UnderstandING how INGREZZA® (valbenazine) works

Actor portrayals

Some mental health medicines (antipsychotics) can cause abnormal dopamine signaling in the brain. This abnormal signaling can lead to uncontrollable body movements called tardive dyskinesia (TD).

Current research suggests that INGREZZA helps by correcting this abnormal dopamine signaling; however, how INGREZZA works to treat TD is not fully understood.


  1. Stage 1

    Dopamine is a chemical in the brain that helps control movement.

  2. Stage 2

    TD may be caused by too much dopamine signaling in the brain.

  3. Stage 3

    INGREZZA selectively and specifically targets VMAT2, a protein that aids in the release of dopamine…

  4. Stage 4

    …which is believed to reduce this abnormal dopamine signaling.


What makes INGREZZA different?


Unlike other TD medications, INGREZZA selectively and specifically targets a protein called VMAT2.* VMAT2 aids in the release of dopamine.

*Based on laboratory tests. This does not imply a treatment advantage.

Did you know?
TD is unlikely to get better on its own. So, it’s important to take control and talk to your healthcare provider about treatment.

People taking INGREZZA for TD can stay on their current dose of most mental health medicines.
