Ambien CR Precautions
The FDA (U.S. Food and Drug Administration) lowered the recommended Ambien CR dose for women from 12.5 mg to 6.25 mg on January 10, 2013 because new data show that blood levels in some patients may be high enough the morning after use to impair activities that require alertness, including driving. Women appear to be more susceptible to this risk because they eliminate Ambien CR from their bodies more slowly than men.
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. The next morning, you may not remember that you did anything during the night. You should be aware that impairment from sleep drugs can be present despite feeling fully awake. You have a higher chance for doing these activities if you drink alcohol or take other medicines that make you sleepy with Ambien CR.
Reported activities include:
- driving a car ("sleep-driving")
- making and eating food
- talking on the phone
- having sex
Call your doctor right away if you find out that you have done any of the above activities after taking Ambien CR.
- Take Ambien CR right before you get in bed, not sooner.
- Do not take Ambien CR if you drink alcohol.
- Do not take Ambien CR with other medicines that can make you sleepy.
- Do not take Ambien CR if you cannot get a full night's sleep or stay in bed 7 or 8 hours before being active again.
- Do not take Ambien CR if you are allergic to anything in it. Severe allergic reactions have occurred with Ambien CR use. Seek emergency medical attention if you have unexplained rash, itching, hives, wheezing or trouble breathing, or unexplained swelling (especially of the throat, lips, or mouth).
Ambien CR can cause dizziness or drowsiness. Do not drive or operate heavy machinery until you know how Ambien affects you.
Ambien CR Food Interactions
Medicines can interact with certain foods. In some cases, this may be harmful and your doctor may advise you to avoid certain foods. In the case of Ambien CR there are no specific foods that you must exclude from your diet when receiving Ambien CR.

Ambien CR and Pregnancy
Tell your doctor if you are pregnant or plan to become pregnant.
The FDA categorizes medications based on safety for use during pregnancy. Five categories - A, B, C, D, and X, are used to classify the possible risks to an unborn baby when a medication is taken during pregnancy.
This medication falls into category C. In animal studies, pregnant animals were given this medication and had some babies born with problems. No well-controlled studies have been done in humans. Therefore, this medication may be used if the potential benefits to the mother outweigh the potential risks to the unborn child.
