Escada 20 mg (Escitalopram) is usually prescribed for anxiety or depression, and taking it for 16 months is quite common, as these conditions often need longer treatment to keep symptoms under control and prevent them from returning; however, the exact duration depends on how stable you have been and your past history. It is not a good idea to reduce the dose on your own, even if you feel better, because a sudden decrease can lead to symptoms like anxiety, irritability, or disturbed sleep coming back. In many cases, doctors may consider reducing the dose to 10 mg only after you have been stable for a sufficient period, and this is usually done gradually and under supervision. So, before making any change, it is best to consult your doctor, who can review your progress and guide you on whether dose reduction is appropriate and how to do it safely.
