I hadn't heard of Citalopram yet, so I looked it up... I guess there's different strengths, but it seems to work like most of the other ones... Anyway, I think I read the research right, but anyone can feel free to correct me... I'm not a doctor or anything like that, so it's up to you if you wanna go with anything I say =0)
There was some discussion a couple years ago about taking out one of the ingredients so that the others would work better, but I think maybe then it would be too strong, because when you are on antidepressants supposedly the body produces more serotonin, making you feel all warm and fuzzy inside... or something like that... I think that if you get too much you start to show parkinson's... So... Uh... Yeah, I forgot where I was going with that... {edit* I remember now... You should stick with the dose your doc tells you to take... If you take any more than you are supposed to it will only cause more problems }Lol... The website did say it interacted with oocytes and something about invitro... A lot of it was over my head, but as long as you aren't pregnant or don't plan on becoming pregnant any time soon you'll be fine.
Still, you probably won't start to feel anything for a month more (pubmed says 4-6 weeks)... So depending on when you started, just stick with them but if you start to feel any worse from it you should talk to your doc again... The stuff is working with the cells in your brain, so some people might have a reaction to the med... In that case they can find you another med that works with different chemical receptors and all that...
Don't give up though, that stuff really can help, I took some antidepressants a couple years ago so I could stop feeling so down and work on sorting things out... They helped a lot and since I've been a LOT better of from being able to get out of my own head for a while, ya know?
Wow, long reply... Sorry, hope that helps some...
