Benefits of Zolpidem (Ambien) for Insomnia

Zolpidem is a hypnotic, prescribed for the short term treatment of insomnia, or difficulty in getting to sleep or staying asleep.

Insomnia is itself not an illness, but it can cause distress and potentially worsen some mental disorders such as mania.

Side Effects of Zolpidem (Ambien)

Please note that the following side effects include only some of the most common and somewhat less common but do not include rarer side effects; the list is not exhaustive. Many people taking Zolpidem (Ambien, Stilnoct) experience none of these side effects. Please consult a physician about any unusual symptoms.


Some of the more common side effects of Zolpidem (Ambien, Stilnoct) include:

  • drowsiness
  • dizziness
  • lightheadedness
  • difficulty with coordination
  • diarrhoea
  • nausea
  • vomiting
  • vertigo
  • headache
  • asthenia

Less Common

Some of the less common side effects of Zolpidem (Ambien, Stilnoct) include:

  • amnesia
  • tolerance
  • dependence
  • changes in behaviour and thinking

Zolpidem (Ambien) and Alcohol

The manufacturer recommends that alcohol never be consumed while under treatment with Zolpidem or other sleeping tablets.

Alcohol can significantly increase the side effects of Zolpidem or any other sleep medication.

Stopping Zolpidem (Ambien): Discontinuation Effects or Withdrawal Symptoms

It is best to consult a physician before discontinuing hypnotics. These medications can cause withdrawal symptoms even after only being used for a week or two, including unpleasant feelings. Other withdrawal symptoms, while very uncommon, include:

  • abdominal and muscle cramps
  • vomiting
  • sweating
  • shaking
  • seizures

In addition, discontinuing sleep medications may cause ‘rebound insomnia’. This means that a person may have more trouble sleeping the first few nights after the medicine is stopped than before starting the medicine. Rebound insomnia usually goes away on its own after 1 or 2 nights.

Should You Buy Zolpidem (Ambien) Online?

Particularly in the United States, many individuals choose to purchase medications online, either for reasons of cost savings, privacy, or both. Both brand-name Ambien and so-called ‘generic Ambien’ (i.e., Zolpidem Tartrate without the Ambien brand name) can sometimes be purchased at deep discounts (and sometimes without a prescription) in this way. Before undertaking any purchase of medications online, however — and certainly if you are contemplating doing so without a prior prescription — please consider the integrity of the supplier and the national and/or local laws which may apply where you live.
