Antidepressants and birth control pills?

Ellaine
I'm currently on Citalopram(Lexapro) and I'm planning to start using BC pills for the first time. My anxiety is at its highest when I'm in college. I was wondering if any of you guys are taking the same medication as me? Or any type of antidepressant while on birth control? Is BC pills still as effective and vise versa? Sorry for so many questions lol.
