Clinical studies have not been conducted on doses above 20 mg for Lexapro as far as I can read. Literature says:
The recommended dose of Lexapro is 10 mg once daily. A fixed-dose trial of Lexapro demonstrated the effectiveness of both 10 mg and 20 mg of Lexapro, but failed to demonstrate a greater benefit of 20 mg over 10 mg.
Although a chemically related medication, Celexa, is prescribed at doses of 40 mgs. so maybe that is what your doctor is banking on.
Maybe you need to give it a try and if it doesn't help over the next month you may need to try a different antidepressant. There are many to choose from and what works for one doesn't always work for another. Unfortunatley it is a trail and error sort of deal.
