Citalopram (Celexa) side effects and experiences?

Anyone have some insight here?
My doctor put me on Charles Schwab (Citalopram) to help manage some anxiety and depression issues.
From what I can see, the price tag is sitting around $47.
Does this require a specific prescription, or is there a generic version out there that works with insurance co-pays?
Does anyone know the other names used for this type of medication?
This is getting ridiculous...

You still need a prescription for Cipralex, but you’re definitely paying out of pocket for it.

Pfizer makes a version called Elicea that doesn't cost you a dime at the pharmacy.
It's also available by prescription.
