It just so happens that the anti-depressant that my psychiatrist started me on some six months ago, is Citalopram (Celexa). I am on 20 mg, which is the lowest therapeutic dose, and that is working very well for me.
If you are placed on Citalopram, or any anti-depressant for that matter, make sure you start out at a low dose, and slowly increase it. This helps to ease side effects of the medication. To give you an example, if you are prescribed Citalopram, start out at 5 or 10 mg (but not more than 10), and increase it by 5 or 10 mg ever 7-10 days. The dose range for Citalopram is a minimum of 20 mg (the lowest therapeutic dose), to a maximum of 40 mg.
Jonny, I was having problems with bad thoughts, was having anxiety 24/7 with some panic attacks, and there was a little depression there too. After about 3 weeks of being on 20 mg, I really noticed a decrease in my bad thoughts and the depression. Also the panic attacks had really dropped off, and the ones I did have were no longer severe. For me the anxiety lasted the longest, but that really started falling off at about 10 weeks into the therapy.
I hope this information helps.
As always, the very best to you, Jonny!... Chuck
