In response to your questions, I hope this is helpful. :)
"Since you work in a Mental Health Center, I am hoping you can answer some of my questions. Do antidepressants work differently, or are they all the same kind of medications just with different names? Ex: I know Paxil is used for several things like social problems, anxiety and ect...so what is Celexa used for?"
Each antidepressant is slightly different, even if it is just a reformulation of an old medication. They may each work slightly differently as an SSRI, and not all SSRI's will work for everyone because we are all biochemically unique. Each med. may have a slightly different affect on the receptor sights in the brain, you just need to find the one that works the best for yours.
As far as uses, many antidepressants are used for a variety of mental health concerns, such as anxiety, OCD, etc... Most doctors find out accidentally that a med. has more than one use, and then if the pharmeceutical company wants to spend a lot of money on trials, they can have it approved for those additional uses, extend their patent, market to a greater audience, and make more money, yada, yada, yada...
"I have also heard that Zoloft causes weight gain, does Celexa?"
Both Zoloft and Celexa can go either way. The doctors I work with have found that some people gain on Zoloft and Celexa, and other lose weight. Based on personal experience, my weight has not fluctuated more than 5 pounds on either medication.
"s Prozac, Paxil, Effexor and Celexa basically the same exact medication? If it is, why was Celexa chosen for me? What are the differences between Lexapro, Celexa, Effexor, Paxil and Prozac? I am a little confused about antidepressantsand don't know much about them. This is all new to me!"
See 1st paragraph.
"Here is my most important question, is Celexa going to kill my sex drive? Am I going to have a hard time climaxing? (sorry, I know it is a embarassing question,.... but I need to know!)I have not been on the Celexa long enough to feel the full effect, so I am a little concerned about this."
Please do not fret about embarassment, as I do not blush easily. Again, each of us is unique, so not everyone will experience every side effect, and some people do not experience any. I have found, both personally and professionally, that Zoloft does tend to affect sex drive quite often. However, the good news for you isx that I have not found that to be the case with Celexa. I have been on 20mg of Celexa for a while know, and I have noticed any impact on my sex drive or performance. Hopefully you will have the same luck.
I hope this helps. Any more questions, feel free to ask (no matter how odd).
