What is Deutetrabenazine?
Simply put, deutetrabenazine is a prescription medicine that helps control involuntary, unwanted muscle movements in your body. Doctors mainly prescribe this medicine for two specific medical conditions:
1. Tardive Dyskinesia: This condition can happen if you take certain mental health medicines for a long time. It causes uncontrolled movements in your face, lips, tongue, trunk, or limbs.
2. Huntington's Disease: Also called Huntington's chorea, this is an inherited condition that affects the brain. It causes jerky, uncontrolled movements throughout your body.
Deutetrabenazine works by changing how certain natural chemicals, called neurotransmitters, act in your brain. This helps quiet the signals that cause unwanted movements. In some regions, you might find this medicine under the brand name Austedo.
