Lorazepam and Xanax (alprazolam) are both benzodiazepines used to treat anxiety disorders, so they share many similarities. However, there are some key differences:

  • Onset and Duration: Xanax acts faster, kicking in within 30 minutes, while Lorazepam (Ativan) takes up to two hours. Conversely, Lorazepam's effects last longer (around 8 hours) compared to Xanax (4-6 hours).
  • Strength: Xanax is generally considered stronger than Lorazepam, although this can depend on individual factors and dosage.
  • Side Effects: Both can cause drowsiness and dizziness, but Lorazepam might have fewer interactions with other medications.

Here's a table summarizing the key differences:

In essence, Lorazepam and Xanax are not exactly the same, although they serve a similar purpose. A doctor can determine which medication is best suited for your specific needs and anxiety condition.
