Flurazepam (oral)

Flurazepam is prescribed for insomnia to help patients fall asleep.


Flurazepam treats mild cases to moderate cases of insomnia (difficulty sleeping, waking early, or waking frequently throughout the night) for patients over the age of 15. This medication is intended to be used only for the short-term. Flurazepam helps patients to sleep throughout the night and to fall asleep faster.

Flurazepam is a medication known as a benzodiazepine. Benzodiazepine are CNS (central nervous system) depressants, which are medications that effectively reduce the speed of the nervous system.

A metabolite with an extended half-life is produced by flurazepam, which means that this medication can be present in the bloodstream over the period of several days. There are also half-life intermediate benzodiazepines available, and these are specifically useful in patients who have a hard time sustaining sleep (temazepam, lormetazepam, or loprazolam).

Flurazepam can only be obtained with a valid prescription from your physician.

This medication is currently only available in capsules. It is currently manufactured under the US brand names of Dalmane and Dalmadorm.
