How does Ambien work?

Ambien is a prescription medication approved by the Food and Drug Administration (FDA) to treat insomnia — a sleep disorder that makes it difficult to fall or stay asleep.

Ambien belongs to a class of medications called sedative hypnotics. These depress the central nervous system to promote relaxation and induce sleep.

Ambien is available in a generic form in the United States as zolpidem. Other U.S. brand names for zolpidem include Intermezzo and Edluar.

You typically take Ambien as needed to help initiate sleep rather than as a daily maintenance insomnia medication. But it’s important to follow your healthcare professional’s instructions regarding the dosing schedule and the duration of treatment.

What does Ambien do to your body?

Ambien acts on a specific receptor in the brain known as the GABA-A receptor. GABA is a neurotransmitter (messenger between nerve cells) that helps manage how alert or calm your brain cells are.

When Ambien binds to the GABA-A receptor in the cell, it enhances the natural effects of GABA, inhibiting certain brain activities.

This process helps calm the central nervous system and promote overall relaxation, leading to faster sleep onset and improved sleep quality in people with insomnia.

Uses of Ambien

Zolpidem (Ambien) is FDA-approved for:

• Insomnia: Treatment of short-term insomnia by reducing the time it takes to fall asleep and increasing sleep duration.
• Middle-of-the-night awakening: Ambien CR (controlled release) is approved for people who experience awakening in the middle of the night and have difficulty returning to sleep.

Aside from its FDA-approved uses, healthcare professionals may sometimes prescribe Ambien off label. Off-label means using a medication for a medical purpose different from an FDA-approved one.

These off-label uses are based on medical judgment and supported scientific evidence.

Some potential off-label uses of Ambien include:

• Anxiety-related insomnia: Sometimes, a doctor may prescribe Ambien off-label to treat insomnia caused by anxiety disorders.
• Shift work sleep disorder: A doctor may prescribe Ambien to help people with shift work sleep disorder, where sleep is disrupted due to irregular shifts.
• Jet lag: Ambien might also be used off-label to alleviate the sleep disturbances associated with jet lag when adjusting to a new time zone.

How long does Ambien take to work?

The time it takes for Ambien to start working may vary depending on the formulation:

• Immediate-release tablets begin working within 15–30 minutes to help you fall asleep faster.
• Extended-release tablets have two layers that work in stages. The first layer helps you fall asleep fast by dissolving quickly, while the second layer dissolves slowly to help you stay asleep all night. Initiating sleep may take longer than the immediate-release form. 

The therapeutic effects of Ambien typically last for about 7–8 hours.

A healthcare professional will determine how long you need to take Ambien because the safety and effectiveness of long-term use may differ based on various factors. 

Most doctors may recommend using Ambien for a short duration because taking it for a long time may lead to habit formation and increase the risk of developing dependence or addiction.

What does being on Ambien feel like?

Being on Ambien may lead you to feel relaxed but also drowsy. Zolpidem makes you feel calm and less anxious, which can help you fall asleep. Some people may also experience a mild euphoria or a dream-like state when taking the medication.

When Ambien starts working, you may notice several effects, including:

• Drowsiness and sleepiness: Ambien may make you feel drowsy. This drowsiness is often one of the first signs that the medication is taking effect.
• Reduced anxiety: Ambien’s sedative effects may help calm your mind and alleviate physical signs of anxiety or restlessness that may have prevented you from falling asleep. 
• Improved sleep onset: You may fall asleep faster than before taking the medication.

As with any medication, Ambien may lead to some side effects, including:

• dizziness
• headaches
• nausea
• dry mouth
• confusion

Do melatonin supplements act as Ambien?

Melatonin supplements are different from Ambien. While both help with sleep, they have different mechanisms of action in your brain.

You can find melatonin as an over-the-counter product. Melatonin supplements generally support the body’s natural sleep-wake cycle.

They can help with short-term sleep disruptions, particularly for people with jet lag or shift-work sleep disorder. You may still have difficulty falling or staying asleep with melatonin if you live with insomnia.

Ambien is a prescription medication for the short-term treatment of insomnia. It directly affects brain receptors to induce sleepiness and promote deep sleep. 

Alternative meds

Alternative medications for insomnia may include:

• eszopiclone (Lunesta): A sedative hypnotic medication that is FDA-approved for treating insomnia.
• zaleplon (Sonata): A sedative medication used for short-term treatments.
• ramelteon (Rozerem): A melatonin receptor agonist that regulates the sleep-wake cycle.
• doxepin (Silenor): A tricyclic antidepressant medication approved by the FDA at lower doses for the treatment of insomnia.

Summary

Ambien is an FDA-approved medication to treat insomnia. It works by enhancing the activity of the neurotransmitter GABA in the brain, leading to a calming effect that helps in falling asleep. 

Take Ambien under the guidance of a healthcare professional and for short-term treatment only due to its potential for dependence and other side effects.
