Hi Azalea3,
Celexa and Cipralex are the 'same' drug in exactly the same way as an Orange and a Lemon are the same thing.
In Chemistry some molecules are Chiral, which means that the molecule is asymmetrical, such that it can have a different chemical which is a mirror image of itself.
Celexa is a tradename of the drug Citalopram, whereas Cipralex is a tradename of is chiral opposite, the drug Escitalopram.
Escitalopram was developed more recently, and is believed to be equally effective as Citalopram, but with reduced side-effects.
Incidentally, the chemical in both oranges and lemons which give each their unique smell is in both cases limonene, but in oranges it is the 'left-handed' version and in lemons the 'right-handed' one.
http://americanhistory.si.edu/molecule/04exp.htm I suggest that you raise your concerns with your Doctor.
I suspect that if you are still not feeling an improvement in your depression that they may well consider moving you to Citalopram (which is a less expensive drug).
Please note, you should only change your medication regime under the guidance of your Doctor.
Best Regards,
John
