Key takeaways
Buspirone and lorazepam (brand names Ativan, Loreev XR) are both used to treat anxiety, but they have some key differences. Buspirone is an antianxiety medication that is not a controlled substance and is typically taken twice daily. It takes a few weeks to start working and is not for quick relief of anxiety. Common side effects include dizziness, nausea, and headache. Lorazepam, on the other hand, is a benzodiazepine and a Schedule IV controlled substance, meaning it has a higher risk of dependence and misuse. It works faster than buspirone, often within 30 minutes, and is used for short-term relief of anxiety. Lorazepam can cause sleepiness and dizziness and has a risk of withdrawal symptoms if stopped suddenly. While buspirone is generally considered safer for long-term use, lorazepam is more effective for immediate anxiety relief.
