Ambien CR

Generic name: zolpidem tartrate

What is Ambien CR?

Ambien CR is a sedative-hypnotic (sleep) medicine. Ambien CR is used in adults for the treatment of a sleep problem called insomnia. Symptoms of insomnia include:

  • trouble falling asleep
  • waking up often during the night

Ambien CR is not recommended for use in children under the age of 18 years.

Ambien CR is a federally controlled substance (C-IV) because it can be abused or lead to dependence. Keep Ambien CR in a safe place to prevent misuse and abuse. Selling or giving away Ambien CR may harm others, and is against the law. Tell your healthcare provider if you have ever abused or have been dependent on alcohol, prescription medicines or street drugs.

What is the most important information I should know about Ambien CR?

  • Do not take more Ambien CR than prescribed.
  • Do not take Ambien CR unless you are able to stay in bed a full night (7 to 8 hours) before you must be active again.
  • Take Ambien CR right before you get in bed, not sooner.

Ambien CR may cause serious side effects including complex sleep behaviors that have caused serious injury and death. After taking Ambien CR, you may get up out of bed while not being fully awake and do an activity that you do not know you are doing (complex sleep behaviors). The next morning, you may not remember that you did anything during the night. These activities may occur with Ambien CR whether or not you drink alcohol or take other medicines that make you sleepy. Reported activities include:

  • driving a car ("sleep-driving")
  • making and eating food
  • talking on the phone
  • having sex
  • sleep-walking

Stop taking Ambien CR and call your healthcare provider right away if you find out that you have done any of the above activities after taking Ambien CR.

You should not drive a car or do things that require clear thinking the day after you take Ambien CR.

Do not take Ambien CR if you:

  • have ever experienced a complex sleep behavior (such as driving a car, making and eating food, talking on the phone, or having sex while not being fully awake) after taking Ambien CR.
  • drank alcohol that evening or before bed.
  • take other medicines that can make you sleepy. Taking Ambien CR with other drugs can cause side effects. Talk to your healthcare provider about all of your medicines. Your healthcare provider will tell you if you can take Ambien CR with your other medicines.
  • cannot get a full night's sleep.

    Symptoms of a serious allergic reaction to zolpidem can include:
    • swelling of your face, lips, and throat that may cause difficulty breathing or swallowing

What should I tell my healthcare provider before taking Ambien CR?

Ambien CR may not be right for you. Before starting Ambien CR, tell your healthcare provider about all of your health conditions, including if you:

  • have a history of depression, mental illness, or suicidal thoughts

  • have kidney or liver disease
  • have a lung disease or breathing problems
  • are pregnant, planning to become pregnant. Talk to your healthcare provider about the risk to your unborn baby if you take Ambien CR.

  • are breastfeeding or plan to breastfeed. Ambien CR passes into your breast milk. Talk to your healthcare provider about the best way to feed your baby while you take Ambien CR.

Tell your healthcare provider about all of the medicines you take, including prescription and nonprescription medicines, vitamins and herbal supplements.

Medicines can interact with each other, sometimes causing serious side effects. Do not take Ambien CR with other medicines that can make you sleepy unless your healthcare provider tells you to.
