Temazepam (patient information)
IMPORTANT WARNING:
[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.
Why is this medication prescribed
See the MedWatch notification at the beginning of the monograph.
Temazepam is used on a short-term basis to help you fall asleep and stay asleep through the night.
This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.
How should this medicine be used
See the MedWatch notification at the beginning of the monograph.
Temazepam comes as a capsule 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 temazepam exactly as directed.
Temazepam can be habit-forming. Do not take a larger dose, take it more often, or for a longer period than your doctor tells you to. Tolerance may develop with long-term or excessive use, making the drug less effective. Do not take temazepam for more than 5 weeks or stop taking this medication without talking to your doctor. Stopping the drug suddenly can cause withdrawal symptoms (anxiousness, sleeplessness, and irritability). 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.
