General & Family Physician,  's  Response
Hello and Welcome to ‘Ask A Doctor’ service.
I have reviewed your query and here is my advice.

You indicated that you had anxiety prior to the use of the Lexapro. It is also important to note that anxiety itself can cause the blood pressure to be elevated. This means that your present anxiety and blood pressure readings may not have anything to do with your medication. Lexapro and similar medications can take 1 to 3 weeks before they start to work.
You should discuss your options with your doctor. The half life of a medication is the time it takes for the amount of drug in the body to decrease by half. It takes approximately 3 to 5 half lives for a medication to be mostly eliminated. The half life of Lexapro is 27 to 32 hours.

Hope I have answered your query.
Let me know if I can assist you further.
