Brand Name(s):

WHY is this medicine prescribed?
Estazolam is used for the short-term treatment of insomnia (difficulty falling asleep or staying asleep). Estazolam is in a class of medications called benzodiazepines. It works by slowing activity in the brain to allow sleep.

HOW should this medicine be used?
Estazolam comes as a tablet to take by mouth. It is usually taken as needed at bedtime or after going to bed and having difficulty falling asleep. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take estazolam exactly as directed.

You will probably become very sleepy after you take estazolam and may remain sleepy for some time. Plan to go to bed right after you take estazolam and to stay in bed for a full night. Do not take estazolam if you will be unable to remain asleep for a full night after you take the medication.

Your sleep problems should improve within 7 to 10 days after you start taking estazolam. Call your doctor if your sleep problems do not improve during this time, if they worsen at any time during your treatment, or if you notice any unusual changes in your thoughts or behavior.

Estazolam can be habit-forming. Do not take a larger dose, take it more often, or take it for a longer time than prescribed by your doctor.

If your doctor has told you to take estazolam regularly, talk to your doctor before you stop taking this medication. Your doctor will probably decrease your dose gradually. If you suddenly stop taking estazolam, you may experience withdrawal symptoms such as difficulty falling asleep or staying asleep, uncontrollable shaking of a part of the body, stomach and muscle cramps, vomiting, sweating, sad mood, seeing things or hearing sounds that do not exist, and seizures.

Your doctor or pharmacist will give you the manufacturer's patient information sheet (Medication Guide) when you begin treatment with estazolam and each time you refill your prescription. Read the information carefully and ask your doctor or pharmacist if you have any questions. You can also visit the Food and Drug Administration (FDA) website Web Siteor the manufacturer's website to obtain the Medication Guide.

Are there OTHER USES for this medicine?
This medication may be prescribed for other uses. Ask your doctor or pharmacist for more information.
