Upsides
  • Available in a cheaper, generic form.
  • Is convenient and can take once a day.
  • Effective at relieving short-term anxiety and sleeplessness.
  • Can be used together with antidepressants to manage anxiety disorders. Especially helpful for anxiety symptoms while you wait for an antidepressant to kick in (it can take several weeks).
  • Can be used alone or with other medicines to treat seizures.
  • Less severe withdrawal symptoms compared to other benzodiazepines.
Downsides
  • More likely to decrease your sexual appetite and delay or prevent ejaculation than other antidepressants.
  • Like most antidepressants, Paxil (paroxetine) has a high risk of suicidal thoughts and behavior when used in children and adolescents.
  • May not be appropriate for you if you are elderly or suffer from dementia.
  • Can cause memory problems, drowsiness, dizziness, and confusion.
  • Can be habit-forming, so it's not typically used for long-term treatment, or for people who've had problems with drug or alcohol abuse.
  • Most people find that it gets less effective over time.
