Lexapro (escitalopram) is a medication used to treat anxiety and depression; it belongs to a group of drugs called selective serotonin reuptake inhibitors (SSRIs). It is an antidepressant that works by inhibiting the reuptake of serotonin by the nerves, and it restores the balance of serotonin in the brain. Lexapro can improve energy levels and well-being and decrease nervousness.


The dosage for Lexapro depends on the patient’s condition, age, other medications they are taking and response to treatment. So, you need to speak to a healthcare provider to determine your dosage. 

However, the dosage for a generalised anxiety disorder is 10mg daily to be taken orally. It can be taken in the morning or evening, but you need to take it at the same time every day. Your doctor can increase your dose to 20mg if need be, but the starting dose is usually 10mg. 

In addition, treatment should be reassessed periodically by your doctor to determine the need for ongoing treatment and the appropriate dosage according to your improvement. Mind you, the efficacy of this drug beyond eight weeks has not been studied.
