Medicine information
Uses & overview
Tetrabenazine is a prescription medicine used to help manage involuntary movements associated with certain neurological disorders, particularly chorea related to Huntington's disease, where approved. It belongs to a group of medicines known as vesicular monoamine transporter 2 (VMAT2) inhibitors. Tetrabenazine works by reducing the storage and release of certain neurotransmitters, including dopamine, which can help decrease excessive involuntary movements in appropriate patients.The suitability of Tetrabenazine depends on the patient's diagnosis, medical history, mental health, other medicines, and response to treatment. Medical supervision is essential because the medicine may cause drowsiness, fatigue, depression, and movement-related adverse effects. It can also increase the risk of suicidal thoughts in susceptible patients, so careful monitoring is important.
