Lorazepam and Xanax are both benzodiazepines used to treat anxiety, but they differ in how fast they work and how long their effects last. Xanax acts quickly and is short-lasting, while lorazepam works slightly slower but lasts longer in the body. The right choice depends on the condition being treated, patient history, and medical advice.

Xanax is also a benzodiazepine. Its generic name is alprazolam. It is commonly used for:
