Healing From Sleeping Pill Addiction: Why Dependence Happens and How Recovery Works

Begin Recovery

Prescription sleep medications most commonly associated with dependency include Z-drugs (Ambien, Lunesta, Sonata), as well as older sedatives called barbiturates. OTC sleep medications have less potential for abuse but may still pose some risk with prolonged use.

Ambien increases GABA levels in the brain. With regular use, the brain begins to adapt by adjusting GABA production. As a result, tolerance develops, and withdrawal symptoms appear when attempting to stop. Many people who begin using Ambien for occasional difficulty sleeping become physically dependent on the drug.

It typically takes no longer than two weeks of nightly use — even at recommended dosages — for dependence to develop. Because of these risks, many medical professionals limit Z-drug prescriptions to short-term use.

Common indicators include taking higher amounts than recommended, hiding how much Ambien is being used, daytime fatigue, amnesia, sleepwalking, and extreme mood swings while under the influence. People who experience anxiety when the effects wear off, feel extremely irritable upon waking, or experience rebound insomnia when attempting to quit may also be showing signs of dependency.

Over-the-counter sleeping pill addiction is less common than with prescription medications, but psychological dependence and tolerance can develop with sustained daily use of products containing diphenhydramine or doxylamine. These products also carry their own health risks, particularly in older adults.
