From the Guidelines
Diazepam is a prescription benzodiazepine medication used to treat anxiety disorders, alcohol withdrawal symptoms, muscle spasms, and seizures, with a typical adult dose ranging from 2-10 mg taken 2-4 times daily, as directed by a physician, and should be used with caution due to its potential for dependence and withdrawal symptoms.
Key Points
- Diazepam works by enhancing the effects of GABA, a neurotransmitter that reduces brain activity, resulting in a calming effect, as noted in studies such as 1.
- It's fast-acting but can be habit-forming, so it's generally prescribed for short-term use, with treatment usually lasting 2-4 weeks for anxiety, as seen in 1.
- Common side effects include drowsiness, dizziness, and impaired coordination, and patients should avoid alcohol and use caution when driving or operating machinery while taking diazepam, as warned in 1.
- Abrupt discontinuation can cause withdrawal symptoms, so dosage should be tapered gradually under medical supervision, as advised in 1.
- While effective for short-term relief, diazepam is not recommended for long-term anxiety management due to tolerance and dependence risks, and non-pharmacological approaches like cognitive behavioral therapy should be considered for ongoing anxiety treatment, as suggested in 1.
Important Considerations
- The use of diazepam should be carefully balanced against the risk of harms, including dependence and withdrawal symptoms, as highlighted in 1.
- Patients taking diazepam should be closely monitored for signs of dependence and withdrawal, and dosage should be adjusted accordingly, as recommended in 1.
- Alternative treatments, such as non-pharmacological approaches, should be considered for patients with anxiety disorders, as suggested in 1.

From the Research
Definition and Uses of Diazepam
- Diazepam is a benzodiazepine with a wide range of therapeutic uses, including hypnotic, anxiolytic, anticonvulsant, myorelaxant, and amnesic effects 3.
- It is commonly used for the treatment of anxiety disorders, insomnia, seizures, and alcohol withdrawal syndrome 3, 4, 5, 6.
- Diazepam is often preferred for its rapid onset of action and high efficacy in controlling symptoms, particularly in severe cases of anxiety and alcohol withdrawal 5, 6.
Pharmacological Properties
- Diazepam has a fast onset of action when administered intravenously and a long elimination half-life, which allows for a gradual decrease in levels and a smoother withdrawal 6.
- Its active metabolite, desmethyldiazepam, also contributes to its therapeutic effects and prolonged duration of action 6.
- The pharmacokinetics of diazepam make it a suitable choice for the treatment of moderate to severe alcohol withdrawal, with a lower risk of breakthrough symptoms and rebound phenomena 6.
Clinical Applications
- Diazepam is used in the treatment of acute stress reactions, episodic anxiety, and fluctuations in generalized anxiety, as well as for the initial treatment of severe panic and agoraphobia 3.
- It is also used in the management of epilepsy, anesthesia, and some motor disorders, and occasionally in acute psychoses 3.
- In the context of alcohol withdrawal, diazepam is often used to control symptoms such as autonomic hyperactivity, agitation, and hallucinations, and to prevent complications like seizures and delirium 5, 6.
