Can I use male enhancement while taking antidepressant?

I have been taking Lexapro(Antidepressant) for 2 months, And yesterday I used Sextagin TM Hardcore Male Enhancement that I bought from Amazon (http://www.amazon.com/gp/product/B0028P40YW/ref=oh_o00_s00_i00_details). In it's introduction, it says to ask a doctor bofore to those who are taking antidepressant.
