I have had good response from the drug lexapro for depression. However, I became recently unemployed and am now paying out of pocket for this drug. I have to take it along with wellbutrin XL for the time being. Since the price of both lexapro and wellbutrin XL are high, my druggist suggested I try celexa since it is available in the generic and is much cheaper than the brand lexapro. What can I expect?
