  • Prosom (estazolam) is available in generic.
Downsides

  • 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.
  • Compared to other similar medicines, Ativan (lorazepam) is more likely to cause withdrawal if you take it for a long time and then suddenly stop.
  • Most people find that Ativan (lorazepam) gets less effective over time.
  • Prosom (estazolam) isn't recommended if you're age 65 or older because the side effects can be more intense.
