Hi caesarsmama,
i have heard of all three of these medicines, and they are all antidepressants (i'm pretty sure the celexa is, other two are for sure). I don't know what the differences are, but I take effexor xr, and it helps a lot for the depression, I know that. How long have you been taking the medicines? And are you seeing a psychiatrist, or a family Dr.? What doseages have you taken? It does take 4 to 6 weeks often for the medicines to reach their full effect, and you do need an ample dose of the medicine in order for it to be effective. Often our family Dr.'s will just give us one pill and tell us "come back if it doesn't work". This is what happened with me, and I wasn't getting the full benefit of the medicine, because it was too low of a dose. Also, I might add, that what works for one person, doesn't always work for another, so it might take some time for you to find what exactly will work for you, and you may need to combine medicines to get the effect you need. So, don't give up, and keep bugging the Dr. Until you find what works best for you. But, also be sure to give each medicine a fair trial before changing to another one. A psychiatrist is best equipped to know the best medicines, but if you aren't able to get one, do use your family Dr. Until you can see a psychiatrist. Good luck, and keep us posted on how things go.
