IMPORTANT WARNING: Return to top

[Posted 03/14/2007] FDA notified healthcare professionals of its request that all manufacturers of sedative-hypnotic drug products, a class of drugs used to induce and/or maintain sleep, strengthen their product labeling to include stronger language concerning potential risks. These risks include severe allergic reactions and complex sleep-related behaviors, which may include sleep-driving. Sleep driving is defined as driving while not fully awake after ingestion of a sedative-hypnotic product, with no memory of the event. FDA also requested that each product manufacturer send letters to health care providers to notify them about the new warnings, and that manufacturers develop Patient Medication Guides for the products to inform consumers about risks and advise them of potential precautions that can be taken. For more information visit the FDA website at: http://www.fda.gov/medwatch/safety/2007/safety07.htm#Sedative and http://www.fda.gov/bbs/topics/NEWS/2007/NEW01587.html.

How should this medicine be used? Return to top

See the MedWatch notification at the beginning of the monograph.

Estazolam comes as a tablet to take by mouth and may be taken with or without food. It usually is taken before bedtime when needed. 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.

Estazolam can be habit-forming. Do not take a larger dose, take it more often, or for a longer time than your doctor tells you to. Tolerance may develop with long-term or excessive use, making the drug less effective. Do not take estazolam for more than 12 weeks or stop taking this medication without talking to your doctor. Your doctor probably will decrease your dose gradually. You may experience sleeping difficulties the first one or two nights after stopping this medication. If your sleep problems continue, talk to your doctor who will determine whether this drug is right for you.
