How Long Does Lunesta Stay in Your System
Lunesta is a prescription medication that is used to treat insomnia. After taking Lunesta, it is important to know how long it will stay in your system. This information is crucial to avoid any potential side effects or interactions with other medications.
The amount of time that Lunesta stays in your system can vary based on several factors, including your age, weight, and overall health.
Generally, the half-life of Lunesta is around 6 hours. This means that half of the medication will be eliminated from your body in that time frame.
However, it can take up to 2 days for Lunesta to completely leave your system. This is because the medication is metabolized in the liver and eliminated from the body through the kidneys.

Factors Influencing Drug Clearance
When it comes to determining how long Lunesta stays in your system, several factors can influence the drug’s clearance. These factors can include age and metabolism, liver function, dosage, and frequency of use.
Age and Metabolism
