Your best bet is to ask your pharmacist.
Celexa is essentially the same as Lexapro and is available as a generic.
i was also on Lexapro, but it became expensive so I am on Celexa which is a sister medication to Lexapro. Celexa has a generic called Citalopram. However, you might need to take a higher dose of Celexa if it is a good idea for you to switch. Talk to your doc to make sure.....Just my thoughts.
Be the Pharmacist. Feel it. Do it.You are a Pharmacist.
