Medicines like Escitalopram and Clonazepam are used for different purposes and durations: escitalopram is usually taken for several months to treat depression and anxiety and is generally safe for long-term use under a doctor's guidance, while clonazepam is meant for short-term relief of anxiety or insomnia, typically for a few weeks to a few months, because it can cause dependence if used for longer periods. Doctors often start clonazepam briefly and then gradually reduce (taper) it once symptoms are controlled, while continuing escitalopram for maintenance. It is important not to stop either medicine suddenly, as this can cause withdrawal symptoms or return of symptoms, and all dose changes should be done under medical supervision.
