Which statement about a controlled-release carbidopa-levodopa prescription requires further education?

• A. If I have trouble swallowing, I should not crush the CR tablet and should discuss alternatives with my provider.
• B. Sometimes I have trouble swallowing, so I crush it and put it in applesauce.
• C. I should crush CR tablets if I have trouble swallowing.
• D. Crushing the tablet does not affect its release.

Answer: (A)

Controlled-release formulations are meant to release medicine gradually over time. Crushing a controlled-release carbidopa-levodopa defeats that design, causing the drug to dump into the system all at once. That leads to higher peak levels, more side effects, and a shorter overall duration of effect. So if swallowing is an issue, you should not crush the CR tablet and should talk with your provider about safer alternatives, such as using an immediate-release form or another administration option. The idea that you can crush it without changing how it works isn’t correct, and insisting that crushing doesn’t affect release also isn’t accurate.
