, lightheadedness, or fainting may occur, especially when you get up from a lying or sitting position. Getting up slowly may help. If the problem continues or worsens, check with your doctor.
Deutetrabenazine will add to the effects of alcohol and other central nervous system (CNS) depressants. CNS depressants are medicines that slow down the nervous system, which may cause drowsiness or make you less alert. Some examples of CNS depressants are antihistamines or medicine for hay fever, allergies, or colds, sedatives, tranquilizers, or sleeping medicine, prescription pain medicine or narcotics, barbiturates or medicine for seizures, muscle relaxants, or anesthetics (numbing medicines), including some dental anesthetics. This effect may last for a few days after you stop taking deutetrabenazine. Check with your doctor before taking any of the above while you are using deutetrabenazine.
