When sleep medicines are used every night for more than a few weeks, they may lose their effectiveness to help you sleep. This is known as TOLERANCE. Sleep medicines should usually be used only for short periods of time, such as a few days and generally no longer than 1 or 2 weeks. If your sleep problems continue, contact your doctor.

When used for longer than a few weeks or at high doses, some people develop a need to continue taking Halcion . This is known as DEPENDENCE or addiction.

WITHDRAWAL symptoms may occur when Halcion is stopped suddenly after being used daily for a long time. But these symptoms can occur even if Halcion has been used for only a week or two. In mild cases, WITHDRAWAL symptoms may include unpleasant feelings. Although uncommon, in more severe cases, abdominal and muscle cramps, vomiting, sweating, shakiness, and, rarely, seizures may occur. Another problem that may occur is "rebound insomnia," that is, more trouble sleeping the first few nights after the medicine is stopped than before starting the medicine. This usually goes away after 1 or 2 nights. If you have been taking Halcion for more than 1 or 2 weeks, do not stop taking it on your own. Your doctor may give you special directions on how to gradually decrease your dose before stopping the medicine. Always follow your doctor's directions.
