Temazepam Patient Tips

Written by C. Fookes, BPharm on May 30, 2016

How it works

Temazepam is a benzodiazepine (type of medicine used to calm and sedate) used for the short-term relief of insomnia. Symptoms of insomnia include trouble falling asleep or waking often in the night.


  • Useful for the short-term relief (less than seven to ten days) of insomnia. Has more sedative properties, but less anti-seizure and anxiolytic effects than some other benzodiazepines such as diazepam and oxazepam.


If you are between the ages of 18 and 60, take no other medication or have no other medical conditions, side effects you are more likely to experience include:

  • Dizziness, headache, oversedation, short-term memory loss, coordination problems, and confusion are common side effects.
  • If you take temazepam you should not drive, operate machinery, or perform tasks that require mental alertness. Avoid alcohol.
  • May rarely cause a drop in blood pressure, especially from sitting to standing. Caution in elderly patients.
  • Adverse effects appear dose related; never exceed the prescribed dose and use only the lowest effective dose.
  • Withdrawal symptoms (tremor, abdominal and muscle cramps, vomiting, sweating, rarely seizures) may occur if temazepam has been taken long-term or at higher-than-recommended dosages and is stopped abruptly; discontinue slowly on a doctor's advice. Even after regular dosing, mild withdrawal symptoms (such as low mood, insomnia) may occur if temazepam is discontinued abruptly. May not be suitable for people with a history of substance abuse or addictive disorders.
  • Should not be used during pregnancy; associated with an increased risk of birth defects.
  • Paradoxical reactions (the opposite of what is expected), such as worsening of insomnia, aggressiveness, hallucinations, extroversion, and rage have been reported, mainly in people with other mental health concerns. Seek medical advice if these occur.
  • Reports of "sleep-driving” (driving while not fully awake), and other behaviors (eg, eating, making phone calls, having sex) after temazepam ingestion are documented. Risk may be exacerbated by large doses or alcohol. Seek medical advice if this occurs.
  • May interact with several other medicines, including other drugs that have sedation as a side effect. See prescribing information for a full list of interactions.
  • May not be suitable for some people including those with respiratory disease, kidney or liver disease, psychiatric illness, or those with a history of substance abuse or addictive disorders.

Notes: In general, seniors or children, people with certain medical conditions (such as liver or kidney problems, heart disease, diabetes, seizures) or people who take other medications are more at risk of developing a wider range of side effects.

Bottom Line

Temazepam is a benzodiaepine used to help people sleep. It is habit forming so should be used for no more than seven to ten days at a time.


  • Take just before bedtime.
  • Only use temazepam for short periods of time to help with sleep (no more than seven to ten days) as it can be habit-forming. Sleep disturbance can be a sign of some other underlying disorder. Call your doctor if your insomnia worsens or does not improve within seven to ten days.

Response and Effectiveness

  • Temazepam takes about 30 to 60 minutes to start working, with peak effects seen at three-quarters to one hour. Effects last approximately seven to eight hours. Because of this, do not take temazepam if you do not intend to stay asleep or in bed for at least eight hours. Otherwise you may find yourself still under the effects of the drug, which may affect your ability to concentrate or drive.
