PLEASE help me, ?'s about side effect of Effexor in adolescents

My step son is 17 and having serious depression for a couple years and tried various meds. He went into a pych hospital for a couple weeks when he just couldn't function, go to school etc. They chose EFFEXOR to help him, and it actually seemed to be VERY helpful. HOWEVER, he has been having these (WE THINK they are dreams that seem real.. memories that are false. For instance, he helped improve the stealth bomber and a troop transport vehicle. He thinks when he was in the hospital that Jon Stewart from the DAILY SHOW came to visit him, and when he came home from the hospital, he feels Jon sang a song to him that he requested and then said on air, Cheer up Kevin! There are more delusions that we know could not have happened too numerous to list. He sat us down last night and told us all about them wanting to know once and for all if they were true, and of course we had to tell him they were not. Couple weeks ago when he first told us a LITTLE bit about the delusions, we searched about side effects of effexor and read they can cause vivid dreams. After a little more research we found some posts on different sites where people claimed not only did they have vivid dreams but that they were positive they were true. This is NOT medtioned on any of the side effects on the actual medication. We took him to our GP who is very knowledgable and he switched him to LEXAPRO, about 3 weeks ago. He's very discouraged as he feels the Lexapro should be working by now and he shouldn't still be thinking of these delusions as real. I tried to explain to him that memories false or not are always going to be memories, and as long as he realizes that I hope that should help him accept it. I have a call into his councelor now, but he's on vacation and frankly I have NOOOOOOOOO idea what to do. I'm very proud of him that he had the courage to come tell us about these false memories, but he's SOOOO depressed and he feels totally helpless and that he will never be able to enjoy life but just exist in life. Has anyone else had this experience ?? Any suggesions?

Hi Mrspatwolf.. I replied to your post about this in the Caregiver's forum.

My first comment would be to get him back to a Pdoc ASAP. A GP is great for "general" health issues. But for mental health issues, especially those that involve delusions, a competent pyschiatrist is needed.

That being said.....in the beginning Effexor gave me such vivid dreams that I could not sleep. I now take all me Effexor XR in the morning.

Good luck to you and your son.
