Temazepam
What is temazepam?
Temazepam is a prescription medicine from the benzodiazepine class. It is mainly used as a short-term treatment for severe insomnia. It may also be used to relieve anxiety before surgery or certain medical procedures[1].
What is temazepam used for?
Temazepam is prescribed for the following conditions[1]:
Short-term insomnia (typically 2 to 4 weeks)
Reducing anxiety and helping patients sleep before medical or dental surgery
How does temazepam work?
Temazepam works by enhancing the effect of gamma-aminobutyric acid (GABA), a natural calming chemical in the brain. By slowing brain activity, it helps you relax, fall asleep faster, and stay asleep longer[1].
Who can take temazepam?
Temazepam is suitable for most adults aged 18 and over. However, it may not be safe for everyone. You should not take temazepam if you[1]:
Are allergic to benzodiazepines
Have severe liver problems

Have a history of mental health conditions such as depression, anxiety, psychosis or substance misuse disorders

Please tell your doctor or pharmacist about any conditions you may have or medication you take before you start treatment, and always follow the instructions in the Patient Information Leaflet[2].
What is the typical dosage of temazepam?
Temazepam comes as 10mg and 20mg tablets. Temazepam liquid contains 10mg of temazepam in each 5ml. The dosage depends on your age, general health, and the condition being treated[1]:
For sleep problems in adults, the dosage is 10mg to 20mg, taken once a day usually at bedtime
In some cases, your doctor may prescribe a higher dose of 30mg to 40mg. If you’re over 65 and at risk of falling over, your dose may be lower

Frequently asked questions about temazepam
Is temazepam addictive?
A short course of low dose temazepam is unlikely to cause addiction, however the chances of addiction forming is increased if there is a history of substance misuse or if you are taking temazepam for a long time or at high doses[1].
Can I drink alcohol while taking temazepam?
No. Alcohol increases the sedative effects and the risk of serious side effects. You should also avoid caffeine as it’s a stimulant that can reduce the effects of the drug[1].
Can I drive the next day?
Only if you feel fully alert. Drowsiness may persist and affect your ability to drive safely. If you have any doubt, do not drive[1].
Is temazepam safe during pregnancy?
No. It may harm the baby and cause withdrawal symptoms in newborns[1].
Can I take temazepam every night?
Only for a short time. Continuous use for longer than 4 weeks is not recommended[1].
Does temazepam help with anxiety?
It may be used short-term to calm anxiety before surgery but is not a first-line treatment for ongoing anxiety[1].
Is temazepam the same as diazepam?
No. They are both benzodiazepines but differ in how quickly they act and how long their effects last[1].
Can I take temazepam abroad?
Check with the embassy of the nation if you can take your medicine abroad as some countries have different rules for temazepam[1].
