About Valbenazine

Valbenazine is a VMAT2 inhibitor; the label says its exact mechanism is unclear but is thought to involve reversibly blocking VMAT2, a transporter nerve cells use to store dopamine. The label approves it for adults with tardive dyskinesia and for adults with chorea associated with Huntington’s disease; it is not established in children. It starts at 40 mg once a day. For tardive dyskinesia the dose rises to the recommended 80 mg after one week; for Huntington’s chorea it rises by 20 mg every two weeks to 80 mg. A dose of 40 mg or 60 mg may be kept based on response and tolerability. The dose stays at 40 mg with moderate or severe liver impairment, in known CYP2D6 poor metabolizers, and with a strong CYP3A4 or CYP2D6 inhibitor.

The boxed warning says VMAT2 inhibitors can increase the risk of depression and suicidal thoughts and behavior in people with Huntington’s disease, so patients and families watch for new or worsening depression or unusual behavior and report it promptly. The only contraindication is allergy to valbenazine or an ingredient. Warnings cover angioedema (throat swelling can be fatal), sleepiness, QT prolongation (it is avoided with congenital long QT syndrome), neuroleptic malignant syndrome, and parkinsonism, sometimes severe, mostly in the first two weeks after starting or raising the dose. Common side effects include sleepiness, tiredness, falls, headache, restlessness and nausea, and, in Huntington’s disease, hives and rash.

What is distinctive is the choice of capsule. Regular Ingrezza capsules are swallowed whole; Ingrezza Sprinkle capsules can be swallowed whole or opened over soft food, but are not crushed or chewed (or given through a feeding tube). It is not taken within 14 days of an MAO inhibitor. The label advises not breastfeeding during treatment and for 5 days after the last dose. The label was revised in April 2026, and each fill comes with a Medication Guide. It is not a controlled substance.

Taking Valbenazine

How to take it

Take it once a day, with or without food. Swallow regular capsules whole. Sprinkle capsules can be swallowed whole or opened over a tablespoon of applesauce, yogurt or pudding (not milk or water), swallowed right away, then followed by a glass of water.

If you miss a dose

Take the missed dose as soon as you remember, unless it is almost time for the next one; then skip it and continue your usual schedule. Do not take a double dose.

Storage

Keep it tightly closed in the original container at room temperature, away from moisture and out of reach of children. Throw away a Sprinkle and food mixture not taken within 2 hours.

Interactions to know about

Do not take it within 14 days of an MAO inhibitor. Strong CYP3A4 or CYP2D6 inhibitors call for a lower dose, strong CYP3A4 inducers are not recommended, and it raises digoxin levels. Do not drink alcohol, which adds to drowsiness; ask about grapefruit juice and St. John’s wort.

This summarizes the official prescribing information. Your prescriber’s and pharmacist’s instructions, and the leaflet that comes with your medicine, take priority.

Why the cash price for Valbenazine differs from pharmacy to pharmacy

Valbenazine is sold only as the Ingrezza brand, so every quote is priced as a brand and differences come from how each pharmacy buys and prices it. The maker says many pharmacies nationwide have access to it and also names specialty pharmacies that deliver, so some pharmacies stock it and others order it in.

Regular capsules, Sprinkle capsules and the initiation packs are separate products, so quotes are only comparable for the same form, strength and package. The dispensing fee is a small share of a brand quote.

Ways to pay less for Valbenazine without insurance

• Ask the maker whether its savings or patient assistance program applies to someone paying cash; many copay programs require commercial insurance.
• Compare more than one pharmacy for the exact form and strength prescribed, and call ahead, since some order it in.
• Once the dose is settled, ask the prescriber whether a ninety-day supply is appropriate.
• Ask the prescriber whether regular or Sprinkle capsules suit you, since the pharmacy fills the one named.
• Upload the prescription to Script Unlock so licensed pharmacies can quote their cash price. You pay the pharmacy directly.
