Valbenazine anticholinergic adverse effects occur in which approximate frequency range?

Valbenazine anticholinergic adverse effects occur in which approximate frequency range?

• A. 0-1%
• B. 2.7-5.4%
• C. 10-15%
• D. 20-30%

Answer: (B)

Understanding how adverse-event frequencies are reported helps you interpret these questions. In clinical trials, side effects are given as the percentage of patients who experience them. For valbenazine, anticholinergic-type symptoms (such as dry mouth or constipation) occurred in only a small portion of patients. The data show these events in roughly 2.7–5.4% of participants. That places them in the low-but-not-rare range, not in the very common or the very rare extremes. So the 2.7–5.4% range best matches the observed frequency, which is why it’s the correct pick.
