Ambien CR

Generic Name: Zolpidem

  • What is this medication and its most common uses?

    Ambien CR is a medicine used for the treatment of insomnia, specifically for people who have trouble falling asleep and/or wake up often during the night.

    Ambien CR is a federally controlled substance because it has abuse potential.

  • What should I know when beginning and continuing on this medication?

    How does this medication work?

    Ambien CR is an extended-release medicine (a type of tablet that releases medicine into your body throughout the night). It works by decreasing the time it takes you to fall asleep and the number of awakenings you have during the night, thereby increasing your time asleep.

    What are the beneficial effects of this medication and when should I begin to have results?

    What: Ambien CR may help you fall asleep faster and stay asleep throughout the night.

    When: For most patients, Ambien CR acts quickly and therefore should be taken right before you get into bed and only if you have 7-8 hours to devote to sleep. It is important that you take Ambien CR exactly as your healthcare provider has prescribed. If your insomnia gets worse or is not better within 7 to 10 days, call your healthcare provider as this may mean that there is another condition causing your sleep problems.

    How do I know it is working?

    If you are able to fall asleep faster than you normally would and do not wake up as often during the night, Ambien CR is likely working effectively. Your healthcare provider may ask you questions from time to time to assess your sleep pattern.
