Can Ingrezza (valbenazine) cause daytime drowsiness or sleepiness?
Yes. Ingrezza (valbenazine) can cause sleepiness in some people, which may show up as drowsiness during the day.
What other “daytime” effects might feel like drowsiness?
Some patients describe the effect more generally as sedation or feeling less alert. If you notice you’re falling asleep unintentionally, feeling unusually slow, or having trouble staying awake, that can be consistent with a sedating side effect.
Who is more likely to feel drowsy on Ingrezza?
The risk of drowsiness tends to be higher if you also take other medicines that cause sedation. Combining Ingrezza with other drugs that can make you sleepy (for example, certain anxiety medicines, sleep medicines, opioids, or some allergy medicines) can increase daytime impairment.
What should you do if you feel drowsy while taking Ingrezza?
If you experience daytime drowsiness, talk with your prescriber about adjusting the dose or timing. Avoid driving or operating machinery if you feel sleepy. If drowsiness is severe or getting worse, contact your clinician promptly.
When to get urgent help
Seek urgent medical care if sleepiness comes with serious symptoms like fainting, trouble breathing, confusion, or inability to stay awake.
