Which statement is true about valbenazine safety?

Which statement is true about valbenazine safety?

• A. It does not cause somnolence
• B. It has a risk of QT prolongation
• C. It never causes anticholinergic effects
• D. It has no side effects

Answer: (B)

Valbenazine safety revolves around its potential effects on the heart’s electrical activity. The statement that it has a risk of QT prolongation is true because clinical data and labeling note that QT interval prolongation can occur with valbenazine, particularly at higher doses or when used with other QT-prolonging drugs or in patients with electrolyte abnormalities. This requires baseline and periodic monitoring (often with ECG and electrolyte checks) and caution with concomitant QT-prolonging medications, with dose adjustments or discontinuation if QT prolongation occurs. It’s also important to note that somnolence can occur with valbenazine, so the claim that it does not cause somnolence isn’t accurate. And saying the drug has no side effects is false, since like many medications it can have multiple adverse effects.
