How long may tremor improvement take after starting benztropine?

• A. Within hours
• B. Several weeks
• C. Immediately
• D. Never

Answer: (B)

Benztropine helps tremor by reducing excess cholinergic activity in the basal ganglia, helping to rebalance motor control. That adjustment of neurotransmitter balance and the brain’s neural circuits doesn’t happen instantly. As the dose is started and sometimes slowly increased, improvement in tremor tends to unfold over time. For many patients, noticeable tremor reduction emerges after several weeks, with full effect often evident after a month or more. If there’s no meaningful benefit after a few weeks of therapy, clinicians reassess the plan.
