What happens when you cut a 12.5mg Ambien CR in half?

Cutting a 12.5 mg Ambien CR (controlled release) tablet in half can disrupt its controlled-release mechanism, potentially leading to an immediate release of the active ingredient, zolpidem. This may increase the risk of side effects, such as drowsiness or dizziness, and can affect the medication's effectiveness. It's important to consult a healthcare provider before altering the dosage or form of any medication.
