Why diazepam may be prescribed

Severe short-term anxietyFor selected cases after clinical assessment.

Mechanism of action

How diazepam works

Diazepam enhances the effect of gamma-aminobutyric acid, also known as GABA, an inhibitory chemical messenger in the brain. This reduces excessive nervous-system activity and can produce calming, sedative, anticonvulsant and muscle-relaxant effects.

Oral effects may begin within roughly 30 to 60 minutes, although timing varies. Diazepam and its active metabolites can remain in the body for a prolonged period, increasing the risk of accumulation, daytime drowsiness and interactions.

Oral onsetOften 30 to 60 minutes
Peak concentrationOften within 2 to 4 hours
DurationCan be prolonged
Protein bindingHigh

Individual response varies. Do not use these timings to self-dose.

Safety information

Common precautions before taking diazepam

Diazepam can cause dependence, sedation and dangerous breathing problems

Combining diazepam with alcohol, opioids or other sedatives can be life-threatening.

What to do

  • Take it exactly as prescribed.
  • Tell the prescriber about all medicines and substances you use.
  • Use the lowest effective dose for the shortest appropriate duration.
  • Report severe drowsiness, confusion, unusual agitation or breathing difficulty.
  • Store it securely and out of reach of children.

What not to do

  • Do not drink alcohol while taking diazepam.
  • Do not drive or use machinery until you know how it affects you.
  • Do not share the medicine with another person.
  • Do not increase the dose or frequency without medical advice.
  • Do not stop suddenly after regular or prolonged use.

Dose and stopping treatment

Use only the dose written on your prescription

Diazepam dosing varies substantially according to the indication, age, liver function, breathing conditions, frailty, other medicines and previous benzodiazepine exposure. A general dosing table is not a substitute for individual prescribing.

Regular use can lead to physical dependence. After prolonged use, stopping suddenly can cause severe withdrawal symptoms, including seizures. Any reduction should be planned and monitored by a qualified clinician.

Never copy another person’s dose or use a tapering schedule taken from a website.
