  • Short-term relief of anxiety symptoms

  • Off-label: adjunct treatment for depression

  • Off-label: SSRI-related sexual dysfunction

Buspar vs. Ativan Pros and Cons

Buspar

Buspar is not a controlled substance and carries no meaningful risk of abuse or physical dependence, making it a reasonable option for long-term anxiety management. It does not exhibit cross-tolerance with benzodiazepines, so it cannot ease benzodiazepine withdrawal symptoms. It is not approved for panic disorder, and combining it with MAOIs or other serotonergic drugs raises the risk of dangerous interactions.

Pros

  • Not a controlled substance, minimal abuse or dependence risk

  • No boxed warning on the current label

  • Lower risk of sedation-related falls, especially in older adults

  • Fewer prescribing restrictions since it isn't a scheduled drug

Cons

  • Not approved for panic disorder

  • Risk of hypertensive crisis when combined with MAOIs

  • Doesn't relieve benzodiazepine withdrawal symptoms

  • No injectable option for urgent sedation

Ativan

Ativan works quickly for acute anxiety and is available as an injectable for urgent sedation or preanesthetic use, but it carries boxed warnings for abuse, dependence, and severe withdrawal. Sedation and fall risk increase with age, and combining it with opioids can cause dangerous respiratory depression. It is not recommended for long-term use beyond four months or in patients with significant liver or kidney impairment.

Pros

  • Fast-acting relief for acute anxiety symptoms

  • Available as an injectable for preanesthetic sedation or urgent use

  • Also used off-label for status epilepticus

  • Effective for anxiety accompanied by depressive symptoms

Cons

  • Boxed warnings for abuse, dependence, and withdrawal risk

  • Not recommended for use beyond four months

  • Sedation and fall risk increase with age

  • Dangerous interaction risk when combined with opioids
