Diazepam has been used in clinical practice for many years and is one of the most widely recognised benzodiazepine medicines. It is available only with a valid prescription in the UK and should always be supplied through a registered pharmacy.

Depending on your medical condition, your healthcare professional may prescribe diazepam for:

• Short-term treatment of severe anxiety
• Muscle spasms and muscle stiffness
• Certain seizure disorders
• Alcohol withdrawal symptoms
• Sedation before medical or dental procedures

Your doctor will determine whether diazepam is appropriate based on your symptoms, medical history, current medicines, and overall health.

How Does Diazepam Work?

Diazepam acts on receptors in the brain that respond to GABA, the body’s primary inhibitory neurotransmitter. By enhancing GABA’s calming effects, diazepam slows excessive nerve activity.

This may help to:

• Reduce feelings of anxiety and panic
• Relax skeletal muscles
• Control certain types of seizures
• Promote relaxation before medical procedures
• Reduce agitation associated with alcohol withdrawal

Because diazepam affects the central nervous system, it may also cause drowsiness, slower reaction times, impaired concentration, and reduced coordination.

What Is Diazepam Used For?

Healthcare professionals prescribe diazepam for several clinically approved indications.

Severe Anxiety

Diazepam may be prescribed for the short-term management of severe anxiety when symptoms significantly interfere with daily life.

Muscle Spasms

Certain neurological conditions or injuries can cause painful muscle spasms. Diazzepam may help relax affected muscles and reduce discomfort.

Seizures

In some emergency situations, diazepam is used to help control prolonged seizures under medical supervision.

Alcohol Withdrawal

Patients experiencing alcohol withdrawal may receive diazepam as part of a carefully monitored treatment programme.

Before Medical Procedures

Some patients receive diazepam before surgery or other medical procedures to reduce anxiety and help them relax.

Can Diazepam Cause Dependence?

Yes.

Diazepam belongs to the benzodiazepine family, which can cause physical dependence and tolerance, particularly with prolonged use or higher doses.

To reduce this risk:

• Treatment is usually kept as short as possible.
• Your doctor may review your treatment regularly.
• If treatment needs to stop, your dose is usually reduced gradually.

Never stop taking diazepam without medical advice.

Diazepam can interact with many medicines and substances.

Inform your healthcare professional if you take:

• Opioid pain medicines
• Sleeping tablets
• Other benzodiazepines
• Antidepressants
• Antipsychotics
• Antihistamines that cause drowsiness
• Epilepsy medicines
• Alcohol

Combining diazepam with alcohol or certain medicines may increase the risk of excessive sedation, breathing difficulties, or other serious adverse effects.

Driving and Operating Machinery

Diazepam can impair alertness, reaction time, judgement, and coordination.

You should not drive or operate machinery if you feel sleepy, dizzy, or unable to concentrate. Always follow the advice given by your healthcare professional and comply with UK driving regulations.

Pregnancy and Breastfeeding

If you are pregnant, planning a pregnancy, or breastfeeding, speak with your healthcare professional before taking diazepam.

Your prescriber will carefully consider the potential benefits and risks before recommending treatment.

If you miss a dose, follow your prescriber’s instructions.

Do not take a double dose to make up for a forgotten tablet.

Storage Information
