Posters are saying that anti-depressants aren't addictive, but taken over a long time they can certainly cause dependence, which is not disimilar from addiction. The difference is that with addiction you crave more and more of whatever it is, and with dependence, you don't crave more, but you cannot function without them.
I had a severe depression 15 years ago following a berevement and was in psychiatric hospital for 3 months. I stayed on ADs for 14 years because GPs told me I needed to stay on them for life and I believed them. Each time I tried to reduce the dose myself I suffered what I thought were the return of the depression symptoms and GPs agreed with this and told me to go back on the full dose.
It wasn't until I began seeing a psychologist with an expertise in mental health that I understood that what I had been experiencing when I tried to reducwe the dose was withdrawal symptoms because of my dependence on the drugs. She showed me how to come off them safely and I managed to do this 1 year ago.
I am not saying that this dependence occurs with people who are on ADs for a reasonable time but I know that it happened for me and GPs did NOT know that I was getting withdrawal symptoms and told me the depression had returned because I had reduced the dose which was not the case. In my view most GPs knowledge about mental health is limited, as it is something that is not given a great deal of attention in their training.
SO I think it is important to bear in mind these things when taking these sort of drugs.
I think the thing is is to not stay on them for too long as I am sure that this is what caused the problem for me. Once I knew how to come off them safely it was fine and I did it very slowly over a 10 month period. also the GPs had no idea how to help me come off them safely and told me to reduce far too quickly which caused withdrawal symptoms again.
If anyone wants advice on how to come off the safely I will be happy to share with you what the psychologist told me to do - it was very simple but effective.
