How quickly does Ingrezza (valbenazine) start working?
Ingrezza (valbenazine) works over days to weeks. Many people notice changes in involuntary movements during the first few weeks of treatment, with more complete effects typically seen with continued use over longer follow-up.
When should you expect noticeable improvement?
Clinicians and patients generally look for an early signal of benefit within the first couple of weeks, then continued improvement as treatment continues. If you do not notice any benefit after several weeks, your prescriber may reassess the dose and whether Ingrezza is the right fit.
How long until the “full effect”?
The full effect is usually assessed after several weeks of therapy, when the medication has had time to reach and sustain its expected impact on symptoms. Switching to a different dose or medication may be considered if response is inadequate.
What factors can change how fast it works?
How quickly Ingrezza works can vary by person and may depend on factors like the condition being treated (tardive dyskinesia vs. other approved uses), your dose, and how consistently you take it.
When to contact a doctor
Talk with your prescriber sooner if symptoms worsen, you develop concerning side effects, or you feel no improvement after an adequate trial at the prescribed dose.
