Xanax and lorazepam are benzodiazepines prescribed to treat anxiety and related conditions, but they differ in onset and duration of action. Xanax works quickly and is commonly used for acute anxiety and panic attacks. Lorazepam has a slightly longer-lasting effect and is often used for generalized anxiety, insomnia related to anxiety, and medical procedures. Both medications calm the nervous system and may cause drowsiness, dizziness, and impaired coordination. Because they carry risks of dependence and withdrawal, healthcare providers carefully consider dosage, duration, and patient history when selecting the most appropriate option for treatment.
