Upsides
  • Effectively treats a variety of mental health conditions such as depression, OCD, and panic disorder.
  • It's more energizing than other antidepressants, so it's good for people who have low energy.
  • Might be a good option for treating children with depression and/or OCD.
  • Doesn't have effects on the heart unlike other antidepressants so it may be a better treatment choice for older people.
  • Can cause a significant amount of weight loss which is an added benefit for those who are overweight or obese.
  • Doesn't cause as much physical dependence or withdrawal symptoms as other medications used for anxiety.
  • Available as a generic, which is cheaper.
  • Tablets can be split for easy dose changes.
  • Doesn't cause as much drowsiness as other medications for anxiety.
Downsides

  • Can lower your sex drive.
  • Can increase the risk of suicidal thoughts and/or behavior in those age 24 or younger.
  • You may need to try out several different antidepressants before you find the one that works for you.
  • Not for quick relief of anxiety symptoms since Buspar (buspirone) can take as long as 4 weeks to fully work.
  • Not as effective for short-term anxiety conditions or panic disorders.
  • Some people find that Buspar (buspirone) loses effectiveness over long periods of time.
  • Must take Buspar (buspirone) twice daily for full effect.
