The cause of TD and how INGREZZA® (valbenazine) capsules work
TD is associated with taking certain mental health medicines for 3 months or longer.
INGREZZA was specifically designed to treat TD
Though how it works isn’t fully understood, INGREZZA is thought to reduce dopamine signaling in the brain—while working directly in the region of the brain that causes the uncontrollable movements of TD.
- INGREZZA is believed to reduce extra dopamine signaling
- Dopamine is a chemical in the brain that helps control movement
- TD may be caused by too much dopamine signaling in the brain
INGREZZA is proven to help reduce the uncontrollable movements of TD
About 70% of patients taking INGREZZA 80 mg saw reduction in TD movements in as few as 6 weeks*
- This post-clinical study evaluation included 70 patients taking INGREZZA 80 mg, measuring uncontrollable movements before starting treatment and at 6 weeks of treatment.
*Patients had at least a 1-point reduction on an uncontrollable movement severity scale at 6 weeks vs before treatment.
Some patients saw results in just 2 weeks
For people who participated in the clinical study, INGREZZA provided continued reduction in uncontrollable movements through 48 weeks.
