How does diazepam work?
Diazepam works by increasing the effect of several naturally occurring chemicals in the brain that make you feel calm, relaxed and sleepy. It can:

cause a sedative effect
controls spasms or seizures

What is diazepam used for?

Diazepam is usually used only for short periods of time, around 2 to 4 weeks. This might be while other anti-anxiety medications take effect. Your doctor may advise a different plan if you need it. If you use diazepam over a longer period, there is a risk that you will become dependent.
Diazepam is also used to:
relax muscles
treat muscle spasms caused by injury or conditions such as cerebral palsy and paraplegia
treat symptoms of alcohol withdrawal, such as trembling, confusion and anxiety
Your doctor may have prescribed diazepam for another reason. If you are not sure why your doctor has prescribed diazepam, ask your doctor.
