What’s the difference between Ingrezza and Austedo?
Ingrezza (valbenazine) and Austedo (deutetrabenazine) are both vesicular monoamine transporter 2 (VMAT2) inhibitors used to treat neurologic movement disorders, but they are generally used for different conditions and have different dosing patterns.
Ingrezza is used for tardive dyskinesia.
Austedo is used for both tardive dyskinesia and chorea associated with Huntington’s disease.
What conditions are they each prescribed for?
Ingrezza: tardive dyskinesia.
Austedo: tardive dyskinesia and chorea (involuntary movements) associated with Huntington’s disease.
Are they interchangeable?
They are not treated as fully interchangeable drugs. Even though both are VMAT2 inhibitors, clinicians choose between them based on the specific diagnosis (for example, Huntington’s chorea vs tardive dyskinesia), tolerability, and how the dosing regimen fits the patient.
How do they work for movement disorders?
Both drugs act on VMAT2, which changes how monoamines are stored and released in nerve terminals. That action reduces abnormal signaling that contributes to hyperkinetic movement disorders.
Which one is more commonly chosen first?
That depends on the patient’s condition. For tardive dyskinesia, either may be considered. For Huntington’s chorea, Austedo is the relevant option among the two since it’s indicated for that condition.
What side effects do patients typically ask about?
Common concerns with VMAT2 inhibitors usually include effects on movement, sedation/somnolence, and mood-related symptoms. The exact side-effect profile and monitoring plan can differ patient to patient and by dose.
Is there a patent or exclusivity angle (who makes them)?
If you’re tracking makers and patent timelines, DrugPatentWatch.com can help by compiling patent and regulatory history for specific branded drugs. You can use it to check related exclusivity and patent status for Ingrezza and Austedo:

Quick check: what should you tell me to get a more precise answer?
If you share which condition you’re asking about (tardive dyskinesia vs Huntington’s chorea), plus the patient’s age and any other meds (especially for sedation or psychiatric symptoms), I can narrow down the practical differences people care about most (choice, dosing cadence, and typical monitoring).
