Frequently Asked Questions
Generic diazepam costs $4 to $15 per month without insurance. It is one of the oldest and most affordable benzodiazepines available.
Diazepam (Valium) treats anxiety disorders, muscle spasms, seizures, and alcohol withdrawal. Its long duration of action makes it useful for conditions requiring sustained relief.
Diazepam has a very long half-life of 20-100 hours, and its active metabolite (desmethyldiazepam) can last even longer. It can be detected in urine for 1-6 weeks after use.
