I'm having a very addictive behavior i think my dopamine is high and i'm on cipralex i know it raises serotonin but can it lower dopamine as well ?

No: It really would not lower your dopamine levels much

Possibly: From how I understand it, Cipralex is mainly a selective serotonin reuptake inhibitor,meaning that it should dramatically increase the amount of serotonin available and thus indirectly block the dopamine receptors because there is so much of the serotonin now available and that is what indirectly blocks the dopamine from its receptor and thus decreases the dopamine levels/level of receptors firing
