Halcion: triazolam

What Is It?

Halcion is in a class of drugs called benzodiazepine and is the brand name for triazolam.

It is prescribed to treat insomnia, including falling asleep, waking during the night, and early morning wakefulness.

Prescriptions generally say to take Halcion (triazolam) 30 to 60 minutes before bedtime.

If stomach upset occurs it can be taken with a full glass of water or food. Take it just before you get into bed, since it causes drowsiness, and falling could occur if the dose is taken too long before getting into bed.


Halcion (triazolam) is abused as tolerance develops. When the drug is taken over time, higher doses must be taken to get the same effect.

Withdrawal can cause the original problem to reappear temporarily when taken for a long time.

When used for more than two weeks, physical dependence can occur.  For this reason it is important NOT to stop taking Halcion (triazolam) suddenly if you have been taking a large amounts or used it for several weeks.

Common side-effects of taking Halcion include: Clumsiness or unsteadiness; daytime drowsiness; dizziness; fatigue; feeling of hangover; headache; light-headedness; nausea; nervousness; sluggishness; unusual weakness.
