Ambien Drug Dependence

Ambien medication has a high risk of dependency. There is usually a psychological and physical dependence to this drug. Psychologically, you may feel that you need this medication to help you sleep at night, and if you don't take it, you will have insomnia. This creates a self-fulfilling prophecy that means if you think you can't sleep, you won't be able to. Ambien creates a physical dependency as well because your body builds up a tolerance, and you will have to take more to achieve the same benefits from it. In addition, if you decide to lower your dose or discontinue the drug, your body will go through withdrawal symptoms making you believe you need to take it to feel normal.

Avoiding Ambien Adverse Reactions

The best way to avoid Ambien adverse reactions is to use the medication as needed. If you experience insomnia or have trouble falling asleep occasionally, you should only use it during times you absolutely need it. This will cut down on side effects because your body will usually react to a drug if it has been in your system for a few days. If you have chronic insomnia and need to take Ambien regularly, only take the dosage your doctor recommends. Taking low doses of the drug will lower your risk for dependency as well as adverse side effects. If this low dose does not work as well as it did when you first started, speak to your doctor before increasing your dosage.

Trying Other Sleep Medications

If you have been addicted to drugs before or have a dependency on Ambien, you may want to talk to your doctor about taking another type of sleep medication. Sleep medications are widely available on the market today and some do not have the addictive qualities this one has or the risk of serious side effects.


When taking addictive medication, pay attention to your reaction to it. It's better to be cautious than to let yourself get in trouble. Let a friend or family member help you by letting him or her know you are starting this medication. Your loved one can let you know if he or she notices anything out of the ordinary, so you can contact your doctor.
