Buspar vs. Valium
See how Buspar and Valium compare on approved uses, dosing, side effects, and cost.
Key Takeaways
Buspar (buspirone) is a non-controlled anxiolytic that takes one to two weeks to build effect, while Valium (diazepam) is a benzodiazepine that works within about an hour but carries boxed warnings for dependence and misuse.
Buspar is dosed twice daily and adjusted over days to weeks, while Valium's dose and frequency depend on the specific condition being treated, from mild anxiety to acute muscle spasm or seizures.
Because Valium carries FDA boxed warnings for abuse, dependence, and dangerous interactions with opioids, it is generally meant for short-term use, while Buspar is considered suitable for longer-term daily use.
