Cipralex made me go a bit too "high" several years ago so I stopped taking it. At the moment I'm on celexa and it works well for me, but everyone is different. I hope this medication works well for your son.

As a side note, does your son exercise? I definitely am helped by my anti-depressant but I am equally helped by regular exercise. It can make a huge difference in several mental illnesses, including depression and anxiety. Even walking is great for you.
