• If Ambien is used daily for more than a few weeks, abrupt discontinuation is not recommended or you could have unpleasant
withdrawal symptoms. Ask your doctor how to avoid
withdrawal symptoms when you stop using the medicine.
• Immediate-release Ambien is used to help you fall asleep. The extended-release form, Ambien CR, has a first layer that dissolves quickly to help you fall asleep, and a second layer that dissolves slowly to help you stay asleep.
