What is zolpidem?

Zolpidem is used in adults to treat insomnia.

The immediate-release forms are Ambien, Edluar, and Zolpimist, which are used to help you fall asleep. Intermezzo, is used to help you fall back to sleep if you wake up in the middle of the night and then have trouble sleeping. The extended-release form of zolpidem is Ambien CR which has a first layer that dissolves quickly to help you fall asleep, and a second layer that dissolves slowly to help you stay asleep.

Your doctor will determine which form of zolpidem is best for you.

Zolpidem belongs to a class of medications called sedative-hypnotics. It works by slowing activity in the brain to allow sleep.

Popular FAQ

Both Quviviq and Ambien are oral prescription medicines used to help with trouble sleeping (known as insomnia). Quviviq and Ambien CR are used for adults who have trouble getting to sleep or staying asleep, while Ambien is used to help with sleep onset due to a shorter duration of action. Continue reading

Most people who take Ambien feel sedated and fall asleep, as expected, but rarely, some people show the opposite effect and become aroused or are unable to fall asleep. Experts aren’t sure exactly why this happens, but some research has suggested that because Ambien affects the inhibitory neurotransmitter, GABA and inhibitory neurons, this allows excitatory neurons responsible for transmitting activity to re-awaken and become active again because the inhibitory neurons are “asleep”. Continue reading

If you have had trouble sleeping in the past, then chances are your doctor may have prescribed you Ambien. But is this sedative any better than counting sheep? And what are the dangers associated with long-term use? Continue reading

Ambien is not safe for long-term use and should only be prescribed for a maximum of 6 weeks, but ideally should only be used for less than that. But some people find they can’t sleep without Ambien or they develop a habit of using Ambien after using it for recreational reasons. But certain hazardous health and psychological effects may occur with long-term use. Continue reading

Ambien (zolpidem) is not a benzo (benzodiazepine), it is unique in its action and does not resemble benzodiazepines or barbiturates at all. But it does work similarly. Both benzodiazepines and Ambien are thought to enhance the effects of a specific neurotransmitter in the brain called GABA. However, Ambien only induces sleep whereas benzodiazepines also work as anticonvulsants and muscle relaxants. Continue reading

Even though Ambien (zolpidem) is not as habit-forming as benzodiazepines, it is still addictive. When Ambien was first discovered, scientists thought it unlikely to cause tolerance, dependence, or be misused like benzodiazepines. But they were wrong. Physical dependence on the drug can develop within a couple of weeks, even when it is used at the dosages recommended. Ambien should only be used for short periods to help with sleep (ideally no more than seven to ten days). If you've been taking Ambien for longer or taking higher dosages than recommended, you may struggle with medication withdrawal symptoms when you try to quit. Continue reading

While “sleep-tweeting” has not been reported as an adverse side effect with Ambien, unusual sleep-related behaviors are possible with the drugs in this popular class of sleeping medications. Continue reading
